Tylenol Could Help Prevent Altitude Sickness


Dedicated mountain climbers will scale mountains regardless of the risks. Now, their loved ones may sleep a little easier, knowing that one of those risks could be reduced by simply taking a common over-the-counter drug. A report on the subject was published in the journal Wilderness and Environmental Medicine.

Altitude sickness, also known as acute mountain sickness (AMS), develops when somebody climbs too high too quickly. Severe AMS can kill you, but the mild version, with its hangover-like headache, nausea, dizziness, and fatigue, is no fun either.

For a long time, doctors’ go-to option for altitude sickness was a drug called acetazolamide. But many people are allergic to acetazolamide, and those that aren’t still don’t enjoy the tingling and burning sensations it can produce in their hands and feet. The alternative to this drug is ibuprofen (a.k.a. Advil or Motrin), which works well but comes with its own suite of nasty side effects.

Researchers wondered if there wasn’t a better option hiding in plain sight. Acetaminophen (a.k.a. Tylenol) is already used to treat many of the same issues as ibuprofen without the gastrointestinal ugliness. Could it also match ibuprofen’s AMS-stopping skills?

To find out, the scientists recruited 332 climbers ascending Mount Everest. They told each person to take either ibuprofen or acetaminophen three times per day as they journeyed upward. When they reached the settlement of Lobuche—16,210 feet above sea level—the climbers were given medical examinations to see if they’d developed AMS.

Unfortunately, a few of them had. Out of 225 climbers who completed the study, 43 showed signs of AMS. Out of those, 18 had taken ibuprofen and 25 were on acetaminophen. In other words, for the majority of mountaineers, both drugs had worked.

The authors acknowledge that their study was small and that more research is needed.

"The best prevention of altitude illness is a slow ascent," they write. "However, proper acclimatization might be ignored or deemed impractical by mountain climbers, hikers, local pilgrims, rescue teams, or military operations."

For these people, the authors note, acetaminophen might be a good choice.

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

The Reason Dogs Are Terrified of Thunderstorms—And How You Can Help

Deafening thunder can be a little scary even for a full-grown human who knows it’s harmless, so your dog’s terror is understandable. But why exactly do thunderstorms send so many of our pawed pals into a tailspin?

Many dogs are distressed by unexpected loud noises—a condition known as noise aversion, or noise phobia in more severe cases—and sudden thunderclaps fall into that category. What separates a wailing siren or fireworks show from a thunderstorm in a dog's mind, however, is that dogs may actually realize a thunderstorm is coming.

As National Geographic explains, not only can dogs easily see when the sky gets dark and feel when the wind picks up, but they can also perceive the shift in barometric pressure that occurs before a storm. The anxiety of knowing loud noise is on its way may upset your dog as much as the noise itself.

Static electricity could also add to this anxiety, especially for dogs with long and/or thick hair. Tufts University veterinary behaviorist Nicholas Dodman, who also co-founded the Center for Canine Behavior Studies, told National Geographic that a static shock when brushing up against metal may heighten your dog’s agitation during a storm.

It’s difficult to nail down why each dog despises thunderstorms. As Purina points out, one could simply be thrown off by a break from routine, while another may be most troubled by the lightning. In any case, there are ways to help calm your stressed pet.

If your dog’s favorite spot during a storm is in the bathroom, they could be trying to stay near smooth, static-less surfaces for fear of getting shocked. Suiting them up in an anti-static jacket or petting them down with anti-static dryer sheets may help.

You can also make a safe haven for your pup where they’ll be oblivious to signs of a storm. Purina behavior research scientist Ragen T.S. McGowan suggests draping a blanket over their crate, which can help muffle noise. For dogs that don’t use (or like) crates, a cozy room with drawn blinds and a white noise machine can work instead.

Consulting your veterinarian is a good idea, too; if your dog’s thunderstorm-related stress is really causing issues, an anti-anxiety prescription could be the best option.
