The depth most commonly associated with the term safety stop is 15-20 feet (5-6 m). Divers are taught to remain at this depth for at least three to five minutes, as it allows the body to offgas nitrogen accumulated in the tissues while at depth.
How do free divers survive?
Freedivers train themselves to not give in to that urge of breathing that our body sends after about a minute or so and to ignore the rising of carbon dioxide in the body during a dive. The key to lasting longer underwater is to get used to taking slow, deep breaths in advance to a dive.
