The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors.
When you suffer from heat intolerance, it is often because your body is not regulating its temperature properly. Your body regulates its temperature by maintaining a delicate balance between hot and cold. The hypothalamus is a part of the brain that regulates your bodyâs temperature. When you get too hot, your hypothalamus sends a signal through your nerves to your skin, telling it to increase sweat production. When sweat evaporates off of your skin, it cools your body down.
