A swimming pool is an enclosed body of water used for swimming or other recreational activities. Swimming pools most commonly use chlorinated or salt water, and may be heated. They can also be used for physical therapy and aquatic sports, as well as training of lifeguards and astronauts. Swimming pools can be either indoors or outdoors and may be public or private.
Swimming is an excellent exercise for children and adults, as it provides a low-impact cardiovascular workout with minimal risk of injury. Swimming can help strengthen and tone muscles, improve balance and coordination, and reduce stress. It also helps burn calories and can be used as a form of weight loss.
All patrons entering the water must pass a swim test prior to use of the deep end of the pool past the lap lanes and the Diving Well. Children under the age of 16 must be accompanied by an adult at all times in the wading pool area. Anyone with a communicable disease, open blisters or cuts, sore ears, eyes, nose, or mouth or excessive sunburn is not allowed in the water. Children in diapers must wear approved swim diapers. Private swim lessons must be registered through the recreation department. Any person providing private instruction may have their membership revoked.
A swimming pool requires daily maintenance, including skimming the surface and emptying the filter. It also needs regular chemical treatment and water testing to ensure a safe environment for swimmers. It also uses a significant amount of electricity to run the pump and heating system. In winter, a pool should be covered with a safety cover that keeps out debris and snow and makes opening the pool in the spring much easier.
