When the body is exposed to a cooler or warmer temperature than the normal bodily temperature, or set point temperature, the body works hard to get the internal temperature back into alignment. In regards to homeostasis and temperature regulation, the body uses negative feedback to bring its internal temperature back into a normal balance. Negative feedback is a homeostatic control mechanism that works in the opposite direction of the initial change to help regulate that change and bring certain variables, such as body temperature, back to normal levels.
