Excessive sweating

First things first, it’s important to know that sweating is a natural response to an increase in temperature. If you get hot, your body releases sweat to help you cool down.

Sweating while you’re working out or even on the packed commuter train to work is one thing. But when there’s no natural trigger, it may be worth chatting to your doctor or dermatologist about it.

Don’t worry, though – excessive sweating is common, and there are various treatments that can help.

So, what causes excessive sweating?

There are two main causes:

Primary hyperhidrosis – a medical condition that causes overactive sweat glands. Although it affects all parts of the body, it’s often localised to specific areas like the palms of the hands, armpits, in the groin area or the back.

Secondary hyperhidrosis – this can be a side effect of medication, a change in hormone levels or a damaged nervous system.

Excessive sweating brought on by either of these are best dealt with by a doctor or dermatologist. They can recommend proper medical treatment.

Use extra protection antiperspirants like Rexona Clinical Protection, which has 3x sweat protection vs a normal antiperspirant. Game changer! 

Wear natural fibres like cotton, wool and silk as much as possible to stay cooler during the day.

Stay hydrated by drinking plenty of cool water. This helps lower your body temperature and replace some of the water lost through excessive sweating.

Avoid potential sweat triggers, like spicy food, caffeine, smoking and alcohol.

Wash regularly, particularly focusing on the areas you sweat the most.

If these don’t help, don’t worry. There are other approaches you can take. Speak to your doctor or dermatologist – they’ll be able to talk you through options such as medication and other specialised treatments.
