What happens when body temperature is too high?

When you are too hot you sweat so it evaporates from the skin to cool you down. Also in hot conditions, blood vessels in the skin dilate, allowing more blood to flow through the skin capillaries. This means that more heat is lost from the surface of the skin by radiation. This is called vasodilation
