Would you drink hydrogendioxide? I really hope your answer is yes, because it's water! Water plays several roles in our body. Without it we wouldn't survive for more than 3 to 5 days. After all, we are made up of about 70% water. Learn about the four major roles of this important chemical.
Have you ever noticed how water has a way of keeping cool in a pool in the hot summer and that it's warmer by the lake in the winter? This phenomenon happens because water has a high specific heat, meaning it takes a relatively large amount of energy to change the temperature of water. That's why it's so good at keeping us at the preferred setting of 98.6 F. Water keeps us from getting overheated when we are in hot climates, exercising, and even from the hard work of metabolizing food (who knew that breaking down carbs, fats and proteins made so much heat?)
The ultimate transporter
Water makes up a large majority of your blood, saliva, and GI secretions (you know, the lining of your intestines and stuff). What's it doing there? Helping move vitamins and minerals to the cells where they need to go and flushing out the icky, toxic wastes.
Smooth as a whistle
Water keeps stuff moist-- your GI tract, lungs, skin, and sex organs. This is important because it works as a protective shield against irritants, pathogens and protects those ever-so-delicate tissues.
Turning the food that you eat into usable energy requires some extra help from our pal water. When water is added to compounds like triglycerides (fat) and carbohydrates, they get split up into smaller, more manageable compounds so that energy can be made. Cool, right?
To keep this all working smoothly, remember to get your 11 cups of water a day for women, and 16 cups for men. This includes the water that's already in your food-- so lets call that about 8 large glasses of water a day and you're good to go!
