human musclesNutrition: Water  is possibly the most important macronutrient in the diet. The body is made up of about 70% water and water is essential for life. Water is lost not only through perspiration and urination but also through respiration. This water must be continually replaced to maintain optimum hydration. Dehydration can not only decrease performance but, in serious cases can result in serious side effects or even death.  Often, by the time one is thirsty, dehydration has already set in. When exercising strenuously, it is important to periodically rehydrate even if you are not thirsty. It is recommended for those who exercise regularly to take in one half to one gallon of water per day depending on body size. Of course, as with most things, people take things to excess and assume that if some is good for you, then more must be better. Some have recommended consuming 2 or even 3 gallons of water per day. At these quantities, water can act as a diuretic. It is important to note that taking in large quantities of water can result in a condition known as water intoxication that can result in coma or death due to dilution of the body’s electrolytes.
