Swimming is a form of exercise that burns a lot of calories, increases your cardiovascular fitness levels, improves your muscular endurance and strength, does not impact the joints due to the water supporting your weight, refreshes and cools you in hot weather, and which can be done safely even in old age.
The basic principle of swimming is buoyancy. The human body has high water content and its density is close to the density of water. Due to its cavities (most prominently the lungs), the average density of the human body is lower than that of water, so it naturally floats.
