Many allergy sufferers note increasing symptoms of eye irritation, nasal comngestion, itchy eczema and even respiratory wheeze when exposed to high levels of chlorine in swimming pools. Although not a recognised allergen, chlorinated water (particularly in indoor swimming pools) may cause allergy-like symptoms when high levels are encountered in the water and surrounding air. Irritant contact eczema and lung irritation may be a delayed Type 4 hypersensitivity. Eye lid and conjunctival symptoms can be exacerbated by rubbing which causes further contact irritation, eczema and conjunctival chemosis. After swimming, wash thoroughly with fresh water, and apply plenty of skin moisturiser after swimming. Public swimming pools should be routinely checked to ensure chlorine in water remain at acceptable levels.
