Truth be told. The body is about 60% water.
You are constantly losing water from your body, primarily via urine and sweat.
Here are tips on how useful water is to the human body.
1) To prevent dehydration, you need to drink adequate amounts of water.
There are many different opinions on how much water you should be drinking every day.
Health authorities commonly recommend eight 8 glasses, which equals about 2 liters, or half a gallon. This is called the 8×8 rule and is very easy to remember.
2) Some health gurus believe that you need to sip on water constantly throughout the day, even when you’re not thirsty.
As with most things, this depends on the individual. Many factors (both internal and external) ultimately affect your need for water.
