Anhidrosis is the inability to sweat normally. When you don't perspire, your body can't cool itself, which can lead to overheating and sometimes to heatstroke — a potentially fatal condition.

Anhidrosis — sometimes called hypohidrosis — can be difficult to diagnose. Mild anhidrosis often goes unrecognized, and dozens of factors can cause the condition, including skin trauma and certain diseases and medications. You can inherit anhidrosis or develop it later in life.

Treatment of anhidrosis involves addressing the underlying cause, if one can be found.
