What should you know about sweaty feet hands and armpits?

The soles, palms, and armpits contain many sweat glands, so they may become noticeably damp during heat, exercise, nervousness, or social situations. When sweating is frequent in comfortable conditions and affects more than one area, clinicians may consider hyperhidrosis. They may also review medicines and ask about thyroid symptoms, infection, glucose problems, or night sweats. Wet feet can become irritated and may develop peeling or fungal infection such as Athlete's Foot.

See [Excessive Sweating](/symptoms/excessive-sweating/) for language that can help you describe the pattern.

Record when each area sweats and whether heat, stress, food, or activity changes it. Keep feet dry, change damp socks, and use breathable shoes; gently dry the hands and choose clothing that allows air circulation. A clinician can check the skin and review possible triggers. Depending on the areas involved, options may include [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/) or [Iontophoresis](/treatments/laser-and-energy/iontophoresis/), which is commonly used for hands and feet.

Arrange a visit when sweating is new, steadily worsening, occurs at rest, or interferes with daily activities. Seek urgent help for heavy sweating with chest pain, fainting, breathing difficulty, confusion, or severe weakness. Contact a clinician promptly for fever, unexplained weight change, persistent night sweats, or a painful and infected-looking foot rash.

Does the distribution fit hyperhidrosis or suggest another cause? Should my medicines or general health be reviewed? Which treatment can address my hands and feet, and what can safely be used for my armpits?
