What condition is referred to as nitrogen narcosis?

Nitrogen narcosis is a condition that occurs when divers descend to significant depths, where the partial pressure of nitrogen increases. At greater depths, nitrogen becomes more soluble in the body's tissues and can have a narcotic effect on the central nervous system. This results in impaired judgment and cognitive function, akin to the effects of consuming alcohol.

As divers go deeper, they may experience a sense of euphoria or relaxation, but this can also lead to poor decision-making and decreased motor skills, making it crucial for divers to be aware of their depth and the potential impacts of nitrogen narcosis. Understanding this condition is vital for safe diving practices, especially in deeper waters where the risk is heightened.
