  Water
is the major component of the human body. It is essential to
life.
The more muscular the body, the more water it contains, and—conversely—the
fatter the body, the less water it contains.
While water is indispensable for cells in the human body, it is
also necessary for blood, and the distribution of nutrients, vitamins,
and minerals to the cells. Water is everywhere; it is at the heart
of life.
Building
up your water reserves every day
Both adults and children lose significant amounts of water, through urination,
respiration, and perspiration, for example. It is important that children
learn and understand that this water needs to be replaced. How? Drinking
water regularly is the best way. This habit is vital to good health.
And simply by eating fruit and vegetables, made up of 90% water.
A child of 4 years or older should drink at least 1,2 l of water a day,
whereas adults at least 1,5 l.
These quantities should be increased in hot weather or during prolonged
exercise, as physical effort expends energy and generates heat. This
heat is generally lost through perspiration, in order to maintain a constant
body temperature.
