<em><u>Homeostasis</u></em>
Explanation:
One function of the hypothalamus is to <u>regulate body temperature</u> known as homeostasis. Hypothalamus <u>maintains the body temperature to a normal temperature of about 37°C.</u> When you step out without the jacket in cold, your body temperature fall to 37°C.
