Description: The body has over 3 million sweat glands that produce sweat. the sweating response to a rise in hypothalamic temperature is much larger than the response to the same increase in average skin temperature.

Emotionally induced sweating is generally restricted to palms, soles, and sometimes the forehead, while physical heat induced sweating occurs throughout the body.
