International Hyperhidrosis Society


Hyperhidrosis is an idiopathic disorder of extreme, uncontrollable, episodic, and/or unexpected sweating beyond what’s “normal” or necessary to regulate temperature or as a reaction to stress.

Primary Hyperhidrosis (Hh)

Hyperhidrosis = 4 or 5 times more sweat than “normal”\
~365 million people worldwide affected
4.8% of the general population; 8.8% of those aged 18-39

Childhood/Adolescent Onset | Bilateral | Ceases when Sleeping | Familial

Hyperhidrosis is Not Rare or Benign

But it is often misunderstood, over-simplified, under-diagnosed & under-treated.
You can help Hh patients to be heard, to find relief, and to live a life that’s not dominated by their sweating. It starts with recognition. The facts are:

  • Hh is more common than Autism, Melanoma, Psoriasis, and Peanut
  • Hh has quality of life impacts equal to or greater than those of: Psoriasis, Severe acne, Darier’s disease, Hailey-Hailey disease, Vitiligo, & Chronic

Mental Health Impacts

With Hyperhidrosis:           Depression 27%         Anxiety 21%
Without Hyperhidrosis:
    Depression 10%         Anxiety 7.5%

5% of Hh sufferers say they take antidepressants or anti-anxiety medications due to their sweating.

Relationship Impacts

Most Hh sufferers avoid public view, handshakes and other forms of touch.
75% of those with excessive sweating say the condition has had negative impacts on their social life.

Physical Health Impacts

300% greater risk of skin infections among Hh sufferers 60% report negative impacts on general health
40% report physical discomfort

Daily Life Impacts

Needing to change clothes frequently Damaging paperwork
Impaired dexterity Slips and falls
Difficulty gripping tools, playing musical instruments, and using electronic devices
80% of Hh sufferers dissatisfied with their abilities at work

It’s important to address Hh with patients in a timely fashion as, research shows, the severity of Hh does NOT lessen with age and the negative impacts are many (and arguably cumulative).
