Why drink water during exercise?
Show answer & explanation
Answer: It replaces water that the body loses in sweat
It replaces water that the body loses in sweat ✓ — Drinking replaces water lost in sweat and helps maintain circulation and heat regulation. Needs vary with conditions and sweat loss, and drinking excessive amounts can dangerously dilute blood sodium.
It cools the body mainly by sitting in the stomach — Water sitting in the stomach is not the main cooling mechanism during exercise. Much of the cooling comes from sweat evaporating from the skin, and drinking helps replace the water lost.
It washes sweat directly through the kidneys — Drinking does not send sweat through the kidneys. Sweat leaves through the skin; kidneys separately regulate water and remove waste in urine.
