The purpose of sweat is to cool the body by sitting on the surface of the and allowing heat to escape from the body. Effective sweating is when someone is glistening as the moisture forms a cooling film over the skin. An abnormal lack of sweat in response to heat may be harmful, because sweating allows heat to be released from the body.
Anhidrosis is a medical condition where the body doesn’t have the ability to produce sweat or not having the ability to perspire in response to heat. This condition may go on unnoticed and the recognition will only take place when a considerable amount of effort, exertion or heat fails the body to cause sweating.
Anhidrosis can be difficult to diagnose. Mild anhidrosis often goes unrecognized, and dozens of factors can cause the condition, including skin trauma and certain and medications. Treatment of anhidrosis involves addressing the underlying cause, though in some cases, the reason for anhidrosis is never found.
What causes decreased sweating?
- Neurological causes: Head injuries, heat stroke, hysteria, and neurosurgical problems such as Guillain-Barre syndrome.
- that block sweat glands such as miliaria, dermatitis.
- Congenital absence of sweat glands which is hereditary.
- Some drugs (antipsychotic drugs used to treat mental disorders) or topical antiperspirants containing aluminum sulfate. Anticholinergics, such as atropine and scopolamine, can cause generalized anhidrosis.
- Trauma to sweat glands such as exfoliative dermatitis.
- Dehydration or heatstroke.
- New born and premature infants commonly show temporary anhidrosis for several weeks probably due to immaturity of neural supply.
Signs and symptoms include:
- Little or no perspiration
- or weakness
- Heart palpitations
- In the most severe cases, hallucinations, coma or death
