What is the 120 rule in diving?
The rule suggests that the depth of the dive (in feet) and the time spent underwater (in minutes) should not exceed a combined total of 120. The goal of this rule is to keep divers within a range where they can avoid serious risks such as nitrogen narcosis and decompression sickness. Humans can safely dive to around 1,000 meters before being crushed by pressure, with recreational divers limited to 40 meters and technical divers to approximately 100 meters.For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment.They specialize in either scuba diving (below the surface of water) or deep-sea diving (longer periods of time in depths up to 190 feet).

One important thing to remember is that diving is much more than just breathing through a regulator. Buoyancy, streamlining, swimming and other little details need to be cared for.If divers don’t take their time allowing their lungs and the air to slowly return to normal levels of compression, the gas expands resulting in too much air in the lungs. This can cause tears in the lungs.
