What are the signs and symptoms of gas narcosis?

Gas narcosis, often related to the effects of inert gases, primarily nitrogen, manifests in several recognizable signs and symptoms that can impact a diver's cognitive and physical abilities. A mild sense of euphoria can occur, creating a feeling of well-being that may lead the diver to underestimate risks. This altered state can result in displays of foolish behavior, where a diver might make decisions they typically wouldn’t on the surface, potentially endangering themselves or their dive team. Additionally, slowed thinking is a common symptom where cognitive processes are impaired, making it difficult for the diver to react quickly or clearly in underwater situations. All these symptoms combined illustrate the broader impacts of gas narcosis, highlighting the need for divers to be aware of their mental state and the possible dangers of deeper dives.
