For all of those people constantly telling me I have to drink 8 glasses of water…
In general, to remain healthy we need to take in enough water to
replace the amount we lose daily through excretion, perspiration, and
other bodily functions, but that amount can vary widely from person to
person, based upon a variety of factors such as age, physical
condition, activity level, and climate. The “8-10 glasses of water per
day” is a rule of thumb, not an absolute minimum, and not of all of our
water intake need come in the form of drinking water.
The origins of the 8-10 glasses per day figure remain elusive.
