It is a physiological need that must be satisfied in order to maintain health. THIRST is also a psychological need, as it can be triggered by emotions such as stress or boredom. In addition, it can be caused by certain medications or medical conditions. THIRST is an important part of maintaining a healthy lifestyle, and should not be ignored.
