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.

The 10 Essential Habits of Positive People

The 10 Essential Habits of Positive People

Are you waiting for life events to turn out the way you want so that you can feel more positive about your life? Do you find yourself having pre-conditions to your sense of well-being, thinking that certain things must happen for you to be happier? Do you think there is no way that your life stresses can make you anything other than “stressed out” and that other people just don’t understand?  If your answer is “yes” to any of these questions, you might find yourself lingering in the land of negativity for too long!

The following are some tips to keep positive no matter what comes your way. This post will help you stop looking for what psychologists call “positivity” in all the wrong places!  Here are the ten essential habits of positive people.

1. Positive people don’t confuse quitting with letting go.

Instead of hanging on to ideas, beliefs, and even people that are no longer healthy for them, they trust their judgement to let go of negative forces in their lives.  Especially in terms of relationships, they subscribe to The Relationship Prayer which goes:

 I will grant myself the ability to trust the healthy people in my life … 

To set limits with, or let go of, the negative ones … 

And to have the wisdom to know the DIFFERENCE!

 2.  Positive people don’t just have a good day – they make a good day.

Waiting, hoping and wishing seldom have a place in the vocabulary of positive individuals. Rather, they use strong words that are pro-active and not reactive. Passivity leads to a lack of involvement, while positive people get very involved in constructing their lives. They work to make changes to feel better in tough times rather than wish their feelings away.

3. For the positive person, the past stays in the past.

Good and bad memories alike stay where they belong – in the past where they happened. They don’t spend much time pining for the good ol’ days because they are too busy making new memories now. The negative pulls from the past are used not for self-flagellation or unproductive regret, but rather productive regret where they use lessons learned as stepping stones towards a better future.

4. Show me a positive person and I can show you a grateful person.

The most positive people are the most grateful people.  They do not focus on the potholes of their lives.  They focus on the pot of gold that awaits them every day, with new smells, sights, feelings and experiences.  They see life as a treasure chest full of wonder.

5. Rather than being stuck in their limitations, positive people are energized by their possibilities.

Optimistic people focus on what they can do, not what they can’t do.  They are not fooled to think that there is a perfect solution to every problem, and are confident that there are many solutions and possibilities.  They are not afraid to attempt new solutions to old problems, rather than spin their wheels expecting things to be different this time.  They refuse to be like Charlie Brown expecting that this time Lucy will not pull the football from him!

6. Positive people do not let their fears interfere with their lives!

Positive people have observed that those who are defined and pulled back by their fears never really truly live a full life. While proceeding with appropriate caution, they do not let fear keep them from trying new things. They realize that even failures are necessary steps for a successful life. They have confidence that they can get back up when they are knocked down by life events or their own mistakes, due to a strong belief in their personal resilience.

7. Positive people smile a lot!

When you feel positive on the inside it is like you are smiling from within, and these smiles are contagious. Furthermore, the more others are with positive people, the more they tend to smile too! They see the lightness in life, and have a sense of humor even when it is about themselves. Positive people have a high degree of self-respect, but refuse to take themselves too seriously!

8. People who are positive are great communicators.

They realize that assertive, confident communication is the only way to connect with others in everyday life.  They avoid judgmental, angry interchanges, and do not let someone else’s blow up give them a reason to react in kind. Rather, they express themselves with tact and finesse.  They also refuse to be non-assertive and let people push them around. They refuse to own problems that belong to someone else.

9. Positive people realize that if you live long enough, there are times for great pain and sadness.

One of the most common misperceptions about positive people is that to be positive, you must always be happy. This can not be further from the truth. Anyone who has any depth at all is certainly not happy all the time.  Being sad, angry, disappointed are all essential emotions in life. How else would you ever develop empathy for others if you lived a life of denial and shallow emotions? Positive people do not run from the gamut of emotions, and accept that part of the healing process is to allow themselves to experience all types of feelings, not only the happy ones. A positive person always holds the hope that there is light at the end of the darkness.  

10. Positive person are empowered people – they refuse to blame others and are not victims in life.

Positive people seek the help and support of others who are supportive and safe.They limit interactions with those who are toxic in any manner, even if it comes to legal action and physical estrangement such as in the case of abuse. They have identified their own basic human rights, and they respect themselves too much to play the part of a victim. There is no place for holding grudges with a positive mindset. Forgiveness helps positive people become better, not bitter.

How about you?  How many habits of positive people do you personally find in yourself?  If you lack even a few of these 10 essential habits, you might find that the expected treasure at the end of the rainbow was not all that it was cracked up to be. How could it — if you keep on bringing a negative attitude around?

I wish you well in keeping positive, because as we all know, there is certainly nothing positive about being negative!
