How can divers manage the increased risks associated with shallow water nitrogen narcosis?

Managing the increased risks associated with shallow water nitrogen narcosis primarily revolves around the importance of proper dive planning and adherence to recommended depth limits. Nitrogen narcosis can occur at varying depths, often beginning around 30 feet (9 meters), and it can affect cognitive function, decision-making, and physical coordination.

By sticking to the recommended depths as outlined in training and guidelines, divers can mitigate the risks of narcosis. This includes understanding one’s own susceptibility to narcosis and recognizing how factors such as experience, fatigue, alcohol consumption, and other stresses can individually affect each diver's response to nitrogen at depth. Proper dive planning not only includes depth but also ensures that divers are aware of their limits, have contingency plans, and are prepared for emergencies.

Increasing dive depths, limiting dive time, or frequently ascending and descending can exacerbate the issue rather than alleviate it. Additionally, simply limiting dive time does not address the effects of narcosis, which can occur regardless of how brief the exposure time is at a certain depth. Constantly ascending and descending may not provide effective management and could introduce other risks, such as decompression sickness. Thus, the emphasis on proper dive planning and sticking to recommended depths becomes key in safely managing shallow water
