Excessive sweating, medically known as hyperhidrosis, can affect the armpits, hands, feet, face, scalp or other areas of the body.
It can be uncomfortable, embarrassing and surprisingly disruptive.
Fortunately, there are several treatments available, including conventional topical products and some traditional herbal remedies.
Start With Antiperspirants
There's an important difference between deodorants and antiperspirants. Deodorants primarily tackle odour, while antiperspirants actually reduce the amount of sweat reaching the skin.
Products containing aluminium salts, particularly aluminium chloride, are commonly used for excessive sweating. Stronger preparations are available from pharmacies and may be recommended by a GP.
They are usually applied to completely dry skin at night and washed off in the morning. Following the instructions carefully is important because stronger antiperspirants can cause skin irritation.
What About Sage?
Sage (Salvia officinalis) has a long history of traditional use for excessive perspiration, including sweating associated with the menopause.
Sage is available as tea, tablets, tinctures and other preparations. However, while there is some research into sage for menopausal symptoms such as hot flushes and sweating, evidence for treating hyperhidrosis itself is limited.
Herbal doesn't automatically mean harmless, either. Concentrated sage products can contain thujone, which may be harmful in excessive quantities. Anyone taking medicines, pregnant or breastfeeding, or living with a medical condition should check with a pharmacist or doctor before using herbal supplements.
Witch Hazel
Witch hazel is an astringent and is sometimes suggested as a topical treatment for sweaty skin. Applied to areas such as the feet or underarms, it may make the skin feel temporarily drier.
However, evidence that witch hazel actually treats hyperhidrosis is lacking, and frequent application can irritate sensitive skin. It should therefore be regarded as a possible comfort measure rather than a proven treatment.
Other Traditional Remedies
People sometimes recommend cooled black tea soaks for sweaty hands or feet because tea contains tannins with astringent properties. Again, scientific evidence for treating hyperhidrosis this way is limited.
Whatever remedy you try, avoid applying potentially irritating substances such as neat essential oils or strong acidic preparations to sensitive, broken or freshly shaved skin.
When Sweating Deserves a GP Appointment
Excessive sweating isn't always simply a nuisance. Sometimes it can be associated with another condition or with medication.
It's particularly worth seeking medical advice if excessive sweating starts suddenly, occurs predominantly at night, affects your whole body, is accompanied by unexplained weight loss, fever, palpitations or other symptoms, or represents a significant change from your normal pattern.
A GP may investigate possible underlying causes and discuss treatments ranging from prescription-strength antiperspirants and tablets to iontophoresis, botulinum toxin injections and specialist procedures.
The important message is that you don't necessarily have to put up with excessive sweating. Herbal and traditional remedies may provide some people with modest relief, but persistent or severe hyperhidrosis deserves proper assessment — and there are effective medical treatments available.
