Understanding Hyperhidrosis - When sweating goes beyond normal — and what you can do about it.

What Is Hyperhidrosis?

Hyperhidrosis means “excessive sweating.”
It happens when the body’s sweat glands are overactive, producing more sweat than needed to cool you down.
It can affect the underarms, hands, feet, face, scalp, groin, or even the whole body.

There are two main types:

Primary (Focal) Hyperhidrosis Overactivity of sweat glands without another underlying medical cause. Often hereditary. Underarms, palms, soles, face

Secondary (Generalized) Hyperhidrosis Excessive sweating caused by another condition or medication. Whole body or trunk

Why It Happens

Sweating is controlled by your sympathetic nervous system.
In hyperhidrosis, the nerves signaling the sweat glands fire too frequently — even when your body doesn’t need to cool down.

Common triggers include:

  • Heat or humidity

  • Stress or anxiety

  • Spicy foods or caffeine

  • Hormonal shifts (thyroid, menopause, cycle)

  • Certain medications

  • Family history

How to Tell If It’s More Than “Normal” Sweat

You might have hyperhidrosis if you:

  • Sweat enough that clothing becomes wet through or slippery to the touch

  • Avoid shaking hands, holding devices, or wearing certain fabrics

  • Need to reapply deodorant several times daily

  • Experience emotional or social stress due to sweating

  • Have clammy hands or feet even at rest

If that sounds familiar, you’re not alone — it’s estimated that 1 in 20 people in the U.S. live with some form of hyperhidrosis.

How The SweatLab by Epis™ Helps

We don’t diagnose hyperhidrosis — we decode your sweat patterns so you can make informed next steps.

Through a 5-minute assessment, The SweatLab™:

  1. Classifies your Sweat Profile (e.g., Sulfuric-Reactive, Musty-Microbial, etc.)

  2. Identifies potential Biofilm or Endocrine Modifiers

  3. Provides a non-medical care report with:

    • Product & fabric recommendations

    • Environmental triggers

    • Suggested clinical options to discuss with your provider

Cosmetic & Lifestyle Measures

These do not “treat” hyperhidrosis but can help manage the symptoms and odor:

Topical / OTC Strategies

  • Clinical strength antiperspirants with Aluminum Zirconium Tetrachlorohydrex GLY

  • Buffered low-pH or glycine-stabilized formulations to reduce irritation

  • Alternating days of zinc- or magnesium-based deodorants to avoid tolerance

Clothing & Laundry

  • Wear breathable natural fibers: cotton, bamboo, linen

  • Avoid re-wearing synthetic athletic gear

  • Add borax or oxygen boosters to laundry to remove trapped odor compounds

Barrier Care

  • Use mild cleansers; over-washing worsens irritation

  • Apply niacinamide or ceramide moisturizers to support barrier recovery

Seek professional evaluation if:

  • Sweating is constant and unrelated to heat or activity

  • You experience night sweats or unintentional weight loss

  • It interferes with work, relationships, or mental health

  • OTC products have failed after consistent use

You can ask your dermatologist about:

  • Brella™, miraDry®, Botox®, or oral anticholinergics

  • Topical prescription options like glycopyrronium or sofpironium

Bring your SweatLab Report — it summarizes your triggers and profile type, making the consultation faster and more focused.

The SweatLab by Epis™ is not a diagnostic service and does not replace professional medical evaluation.
Our reports help you understand why your sweat behaves the way it does, so you can choose evidence-based next steps confidently.
