Which symptom is associated with nitrogen narcosis?

Nitrogen narcosis, often referred to as "the rapture of the deep," occurs when divers breathe nitrogen under high pressures, typically at depths greater than 30 meters (approximately 100 feet). This condition leads to an anesthetic effect that can impair a diver’s cognitive and motor functions.

Loss of judgment or skill is a hallmark symptom of nitrogen narcosis. Divers may find it difficult to make rational decisions, assess situations accurately, or operate their equipment effectively. This impaired judgment can significantly increase the risk of accidents and dangerous situations underwater, making it critical for divers to recognize the symptoms and manage their depth and time to avoid this condition.

In contrast, the other options suggest positive or enhanced abilities, which do not align with the effects of nitrogen narcosis. Understanding the true symptoms, particularly the loss of cognitive function, is crucial for maintaining safety in diving.
