How would the sweat glands react when the temperature gets really cold? What about the hair follicles in your skin?

Respuesta :

Your sweat glands would close.
The sweat glands would stop secreting sweat.
The hair erector muscles in the skin would contract causing the hairs on the skin to stand up (this may cause the appearance of goosebumps). The erect hairs trap a thin layer of air that acts as insulation against heat loss from the body to the environment.
