Sweating is one of the body’s most natural mechanisms—a biological air conditioner of sorts. Yet, when perspiration becomes excessive, it can disrupt comfort and confidence. Whether triggered by stress, heat, or an underlying condition, managing excessive sweating (also known as hyperhidrosis) requires more than just a swipe of deodorant.
We spoke to dermatologists and wellness experts to break down why it happens and what you can do to keep it under control.
Why do some people sweat more than others?
“Sweating is essential to regulate body temperature,” says Dr. Ananya Mehra, a dermatologist specializing in skin health. “But excessive sweating goes beyond physical exertion or warm weather—it’s often tied to overactive sweat glands or conditions like anxiety, hormonal imbalances, or even genetics.”
Primary hyperhidrosis (sweating without an underlying cause) commonly affects the palms, soles, and underarms. In contrast, secondary hyperhidrosis could be a result of medications or medical issues like diabetes or thyroid disorders.
Smart daily habits to help control sweat
1. Choose the right fabrics
Opt for natural, breathable fabrics like cotton, bamboo, and linen, which allow air to circulate and moisture to evaporate quickly. Avoid synthetic materials that trap heat and exacerbate sweat.
2. Reassess your skincare routine
“Using antibacterial body washes can help reduce odor-causing bacteria that thrive in moist environments,” says Dr. Mehra. Also, applying antiperspirants at night gives the active ingredients time to block sweat ducts effectively.
3. Hydration matters
While it may seem counterintuitive, staying hydrated can help regulate body temperature, reducing the need to sweat excessively. Infuse your water with cooling ingredients like mint or cucumber for added benefit.
4. Watch your diet
Spicy foods, caffeine, and alcohol can stimulate sweat glands. Cutting back on these triggers may help reduce flare-ups.
In-office treatments and medical options
For those whose sweating interferes with daily life, several professional treatments are available:
- Prescription-strength antiperspirants: Stronger formulations that can be more effective than over-the-counter products.
- Botox injections: Commonly used in underarms, palms, and soles, Botox temporarily blocks the nerves responsible for activating sweat glands. Results can last up to six months.
- Iontophoresis: A non-invasive treatment involving mild electrical currents passed through water to reduce sweating in hands and feet.
- Microwave therapy (miraDry): This procedure permanently targets and destroys sweat glands in specific areas like underarms.
The mind-body connection
Stress and anxiety can directly trigger sweat production. Incorporating relaxation techniques like yoga, meditation, or breathwork into your routine can help calm the sympathetic nervous system, which controls sweating.
“Think of managing excessive sweating as a holistic process,” advises wellness coach Priya Arora. “It’s about balancing external treatments with internal well-being.”
Final thoughts
Excessive sweating may feel uncomfortable, but it’s entirely manageable with the right approach. From mindful skincare swaps to professional interventions, a personalized plan can keep you feeling fresh—and confident—all year round.
