What is the history of swimming?

Swimming is an activity that burns lots of calories, is easy on the joints, supports your weight, builds muscular strength and endurance, improves cardiovascular fitness, cools you off and refreshes you in summer, and one that you can do safely into old age. In this article, I'll review the history of swimming, the benefits, the strokes, how to get started, what to wear, equipment you need, where to do it, and more.

Human beings have been swimming for millennia. According to Wikipedia, Stone Age cave drawings depict individuals swimming and there are written references in the Bible and the Greek poems "The Iliad" and "The Odyssey" dating back 1,500 to 2,000 years. There are even Egyptian clay seals from 4000 BC showing four swimmers doing a version of the crawl, and the most famous swimming drawings were apparently found in the Kebir desert and were estimated to also be from around 4000 BC.

According to the Encyclopedia of Traditional British Rural Sports, literature specifically related to swimming grew in the middle ages. It is believed that the first book devoted to swimming was Colymbetes by Nicolas Wynman written in 1538, and a more widely recognized text, De Arte Nantandi, was published in Latin by Everard Digby in 1587. The encyclopedia also reports that swimming was required of knights and that Romans built bathhouses and pools wherever they conquered to serve as social clubs and places to exercise.

Organized swimming began in the 1800s and 1900s with the creation of swimming associations (for example, the Amateur Swimming Association in 1886) and clubs that competed against each other. There are reports from that era of swimming clubs in England, France, Germany, and the United States. High-profile events also contributed to swimming's visibility. For instance, Matthew Webb swam the English Channel in 1875.

答 :
Human babies can swim from the moment of birth।
Human babies not only float but also, after being born submerged, can swim under their own power, holding their breath until reaching the surface। In the water, the human baby is not helpless. From the moment of birth on, the human baby can swim alongside its mother.
Human babies are born fat, this provides subcutaneous fat to enhance buoyancy।
Baby possess the "diving reflex।"
submerge the baby and the baby will hold its breath until it resurfaces।
Babies lose the diving reflex somewhere between 12 and 18 months।
If baby is placed in water, his throat will close so that he does not swallow the water। This means that baby will not drown if born in water, and he will also be a natural swimmer. This reflex will last for about 2 months, or longer if you take him swimming, i.e. the length mentioned above.
such reflex required our involuntary action to slow down the heart beat and the requirement of breath, therefore, if we lose this reflex as we grow, we need to learn swimming again.
