During a heat spike, the body triggers adaptation mechanisms such as sweat. When your body temperature exceeds 37°C, your body activates mechanisms to thermal regulation : he begins to sweat and breathing quickens. The heat is then eliminated via the water and the steam released. During this time, blood vessels on the surface of the skin increase in diameter (vasodilation) to cool the blood.

THE heart is also harmed. During a heat wave, the skin vessels dilate and the blood is distributed towards the extremities. The heart is then forced to pump more, thus increasing the heartbeat 10 to 15 beats per minute more, even at rest.
