Is Drinking a Lot of Water Good For You?

Is Drinking a Lot of Water Good For You?

There is a common belief that drinking an excessive amount of water is somehow good for the human body.

Many claim that increasing our intake of water can lead to all sorts of health benefits including increased fat burning, less appetite, more energy, etc. But, what does the actual science say about that?

Is there any real benefit to drinking more water than the plain old thirst commands? Or are we just wasting our effort filling and refilling those water bottles all the time? (not to mention having to pee every hour of the day)

First of All, How Much is Too Much?

Before I continue, I should clarify what “a lot of water” means. “A lot of water” implies drinking many glasses of water per day, despite not being thirsty. People who do this often carry water bottles with them everywhere they go, and go to the bathroom to pee all the time.

There is such a thing as “too much water”, which is water intake to the extent that it becomes dangerous. If you drink an insane amount, like in a water drinking contest (very stupid), you may go into a condition known as water intoxication, which can be deadly. The body’s cells need a constant balance of various electrolytes (salts). When you pee and sweat, some electrolytes tend to get out along with the water. Athletes that drink a lot of water to replace intense sweating, without replenishing the body’s salts, may dilute their body fluids. This can mess up the electrolyte balance and cause a condition known as hyponatremia, which can also be deadly.

Therefore, it is important to get in some electrolytes (salts) along with your water if you exercise intensely and sweat a lot. Some sports drinks include the necessary electrolytes to replace what is lost through sweat. But given that you are not participating in a water drinking contest (you’re smarter than that, anyway), and that you make sure to replace massive sweating with both water and electrolytes, then drinking a lot of water is completely safe.

Water and Cognitive Function

Drinking a lot of water isn’t going to make you smarter, but there is a tiny bit of evidence to show that a mild dehydration can slightly impair mental function.

25 healthy women were dehydrated by means of either exercise or diuretics. On average, they lost a little over 1% of their body mass. The women who were dehydrated had an increased perception of task difficulty, less focus, more symptoms of headache, and a degraded mood compared to controls. Thus, it does seem like a good idea to make sure you do not get dehydrated, and take note that 1% of body mass is a very mild dehydration.

If you do feel a little blue at times, then perhaps you’re only a few glasses of water away from feeling your best again.

Water Intake and Bladder Cancer

There was one large-scale prospective study performed on 47.909 health professionals. This study found water intake to be inversely associated with cancer of the urinary bladder, with those who drank 6 or more (1440ml+) cups per day half as likely to get bladder cancer than those drinking less than 1 cup per day (-240ml).

In fact, the authors noted that each additional cup (240ml) lowered the risk by 7%. However, other studies found no protective effect against bladder cancer by drinking more water.

Water and Colorectal Cancer

Several studies show a significant protective effect of water intake against colorectal cancer, which is both common and deadly. In fact it is the third most common cause of cancer death.

These studies show a risk reduction as high as 30-60%, but in some cases they are not statistically significant so they should be taken with a grain of salt.

Fluid Intake and Urinary Health

There is some evidence that drinking plenty of water might reduce chances of recurrence in patients who have been previously diagnosed and treated with kidney stones.

Water as a fat burning beverage

An observational study of 5.783 Chinese adults found that water intake was inversely associated with energy density of the diet, total energy intake and overweight status. Another study in 24 lean women found out that those who ate liquid food (soup) ate a lot less than those who had the same amount of food in solid form. However, eating the solid food with a glass of water on the side had no effect.

I’d like to point out, that despite water with a meal slightly increasing satiety, there is no indication that this would lead to weight loss in the long term, as there are so many other factors at play. There is, however, a small chance that if you stay well hydrated throughout the day, you won’t feel as hungry and won’t eat as much.

If you really want to dig into the whole science behind water intake and health, then I recommend you take a look at this paper (12 – PDF).

Conclusion

In fact, if you don’t drink water for a few days, you will die. If you’re thirsty, water is the way to go. It is clean, calorie free, contains no additives and it’s really the only thing adult humans and pre-humans have been drinking for the last millions of years.

Elderly people may need to consciously make sure to drink water throughout the day as their brain may start to underestimate their required intake. That being said, I do not see any reason why it would be a good idea for young, healthy people to drink a lot more water than what thirst commands. The mechanism in our brain that controls water balance is incredibly efficient.

A common recommendation is eight 8 ounce glasses of water per day (the 8×8 rule). According to the studies above, 5 glasses might be enough. Make sure you don’t get dehydrated, drink 5 glasses of water throughout the day (especially with meals), but definitely increase your intake of water preferably alkaline water before, during, and after workouts to keep ultra-hydrated and to reduce the accumulation of acidity in your exercising muscles for a better workout intensity and recovery time. This less acidic water is available both in bottles and thru specialized machines.

All in all, there doesn’t seem to be any reason to carry a water bottle around all day and drink so much that you have to pee all the time except, of course, when exercising. If you’ve got all that covered, then you have nothing to worry about.

Why You’re Feeling Tired All the Time (and What to Do About It)

Why You’re Feeling Tired All the Time (and What to Do About It)

If you find that you’re feeling tired all the time, it’s important to understand that it’s a common problem for many. With all of the demands of daily life, being tired seems to be the new baseline. In fact, two-fifths of Americans are tired most of the week.[1]

If you’re tired of feeling exhausted, then I’ve got some great news for you. New research is helping us gain critical insights into the underlying causes of feeling tired all the time.

In this article, we’ll discuss the latest reasons why you’re so tired and practical steps you can take to finally get to the bottom of your fatigue and feel rested.

What Happens When You’re Too Tired

If you sleep just two hours less than the normal eight hours, you could be as impaired as someone who has consumed up to three beers.[2] And you’ve probably experienced the impact yourself.

Here are some common examples of what happens when you’re feeling tired:[3]

  • Trouble focusing because memory and learning functions may be impaired.
  • Experience mood swings and an inability to differentiate between what’s important and what’s not.
  • Dark circles under your eyes and/or your skin make look dull and lackluster in the short term and over time your skin may get wrinkles and show signs of aging because your body didn’t have time to remove toxins during sleep.
  • Finding it more difficult to exercise.
  • Immune system may weaken, causing you to pick up infections more easily.
  • Overeating because not getting enough sleep activates the body’s endocannabinoids, even when you’re not hungry.
  • Metabolism slows down, so what you eat is more likely to be stored as belly fat.

Why Are You Feeling Tired All the Time?

Leading experts are starting to recognize that there are three primary reasons people feel tired on a regular basis: sleep deprivation, fatigue, and Chronic Fatigue Syndrome (CFS).

Here’s a quick overview of each common cause of fatigue and feeling tired all of the time:

  1. Tiredness occurs from sleep deprivation when you don’t get high-quality sleep consistently. It typically can be solved by changing your routine and getting enough deep, restorative sleep.
  2. Fatigue occurs from prolonged sleeplessness, which could be triggered by numerous health problems, such as mental health issues, long-term illness, fibromyalgia, obesity, sleep apnea, or stress. It typically can be improved by changing your lifestyle and using sleep aids or treatments, if recommended by your physician.
  3. Chronic Fatigue Syndrome (CFS) is a medical condition also known as Myalgic Encephalomyelitis that occurs from persistent exhaustion that doesn’t go away with sleep.

The exact cause of CFS is not known, but it may be due to problems with the immune system, a bacterial infection, a hormone imbalance, or emotional trauma. It typically involves working with a doctor to rule out other illnesses before diagnosing and treating CFS.[4]

Always consult a physician to get a personal diagnosis about why you are feeling tired, especially if it is a severe condition.

Feeling Tired Vs Being Fatigued

If lack of quality sleep doesn’t seem to be the root cause for you, then it’s time to explore fatigue as the reason you are frequently feeling tired.

Until recently, tiredness and fatigue were thought to be interchangeable. Leading experts now realize that tiredness and fatigue are different.

Advertising

Tiredness is primarily about lack of sleep. However, fatigue is a perceived feeling of being tired that is much more likely to occur in people who have depression, anxiety, or emotional stress and/or are overweight and physically inactive[5].

Symptoms of fatigue include:

  • Difficulty concentrating
  • Low stamina
  • Difficulty sleeping
  • Anxiety
  • Low motivation

These symptoms may sound similar to those of tiredness, but they usually last longer and are more intense.

Unfortunately, there is no definitive reason why fatigue occurs because it can be a symptom of an emotional or physical illness. However, there are still a number of steps you can take to reduce difficult symptoms by making a few simple lifestyle changes.

How Much Sleep Is Enough?

The number one reason you may feel tired is because of sleep deprivation, which means you are not getting enough high-quality sleep.

Research suggests that most adults need 7 to 9 hours of high-quality, uninterrupted sleep per night[6]. If you’re sleep deprived, the amount of sleep you need increases.

Get the right amount of sleep to stop feeling tired.

    The key to quality sleep is being able to get long, uninterrupted sleep cycles throughout the night. It typically takes 90 minutes for you to reach a state of deep REM sleep where your body’s healing crew goes to work.

    Ideally, you want to get at least 3 to 4 deep REM sleep cycles in per night. That’s why it’s so important to stay asleep for 7 or more hours.

    Research also shows that people who think they can get by on less sleep don’t perform as well as people who get at least seven hours of sleep a night[7]

    If you are not getting 7 hours of high-quality sleep regularly, then sleep deprivation is the most likely reason you feel tired all the time. That is actually good news because sleep deprivation is much simpler and easier to address than the other root causes.

    It’s also a good idea to rule out sleep deprivation as the reason why you are tired before moving on to the other possibilities, such as fatigue or Chronic Fatigue Syndrome, which may require a doctor for diagnosis and treatment.

    4 Simple Changes to Reduce Fatigue

    Personally, I’m a big believer in upgrading your lifestyle to uplift your life. I overcame chronic stress and exhaustion by making these four changes to my lifestyle:

    1. Eating healthy, home-cooked meals versus microwaving processed foods or eating out
    2. Exercising regularly
    3. Using stressbusters
    4. Creating a bedtime routine to sleep better

    After I made the 4 simple changes in my lifestyle, I no longer felt exhausted all of the time.

    I was so excited that I wanted to help others replace stress and exhaustion with rest and well-being, too. That’s why I became a Certified Holistic Wellness Coach through the Dr. Sears Wellness Institute.

    Interestingly enough, I discovered that Dr. Sears recommends a somewhat similar L.E.A.N. lifestyle:

    • L is for Lifestyle and means living healthy, including getting enough sleep.
    • E is for Exercise and means getting at least 20 minutes of physical activity a day, ideally for six days a week.
    • A is for Attitude and means thinking positive and reducing stress whenever possible.
    • N is for Nutrition and means emphasizing a right-fat diet, not a low-fat diet.

    The L.E.A.N. lifestyle is a scientifically-proven way to reduce fatigue, get to the optimal weight, and to achieve overall wellness.[8]

    Living Healthy

    Getting enough high-quality sleep every day is the surefire way to help you feel less fatigued, more rested, and better overall.

    In fact, if you aren’t getting enough sleep, your body isn’t getting the time it needs to repair itself; meaning that if you are suffering from an illness, it’s far more likely to linger. In fact, long-term sleep deprivation has been linked to an increase in Alzheimer’s later in life[9].

    As unlikely as it sounds, though, fatigue can sometimes make it difficult to sleep. That’s why I’d recommend taking a look at your bedtime routine before you go to bed and optimize it based on sleep best practices.

    Here are 3 quick and easy tips for creating a pro-sleep bedtime routine:

    1. Unplug

    Many of us try to unwind by watching TV or doing something on an iPhone or tablet. However, tech can affect your melatonin production due to the blue light that they emit, fooling your body into thinking it’s still daytime. This won’t help you stop feeling tired all the time.

    Try to turn off all tech one hour before bed and create a tech-free zone in your bedroom.

    2. Unwind

    Use the time before bed to do something you find relaxing such as reading a book, listening to soothing music, meditating, or taking an Epsom salt bath.

    3. Get Comfortable

    Ensure your bed is comfortable and your room is set up for sleep.

    Make sure you room is cool. 60-68 degrees is the ideal temperature for most people to sleep. Also, it’s ideal if your bedroom is dark and there is no noise.

    Finally, make sure everything is handled (e.g., laying out tomorrow’s clothes) before you get into your nice, comfy bed. If your mind is still active, write a to-do list to help you fall asleep faster.[10]

    Exercise

    Many people know that exercise is good for them, but they just can’t figure out how to fit it into their busy schedules.

    That’s what happened in my case, but when my chronic stress and exhaustion turned into systemic inflammation (which can lead to major diseases like Alzheimer’s), I realized it was time to change my sedentary lifestyle.

    I decided to start swimming because it was something I had always loved to do. Find an exercise you love and stick to it to stop feeling tired all the time. Ideally, get a combination of endurance training, strength training, and flexibility training during your daily 20-minute workout.

    If you haven’t exercised in a while and have a lot of stress in your life, you may want to give yoga a try as it will increase your flexibility and lower your stress.

    Attitude

    Stress may be a major reason why you aren’t feeling well all of the time. At least that was the case with me.

    When I worked 70 hours per week as a High-Tech Executive, I felt chronically stressed and exhausted, but there was one thing that always worked to help me feel calmer and less fatigued: Breathing.

    But not just any old breathing. It was a special form of deep Yogic breathing called the “Long-Exhale Breathing” or “4-7-8 breathing” (or “Pranayama” in Sanskrit).

    Here’s how you do Long-Exhale Breathing:

    Advertising

    1. Sit in a comfortable position with your spine straight and your hand on your tummy.
    2. Breathe in deeply and slowly from your diaphragm with your mouth closed while you count to 4 (ideally until your stomach feels full of air).
    3. Hold your breath while you mentally count to 7 and enjoy the stillness.
    4. Breathe out through your mouth with a “ha” sound while you count to 8 (or until your stomach has no more air in it).
    5. Pause after you finish your exhale while you notice the sense of wholeness and relaxation from completing one conscious, deep breath.
    6. Repeat 3 times, ensuring your exhale is longer than your inhale so you relax your nervous system.

    This type of “long-exhale breathing” is scientifically proven to reduce stress.

    When your exhale is twice as long as your inhale, it soothes your parasympathetic nervous system, which regulates the relaxation response.[11]

    Nutrition

    Diet is vital for beating fatigue if you’re feeling tired all the time – after all, food is your main source of energy.

    If your diet is poor, then it implies you’re not getting the nutrients you need to sustain healthy energy levels, which may lead to daytime sleepiness.

    Eating a diet for fatigue doesn’t need to be complicated or time-consuming though. For most people, it’s just a case of swapping a few unhealthy foods for a few healthier ones, like switching from low-fiber, processed foods to whole, high-fiber foods.

    Here’re 9 simple diet swaps you can make today:

    1. Replace your morning coffee with Matcha green tea and drink only herbal tea within six hours of bedtime.
    2. Add a healthy fat or protein to any carb you eat, especially if you eat before bed.
    3. Fill up with fiber, especially green leafy vegetables.
    4. Replace refined, processed, low-fiber pastas and grains with zucchini noodles and whole grains such as buckwheat, quinoa, sorghum, oats, amaranth, millet, teff, brown rice, and corn.
    5. Swap natural sweeteners for refined sugars, and try to ensure you don’t get more than 25g of sugar a day if you are a woman and 30g of sugar a day if you are a man.
    6. Replace ice cream with low-sugar alternatives.
    7. Swap omega-6, partially-hydrogenated oils such as corn, palm, sunflower, safflower, cotton, canola and soybean oil for omega-3 oils such as flax, olive, and nut oils.
    8. Replace high-sugar yoghurts with low-sugar, dairy-free yoghurts.
    9. Swap your sugar-laden soda for sparkling water with a splash of low-sugar juice.

    Also, ensure your diet is giving you enough of the daily essential vitamins and minerals. Most of us don’t get enough Vitamin D, Vitamin B-12, Calcium, Iron, and Magnesium. If you are low on any of the above vitamins and minerals, you may experience fatigue and low energy.

    That’s why it’s always worth having your doctor check your levels. If you find any of them are low, then try to eat foods rich in them.

    Alternatively, you might consider a high-quality multivitamin or specific supplement.

    The Bottom Line

    If you are tired of feeling tired all the time, then there is tremendous hope.

    If you are tired because you are not getting enough high-quality sleep, then the best remedy is a bedtime routine based on sleep best practices. If you are tired because you have stress and fatigue, then the best remedy are four simple lifestyle changes discussed above.

    Overall, adopting a healthier lifestyle is the ideal remedy for feeling more rested and energized.
