The skin's job is to protect the inside of the body from the outside world.
It acts as a preventive barrier against intruders that cause
infection, chemicals, or ultraviolet light from invading or damaging the body. It also plays an important role in the body's temperature
control. One way that the body cools itself is by sweating, and allowing that
sweat or perspiration to evaporate. Sweat is manufactured in sweat glands that
line the entire body (except for a few small spots like fingernails, toenails, and
the ear canal).
Sweat glands are located in the dermis or deep layer of the skin, and are
regulated by the temperature control centers in the brain. Sweat from the
gland gets to the surface of the skin by a duct.
A heat rash occurs when sweat ducts become clogged and the sweat can't get to
the surface of the skin. Instead, it becomes trapped beneath the skin's surface
causing a mild inflammation or rash.
Heat rash is also called prickly heat or miliaria.

Although a fever could be considered any body temperature above the normal 98.6 F (37 C), medically, a person is not considered to have a significant fever until the temperature is above 100.4 F (38.0 C)."...
