The hypothalamus causes the body to react differently when the body is too hot or if the temperature gets too cold. <span>The normal body temperature is 37'. The hypothalamus triggers the receptors such as sweat glands and body hair muscles in the body.The sweat glands open up when the body is too hot and secrets sweat until the temperature is regulated again. Similarly in cold conditions the body hair muscles pull the hair upright because standing hair absorbs more heat until the falling body temperature returns to normal.</span>
