Most often it is a severe burning about 10 minutes after showering, regardless of the water temperature. However a chlorinated spa tub (hot water) seems to relieve it. It does seem to be related to dry skin, however lotion doesn't appear to help. It sometimes makes it worse after applying. Sometimes when not itching, lotion will cause the itch onset. Sweating also seems to bring the itch on.
Why does my skin itch/burn sometimes when it gets wet? (especially after showering or sweating)?
You may have a mild form of urticaria (hives). There is one type, most commonly seen in young men (age approx. 18 to mid 20s) called cholinergic urticaria, which is hives induced by heat. Sweating, warm/hot showers, exercise, strong emotions, anything that raises the core body temperature, can bring out the itching. It usually appears with rash consisting of tiny red bumps, which resolve soon after the body temperature has cooled. Some people find that extremely hot water, like you'd find in a hot tub, actually helps relieve the itch of hives (due to forcing mast cell degranulation), but if you have cholinergic urticaria this can be dangerous, since you can experience a histamine dump from all those mast cells degranulating.
Reply:you should see a allergy specialist for any allergys you may have and also check the components that are in your water there may be a small chance that it could be doing serious harm to your body
