Hot chlorinated water outgasses more chlorine gas and keeping chlorine levels as low was possible is advised. There are alternatives. Chlorine filters for the whole house or the shower/faucets only. There are also other sanitization methods like ozon treatment together with the use of sodium chlorocyanurate, bromine, mico-filtration, UV, and silver/copper sanitizers which work with very low chlorine levels. Chlorine is so popular because it's cheap. The recommended chlorine levels for public pools in the USA is 4ppm. The limit in Europe is 0.6.
