What should a diver do if they feel discomfort during a dive?

If a diver experiences discomfort during a dive, signaling their buddy and ascending slowly is the correct course of action. This approach ensures safety by allowing the diver to communicate their issue, ensuring that assistance is available if needed. Ascending slowly is critical because it helps prevent decompression sickness (DCS), which can occur if a diver ascends too quickly. This gradual ascent allows for the safe release of nitrogen that has been absorbed during the dive, minimizing risks associated with pressure changes.

Ignoring discomfort can lead to further complications, as the diver might be overlooking a potential issue that could escalate. A rapid ascent poses health risks, such as DCS, and does not provide an opportunity to assess or address the discomfort appropriately. Taking a break and floating might provide temporary relief, but it does not address the underlying problem and could put the diver at risk if the issue is more serious. Thus, communicating with a dive buddy and making a slow ascent is the safest and most responsible action for managing discomfort underwater.
