Which is the best way to avoid dehydration? avoid exercise when it is warm outside. avoid wearing helmets so that heat can escape. drink the amount of water lost in sweat. wear dark clothing so that sweat can evaporate.

Drink the amount of water lost in sweat.

Explanation:

Water is always essential for normal bodily functions, however water requirements typically increase in warmer weather or as the body temperature increases through exercise. The body uses its water to get rid of heat via homeostasis, a process where the body’s internal environment is strictly maintained.

Perspiration is a homeostatic mechanism in which the body exudes water onto the skin through sweat gland secretions. This reduces body heat as the sweat cools underlying tissues when evaporated. Adequate hydration during physical activity involves drinking the approximate amount of water used, which prevent dehydration in the body; additionally water along with electrolytes can more efficiently replace fluid lost through sweating.
