Does swimming in a chlorinated pool make you break out in red eyes, itchy skin? You might be surprised to learn that chlorine, contrary to popular opinion, is not actually the culprit.

The real problem is a chemical called chloramine, which forms in the water when the level of chlorine is too low.

Bacteria, larvae, microorganisms – swimming pools are a haven for germs. The chlorine solution you pour into your pool will knock most of these on the head. But when it hits the water and touches your skin, the chlorine actually reacts and undergoes a chemical transformation. The result is chloramine – a chemical compound that is produced in pools when chlorine reacts with bodily fluids, changes into other compounds and the pure chlorine level is diluted.  responsible for itchy eyes and smelly skin. At the same time the amount of chlorine in your pool actually drops. The way to actually stop the smell and the irritation? It’s to add more chlorine. Constantly.

If you do suffer from swimming pool side effects, the solution is simple – shower immediately after your swim and use a moisturiser, especially if you have sensitive skin.
