What is nitrogen narcosis?

Nitrogen narcosis is a condition that occurs when divers descend to depths greater than approximately 30 meters (or 100 feet). At these depths, the partial pressure of nitrogen increases significantly, leading to greater absorption of nitrogen into the body, particularly into the brain. This increased nitrogen can have a narcotic effect, impairing cognitive functions and leading to symptoms similar to intoxication, such as euphoria, confusion, and poor judgment. The threshold of 30 meters is commonly referenced in diving as a critical depth where divers may begin to experience these effects, making it essential for divers to be aware of their depth and maintain their awareness while underwater. Recognizing the effects of nitrogen narcosis is crucial for safe diving practices.
