How the Body Regulates Temperature

The hypothalamus is very sensitive to temperature changes. It starts cooling down or warming up the body as needed. “When the body’s temperature rises, the hypothalamus makes you sweat to cool down,” it explains the balance in temperature regulation. On the other hand, if it’s too cold, it makes you shiver to warm up.
