The sweat glands in the dermis work to help release a watery fluid known as sweat onto the skin. When sweat is released, it comes into contact with the skin and evaporates to help cool it down. Sweating is one of the easiest ways that skin is able to regulate the temperature of the body.

The dermis is the second layer of the skin and it is located underneath the protective epidermis layer. The dermis contains all of the main parts of the skin and works to produce everything that the skin needs. It is situated above a layer of fat which helps to trap heat and keep the body warm. The combination of fat and the dermis layer of the skin work to provide a sort of insulation for the body while giving it the protection that it needs from outside sources.
