A lot has been written about the health benefits of drinking water. It seems these days that more and more people carry bottled water everywhere they go. Each day we lose large amounts of water from sweating, breathing, urine and stool, and these water losses must be replaced daily to maintain a proper function of our body. When your water intake is below your water output, you can become dehydrated, and I’ve already written about what happens to your body when you are dehydrated.

General Fluid Intake Guidance
Everyone knows the advice of drinking eight 8-ounce glasses of water (or fluids) a day which is nearly 2 liters, but your needs really depend on several factors, such as your physical activity, your health, what you’ve eaten, your overall mass, your health, age, the climate you live in, so you will need to modify your water intake depending on these factors.
