Sweat glands are formed from the epidermis but project deep into the dermis. They occur over most of the body surface in humans and other higher primates but have a more limited distribution in other mammals. Dogs, for example, have very few sweat glands, and those mostly on the pads of the feet.
Sweat evaporates most rapidly when the outside air is warm and dry, and when it is windy. Excessive sweating must be compensated for by increased intake of water and salt. Swaeting may also increase in response to anxiety or stress.
