Which symptom is NOT typically associated with nitrogen narcosis?

Nitrogen narcosis, often experienced by divers at depths greater than 30 meters (about 100 feet), is a phenomenon caused by the increased partial pressure of nitrogen in the body. The symptoms associated with nitrogen narcosis include various cognitive and sensory changes due to this pressure.

Altered judgment is a well-documented symptom, as divers may experience impaired decision-making abilities, leading them to underestimate risks or engage in unsafe behaviors. Dizziness can also occur, contributing to a feeling of disorientation. Visual disturbances can include blurred vision or difficulty focusing, further affecting a diver's ability to navigate or assess their surroundings.

In contrast, increased physical strength is not a symptom of nitrogen narcosis. While divers may feel a temporary sense of euphoria or invincibility, the actual physiological effects of being narced do not enhance physical strength. Instead, divers typically experience diminished physical coordination and reaction times, which can create a greater risk while diving. Understanding the correct symptoms of nitrogen narcosis is crucial for ensuring safety in diving environments.
