Answer: Dear Brenda,
Depending on the temperature of
where you are at a specific moment, the body might not have the need
to sweat to cool-down. The human body works best when its temperature
is about 98.6º Fahrenheit (37º Celsius). If you never sweat
at all, it could be because the temperature outside is cool or not
hot enough to make your body sweat. It can depend on where you live
or what kind of activity you are doing.
However, an abnormal lack of sweat in response to heat may be harmful,
because sweating allows heat to be released from the body. Decreased
sweating is called Anhidrosis. If a substantial amount of heat fails
to cause sweating then Anhidrosis may be present.
