Does Peeing on a Jellyfish Sting Actually Help?

The sting of a jellyfish comes from specialized cells in the surface of its tentacles called cnidocytes. Each small, bulb-shaped cell holds a barbed, threadlike tube, called a nematocyst, filled with venom. On the outside of each cell is a tiny hair called a cnicocil. When this “hair trigger” is disturbed, the cell’s toxic harpoon explodes from its capsule and into the skin of the jellyfish’s prey, or an unlucky swimmer.

The amount and type of venom, and the effect that it causes, depends on the type of jellyfish, the number of nematocysts involved, and the area and thickness of the skin they strike. Whatever the variables, a sting is never exactly pleasant.

Often, after a human gets stung, there’s a tentacle or two that gets ripped off and left behind on their skin. The first step to treating the sting is removing the tentacles without triggering any unfired nematocysts and making things worse.

Pressure triggers the cells, so you can’t just pick them off (whoever is doing the picking is just going to get stung on the fingers, too). Certain chemical changes, like throwing off the salt balance between the outside and inside of the cell, can also can also cause the stingers to fire. This is why urine is often no good. Sure, urine contains salts, but it's just too variable. Concentrated urine might do the trick, and there are anecdotal reports from sting victims that it helps relieve some of the pain, but if the peeing rescuer is well-hydrated, the urine will be too diluted with water and make the stingers fire. What’s more, while urine is sterile, it has to pass through the germ-laden urethra to get out, and can lead to a bacterial infection of the sting wound.

What You Can Do Instead of Urinating on Your Friends

So, if Friends lied to us (gasp) and peeing on a sting runs the risk of making matters worse, what should you use to clean and treat the wound? Vinegar is usually the way to go -- just the plain white stuff with 5% acetic acid. It neutralizes unfired nematocysts so they can't sting anymore, and research (see here and here) has shown it to be one of the better post-sting rinses, especially when combined with the topical anaesthetic lidocaine.

When the one-two punch of vinegar and lidocaine isn’t available (and who brings vinegar on a swim?), sea water (the warmer, the better) is also good for rinsing away the remaining nematocysts. Once the stinging cells are deactivated, the stuck bits of tentacle can be picked off or scraped away with a credit card.

A word of caution, though: vinegar might not be the best treatment depending on the creature that stung you. Acetic acid can actually have the opposite of the intended effect on stings from the jellyfish lookalikes in the genus Physalia, like the Portuguese man o' war. If you’re not sure what stung you, stick with sea water or seek help from a lifeguard or medical professional.

12 Creative Ways to Spend Your FSA Money Before the Deadline

If you have a Flexible Spending Account (FSA), chances are, time is running out for you to use that cash. Depending on your employer’s rules, if you don’t spend your FSA money by the end of the grace period, you potentially lose some of it. Lost cash is never a good thing.

For those unfamiliar, an FSA is an employer-sponsored spending account. You deposit pre-tax dollars into the account, and you can spend that money on a number of health care expenses. It’s kind of like a Health Savings Account (HSA), but with a few big differences—namely, your HSA funds roll over from year to year, so there’s no deadline to spend it all. With an FSA, though, most of your funds expire at the end of the year. Bummer.

The good news is: The law allows employers to roll $500 over into the new year and also offer a grace period of up to two and a half months to use that cash (March 15). Depending on your employer, you might not even have that long, though. The deadline is fast approaching for many account holders, so if you have to use your FSA money soon, here are a handful of creative ways to spend it.

1. Buy some new shades.

Head to the optometrist, get an eye prescription, then use your FSA funds to buy some new specs or shades. Contact lenses and solution are also covered.

You can also buy reading glasses with your FSA money, and you don’t even need a prescription.

2. Try acupuncture.

Scientists are divided on the efficacy of acupuncture, but some studies show it’s useful for treating chronic pain, arthritis, and even depression. If you’ve been curious about the treatment, now's a good time to try it: Your FSA money will cover acupuncture sessions in some cases. You can even buy an acupressure mat without a prescription.

If you’d rather go to a chiropractor, your FSA funds cover those visits, too.

3. Stock up on staples.

If you’re running low on standard over-the-counter meds, good news: Most of them are FSA-eligible. This includes headache medicine, pain relievers, antacids, heartburn meds, and anything else your heart (or other parts of your body) desires.

There’s one big caveat, though: Most of these require a prescription in order to be eligible, so you may have to make an appointment with your doctor first. The FSA store tells you which over-the-counter items require a prescription.

4. Treat your feet.

Give your feet a break with a pair of massaging gel shoe inserts. They’re FSA-eligible, along with a few other foot care products, including arch braces, toe cushions, and callus trimmers.

In some cases, foot massagers or circulators may be covered, too. For example, here’s one that’s available via the FSA store, no prescription necessary.

5. Get clear skin.

Yep—acne treatments, toner, and other skin care products are all eligible for FSA spending. Again, most of these require a prescription for reimbursement, but don’t let that deter you. Your doctor is familiar with the rules and you shouldn’t have trouble getting a prescription. And, as WageWorks points out, your prescription also lasts for a year. Check the rules of your FSA plan to see if you need a separate prescription for each item, or if you can include multiple products or drug categories on a single prescription.

While we’re on the topic of faces, lip balm is another great way to spend your FSA funds—and you don’t need a prescription for that. There’s also no prescription necessary for this vibrating face massager.

6. Fill your medicine cabinet.

If your medicine cabinet is getting bare, or you don’t have one to begin with, stock it with a handful of FSA-eligible items. Here are some items that don’t require a prescription:

You can also stock up on first aid kits. You don’t need a prescription to buy those, and many of them come with pain relievers and other medicine.

7. Make sure you’re covered in the bedroom.

Condoms are FSA-eligible, and so are pregnancy tests, monitors, and fertility kits. Female contraceptives are also covered when you have a prescription.

8. Prepare for your upcoming vacation.

If you have a vacation planned this year, use your FSA money to stock up on trip essentials. For example:

9. Get a better night’s sleep.

If you have trouble sleeping, sleep aids are eligible, though you’ll need a prescription. If you want to try a sleep mask, many of them are eligible without a prescription. For example, there’s this relaxing sleep mask and this thermal eye mask.

For those nights you’re sleeping off a cold or flu, a vaporizer can make a big difference, and those are eligible, too (no prescription required). Bed warmers like this one are often covered, too.

Your FSA funds likely cover more than you realize, so if you have to use them up by the deadline, get creative. This list should help you get started, and many drugstores will tell you which items are FSA-eligible when you shop online.

10. Go to the dentist.

While basics like toothpaste and cosmetic procedures like whitening treatments aren’t FSA eligible, most of the expenses you incur at your dentist’s office are. That includes co-pays and deductibles as well as fees for cleanings, x-rays, fillings, and even the cost of braces. There are also some products you can buy over-the-counter without ever visiting the dentist. Some mouthguards that prevent you from grinding your teeth at night are eligible, as are cleaning solutions for retainers and dentures.

11. Try some new gadgets.

If you still have some extra cash to burn, it’s a great time to try some expensive high-tech devices that you’ve been curious about but might not otherwise want to splurge on. The list includes light therapy treatments for acne, vibrating nausea relief bands, electrical stimulation devices for chronic pain, cloud-connected stethoscopes, and smart thermometers.

12. Head to Amazon.

There are plenty of FSA-eligible items available on Amazon, including items for foot health, cold and allergy medication, eye care, and first-aid kits. Find out more details on how to spend your FSA money on Amazon here.

What Is a Scuttlebutt, and Why Do We Like to Hear It?

Casual conversation is home to a variety of prompts. You might ask someone how they’re doing, what’s new, or if they’ve done anything interesting recently. Sometimes, you can ask them what the scuttlebutt is. “What’s the scuttlebutt?” you’d say, for example, and then they’d reply with the solicited scuttlebutt.

We can easily infer that scuttlebutt is a slang term for information or maybe even gossip. But what exactly is scuttlebutt, and why did it become associated with idle water cooler talk?

According to Merriam-Webster, a scuttlebutt referred to a cask on sailing ships in the 1800s that contained drinking water for those on board. It was later used as the name of the drinking fountain found on a ship or in a Naval installation. The cask was known as a butt, while scuttle was taken from the French word escoutilles and means hatch or hole. A scuttlebutt was therefore a hatch in the cask.

Because sailors usually received orders from shouting supervisors, talking amongst themselves was discouraged. Since sailors could congregate around the fountain, it became a place to finally catch up and exchange gossip, making scuttlebutt synonymous with casual conversation. The scuttlebutt was really the only place to do it.

Nautical technology made the scuttlebutt obsolete, but the term endured, becoming a catch-all word for unfounded rumors.

The next time someone asks you what the scuttlebutt is, now you can tell them.
