Hypohidrosis is diminished sweating in response to appropriate stimuli. While hyperhidrosis is a socially troubling but benign condition, hypohidrosis can lead to hyperthermia, heat exhaustion, heat stroke and potentially death.
Anhidrosis, sometimes referred to as hypohidrosis, sudomotor dysfunction or sweating dysfunction, is an abnormal lack of sweat in response to heat - the person's body is unable to sweat normally.
Anhidrosis is the complete absence of sweating, while hypohidrosis is sweating less than normal.
If the human body cannot sweat properly it cannot cool itself, which is potentially harmful. Sweating allows heat to be released from the body.
If the lack of sweating affects a small area of the body, it is not usually dangerous. However, overall anhidrosis or hypohidrosis can result in overheating and eventually heatstroke, a potentially life-threatening condition.
Sweating is your body’s way of cooling itself off. Some people are not able to sweat normally because their sweat glands are no longer functioning properly. This condition is known as hypohidrosis or anhidrosis. It can affect a person’s entire body, a single area, or scattered areas.
The inability to sweat normally can cause overheating, which can lead to heat stroke a potentially fatal condition.
Hypohidrosis can be difficult to diagnose; mild hypohidrosis often goes unnoticed. The condition has many causes. It can be inherited or develop later in life.
Eccrine gland sweating is the principal means of thermoregulatory heat dissipation in humans.
