What should a diver do when another diver shows signs of panic underwater?

When another diver shows signs of panic underwater, the best course of action is to calmly approach and guide them to the surface. This approach is effective because it addresses the immediate need for safety while providing support to the panicked diver. Panic can disrupt the diver's ability to think clearly and manage their buoyancy, potentially leading to dangerous situations such as ascending too rapidly or becoming disoriented.

By calmly approaching them, the supporting diver can help establish a sense of security and control. Guiding the panicking diver to the surface not only facilitates a safe return to a comfortable environment, but it also prevents the situation from escalating into a more serious emergency. This method emphasizes the importance of staying composed and focused, which can help reassure the panicked diver and make the ascent more manageable for both individuals.

Moving away quickly might leave the panicked diver feeling abandoned and increase their anxiety. Shouting to them could further escalate their panic rather than provide the calming influence they need. Responding with panic would only exacerbate the situation. Therefore, calmly guiding them upwards is aimed at ensuring both divers' safety and emotional well-being.
