What to do about Jellyfish Stings

Jellyfish stings are responsible for more deaths than shark attacks each year. Even "mild" stings can hurt for hours, or sometimes days, and leave lasting scars. According to some estimates, more than 150 million people are stung by jellyfish each year.

Scientists have now found overwhelming evidence that applying hot packs, or immersing in hot water, is much better for treating jellyfish stings than the cold water which was previously widely recommended.

The researchers, Christie Wilcox and Angel Yanagihara from the University of Hawaii at Manoa, trawled through more than 2,000 articles in major scientific journals to find every study to date that looked at using temperature-based treatments for jellyfish stings. They found that the data conclusively supported immersing in hot water, finding that the venom is inactivated at temperatures between 40 and 50 degrees Celsius.

"I was shocked that the science was so clear, given that there is so much debate over the use of hot water," said Wilcox. Hot-water immersion is already the standard of care for other severe marine stings including those from the potentially life-threatening stonefish. "It's simple, really: If you're stung, use hot water or hot packs rather than ice or cold packs."

The scientists concluded that immersing a stung limb in 45 oC water for 20 minutes has no ill effects, is a safe and effective method of reducing pain and improves the outcome of the sting.

So, if you're stung by a jellyfish, you know what to do.
