What is thermoregulation ?

Mammals regulate their body temperature carefully and independently of their environment through a process called thermoregulation. A method of maintaining a constant internal temperature necessary for survival is temperature regulation.

• Poikilothermy and homeothermy are the two main reactions to changing environmental temperatures (TA) that animals display.

• Progesterone tends to promote heat conservation and higher body temperatures, whilst estradiol tends to increase heat dissipation, and both hormones have an impact on thermoregulation both centrally and peripherally.
