Sweat or perspiration is the body’s way to cool itself. We tend to sweat more when we are hot and less when are feeling cold. Most people see sweating as an uncomfortable and undesirable process but it is actually a life saving mechanism. Sweating excessively is one of the more commonly known abnormalities with perspiration. It is often a cause of great distress. On the other hand, sweating too little or even not at all especially in hot environments can be dangerous and even fatal.
What is anhidrosis?
Anhidrosis is the medical term for no sweating. This means that a person is unable to perspire as would be normally expected. A similar term is hypohidrosis. This means that the sweating is at very low levels as would be the norm for the situation. Disturbance in sweating in this way allows the body temperature to rise and eventually lead to heat-related illnesses. In hot environments, this can be fatal within hours or days. Anhidrosis is usually a consequence of some underlying problem or disease which needs to first be treated for sweating to be restored. Patients with certain causes of anhidrosis may never be able to sweat as normal and have to adapt their lifestyle to avoiding heat and keeping cool through artificial methods.
