Sweating - absent

An abnormal lack of sweat in response to heat may be harmful, because sweating allows heat to be released from the body.

Anhidrosis sometimes goes unrecognized until a substantial amount of heat or exertion fails to cause sweating.

Overall lack of sweating can be life-threatening because the body will overheat. If the lack of sweating is localized (happening in a small area only), it is usually not as dangerous.
