Before trying the popular remedy of urinating on a jellyfish sting—or letting someone urinate on you—consider the evidence from medical research.
A study published two years ago in the peer-reviewed journal Toxins tested various treatments on jellyfish stings. Researchers found urine offers no benefit and can worsen pain in some cases. Urine composition varies based on diet, hydration, and other factors, potentially introducing chemicals that intensify the sting's burning sensation on affected skin.
Avoid scraping off tentacles, as often suggested. Instead, gently remove them with tweezers. Rinse the area immediately with vinegar, which neutralizes the venom effectively. No vinegar? Use warm fresh water—but never seawater, as it can trigger more venom release.
