How to Fix Sweaty Palms

Longstanding sweating of both palms can be primary excessive sweating, in which nerve signals activate the sweat glands more than needed. Warm rooms, exercise, anxiety and handling certain materials may bring it out, but the symptom can occur without an obvious trigger. New sweating may instead relate to medicines or a health problem, especially if it is widespread or occurs during sleep.

Palm sweating can affect handwriting, phones, tools, sport and social contact. Moisture also makes irritated skin more vulnerable to cracking, so the goal is both to reduce sweat and to maintain the skin barrier.

Start by recording when sweating happens and review medicines with a clinician rather than stopping one yourself. Keep hands cool and dry, carry absorbent tissues, and use a suitable antiperspirant only as directed on intact skin. If these measures do not control the problem, a dermatology clinician may discuss iontophoresis, botulinum toxin injections or another targeted procedure. Each option has different schedules, sensations, aftercare and possible side effects.

Make an appointment if sweaty palms limit daily tasks, have persisted despite self-care, or are accompanied by sweating elsewhere, tremor, racing heartbeat, thirst, fever or unintentional weight change. Get urgent help for sudden heavy sweating with chest discomfort, fainting, confusion, severe weakness or difficulty breathing. A symptom that affects safety or signals overheating needs prompt evaluation.

Ask what cause is most consistent with your timeline, whether an examination or tests are needed, which first treatment suits your lifestyle, and how to manage dryness or irritation. Ask when improvement should be reviewed and what would warrant changing the plan.
