How your Body Regulates Temperature


  1. Perspiration/Evaporation
  • The brain knows when to start sweating because of the hypothalamus.
  • The hypothalamus helps the body maintain homeostasis in the body, which from a temperature standpoint means that the hypothalamus helps regulate the body temp at 98.6°F.
  • The hypothalamus regulates the temperature of the body by ensuring that the heat the body generates is equal to the heat lost by the body.
  • When the hypothalamus senses that the body is too hot, it sends signals to the sweat glands to make the body sweat.
  • Perspiration or sweating is the process in which a large number of glands under the surface of the skin throughout the entire body begin to secrete moisture.
  • On hot days, sweat evaporates from the skin, taking a little of the body heat with it.
  • In order to feel the benefits, the sweat must evaporate off the skin.


  1. Radiation Cooling
  • Radiation Cooling occurs when the body gives off heat to surrounding objects and the environment. This is the body’s primary method of cooling when it is at rest.  The skin is always radiating heat in all directions to objects near it.


  1. Conduction
  • Conduction is the process of losing heat through physical contact with another object or body. If you sit on something cold, the heat in your body will leave you and transfer to the object you are sitting on. Conduction occurs when using a Super Cool Cooling Vest. The Super Cool Cooling Vest is charged at 58°F so when it is worn, the heat is transferred to the vest and cools the body.


  1. Convection Cooling
  • Convection cooling is the process of losing heat through the movement of air or water molecules across the skin.  A fan blowing onto the skin or water on the skin are examples of convection cooling.
