Why is nitrogen narcosis dangerous?
In itself, nitrogen narcosis is not life threatening. The danger occurs from poor decision making while under the effects of nitrogen narcosis. A diver affected by nitrogen narcosis behaves as you might expect someone to behave if intoxicated. Narcosis will impair both the coordination and judgement of a diver, sometimes causing a false sense of security which results in foolish behaviour and a disregard for safety. Sometimes, nitrogen narcosis can make a diver feel anxious and uncomfortable, which can lead to higher stressed and panic states, which can result in making poor decisions.
