Wait, Should You Actually Pee on a Jellyfish Sting?

You’ve all seen that episode of ‘Friends.’

OK, chances are, you know someone who’s come back from a vacation in Miami or Myrtle Beach, and they enthusiastically recount to you the story of their friend getting stung by a small, non-poisonous jellyfish. And, you guessed it, another friend bravely volunteered their urine to soothe the sting.

“I would never do that,” you might have thought to yourself, cringing at the idea of anyone pointing their stream in the direction of your arm or leg.

But then again, is peeing on a jelly fish sting even necessary? Or have we all just spent decades peeing on each other on beaches for no good reason?

What to Know About Jellyfish Stings

Jellyfish are one of the most beautiful and wondrous creatures to look at, appearing as if they floated right out of a Dr. Seuss book. Despite their sheer bodies with dangling, colorful tentacles, these sea creatures can pose a big threat to humans.

Jellyfish sting in order to paralyze their prey. The venom they release contains tiny stinging cells (called nematocysts), which continue to “fire” poison into the body. That’s why it continues to sting past the initial “zap.”

The real risk to humans is not necessarily from the venom itself, but from our reactions to them. Most fatalities from jellyfish stings come from drowning after being stung (due to the paralyzing effect) or from having an allergic reaction to the jellyfish venom.

Many jellyfish stings simply hurt, but some can be fatal, according to the U.S. National Library of Medicine. These jellyfish contain powerful venom that is more likely to cause serious reactions and even death:

  • Lion’s Mane

  • Portuguese Man-of-War

  • Sea Nettle

  • Box Jellyfish (a.k.a. Sea Wasp)

A box jellyfish can kill humans in a matter of minutes. If you notice breathing difficulties, chest pain, stomach pain, or heavy sweating, get emergency medical attention ASAP.

The Best Way to Treat a Jellyfish Sting

For jellyfish stings that aren’t life-threatening, you can treat the stinging pain yourself. The goal is to “freeze” the stinging cells so they halt their firing process, which relieves you of pain and other complications.

Scientists have studied various liquids to assess which are best for halting the stingers: fresh water, sea water, vinegar, urine, and even kerosene. Sorry to break it to anyone who’s already been peed on because of a jellyfish sting, but urine is *not* the best treatment. In fact, it’s highly discouraged.

Urine and fresh water both make jellyfish stings worse by promoting  the firing of the stinging cells. This can push the toxins deeper into the skin.

Instead, experts recommend using vinegar. Douse the sting site with large amounts of vinegar for at least half a minute, according to the U.S. National Library of Medicine. This should help for all types of jellyfish stings (so you might want to add vinegar to your beach packing list from now on).

The next best choice is sea water. This appears to halt the stinging cells better than fresh water can. Either way, do not rub sand on the sting, scrape or pick at the site, or apply any pressure to the area. Simply rinse with vinegar or sea water.

Then, soak the site of the jellyfish sting in hot tap water for 20 to 40 minutes, and then apply an antihistamine or cortisone cream, which can soothe the itching.

If at any point you notice severe symptoms, such as irregular pulse, nausea, muscle spasms, chills, or difficulty breathing, get medical help. You can also call the Poison Help hotline at any time (even for non-emergencies): 1-800-222-1222.

But let’s get one thing straight: You do *not* have to (and shouldn’t) pee on a jellyfish sting.
