As depths approach which depth do symptoms of nitrogen narcosis generally become noticeable?

Symptoms of nitrogen narcosis typically become noticeable as divers approach depths greater than 30 meters (99 feet). At this depth, the increased pressure causes nitrogen, which is a natural component of the air we breathe, to dissolve more readily into the body's tissues. This results in a narcotic effect that can impair a diver's cognitive and physical functions, potentially making them feel euphoric or overly relaxed, and may affect their decision-making abilities.

While symptoms can develop at varying depths depending on the individual and other factors, 30 meters is commonly recognized as the threshold where divers are more likely to experience these effects. Understanding this threshold is crucial for divers, as it directly impacts their safety and decision-making underwater. Recognizing and managing the symptoms of nitrogen narcosis is essential for maintaining effective communication and ensuring a safe diving experience.
