Does human urine help jellyfish stings?
Despite what you may have heard, it’s a myth that peeing on a jellyfish sting does anything to ease the pain. Not only are there no studies to support this idea, but urine may actually worsen the sting, too. To explain why, let’s turn to emergency medicine specialist Thomas Waters, MD.

Jellyfish are not very smart. “They have very simple sensory organs, and no brain to process any information,” says marine biologist Stein Kaartvedt. Which is why it’s so interesting that, off the coast of Norway, scientists have observed what they’re calling “apparent social behavior” in the helmet jellyfish.
