Does peeing on a jellyfish sting help?

The idea that urinating on a jellyfish sting helps is a common myth. It is not effective and can even make the situation worse.

Jellyfish stings cause pain by injecting toxins through small harpoon-like structures called nematocysts. Urinating on the sting can cause the nematocysts to release more toxins, which can worsen the pain and symptoms. Urine has a variable pH and salt content, which is often not ideal for treating jellyfish stings. The pH of urine can irritate the skin and nematocysts rather than help them.

Immediately rinse the sting with seawater (not fresh water, as this can also stimulate the nematocysts to release more toxins). Fresh water can cause the nematocysts to release more toxins, which can worsen the pain. Carefully remove any remaining tentacles with tweezers or gloves. Never use bare hands, as the tentacles can still sting.

Vinegar can prevent further release of toxins in the Australian sea wasp (Chironex fleckeri). However, this is not effective for all types of jellyfish and can make the situation worse in some cases. Immerse the affected area in warm water (between 40-45°C or 104-113°F) for 20-45 minutes. Heat can help reduce pain by denaturing the venom.

Seek medical attention if the jellyfish sting causes serious symptoms such as difficulty breathing, chest pain, severe pain, or extensive skin reactions.
