Is it possible to sweat while swimming?

Sweating is your bodies way of cooling down. If you are working hard, but still cold in the water, I don’t think you would sweat.

How could you ever tell the difference?

Salt level on the water on your body?

If being chased down by a shark or a crocodile? You betcha life it is!

I wondered the same thing when I was on a swim team for 7 years—and after a few experiments, I concluded, yes, we do sweat while working out in water, but obviously our sweat mixes with the water so we don’t feel it. I don’t think our sweat cells are able to discriminate whether we’re in water or in air, but I could be wrong. Thankfully the chlorine kills whatever bacteria might be swimming in the water.

Yes…big time! I have been a long distance swimmer my whole life and even in cold water my core body temp will be blazing after a workout and always parched borderline dehydrated from sweating and perspiring so much.

Yes, we sweat all the time. Sweating is more from core body temperature than skin temperature. One can get just as dehydrated while swimming as they do running on land.

Here’s an interesting article on the matter.

I think so because when I run I continue to sweat after I stop running and it is the same with a hard swim. I get out of the water and dry off but am soon wet again from sweat.

Yeah, you probably can sweat while in the water but don’t really notice it because you’re already wet…

Ha! @PluckyDog I read the same article and was stunned by the amount of “sweat” during a good work out!

Weigh yourself dry before you swim, then weigh yourself dry after you swim. The amount you lose is the amount of sweat you’ve lost during your workout -you’ll be amazed at how much fluid you’ve lost (and need to replace).

You can sweat while swimming. It goes unnoticed because of the water washing away the sweat. Why do you think swimmers keep water on deck while practicing? It helps restore fluids lost in sweat.
