Your body usually lets you know. On the norm it's 8 - 8 ounce glasses of water a day, but when training you are perspiring more so you could up to 10 - 12 glasses a day and that would be enough. Gatorade or other drinks such as this is also good to replace salt loss while perspiring.
The human body is 75% water. We need water for energy, detoxification, fighting dehydration and overall well being. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells and provides a moist environment for ear, nose and throat tissues.
The RDA is 2 liters of water per day, but this includes the water in the food that you eat. The water in food is significant: for instance, apples are 85% water.
Opinions from contributors include drinking 2 to 3 litres (33.8 ounces per litre) a day, or 8 to 12 glasses of water a day, depending on your size, physical activity, and overall health. It also can increase in hot, dry climates.
A good rule is to divide your weight (in pounds) by two to determine your water needs (in ounces per day). For example, if you weigh 150 pounds you should consume at least 75 ounces of water per day.
An easy way to know if you're drinking enough is to look at your urine. Urine should be a pale light yellow color. If the color is dark yellow the odds are you're dehydrated and should drink more.
