Most people perspire in Singapore’s heat, but some suffer from a level that is embarrassingly excess compared to others. The condition of excessive sweating begins when the person is below the age of 30. Excessive sweating is a common ailment and can affect several parts of the body. Our palms and soles have the highest density of sweat glands, followed by the scalp, underarms and groin.

Excessive sweating may be caused and aggravated by a combination of genetics and situational, lifestyle and medical factors:

  • Family history of primary hyperhidrosis
  • Gender (males are 20% more likely to develop primary hyperhidrosis of palms and soles, while females are more likely to develop primary hyperhidrosis of underarms. Menopause also increases the risk of late-onset hyperhidrosis in women)
  • Anxiety
  • Physical activity
  • Infection
  • Heat and humidity (environmental conditions, synthetic garment materials)
  • Oral medication (such as antidepressants)
  • Catabolic states (overactive thyroid, malignancies)

Excessive sweat can also cause a number of problems, besides the embarrassment to the patient.

  • Individuals with skin problems (such as eczema) may experience sweat-aggravated flare ups of eczema at the underarms, hands or feet.
  • Sweaty palms and soles also predispose people to viral warts or pits in the soles due to bacterial infection.
  • Excessive sweating in the underarms is often accompanied by an unpleasant odour and the wet patches limit a person’s choice of clothing.
  • Sweaty feet are associated with foot odour due to bacterial action on sweat and dead skin; cold, clammy hands.

If the condition bothers you, consult a dermatologist, who will be able to help you. Main treatment options include topical medications, iontophoresis, non-to-minimally invasive procedures (such as botulinum toxin injections and miraDry™ microwave destruction of sweat glands in the underarms) and surgery (sympathectomy, excision of sweat glands).


  • Apply antiperspirant at bedtime and re-apply in the morning if needed
  • Use antibacterial (deodorant, antibacterial shoe powder, antibacterial wash) to eliminate odour
  • Use ballpoint pens to avoid smudging
  • Wipe hands on sides of trousers or skirt before shaking hands
  • Adopt postures that allow airing of underarms
  • Wear clothes made from natural absorbent materials such as cotton, bamboo and linen, as well as open-toe sandals or shoes made from canvas or leather (rather than synthetic or rubberised materials that obstruct evaporation of sweat)
  • Stay in an airconditioned environment where possible. In cold climates, wear a sleeveless vest instead of layering long-sleeved tops to avoid overheating
