The Story: Your Body's Thermostat

Imagine your body as a house with the most advanced thermostat ever invented. No matter if it's freezing outside or boiling hot, your house maintains exactly 20°C inside. But your body does even more than this — it controls temperature, water levels, blood sugar, and more, all at the same time! This automatic regulation system is called homeostasis.

Quick Recall Flashcards

What is thermoregulation?
Thermoregulation is the process of maintaining a constant core body temperature of 37°C, regardless of changes in the external environment.
How does sweating cool the body?
Sweat glands release sweat onto the skin. As sweat evaporates, it takes heat energy away from the skin, cooling the body. More sweating occurs when the body is too hot.
