People cannot breathe underwater without assistance from oxygen tanks and rebreathers, or air pumps. It is currently impossible to draw enough oxygen out of water to sustain a human, so we rely on carrying the air down with us, or drawing it down from the surface on demand. Oxygen tanks can last multiple hours, but a pump system will operate as long as it has fuel.

The amount of time a person can stay underwater varies depending on factors such as breath-holding ability, physical fitness, and water temperature. On average, most people can hold their breath for 30 seconds to 2 minutes. Professional free divers can stay submerged for several minutes. However, it is essential to prioritize safety and never push your limits.
