Experts recommend swimming equipment for everyone, especially for beginners to avoid the harmful effects of water. It is essential to use earplugs to block water from entering the ear canal during swimming. Some swimmers also like to use nose clips to stop water from entering the nose. Pools usually contain high levels of chlorine and other chemicals to control the algae growth and keep the water free of bacteria. Thus, a person needs goggles and swims caps to protect the hair and eyes.
