If you suffer from eczema or psoriasis, swimming in public pools with high amounts of chlorine or bromide definitely irritate already irritated skin. However, I think exercise is important and swimming is a wonderful form.
This is against most pool rules, but I tell my patients to apply one of the listed moisturizers in my book (also listed on the product elimination diet website) to the active skin areas before they go swimming to help act as a barrier from the irritants in the pool including the water.
If you don’t have an existing skin issue it’s a good practice is to rinse off right after you get out of the pool with warm water and gently rub your limbs with some friction – no soap or detergent. When you change pat dry and apply a moisturizer from the #producteliminationdiet.
If you have a home pool salt water is better then bromide and the most irritating to the skin is chlorine. I do believe there are some saltwater public pools in cities. Keep swimming!
