Sweating FAQs

Learn more about perspiration

No one’s immune to the odd wet patch, especially when the temperatures start to rise. So let’s talk about sweating: the ways it can support our health, and what to do if you do it too much.


What can I do about ‘nervous sweating’?

When we sweat, it’s usually a physical response from our bodies trying to cool down and regulate our temperature. But strong emotions such as excitement, anger or fear can also trigger the sympathetic nervous system, causing us to sweat. If you find that you get ‘nervous sweat’ before a big meeting, try an anti-perspirant that’s long-lasting, such as the Dove Maximum Protection range. The key is applying it the night before - as we usually perspire less when we’re sleeping, sweat glands can absorb the compound more easily, helping block perspiration. Sounds weird, but it works!


Why do my feet smell?

Each foot has 250,000 sweat glands, which can produce up to half a pint of sweat a day! And after being inside a shoe, with natural foot bacteria and fungi, feet are likely to get a bit smelly. Odor-Eaters Sport Foot & Shoe Spray can help tackle it.


What is extreme sweating?

Also known as hyperhidrosis, this is when people sweat excessively even when their body doesn’t need to cool down. There’s not always a clear reason as to why it happens and standard deodorants won’t deliver, so speak to a member of our pharmacy team who can advise on suitable options for you. You can also speak to a pharmacist about your excessive sweating if you have concerns. It can be helpful to try wearing loose-fitting clothes and socks that absorb moisture. If you’ve tried these options and are still experiencing excessive sweating, speak to your GP.


Why do we sweat during exercise?

Exercise causes your body temperature to rise, so sweating is a way of regulating it and cooling you down. And if you’re working out when it’s hot, you can lose one to six pints of perspiration per hour! To help prevent dehydration, pack a BRITA Fill & Go Active Water Bottle in your gym bag, so you can hydrate on the move.


How else does sweat help?

Aside from cooling you down and regulating body temperature, it can also do these three things:

• It fights germs. Sweat glands secrete an antibacterial and antifungal peptide called dermcidin, which can help fend off harmful bacteria such as Staphylococcus aureus (which can lead to abscesses)

• It heals wounds. Not technically sweat, but your sweat glands store a supply of clever stem cells that help heal wounds

• It makes you happier. OK, wet patches won’t exactly have you laughing out loud, but there’s good evidence that getting a sweat on during exercise can help improve your mood
