What is the process of becoming thirsty?

Answer 1

Thirst is the net result of water depletion, usually from hyperactivity. When we become active, our bodies withdraw water from non-essential sources to conserve it for vital needs, such as blood and organ function. The mouth and esophogus can go without water for some time.

In addition to activity, viruses and bacterium which use water for their own purposes can cause thirst. Alcohol intake and salts effect thirst as well. Anxiety can also be another cause of thirst, as you body in hypersensitivity will enact the same precautions as when it is in hyperactivity.

The key to controling thirst is to adequately hydrate yourself before you actually get thirsty.

Answer 2

When your body experiences a decrease in hydration levels, such as from sweating, urination, or not drinking enough fluids, your brain signals the sensation of thirst. This triggers you to seek out and consume fluids to rehydrate your body and maintain its proper function.
