Science.
Swimming relies on the nearly neutral buoyancy of the human body. On average, the body has a relative density of 0.98 compared to water, which causes the body to float. However, buoyancy varies on the basis of body composition, lung inflation, and the salinity of the water. Higher levels of body fat and saltier water both lower the relative density of the body and increase its buoyancy.
Since the human body is
will reflexively hold their breath when submerged to protect their airway and are able to survive immersion in water for short periods of time. Infants can also be taken to swimming lessons. Although this may be done to reduce their risk of drowning, the effects on drowning risk are not reliable.
