Swim a Lap Day takes place on June 24, 2021. It's a day to take your swimming togs and go to a swimming pool to swim one or more laps. There are many reasons why people swim. The largest reason for people swimming is as a recreation activity, with swimming consistently ranking as one of the physical activities people are most likely to take part in. Recreational swimming can be used for people to exercise, to relax or to rehabilitate.
Swimming is consistently found to be amongst the top recreational activities undertaken by the public, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalised sport, swimming features in a range of local, national and international competitions, including featuring in every modern summer Olympics.
Swimming is primarily an aerobic exercise due to the long exercise time, requiring a constant oxygen supply to the muscles, except for short sprints where the muscles work anaerobically. As with most aerobic exercise, swimming is believed to reduce the harmful effects of stress. Swimming can also improve posture. (With material from: Wikipedia)
