  • Six Reasons Why Water is So Critical to Your Health

    Six Reasons Why Water is So Critical to Your Health

    Water is the single most critical nutrient to your body. Therefore, drinking sufficient water is essential to your health and, because it is excreted by the body in various ways all day long, it’s important to replace it throughout the day. When your water intake does not equal your output, you become dehydrated.

    Fluid losses occur continuously — from skin evaporation, breathing, urine and stool — and these losses must be replaced daily to maintain good health. Even mild dehydration can cause daytime fatigue.

    I’ve long been a proponent of drinking a tall glass of water upon waking each morning, before breakfast or even coffee. Caffeine is a diuretic, meaning it increases your urine output. For roughly every 100 milligrams of caffeine you consume – the approximate amount in one cup of coffee or two cups of black tea – you should drink an additional cup of water to compensate for the drug’s diuretic effect (yes, caffeine is a drug).

    Your body also excretes water while you sleep, through perspiration and breathing. So even if you’re not a coffee drinker, this lost water should be replaced immediately each morning.

    Fluid losses are heightened during strenuous exercise, in warmer climates, at high altitudes and in older adults, whose sense of thirst may not be as discerning.

    Here are six prime reasons to make sure you’re drinking enough water every day:

    1. Drinking Water Helps Maintain Every System in Your Body

    Your body is composed of about 60% water. The lungs are about 83% water; the muscles and kidneys are 79% water; the brain and heart are composed of 73% water; and even the bones are 31% water.

    Your body fluids are critical to digestion, absorption, circulation, transportation of nutrients, creation of saliva and maintenance of body temperature.

    Body fluids transport waste products in and out of cells. The main toxin in the body is blood-urea nitrogen, a water-soluble waste that is able to pass through the kidneys to be excreted in the urine.

    When you’re getting enough fluids, urine flows freely, is light in color and free of odor. When your body is not getting enough fluids, urine concentration, color and odor increase because the kidneys trap extra fluid for bodily functions.

    2. Water Can Aid Weight Loss

    Water is a great appetite suppressant because it makes you feel fuller. Drinking a glass of water before meals can curb your appetite, helping you eat less without feeling hungry. Since water is 100% calorie-free, substituting it for higher-calorie beverages can help with weight loss.

    Water also helps you burn more calories. The amount of calories burned by the body at rest is known as resting energy expenditure. In adults, resting energy expenditure has been shown to increase by 24–30% within 10 minutes of drinking water. This lasts at least 60 minutes. The effects are heightened by cold water. When you drink cold water, your body uses extra calories to warm up the water to body temperature.

    Two separate studies showed that increasing water intake to over 1 liter (34 oz) per day resulted in an extra 4.4 pounds of weight loss over a 12-month period. That’s roughly 17,000 additional calories burned annually.

    Water also increases the body’s ability to metabolize stored fat. Inadequate water intake can cause fat deposits to increase, while sufficient water intake can actually reduce fat deposits.

    3. Water Helps Build Muscles

    Muscle cells need to maintain a balance of fluids and electrolytes to avoid fatigue, weakness and shrinking. In short, inadequate fluid intake can cause performance to suffer. Again, your muscles are 79% water.

    Research has shown that when cells lose water, protein production can slow down and protein breakdown can speed up. This could hamper post-exercise muscle protein synthesis. Greater muscle breakdown results in less new-muscle growth.

    Aerobic performance, such as running or cycling, can decrease when body weight drops just 2-3% as a result of dehydration. Power generation can also become compromised with the loss of just 3% in body weight.

    Researchers determined that when test subjects were dehydrated by 3%, total repetitions performed were significantly lower. The subjects also perceived the exercises as more difficult and they needed longer for their heart rates to recover.

    4. Water is Critical to a Healthy Digestive Process

    Adequate water helps to maintain a normal digestive tract. It helps to properly metabolize food and transport nutrients.

    Water also helps to maintain normal bowel function; adequate hydration can prevent constipation.

    5. Water is Vital to Healthy, Good-Looking Skin

    Your skin contains 64% water. Dehydration makes your skin look dry and wrinkled. Proper hydration may help prevent wrinkles and may even decrease some. Being well hydrated can also help rid the skin and body of toxins.

    Healthy, well-hydrated skin also easily absorbs water from moisturizers and creams, increasing the benefit of skincare products.

    6. Sufficient Water Intake is Important for Your Heart

    Your heart pumps about 2,000 gallons of blood a day and it is able to pump blood more easily when well-hydrated, allowing it to work more easily and efficiently. Water also helps maintain blood pressure. Dehydration can cause blood to become thicker, increasing blood pressure.

    Dehydration causes strain on your heart because your blood volume decreases when you are dehydrated. This results in your heart beating faster and working harder. Water delivers oxygen throughout the body. Blood, which is more than 90 percent water, carries oxygen to all parts of the body.

    How Much Water Should You Drink?

    The National Academy of Medicine (NAM) recommends a total daily water intake of 3.7 liters (15 cups) for the average adult male and 2.7 liters (11 cups) for the average adult female.

    Water needs vary tremendously, according to the individual, and are dependent on factors such as temperature, altitude and activity level. If you’re exercising, you need more water than when you’re sedentary. People who exercise regularly may need more daily water intake than those who are not very active.

    The American College of Sports Medicine’s guidelines recommend that people drink about 17 ounces of fluid roughly two hours before exercise. During exercise, they recommend that people start drinking fluids early, and drink them at regular intervals to replace fluids lost by sweating.

    Eating more fruits and vegetables can aid hydration due to their high water content. About 20% of our fluid intake comes from foods. Having a beverage with every snack and meal will increase hydration.

    Drink plenty of water. Eat healthy. Sleep plentifully. Stay healthy.

     

  • Don’t Fall Prey to Sitting Disease!

    Don’t Fall Prey to Sitting Disease!

     

    The Benefits of Standing vs Sitting

    The Mayo Clinic conducted a 10-year, $20 million research study on nutrition, activity and behavior related to weight management and obesity prevention.
     
    The research determined that sedentary environments are a primary contributor to the rise in obesity that increases health costs and takes a toll on quality of life.
     
    This research supported the value of N.E.A.T. (Non-Exercise Activity Thermogenesis), which is all the calories one burns while doing normal, non-exercise activity.
     
    Much of our health depends upon adequate, regular movement. In fact, all movement counts toward our health, and non-exercise activity is crucial. Our bodies were designed to move and when we don’t, our physical health deteriorates.
     
    One culprit driving the obesity epidemic is “sitting disease.” Most of us spend 10-15 hours a day just sitting!
     
    No matter how much you exercise, sitting for excessively long periods of time is a risk factor for early death, according to a 2017 study in Annals of Internal Medicine.
     
    There’s a direct relationship between time spent sitting and your risk of early mortality of any cause, researchers said, based on a study of nearly 8,000 adults. As your total sitting time increases, so does your risk of an early death.
     
    The positive news: people who sat for less than 30 minutes at a time had the lowest risk of early death.
     
    Replacing a few hours of sitting at your desk with standing can lead to significant health benefits over time. In addition to the cardiovascular and musculoskeletal benefits, there is also a significant difference in calories burned.
     
    A study by the BBC and the University of Chester found remarkable health benefits of standing versus sitting. Standing caused participants to have a much higher heart rate (around 10 beats per minute higher), which adds up to burning about 50 calories more per hour versus sitting. Over a year, that adds up to about 30,000 more calories or 8 pounds of fat.
     
    There are many documented benefits of standing, such as reducing your risk of type 2 diabetes, cardiovascular disease, certain types of cancer and back pain.
     
    The general rule is to not sit more than 30 minutes without standing or getting up and moving. Set an alarm on your watch, phone or computer to remind you to get up after you’ve been sitting for 30 minutes. Move around or walk for five minutes to help reduce the health risks from all that sitting.
     
    Get in Motion. Stay in Motion.
  • Some Simple Diet Recommendations

    Some Simple Diet Recommendations

    In America today, people are more likely to be overnourished than undernourished.

    In 2017, the Centers for Disease Control and Prevention found that almost 40 percent of American adults and nearly 20 percent of adolescents are obese — the highest rates ever recorded for the U.S. 

    In total, more than 70 percent of Americans are now either overweight or obese, meaning that an unhealthy weight has become the norm, with healthy-weight Americans — who have a BMI of less than 25 — now in the minority.

    Yet, while we are a nation of overnourished individuals, many Americans are still malnourished. Despite the overabundance of calories (Americans eat an average of over 3,600 calories a day, according to a report by The Food and Agriculture Organization), many Americans don’t get enough healthy calories.
     
    The most recent edition of the Dietary Guidelines for Americans recommends that adults consume 1.5-2 cups of fruit per day and 2-3 cups of vegetables per day. 
     
    However, about 90 percent of Americans dont eat enough fruits and vegetables, according to a 2017 CDC report. Specifically, just 12.2 percent of American adults are meeting the standard for fruit and 9.3 percent are meeting the standard for vegetables.  
     
    Fruits and veggies are nutrient-dense, meaning they are full of beneficial nutrients and minerals, while containing no added sugars or sodium. Every calorie they contain is very beneficial to the human body. 
     
    These healthy, natural foods are also packed with fiber, which aids digestion and can help treat digestive problems, while preventing constipation and potentially reducing cholesterol levels. Adequate fiber intake may also help protect against heart disease, type 2 diabetes and some forms of cancer.
     
    Since the vast majority of Americans are coming up short with their fruit and vegetable intake, many are also missing some key nutrients in their diets.
     
    According to the most recent U.S. Dietary Guidelines, there are seven important nutrients in foods that most Americans aren’t getting in sufficient amounts:
     
    • Fiber
    • Calcium
    • Potassium
    • Magnesium
    • Vitamin A
    • Vitamin C
    • Vitamin E
     
    Though each of the above can be found in the form of nutritional supplements, it’s always best to get all of our nutritional needs met through a well-rounded diet, anchored by fruits, vegetables, whole grains and lean proteins. As the name suggests, supplements are supposed to supplement a healthy diet. Studies have found that they don’t offer as many health benefits as the nutrients naturally found in food. That said, most nutritionists agree that a multivitamin is an inexpensive insurance policy.
     
    One macronutrient that most Americans eat in abundance is protein. Proteins are vital components of the human body, critical to the repair of tissue and the building of bones, muscles, cartilage, skin and blood. Proteins also help to regulate hormone production and make us feel full. 
     
    The U.S. Dietary Guidelines state that adults should take in a minimum of 10 percent of their daily calories from protein. Most Americans take in about 15 percent of their calories from protein. The healthy range for protein extends up to 35 percent of daily calories, according to the guidelines. The current 15 percent protein intake of the average American, combined with regular exercise, is sufficient to maintain muscle, according to Harvard Medical School.
     
    Most of us get a significant portion of our protein in the form of animal proteins. However, we’d all be well-served to eat plant proteins more often. Good sources include beans (kidney, pinto, black or white beans), peas (split peas, chickpeas, hummus), soy beans (edamame) or soy products (tofu, tempeh, veggie burgers), as well as nuts and seeds. These are all naturally low in saturated fat and high in fiber.
     
    The point is to get our proteins from a wide variety of sources and to make sure we’re getting what are known as “complete proteins.”
     
    There are 20 different amino acids that can form a protein, nine of which the body can’t produce on its own. These are called essential amino acids—we need to eat them since we can’t make them ourselves. In order to be considered complete, a protein must contain all nine of these essential amino acids in roughly equal amounts.
     
    Examples of complete proteins include meat, poultry, fish, eggs, milk, cheese, yogurt and soybeans. 
     
    Though most plant proteins are considered to be incomplete, combining them can create complete proteins. We don’t need to ingest every essential amino acid in every meal; we only need a sufficient amount of each amino acid every day.
     
    Here are some examples of complete proteins that are also meatless: quinoa, buckwheat, lentils and rice & beans.
     
    Vegans and vegetarians may have to work a little harder to consume complete proteins, but the following may be helpful: Every time legumes (such as beans, lentils and peanuts) are combined with grains like wheat, rice and corn, a complete protein is created. Peanut butter on whole wheat is perfect example. This snack provides all the essential amino acids, as well as some healthy fat.
     
    That leads us to another vital macronutrient: fats, most especially healthy fats. These include: avocados/avocado oil, nuts (walnuts, pecans, pistachios, cashews and almonds), seeds (flax, sunflower, chia), nut butters, olives/extra virgin olive oil, coconut/coconut oil, and fatty fish (salmon, mackerel, herring, sardines, albacore tuna).

    Here are some simple recommendations:

    Eat a salad every day and have vegetables with every meal. Snack on fruits. Eat more plant-based proteins and make sure to combine them so that they create complete proteins. Limit saturated fats and focus instead on healthier monounsaturated fats (olives, avocados, nuts, seeds) and healthy oils (olive-mono, avocado-mono, flaxseed-poly and grapeseed-poly) and polyunsaturated fats, the latter of which contain the omega-3 fatty acids found in fatty fish, flaxseed and walnuts, for example. 

    As Hippocrates famously said, “Let food be thy medicine and medicine be thy food.”

  • Walking Has Many Benefits, Even for Runners

    Walking Has Many Benefits, Even for Runners

     

    While running is more physically demanding than walking, the latter is still a good form of exercise and a great recovery tool for runners. Running the same speed and distance each day can lead to plateauing. Walking, which is lower impact, can allow your body to recover and enable better results over the long term.
     
    Running will lead to greater cardiorespiratory fitness than walking, as well as more calories burned in an equal period of time. However, walking is a better alternative for people with ankle, knee or back injuries (including recent surgeries), as well as for people who are obese. Walking puts less stress on joints and can reduce the pains associated with running.
     
    Like running, walking can improve heart health, improve circulation and improve posture. Walking can also help reduce the risk for high blood pressure, high cholesterol, diabetes, heart disease and even cancer.
     
    The key is to walk with a sense of purpose by engaging in at least moderate-intensity walking. Walking can even be a form of interval training. By repeatedly raising and lowering your speed and (if you are on a treadmill) the incline, you can also raise and lower your heart rate intermittently, which is a great calorie burner. You can even intersperse short runs, of say a block or two or a minute or two, into your walks. 
     
    Walking uphill or on an incline places more demand on the body, particularly the leg muscles. You’ll notice it in your heart rate, as well. The higher you set the incline on the treadmill, the more you activate your glutes, quadriceps and calves, and the more energy you use. That means more calories burned.
     
    One common mistake that people make when using a treadmill is holding onto the handrails. This takes away from muscle engagement and the energy required to walk or run at the level you set. Remember, there are no handrails when you walk outside and you manage that quite well!
     
    Like running, walking can clear your mind, improve mood,nd alleviate anxiety and depression.
     
    So, put on some comfy athletic shoes, get hydrated and get in motion.
  • Beware the Liquid Calories

    Beware the Liquid Calories

    Whether you are trying to lose weight or just maintain it, it’s a good idea to limit your intake of liquid calories. Most Americans only count the calories they get from solid foods, and many are unaware of how liquid calories are sneaking into their diet and affecting their body weight.
     
    A study commissioned by the Milk Processor Education Program found that liquids make up 22 percent of calories in the average American’s diet.
     
    As of 2016, the average American drank about 39 gallons of soda a year—or about eight 12-ounce cans a week—according to the Beverage Marketing Corp.
     
    Yet, soda isn’t the only culprit. Though soda sales have fallen, Americans are still getting lots of unnecessary calories from fruit juice, fruit drinks, sports drinks, energy drinks, sweetened teas and sweetened coffee beverages. In fact, sugar drinks are the single-largest source of calories from added sugar in the American diet.
     
    A typical 12-ounce can of regular cola contains nearly 9 teaspoons of added sugars; a 20-ounce bottle contains 15.5 teaspoons of sugars. Yet, the American Heart Association recommends a maximum daily intake of 6 teaspoons of added sugars for women and 9 teaspoons for men.
     
    Sodas are the perfect example of empty calories. There is virtually no nutrition or useful quality in soda, which is full of unhealthy additives and preservatives, such as artificial colors, phosphoric acid and bicarbonate. This is why cutting back on liquid calories may be more valuable than cutting back on calories from solid food.
     
    Generally speaking, calories from fluids are not satiating and don’t suppress hunger, which means you can consume a lot of liquid calories without ever feeling full. That can lead to overconsumption and weight gain.
     
    After you ingest sugar, glucose enters your bloodstream and your pancreas immediately begins making insulin to balance the rush of sugar. Most sweetened drinks contain both glucose and fructose. Glucose is quickly turned into energy, while fructose, which is sweeter, is more likely to turn into fat.
     
    Fructose is sent to the liver, where it is converted to be burned as fuel. The excess stored away as fat. There is research on sugar intake suggesting that this fat ends up as belly fat.
     
    If you’re trying to lose weight or just trying to maintain it, your best beverage choice is water, which is calorie free. Water helps cleanse your body of unhealthy and unneeded waste, and helps your body function properly. Most of your body — as much as 65 percent — is composed of water.
     
    If you get hungry between meals, drink a glass of water and snack on fresh fruits and vegetables. Whole fruits and vegetables contain fiber and are therefore much more filling than juice. Critically, fruits and veggies are nutrient dense, while being low in calories.
     
    Although energy drinks are touted as healthy, some can have as much added sugar as sodas. Energy is just another word for calories. In fact, in England, calories are referred to as energy. If you’re not exercising for 45 or more minutes, why would you need an energy drink? If they were called “calorie drinks,” people would be a lot more cautious about consuming them.
     
    Other than water, remember that serving sizes matter. Beverage cans and bottles of 6 or 7 ounces were once commonplace. These days, it’s tough to find retail beverages offered in anything less than 12, 16 or even 20 ounce containers. All of those additional ounces represent additional calories.
     
    Lastly, if you think you’re doing yourself a favor by drinking artificially sweetened beverages, you’re not. Studies show that artificial sweeteners alter your metabolism and increase your sweet tooth. Artificial sweeteners are synthetic and intensely sweet, much more than regular sugar itself. They make you want more sugar, which means consuming more calories in the long run.
     
    Research on these sugar substitutes connects diet soda consumption to metabolic syndrome, Type 2 Diabetes and chronic kidney disease. A nine-year study, which followed older adults who drank diet soda daily, showed a 48 percent higher risk of stroke, heart attack and even death. Steer clear.
     
    Remember that liquid calories in just about any form — alcohol, juice or soda — are stealth calories. They are often imperceptible, but they can have an enormous impact on your weight status, as well as your overall health.
  • Is Your Weight Training Intensity Adequate?

    Is Your Weight Training Intensity Adequate?

    Through many years at the gym, I’ve often seen women using the same 5-pound dumbbells for a variety of exercises: chess presses, shoulder presses, rows, bicep curls, lateral raises, front raises and more. Since weights should be thought of as tools, this is tantamount to using a screwdriver for every task, when sometimes you need a hammer or a wrench.
     
    For example, the weight you use for a chest press should be heavier than the weight you use for a shoulder press, which should he heavier than the weight you use for a lateral raise.
     
    As you work out consistently, you should grow stronger over time, necessitating the use of heavier weights for each exercise. This is especially true in the early stages of a workout program, when strength gains are most pronounced.
     
    It’s not just women either. I’ve often seen men using the same 25-pound dumbbells for an exercise that they’ve been performing for years. They make no progress because their program is not built on progression.
     
    Your body is a demand-based system. That is, the more you demand of it, the more it will produce. If you don’t steadily, but incrementally, increase the demand, your workouts and your results will stagnate.
     
    Aside from the fact that you shouldn’t be lifting the same exact weight for a variety of exercises, you shouldn’t be lifting the same exact weight for the same exercise, week after week, month after month.
     
    In short, weight training is meant to be progressive. You shouldn’t be lifting the same amount of weight today that you did one year ago. You should have gotten stronger; you should have progressed.
     
    However, sometimes your body needs a break from heavy lifting. Take it easy once a week and work on muscular endurance instead of just strength. Give your muscles a break, while still remaining active in the gym.
     
    How do you know if you are (or are not) using a high enough weight, aka, working out at the proper intensity?
     
    First, let’s define intensity, which is based on the maximum number of repetitions that can be performed with a given weight. The one-repetition maximum (1RM) is an ideal baseline:
     
    • High Intensity = 80–100% of your 1-rep max (1RM); typically 1-5 reps
    • Medium Intensity = 60–80% of your 1-rep max (1RM); 6-12 reps
    • Low Intensity = 10–40% of your 1-rep max (1RM); 15 or more reps
     
    The National Strength and Conditioning Association (NSCA) provides the following guidelines:
     
    • Hypertrophy (muscle growth) = 6-12 RM
    • Strength = 6, or fewer, RM
    • Power = 1-2 RM
     
    In order for your muscles to undergo an adaptation from training (i.e., to grow stronger or bigger), they must be stressed by working against a weight/load/stimulus that is greater than what they are accustomed.
     
    Don’t stop an exercise simply because you have reached 10 or 12 reps. Perform each exercise to the point of momentary muscular failure, whether that’s 12, 10, eight or six reps.
     
    Increasing weight means a reduction of reps. If, for example, you can chest press 40-pound dumbbells 10 times to failure, that means you shouldn’t be able to press 50-pound dumbbells 10 times (if you can, you should be working out with the 50s, not the 40s). It’s likely that you can only press the 50s six times or eight times, or whatever it might be.
     
    If the current weight you are lifting isn’t challenging, you need to increase that weight. Strength training is meant to be challenging, because the whole point is to “overload” your muscles so they become stronger.
     
    Simply put, if you can do more than 12 repetitions, you should increase the weight. Everyone could stand to be stronger. 
     
    If you determine that it’s time to increase your resistance for a particular exercise, do this by adding no more than 10 percent at a time. For example, if you’re currently lifting 50 pounds, you’d increase that by five pounds to 55 pounds. This incremental increase should keep you safe and prevent injury. It’s important to maintain good form with a new, higher weight.
     
    Remember, if you don’t make your muscles work harder than they’re accustomed, they won’t get stronger (which is the whole point). If you train progressively, your muscles will grow stronger in order to meet the increasing demands you are placing on them.
     
    Lastly, recognize that some days you will feel like the Incredible Hulk, while on other days you will feel like a mere mortal. It’s okay; it’s all part of the process. Don’t beat yourself up over a bad training day. We all have them from time to time. 
  • Wash Your Hands Before Leaving Gym to Prevent Illness

    Wash Your Hands Before Leaving Gym to Prevent Illness

     

    You go to the gym to be fit and healthy. However, gyms are breeding grounds for germs that can make you sick and unhealthy.
     
    Because so many people handle things such as free weights, weight machines, exercise balls, etc., this equipment is often rife with bugs and viruses that can lead to colds, flu and other infections.
     
    Exercise equipment, including exercise mats, can also hold microbes that may cause skin infections, athlete’s foot and even hepatitis A.
     
    For example, norovirus, which causes stomach pain, vomiting, and diarrhea, can survive for a month on the surface of exercise machines.
     
    There are even cases of MRSA, an antibiotic-resistant bacteria that can lead to dangerous skin infections, being found on gym equipment.
     
    That’s not all.
     
    Fungi and bacteria — such as E. coli, staph and fecal matter, as well as vaginal yeast — have all been detected at gyms across the country.
     
    If that wasn’t bad enough, streptococcus — which causes various illnesses, from strep throat, to pink eye, to meningitis and bacterial pneumonia — can survive on doorknobs and other surfaces, such as sweaty exercise equipment.
     
    The simple solution to avoid getting sick is to wash your hands before and after your workout. Touching your eyes, nose or mouth with unwashed hands at the gym, or after leaving, is a surefire way to invite sickness.
     
    Just touching your steering wheel with unwashed hands after leaving the gym can transfer bacteria that may survive there for weeks, increasing your chances for infection even when you haven’t recently been to the gym.
     
    If you shower at the gym, always wear flip-flops to avoid athletes’ foot (a foot fungus caused by candida) and plantar warts, which are caused by the HP virus.
     
    The key is not to be paranoid and to avoid the gym, but to instead be aware and cautious. Thoroughly washing your hands is a very simple, preventative measure. Just do it.
  • Sleep Vital to Muscle Recovery, Muscle Growth and Weight Management

    Sleep Vital to Muscle Recovery, Muscle Growth and Weight Management

     

    Since we were children, we’ve all heard the advice that we should get eight hours of sleep each night. With 24 hours in a day, that amounts to a third of the day and, ultimately, a third of our lives.
     
    Unfortunately, most of us are missing the mark.
     
    The National Sleep Foundation recommends 7-9 hours of sleep per night. However, it says that around 40 percent of us get less than 7 hours. Moreover, a survey by Gallup finds that Americans currently average 6.8 hours of sleep at night, down more than an hour from 1942.
     
    Life has gotten faster and more hectic at the expense of our sleep and, ultimately, our health.
     
    Scientists are still discovering the myriad of reasons we need sleep and just how valuable it is. For example, in studies on rats deprived of sleep for just five days, the end result was death. Sleep was found to be as essential as food because the rats died just about as quickly from sleep deprivation as from food deprivation.
     
    For athletes and exercise enthusiasts, sleep is vital to athletic performance, as well as muscle growth and recovery.
     
    Protein synthesis occurs when we sleep, provided that protein is ingested prior to sleep. This is why it’s useful to eat some protein, or drink a protein shake, before bed.
     
    Sleep is also the time when our bodies produce growth hormone. In men, 60% to 70% of daily growth hormone secretion occurs during the early stages of sleep, which is typically when the deepest sleep cycles occur. Consequently, poor quality sleep can negatively effect human growth hormone levels.
     
    Additionally, the total amount of growth hormone secreted by men in their 30s and 40s deceases significantly, meaning that sleep becomes even more vital as we age.
     
    Yet, sleep is vital at every age. Research shows that sleep deprivation in otherwise healthy young men can result in decreased testosterone levels and increased spikes of cortisol, a stress hormone.
     
    Furthermore, lean muscle is regenerated in the final couple of hours of sleep each night. During REM (late-stage) sleep, the body undergoes several critical processes, including: restoring organs, bones and other tissues; replenishing immune cells; and circulating human growth hormone. For these reasons, sleep has a significant effect on muscle growth and recovery.
     
    Research shows that being sleep-deprived can actually encourage loss of muscle mass and hinder muscle recovery after a tough workout. Ultimately, sleep is vital in order for the body to grow and repair muscle.
     
    Then there’s the issue of weight management.
     
    Research shows that people who don’t sleep for 7-8 hours a night are more prone to weight gain.
     
    When you’re sleep deprived, leptin (the hormone that signals satiety) falls, while ghrelin (which signals hunger) rises. This combination leads to an increase in appetite. Additionally, sleep deprivation tends to lead to food cravings, particularly for sweet and starchy foods.
     
    Researchers have suggested that these sugar cravings stem from the fact that your brain is fueled by glucose (blood sugar). Therefore, when you lack sleep your brain is unable to properly respond to insulin (which drives glucose into brain cells), so it becomes desperate for carbohydrates to keep going. If you’re chronically sleep deprived, consistently giving in to these sugar cravings will virtually guarantee that you’ll gain weight.
     
    Getting too little sleep also dramatically decreases the sensitivity of your insulin receptors, which will raise your insulin levels. This, too, is a surefire way to gain weight, as the insulin will seriously impair your body’s ability to burn and digest fat. Getting proper sleep is therefore crucial for maintaining a healthy weight.
     
    Several large-scale studies from all over the world have reported a link between short sleep times and obesity, as well as heart disease, high blood pressure and stroke. This indicates that we are not biologically designed for sleep deprivation. In fact, other than humans, there is no other mammal that deprives itself of sleep. This deprivation puts great stress on the mind and body.
     
    Sleep deprived subjects are found to be hungrier, less alert and, most importantly, unable to metabolize sugar effectively, putting them at increased risk for Type 2 diabetes. In one study, in which sleep was restricted to four hours per night for six nights, the subjects ended up in a pre-diabetic state. Consequently, in addition to aging, overweight/obesity and family history, sleep deprivation may be a new risk factor for diabetes.
     
    Research indicates that, aside from proper diet and exercise, sleep must now be viewed as essential to good health. Ultimately, lack of sleep impacts our appetite, our metabolism, our memory and even how we age.
     
    The good news is that napping can help too. Brand new research is showing that long naps, including REM sleep, can even improve emotional outlook, making people less sensitive to negative experiences and more receptive to positive ones.
     
    So, make sure you get about eight hours of restful sleep each night, and don’t worry about sleeping a third of your life away.
     
    Go on, get some sleep.
  • Making Exercise a Habit

    Making Exercise a Habit

    It’s said that old habits are hard to break and new habits are hard to form. This is especially true with exercise. If you are not in the habit of exercising, maintaining that habit is effortless. To begin the habit of exercising, however, takes a lot of resolve, determination and effort.

    The behavioral patterns that are most often repeated become etched into our neural pathways. For this same reason, the process of repetition allows us to form—and maintain—new habits.
     
    Behaviors eventually become routine, which is what happens for people who exercise regularly. For these people, going to the gym or for a run, for example, become routine behaviors, which in time become habits.
     
    Habits are typically governed by reward. In essence, a habit is something your brain likes. Exercise makes people feel good physically and emotionally. After exercising, people usually feel accomplished and proud. Exercise can make you feel that you’ve done something constructive and beneficial for yourself.
     
    The more consistent an action is, the more likely it is to become a habit. This means that exercising every day is more likely to result in habit formation.
     
    One useful idea is to schedule your exercise for a given time each day, as you would with a personal trainer. Accountability is critical to maintaining your schedule and forming a habit.
     
    If you are planning to begin exercising, start modestly. Don’t take on too much, too soon. In other words, don’t set yourself up for failure. Make it easy for yourself to repeat the behavior. Don’t make exercise so strenuous in the initial stages that it gives you good reason not to do it. Make it easy enough that you set yourself up to succeed. Exercise can become progressively more challenging, or difficult, over time.
     
    Don’t become obsessed with results. Just exercising is the only result you should focus on in the beginning. Don’t concern yourself with high intensities or long durations at the outset. The only result that you should be concerned with at the outset is making exercise habitual.
     
    If your goal is to lose weight, don’t obsess on that. Consider the myriad of health benefits that result from exercise; weight loss is merely one of them, even if it comes slowly.
     
    Be aware of any progress that you’re making. Do your clothes fit better? Can you lift heavier weights? Is your endurance or stamina improving? Are you sleeping better? Do you have more energy? Are your muscles becoming less sore after you’ve been working out for a while?
     
    If you’re a morning person, work out in the morning. Stay true to your nature. If you’re not a morning person, don’t try to force yourself to be one. However, if you plan to exercise after work, bring your gear and go straight to the gym. Don’t go home first because it can only give you reasons to stay home and not work out at all.
     
    Alternating your workouts each day between different exercises (running, swimming, biking and strength training, for example) can be invigorating and motivational. At the least, it can fight boredom and repetition. We’ve all heard the saying, variety is the spice of life. So, spice things up by varying your workouts.
     
    Missing a workout does not mean you have broken the habit formation process or that you have ruined your momentum or rhythm. If you miss a day, don’t go on a guilt trip. Just get going again the next day.
     
    The oft-cited assertion that it takes 21 days to form a habit comes from Dr. Maxwell Maltz’s 1960 best-selling book “Psycho-Cybernetics.” Maltz, who noticed that patients tended to grow accustomed to their surgical outcomes in about 21 days, wrote that, “… it requires a minimum of about 21 days for an old mental image to dissolve and a new one to jell.”
     
    Since then, the 21-day adjustment period has been continually repeated as fact. In reality, Maltz wrote that it took a minimum of 21 days for people to adjust. Yet, research suggests that it usually takes significantly longer than that.
     
    For example, in a 2009 European Journal of Social Psychology study, researchers asked 96 people to attempt to forge a single healthy habit.
     
    They found that it took participants anywhere from 18 to a whopping 254 days to fully form their habit of choice; exactly how long it took depended on how big or lifestyle-changing the habit was. However, the researchers concluded that, on average, it takes 66 days to form a single healthy habit.
     
    So, if you can stick to your exercise plan for roughly two months, your consistent behavior should become engrained as habit.
     
    Remember this: Motivation is what gets you started. Habit is what keeps you going.
     
    The beauty of habits is that they hold up even when motivation wanes, according to a scientific review from the University College London’s Health Behaviour Research Centre.
     
    Newton’s law of motion is a good metaphor for the habit of exercise:
     
    “An object at rest stays at rest and an object in motion stays in motion.”
  • Exercise Can Strengthen and Protect Your Arteries

    Exercise Can Strengthen and Protect Your Arteries

     

    Through time and neglect (such as smoking and not exercising, for example), your arteries can become clogged, brittle and otherwise damaged. Healthy arteries are flexible and elastic, which help them to push blood to and from the heart. However, over time, the walls in your arteries can become rigid and inflexible, which is known as hardening of the arteries.
     
    Arteriosclerosis occurs when arteries become thick and stiff, which can restrict blood flow to your organs and tissues.
     
    Atherosclerosis refers to the buildup of plaques — such as fats, cholesterol, calcium and other substances in and on your artery walls — which can also restrict blood flow. These plaques can trigger blood clots. Consequently, atherosclerosis can lead to serious problems, including heart attack, stroke, or even death.
     
    Atherosclerosis may start with damage or injury inside an artery, which can be caused by high blood pressure, high cholesterol, high triglycerides, diabetes and smoking. Blood cells and plaques can lump together at the injury site, building up inside the artery. This causes the arteries to harden and narrow, restricting blood flow.
     
    The good news is that atherosclerosis is treatable and may even be preventable. Exercise, a healthy diet and weight management can all treat atherosclerosis and help prevent it. Of course, exercise is known to aid weight loss, but it has numerous additional benefits for the heart and arteries, as well.
     
    As you age, your arteries become stiffer, stickier and narrower. But scientists in Italy found that in people who exercised regularly, age had a much smaller effect on their arteries.
     
    Exercise keeps arteries healthy by lowering bad cholesterol and boosting good cholesterol. Regular low or moderate-intensity exercise can reduce levels of LDL (bad) cholesterol and fat in your blood and arteries. More intense levels of exercise can raise HDL (good) cholesterol, which protects your heart.
     
    Exercise also reduces other risk factors for atherosclerosis and blood clots, such as high blood pressure, diabetes, obesity and stress.
     
    Additionally, exercise has been shown to reduce inflammation in the arteries and to help keep blood vessels flexible and open. Flexible arteries are elastic and able to stretch, allowing more blood to flow when it’s needed.
     
    This enables your body to maintain its blood pressure level at normal levels, even during exercise or stressful events, which eases the pressure on your cardiovascular system.
     
    The American Heart Association and the Centers for Disease Control and Prevention recommend at least 30 minutes of moderately intense exercise almost every day to make sure that your body remains healthy.
     
    Find exercises that you enjoy and then commit to a long term, regular program. Whatever you do, just get in motion and stay in motion.
