Sweaty Palms: When It Is Normal and When to See a Doctor

In short: damp palms from nerves, heat or exertion are normal. If sweat is noticeably heavier than needed for cooling, interferes with daily life and lasts for months, it may be hyperhidrosis (excessive sweating), which is worth discussing with a doctor. Both home measures and medical treatment that a doctor prescribes can help.

Why palms sweat

The sweat glands on the palms respond not only to heat but to emotion: nerves, stress and tension (for example during competitive play) can increase sweating. This is a normal reaction of the nervous system.

Normal or hyperhidrosis

Normal sweating. Sweat rises in response to heat, exertion and nerves, and passes when the cause goes.

Hyperhidrosis is a condition where more sweat is produced than needed for cooling. According to the NHS, see a doctor if excessive sweating:

• is not improving with home measures;
• has lasted at least 6 months;
• stops you getting on with daily activities;
• happens at least once a week;
• happens at night (night sweats);
• runs in the family;
• occurs while you are taking medicine for another condition.

NHS: excessive sweating.

Sweating also occurs as a symptom of other conditions (for example thyroid problems, diabetes, infections or medicines), so the cause should be determined by a doctor.

What you can do at home

• Antiperspirants. According to the NHS, you can buy antiperspirants stronger than ordinary deodorant at a pharmacy without a prescription; a doctor may prescribe an even stronger aluminium chloride product. They are best applied to clean dry skin, usually at night. NHS. More: hand antiperspirant cream.
• Wash and dry the hands well.
• Avoid triggers: overly hot rooms, spicy food, caffeine, if you notice a link.
• Breathing techniques and rest when stressed.
• Moisture-wicking clothing and rotating spare items, see gaming sleeve in summer and winter.
• Keep the work area dry: wipes, a clean pad, see sweat and the mouse.

What a doctor offers

According to the NHS description, a doctor may offer stronger antiperspirants, iontophoresis (a procedure using a weak current in water), medicines that reduce sweating, or other methods. The choice depends on the situation and should be prescribed by a specialist. Do not use medicines or procedures on your own without a consultation.

Which doctor

You can first see a family doctor or GP, who will refer you to a dermatologist or another specialist if needed.
