Diving the Red Sea teems with vibrant marine life, but stings and punctures can turn adventure into emergency. Prioritize safety by ending the dive, monitoring vitals, and calling for help if symptoms like breathing trouble or swelling arise. Rinse non-cnidarian wounds - like urchin punctures or lionfish stabs - with freshwater to flush debris and bacteria; for jellyfish or coral stings, use seawater first to neutralize venom and minimize pain.
