What is Excessive Sweating (Hyperhidrosis)?
Hyperhidrosis is excessive sweating beyond what's needed to regulate body temperature, most commonly affecting the underarms, palms, soles, or face. It can be a standalone condition (primary hyperhidrosis) or occur as a result of an underlying health condition or medication (secondary hyperhidrosis).
It can significantly affect confidence and daily life, but a range of effective treatments exist, from stronger antiperspirants to medical treatments like specific medications, Botox injections, or, for severe cases, surgery.

Clinical context

Practical steps
Apply Antiperspirant to Dry Skin at Night for Best Results
Antiperspirants work best when applied to completely dry skin at night, allowing time to work before washing off in the morning, rather than applying to already-sweaty skin during the day.
- 1Try a prescription-strength antiperspirant.Applied correctly to dry skin, often at night, this can be effective for many people.
- 2Wear breathable fabrics.Natural fibres like cotton can help manage sweating and reduce discomfort.
- 3Consider stress management techniques.Stress and anxiety can worsen sweating for some people, so relaxation techniques may help.
- 4See a doctor if over-the-counter options aren't enough.Further treatments, including specific medications or Botox injections, are available and effective for many people.
- 5Ask about the cause if sweating started suddenly.This can help identify if an underlying condition needs addressing.
