What is Hypohidrosis?

It sounds like hyperhidrosis, but it’s actually the opposite. Instead your body over producing sweat, if you have hypohidrosis it means your body is less effective at cooling itself down because you either sweat less or don’t sweat at all. We are going to talk about some of the symptoms, risks, and treatment of hypohidrosis.

It’s usually noticeable during really hot weather or during exercise, because your body has a harder time cooling itself down.


Some of the symptoms of hyperhidrosis include  

  • very dry skin
  • skin flushing
  • inability to tolerate heat
  • inability to tolerate physical exertion
  • feeling excessively hot
  • labored breathing
  • lightheadedness
  • muscle cramps or weakness

What causes hypohidrosis?

Hypohidrosis occurs because of poorly functioning sweat glands. Usually, as your body temperature rises, the autonomic nervous system stimulates the sweat glands which then release moisture onto the skin’s surface. The evaporation of the sweat cools the skin (you can read more about this in our blog about sweat).

There’s a bunch of reasons why someone might have hypohidrosis. It came range from a skin condition or injury (like a burn) to a symptom of an immune of neurological condition. Sometimes, people have idiopathic hypohidrosis, which is hypohidrosis that occurs with no known cause.

One of the major risks of hypohidrosis is the risk of heat stroke. Symptoms of heat stroke include:

  • intense thirst
  • a headache
  • dizziness and confusion
  • fast breathing or rapid pulse
  • fever
  • nausea and loss of appetite
  • cramps in the arms, legs, and stomach

Heat stroke is a serious medical condition and if you think you might be experiencing any of those symptoms, contact emergency services immediately.


How you treat hypohirosis really depends on the underlying cause. If the cause is due to another medical condition, hypohidrosis may improve once a person begins treatment for that condition.

Below are some tips on how to keep the core body temperature within safe limits:

  • taking regular cool showers
  • using a cool mist humidifier indoors
  • wearing loose-fitting clothing
  • wearing damp clothing in hot weather
  • applying damp flannels to the skin
  • avoiding over-exertion, particularly in hot weather
