Deep Breathing Exercise for Nausea

Deep Breathing Exercise for Nausea.jpeg

One of the most common fears patients express when facing surgery is postoperative nausea, which can range from minor queasiness to protracted periods of vomiting. Feeling sick to one's stomach and throwing up after surgery is a common problem, affecting between a quarter and a half of those placed under general anesthesia, and more than half of those at high risk (women who don't smoke and have a history of motion sickness).

I've explored the science behind treating nausea with ginger (see Natural Nausea Remedy Recipe), but if you're too nauseous to eat, what do you do? Well, people are often sent home with anti-nausea rectal suppositories. Surveys, however, show that cultural and sexual attitudes may make a number of people sensitive to anything involving the rectum. Though the wording of the question researchers asked was, "are you happy to have a drug put in your back passage?" I can imagine many of the respondents thinking "well, maybe I wouldn't so much mind, but wouldn't exactly be happy about it," especially when you're feeling sick and throwing up.

For women who've had a C-section, they might not want to take drugs at all if they're breastfeeding, so researchers decided to put aromatherapy to the test. Research has shown that essential oils of both spearmint and peppermint are effective in reducing nausea and vomiting after chemotherapy, but this was after swallowing them.

Would just the smell of peppermint help with nausea? I explore this in my video Peppermint Aromatherapy for Nausea. Researchers had women take deep whiffs of peppermint extract (like you'd buy at a store) and it seemed to work. Eighty percent of the mint-sniffers felt better within just a few minutes, compared to no improvement in the placebo group who sniffed water with green food coloring, or the control group who didn't sniff anything.

The study was criticized for being small and for not using pure peppermint oil. Peppermint extract is peppermint oil plus alcohol. Maybe it was the smell of alcohol that made people better? And that's actually not too much of a stretch. In 1997, researchers reported a simple, innocuous, and inexpensive treatment for postoperative nausea and vomiting--the smell of isopropyl alcohol, which is what is found in those alcohol wipes, the little prep pads that nurses swab you with before shots. They found that they could just effectively tear one open and wave it under someone's nose and relieve nausea and vomiting in more than 80% of folks after surgery. It has been since shown to work as well as a leading anti-nausea drug, and may even work faster, cutting nausea in half within 10 to 15 minutes, rather than 20 or 25.

So was it the alcohol, the peppermint, or both? Researchers decided to put it to the test. They instructed patients to take three slow, deep breaths, smelling alcohol, peppermint, or nothing. The smell of peppermint cut nausea in half within five minutes, and so did the alcohol. But so did smelling nothing! So maybe it had nothing to do with the scent; maybe it was just the instruction to take slow, deep breaths. That would make it a really cost-effective intervention. Maybe it shouldn't be so surprising, given the proximity of the vomiting and breathing centers within the brain.

And indeed, controlled breathing was found effective with or without any scent. So next time you feel nauseous, inhale deeply through your nose to the count of three, hold your breath to the count of three, and exhale out the mouth to the count of three. Do that three times.

Ironically, the researchers continued to advocate using those nasty smelling alcohol pads even though they themselves showed they weren't any more effective than breathing alone. Why? Since isopropyl alcohol has a readily detectable odor, patients are more likely to think that their post-operation nausea and vomiting is being actively treated when they inhale alcohol vapors rather than just engaging in breathing exercises.


What do you think of still using the alcohol pads even though they were shown to offer no additional benefit? I have a whole video on such questions: The Lie That Heals: Should Doctors Give Placebos?

For those who can swallow, I offer more about powdered ginger in my video Dangerous Advice From Health Food Store Employees.

There's more on aromatherapy here:

What about actually eating the peppermint?

Of course, the best way to avoid postsurgical nausea is to try to avoid surgery in the first place. Those that eat healthy may be less likely to go under the knife. See Say No to Drugs by Saying Yes to More Plants.

Can Peppermint Improve Athletic Performance?

NF-Oct20 Enhancing Athletic Performance With Peppermint.jpeg

Ever since smoking was prohibited in night clubs, customers have increasingly noticed other unpleasant smells present in the club--like body odors. So, researchers in Europe thought they'd try to cover them up. The researchers measured the effects of peppermint, for example, on dancing activity and asked people to rate their energy level. They found that with peppermint scent, people felt more cheerful and danced more, and so, concluded the researchers, "environmental fragrancing may be expected to have a positive effects on club revenue." Innovative nightclubs are already inviting "aroma jockeys" to smell the places up.

The business community caught whiff of this and thought maybe peppermint smell would get their secretaries to type faster. And it worked! There was improved performance on clerical tasks associated with the administration of peppermint odor.

In an age where athletic competitions are frequently won or lost by mere hundredths of a second, athletes are continually looking for new ways to excel in their sport. Researchers threw some collegiate athletes onto a treadmill and piped different smell into their nostrils, and those on peppermint reported feeling less fatigued, more vigorous, less frustrated, and felt they performed better. But did they actually perform better? See my video, Enhancing Athletic Performance with Peppermint.

A different study published in the Journal of Sport and Exercise Psychology measured actual performance, and participants were actually able to squeeze out one extra pushup before collapsing and cut almost two seconds off a quarter mile dash with an odorized adhesive strip stuck to their upper lip. Interestingly there was no significant difference in basketball free throws. The researchers think the reason is that free throws actually require some skill, and all the peppermint can do is really improve athlete's motivation.

Unfortunately follow-up studies were not able to replicate these results, showing no beneficial effect of smelling peppermint on athletic performance, so how about eating peppermint? Researchers measured the effects of peppermint on exercise performance before and after ten days of having subjects drink bottles of water with a single drop of peppermint essential oil in them. And all the subjects' performance parameters shot up, churning out 50 percent more work, 20 percent more power, and a 25 percent greater time to exhaustion. Improvements were found across the board in all those physiological parameters, indicating increased respiratory efficiency. They attribute these remarkable results to the peppermint opening up their airways, increasing ventilation and oxygen delivery.

Now, you can overdose on the stuff, but a few drops shouldn't be toxic. Why not get the best of both worls by blending fresh mint leaves in water rather than use the oil?

Sometimes aromatherapy alone may actually help, though:

Beet juice can also enhance athletic performance. See the dozen or so videos in the series starting with Doping With Beet Juice. Other ways healthy food can synergize with exercise:

I use peppermint in my Pink Juice with Green Foam recipe and talk about using the dried in Antioxidants in a Pinch. It can also help reduce IBS symptoms, as seen in Peppermint Oil for Irritable Bowel Syndrome.

Some other tea caveats, though:
