Human skin, whose cells are generated continuously by the body, serves as a protective barrier between the inside of the human body and the environment.
When body temperature rises, the human body employs homeostasis to maintain a stable internal environment. The hypothalamus in the brain acts as the primary regulator of this process.1
In response to thermal stimulation, the sympathetic nervous system triggers the eccrine sweat glands to secrete water onto the surface of the skin. This secretion cools the body through evaporation, which is a critical mechanism for heat dissipation. While eccrine glands are distributed across the body, those located on hairy skin are specifically adapted to respond to thermal stimuli for the purpose of thermoregulation. In contrast, apocrine sweat glands are primarily associated with emotional stress rather than temperature control.23
