Answer:
Heat by constricting the blood vessels in the skin
Explanation:
The body responds to cold by constricting the blood vessels in the skin in order to reduce heat loss. However in the event where the body is overheating, the opposite occurs.
When the body is getting too hot, the blood vessels in the skin actually dilate. This means that the blood vessels get bigger, exposing the blood to colder temperatures to cool the body down (this may be why the skin may seem red after exercising or while it is very hot). Other mechanisms such as sweating also help cool down the body. When sweat is on the skin, evaporation occurs and cools down the sweat droplet, making sure the skin in contact with that droplet also cools down.
