Explanation: This is a common misconception. In fact, peeing on a jellyfish sting will only worsen the pain. Jellyfish tentacles contain stinging cells called nematocysts. These nematocysts contain venom, which is released when they come into contact with skin. When you pee on a jellyfish sting, the salt in your urine will cause the nematocysts to fire more venom. This will make the pain worse and could lead to further inflammation and tissue damage.

If you are stung by a jellyfish, the best thing to do is to rinse the area with saltwater and apply a cold compress. You can also take an over-the-counter pain reliever, such as ibuprofen or acetaminophen. If the sting is severe, you should seek medical attention.
