Imagine meeting someone for the first time and immediately feeling self-conscious about your wet handshake. You’re calm, the weather’s fine, but your hands won’t stop sweating.
That’s daily life for those living with palmar hyperhidrosis, a medical condition that causes excessive, uncontrollable sweating of the hands. It's a type of focal hyperhidrosis, where sweat is concentrated in specific areas. Most often, it’s caused by overactive sweat glands triggered by genetics, stress, or both.
Hand sweating disrupts even the most basic activities:
-
Using your smartphone: The screen gets a life of its own thanks to sweat.
-
Writing: Exams, forms, or heartfelt notes turn into smudged messes.
-
Eating with your hands: Think sticky fingers and melted chocolate.
-
Holding objects: Even a simple glass of water can slip.
-
Driving or using tools: Essential tasks become challenging or even risky.
While some people rely on quick fixes like wearing gloves or carrying tissues, these are just temporary solutions. The good news is that palmar hyperhidrosis is treatable.
Many begin with over-the-counter antiperspirants, including clinical-strength options. These can help reduce sweating for some. If they don’t, dermatologists may recommend prescription-strength topical treatments. These can be effective but may cause irritation, depending on your skin and the product. It’s best to consult a specialist to find what works for you.
Iontophoresis: A Long-term Solution
A commonly recommended treatment for palmar hyperhidrosis is tap water iontophoresis. It’s non-invasive, drug-free, and doesn’t involve needles. Best of all, it offers long-lasting dryness.
During treatment, you place your hands in trays filled with tap water while a device sends a mild current through the water and into your skin. This helps neutralize the sweat glands, temporarily stopping sweat production.
With a success rate of over 90%, iontophoresis has been used to treat excessive sweating since the 1940s. Today, it’s more accessible than ever, and can even be done at home.
