How does the body affect underwater?

Underwater, the body is influenced by increased pressure, which can affect breathing and circulation. The buoyancy of water reduces the strain on joints and muscles, allowing for greater mobility and reduced injury risk. However, the body also faces challenges like potential hypothermia in cold water and the risk of decompression sickness when ascending too quickly from depths. Overall, the underwater environment requires adaptations in physiology and technique for optimal performance and safety.
