Scuba

: As you descend, the surrounding pressure increases, causing the air in your lungs, wetsuit, and BCD to compress. This requires more air for neutral buoyancy and significantly increases air consumption.

For deeper or more complex dives, standard equipment is supplemented with redundant systems: : As you descend, the surrounding pressure increases,

: At significant depths, nitrogen becomes narcotic, often described as a "euphoric" or "peaceful" feeling that can impair judgment. Additionally, the risk of oxygen toxicity increases, especially when using enriched air like Nitrox 32% , which has a maximum operating depth of 121 feet. : As you descend
