Chlorine is a highly toxic chemical that helps to disinfect public water systems. The chemical element kills pathogens and prevents the spread of waterborne illnesses. While there are several excellent benefits of chlorine, excessive exposure to the chemical can cause skin irritations and aggravate conditions like rosacea and eczema and cause dry, flaky, and itchy skin.
Because chlorine evaporates naturally over time, most water systems are now using chloramines (chemical compounds of chlorine and ammonia) to disinfect water. As opposed to chlorine, chloramines last longer and require specialized filtration systems to extract them from water. The problem here is that even though the use of safe amounts of chloramine is allowed in public water systems, there are no studies that confirm that it is indeed safe. Many reports suggest that chloramines can weaken the immune system, which can lead to scaling and flaking of the skin, rashes, and other skin problems. Since chlorine is known to cause skin irritations, it’s only fair to assume that chloramines might pose a more significant threat to the skin.
