Our body temperature must stay at 37 degrees for our enzymes to work properly and even the slightest change in temperature can have massive effects. 

There are many reasons why our temperature may change eg.

  • heat produced when exercising 
  • fevers caused by disease 
  • external temperature rising or falling.

The control of our internal temperature relies on the thermoregulatory centre in the brain. It contains receptors which are sensitive to temperature changes. They monitor the temperature of the blood flowing through the brain. 

Extra information comes from the temperature receptors in your skin. These send impulses to the thermoregulatory centre giving information about the skin's temperature. It's very sensitive and can detect a difference of as little as 0.5 degrees.
