Up
to 60 percent of the human body is water, the brain is composed of 70 percent
water, and the lungs are nearly 90 percent water. About 83 percent of our
blood is water, which helps digest our food, transport waste, and control
body temperature.We lose more water than you’d think just by breathing.
The busier and more active we are, the more we need to drink to replace
the lost fluids.
So the guy who's always drinking water in your office might also be the
one who's the busiest! |
