Lastly, and probably most beneficial, swimming in a saltwater pool will not expose you to those extra chemicals that are added to purchased chlorine that make it possible to store and transport it. Purchased chlorine is not just chlorine, it also contains chemical stabilizers and binder agents. Without these stabilizing agents, you would not be able to purchase chlorine in the store because it would have decomposed weeks after leaving the manufacturer. And sunlight decomposes chlorine within a matter of hours. It is these by-products of purchased chlorine that cause most of the discomfort associated with traditional pools, resulting in the usual bleached hair and clothing, and irritation to the eyes.
