The objective of this proyect was to record the changes in my own body, after a couple of weeks of drinking 2L of water dail.Since water is the healthiest, and most natural beverage in the world, I honestly expect to see a lot of positive changes in my body as well as in my immune system. I hope to be able to see in every different process that my body has, a different improovement to it.


There’s no doubt that water is important.  Not only do we humans use it just about every day, but every livingthing needs it to live.  It has helped form the Earth as we know it, and it covers over 70% of the Earth.  Even where there is land, much of it is covered in ice, which is obviously just solid water.  The importance of water is clear to us in many ways, and we can’t overlook it.
Where would people be without water?  Well aside from, you know, not being alive, we may never have evolved the bigbrains that make us such a unique species.  Some say that that learning how to keep, and transport water over land was the key to our survival when other similar species just kept dying off.
Driking water also brings incountable advantages for the body itself, like skin, hair, organs,muscles,blood, etc. get healthier when you increase your water intake.
Some advantages yout body gets whileincreasing your water intake are:
* Loose weight
* Hydration
* Skin texture
* Digestive health
* Flush our toxins
* Last more at exercise
* Reduce fluid retention
* More energy
Your body is estimated to be about 60 to 70 percent water. Blood is mostly water, and your muscles, lungs, and brain all contain a lot of water. You need water to regulate body temperature and toprovide the means for nutrients to travel to your organs and tissues. Water also transports oxygen to your cells, removes waste, and protects your joints and organs.

You lose water through urination, respiration, and by sweating, and you lose more water when you're active than when you're sedentary. Diuretics, such as caffeine pills, certain medications and alcohol may increase the amount ofwater your body loses. Energy drinks with large amounts of caffeine may also have a diuretic effect. Most caffeinated beverages like coffee and tea don't appear to have much of a diuretic effect. Lost fluids must be replaced by the fluids in the foods you eat and the beverages you drink.
If you don't get enough water, you may suffer from hydration. Symptoms of mild dehydration include chronic painsin joints and muscles, lower back pain, headaches and constipation. A strong odor to your urine, along with a yellow or amber color, may indicate that you may not be getting enough water. Note that riboflavin, a B vitamin, will make your urine bright yellow when you take dietary supplements that contain large amounts of riboflavin. Certain medications can change the color of urine as well. Thirstis an obvious sign of dehydration, and in fact, you need water before you feel thirsty.
Some experts believe you can estimate the amount of water you need by taking your weight in pounds and dividing that number in half. That gives you the number of ounces you may want to drink each day. For example, if you weigh 160 pounds, you might want to drink at least 80 ounces of water or other fluids perday. Other factors include amount of physical activity and the climate where you are located. My water calculator can help you determine how much water you need to drink each day.
At least twenty percent of the water you need comes from the foods you eat. The rest comes from the beverages you drink. Water is probably the best choice because it's cheap and has no calories or added ingredients....
