Feeling hot and sweaty? CNA Lifestyle asks your burning questions about all things related to sweat.
Why do some people sweat a lot? Does sweating help you detox? Why does it feel sticky after it's dried up?I don’t know about you but I can’t step outside without wearing my body’s very own brand of tears. My sweat glands are constantly weeping for the respite of a cool, heat-repelling climate that Singapore naturally lacks – then reminds me again with the stickiness of a thousand Post-It notes after the perspiration has dried off.
So, yes, we’re going to work up a sweat and ask the experts to address some questions and commonly held notions below:It depends on your level of activity and the environment you’re in. Typically, a healthy, average-sized person produces 500ml of sweat every hour when performing a low-intensity activity , said Dr Kok Wai Leong, a senior consultant and dermatologist at StarMed Specialist Centre.
The discolouration can also be caused by a rare condition called chromhidrosis, a disorder that causes the sweat glands to produce a pigment compound, he said.Other than the water, trace minerals and waste products that are inherently in sweat, this bodily fluid will also “mix with lipids or oils present on the surface of skin”, said Dr Wang. “After the water component of sweat has evaporated, the other constituents left behind on the skin surface is probably what imparts the sticky feeling.
“In extremely humid conditions, sweat evaporation rates are lower, leading to the accumulation of sweat on the skin. Therefore, you would want to change out of these clothing into loose, clean clothes once you have completed your workout.” Dr Wang isn’t aware of any ill effects of showering whilst still sweaty. “I don't necessarily advise against it,” he said, adding to use a gentle, soap-free cleanser, keep your showers up to twice a day and 10 to 15 minutes each time, and use lukewarm instead of hot water.
