Every one knows how important water is, heck 71% of the Earth is covered is water. The human body is
Here's the break down...
Muscle is 75% water
The Brain is 90% of water
Bone is 22% of water
Blood is 83% water
Every system in our body depends on water. Some things water does are flushes toxins out of vital organs, carries nutrients to your cells, helps with metabolism and helps our organs to absorb nutrients better.Other reason to drink lots of water; it helps you lose weight. Water flushes down the by-products of fat breakdown. Drinking water also reduces hunger, it’s an effective appetite suppressant so you’ll eat less. Plus, water has zero calories. Water also helps you regulate body temperature, and fuel your muscles while working out. Proper hydration helps keep the joints and muscle lubricated so you're less likely to get cramps and sprains.
As I mention before drinking water helps flush out your system so you are less likely to get sick.
Water helps to replenish skin tissues, moisturizes skin and increases skin elasticity. So drinking water can help keep wrinkles and dry skin at bay.
Since the brain is mostly made up of water, drinking water helps you think better, be more alert and more concentrated.
Another cool thing I found out is that your body has to heat up the stuff you drink to body temperature. Which mean you burn calories to do that. You burn about one calorie for every fluid ounce of water you drink, but this only counts if the water is really ice cold. Say you drink a liter of ice cold water, that's around an extra 32 calories burned without doing any extra physical activity. Sure it doesn't sound like much but, if you drink only one liter of ice-cold water everyday that's about an extra 224 calories per week, 896 calories per month and 10,752 per year which is equal to 3 pounds of fat that you will have lost (or at least not gained) by simply drinking cold water. Pretty cool, no?
