How does the body protect it self from extreme temperatures?

The body protects itself from extreme temperatures through various physiological mechanisms. In response to heat, it activates sweat glands to promote evaporative cooling and increases blood flow to the skin to dissipate heat. Conversely, in cold conditions, the body conserves heat by constricting blood vessels and generating heat through shivering. Additionally, behavioral responses, such as seeking shade or wearing appropriate clothing, also play a crucial role in temperature regulation.
