Does This Practice Really Hold A Candle To Evidence-Based Medicine?
In Tuesday’s newsletter, we asked you your opinion of ear candling, and got the above-depicted, below-described set of responses:
- Exactly 50% said “Under no circumstances should you put things in your ear and set fire to them”
- About 38% said “It is a safe, drug-free way to keep the ears free from earwax and pathogens”
- About 13% said “Done correctly, thermal-auricular therapy is harmless and potentially beneficial”
This means that if we add the two positive-to-candling answers together, it’s a perfect 50:50 split between “do it” and “don’t do it”.
(Yes, 38%+13%=51%, but that’s because we round to the nearest integer in these reports, and more precisely it was 37.5% and 12.5%)
So, with the vote split, what does the science say?
First, a quick bit of background: nobody seems keen to admit to having invented this. One of the major manufacturers of ear candles refers to them as “Hopi” candles, which the actual Hopi tribe has spent a long time asking them not to do, as it is not and never has been used by the Hopi people. Other proposed origins offered by advocates of ear candling include Traditional Chinese Medicine (not used), Ancient Egypt (no evidence of such whatsoever), and Atlantis:
Quackwatch | Why Ear Candling Is Not A Good Idea
It is a safe, drug-free way to keep the ears free from earwax and pathogens: True or False?
False! In a lot of cases of alternative therapy claims, there’s an absence of evidence that doesn’t necessarily disprove the treatment. In this case, however, it’s not even an open matter; its claims have been actively disproven by experimentation:
- It doesn’t remove earwax; on the contrary, experimentation “showed no removal of cerumen from the external auditory canal. Candle wax was actually deposited in some“
- It doesn’t remove pathogens, and the proposed mechanism of action for removing pathogens, that of the “chimney effect”: the idea that the burning candle creates a vacuum that draws wax out of the ear along with debris and bacteria, simply does not work; on the contrary, “Tympanometric measurements in an ear canal model demonstrated that ear candles do not produce negative pressure”.
- It isn’t safe; on the contrary, “Ear candles have no benefit in the management of cerumen and may result in serious injury”
In a medium-sized survey (n=122), the following injuries were reported:
- 13 x burns
- 7 x occlusion of the ear canal
- 6 x temporary hearing loss
- 3 x otitis externa (this also called “swimmer’s ear”, and is an inflammation of the ear, accompanied by pain and swelling)
- 1 x tympanic membrane perforation
Indeed, authors of one paper concluded:
❝Ear candling appears to be popular and is heavily advertised with claims that could seem scientific to lay people. However, its claimed mechanism of action has not been verified, no positive clinical effect has been reliably recorded, and it is associated with considerable risk.
No evidence suggests that ear candling is an effective treatment for any condition. On this basis, we believe it can do more harm than good and we recommend that GPs discourage its use❞

Under no circumstances should you put things in your ear and set fire to them: True or False?
True! It’s generally considered good advice to not put objects in general in your ears.
Inserting flaming objects is a definite no-no. Please leave that for the Cirque du Soleil.
You may be thinking, “but I have done this and suffered no ill effects”, which seems reasonable, but is an example of survivorship bias in action—it doesn’t make the thing in question any safer, it just means you were one of the one of the ones who got away unscathed.
If you’re wondering what to do instead… Ear oils can help with the removal of earwax (if you don’t want to go get it sucked out at a clinic—the industry standard is to use a suction device, which actually does what ear candles claim to do).

Why Many Nonprofit (Wink, Wink) Hospitals Are Rolling in Money
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
One owns a for-profit insurer, a venture capital company, and for-profit hospitals in Italy and Kazakhstan; it has just acquired its fourth for-profit hospital in Ireland. Another owns one of the largest for-profit hospitals in London, is partnering to build a massive training facility for a professional basketball team, and has launched and financed 80 for-profit start-ups. Another partners with a wellness spa where rooms cost $4,000 a night and co-invests with “leading private equity firms.”
Do these sound like charities?
These diversified businesses are, in fact, some of the country’s largest nonprofit hospital systems. And they have somehow managed to keep myriad for-profit enterprises under their nonprofit umbrella — a status that means they pay little or no taxes, float bonds at preferred rates, and gain numerous other financial advantages.
Through legal maneuvering, regulatory neglect, and a large dollop of lobbying, they have remained tax-exempt charities, classified as 501(c)(3)s.
“Hospitals are some of the biggest businesses in the U.S. — nonprofit in name only,” said Martin Gaynor, an economics and public policy professor at Carnegie Mellon University. “They realized they could own for-profit businesses and keep their not-for-profit status. So the parking lot is for-profit; the laundry service is for-profit; they open up for-profit entities in other countries that are expressly for making money. Great work if you can get it.”
Many universities’ most robust income streams come from their technically nonprofit hospitals. At Stanford University, 62% of operating revenue in fiscal 2023 was from health services; at the University of Chicago, patient services brought in 49% of operating revenue in fiscal 2022.
To be sure, many hospitals’ major source of income is still likely to be pricey patient care. Because they are nonprofit and therefore, by definition, can’t show that thing called “profit,” excess earnings are called “operating surpluses.” Meanwhile, some nonprofit hospitals, particularly in rural areas and inner cities, struggle to stay afloat because they depend heavily on lower payments from Medicaid and Medicare and have no alternative income streams.
But investments are making “a bigger and bigger difference” in the bottom line of many big systems, said Ge Bai, a professor of health care accounting at the Johns Hopkins University Bloomberg School of Public Health. Investment income helped Cleveland Clinic overcome the deficit incurred during the pandemic.
When many U.S. hospitals were founded over the past two centuries, mostly by religious groups, they were accorded nonprofit status for doling out free care during an era in which fewer people had insurance and bills were modest. The institutions operated on razor-thin margins. But as more Americans gained insurance and medical treatments became more effective — and more expensive — there was money to be made.
Not-for-profit hospitals merged with one another, pursuing economies of scale, like joint purchasing of linens and surgical supplies. Then, in this century, they also began acquiring parts of the health care systems that had long been for-profit, such as doctors’ groups, as well as imaging and surgery centers. That raised some legal eyebrows — how could a nonprofit simply acquire a for-profit? — but regulators and the IRS let it ride.
And in recent years, partnerships with, and ownership of, profit-making ventures have strayed further and further afield from the purported charitable health care mission in their community.
“When I first encountered it, I was dumbfounded — I said, ‘This not charitable,’” said Michael West, an attorney and senior vice president of the New York Council of Nonprofits. “I’ve long questioned why these institutions get away with it. I just don’t see how it’s compliant with the IRS tax code.” West also pointed out that they don’t act like charities: “I mean, everyone knows someone with an outstanding $15,000 bill they can’t pay.”
Hospitals get their tax breaks for providing “charity care and community benefit.” But how much charity care is enough and, more important, what sort of activities count as “community benefit” and how to value them? IRS guidance released this year remains fuzzy on the issue.
Academics who study the subject have consistently found the value of many hospitals’ good work pales in comparison with the value of their tax breaks. Studies have shown that generally nonprofit and for-profit hospitals spend about the same portion of their expenses on the charity care component.
Here are some things listed as “community benefit” on hospital systems’ 990 tax forms: creating jobs; building energy-efficient facilities; hiring minority- or women-owned contractors; upgrading parks with lighting and comfortable seating; creating healing gardens and spas for patients.
All good works, to be sure, but health care?
What’s more, to justify engaging in for-profit business while maintaining their not-for-profit status, hospitals must connect the business revenue to that mission. Otherwise, they pay an unrelated business income tax.
“Their CEOs — many from the corporate world — spout drivel and turn somersaults to make the case,” said Lawton Burns, a management professor at the University of Pennsylvania’s Wharton School. “They do a lot of profitable stuff — they’re very clever and entrepreneurial.”
The truth is that a number of not-for-profit hospitals have become wealthy diversified business organizations. The most visible manifestation of that is outsize executive compensation at many of the country’s big health systems. Seven of the 10 most highly paid nonprofit CEOs in the United States run hospitals and are paid millions, sometimes tens of millions, of dollars annually. The CEOs of the Gates and Ford foundations make far less, just a bit over $1 million.
When challenged about the generous pay packages — as they often are — hospitals respond that running a hospital is a complicated business, that pharmaceutical and insurance execs make much more. Also, board compensation committees determine the payout, considering salaries at comparable institutions as well as the hospital’s financial performance.
One obvious reason for the regulatory tolerance is that hospital systems are major employers — the largest in many states (including Massachusetts, Pennsylvania, Minnesota, Arizona, and Delaware). They are big-time lobbying forces and major donors in Washington and in state capitals.
But some patients have had enough: In a suit brought by a local school board, a judge last year declared that four Pennsylvania hospitals in the Tower Health system had to pay property taxes because its executive pay was “eye popping” and it demonstrated “profit motives through actions such as charging management fees from its hospitals.”
A 2020 Government Accountability Office report chided the IRS for its lack of vigilance in reviewing nonprofit hospitals’ community benefit and recommended ways to “improve IRS oversight.” A follow-up GAO report to Congress in 2023 said, “IRS officials told us that the agency had not revoked a hospital’s tax-exempt status for failing to provide sufficient community benefits in the previous 10 years” and recommended that Congress lay out more specific standards. The IRS declined to comment for this column.
Attorneys general, who regulate charity at the state level, could also get involved. But, in practice, “there is zero accountability,” West said. “Most nonprofits live in fear of the AG. Not hospitals.”
Today’s big hospital systems do miraculous, lifesaving stuff. But they are not channeling Mother Teresa. Maybe it’s time to end the community benefit charade for those that exploit it, and have these big businesses pay at least some tax. Communities could then use those dollars in ways that directly benefit residents’ health.

Non-Sleep Deep Rest: A Neurobiologist’s Take
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
How to get many benefits of sleep, while awake!
Today we’re talking about Dr. Andrew Huberman, a neuroscientist and professor in the department of neurobiology at Stanford School of Medicine.
He’s also a popular podcaster, and as his Wikipedia page notes:
❝In episodes lasting several hours, Huberman talks about the state of research in a specific topic, both within and outside his specialty❞
Today, we won’t be taking hours, and we will be taking notes from within his field of specialty (neurobiology). Specifically, in this case:
Non-Sleep Deep Rest (NSDR)
What is it? To quote from his own dedicated site on the topic:
❝What is NSDR (Yoga Nidra)? Non-Sleep Deep Rest, also known as NSDR, is a method of deep relaxation developed by Dr. Andrew Huberman, a neuroscientist at Stanford University School of Medicine.
It’s a process that combines controlled breathing and detailed body scanning to bring you into a state of heightened awareness and profound relaxation. The main purpose of NSDR is to reduce stress, enhance focus, and improve overall well-being.❞
While it seems a bit bold of Dr. Huberman to claim that he developed yoga nidra, it is nevertheless reassuring to get a neurobiologist’s view on this:
How it works, by science
Dr. Huberman says that by monitoring EEG readings during NSDR, we can see how the brain slows down. Measurably!
- It goes from an active beta range of 13–30 Hz (normal waking) to a conscious meditation state of an alpha range of 8–13 Hz.
- However, with practice, it can drop further, into a theta range of 4–8 Hz.
- Ultimately, sustained SSDR practice can get us to 0.5–3 Hz.
This means that the brain is functioning in the delta range, something that typically only occurs during our deepest sleep.
You may be wondering: why is delta lower than theta? That’s not how I remember the Greek alphabet being ordered!
Indeed, while the Greek alphabet goes alpha beta gamma delta epsilon zeta eta theta (and so on), the brainwave frequency bands are:
- Gamma = concentrated focus, >30 Hz
- Beta = normal waking, 13–30 Hz
- Alpha = relaxed state, 8–13 Hz
- Theta = light sleep, 4–8 Hz
- Delta = deep sleep, 1–4 Hz
Source: Sleep Foundation ← with a nice infographic there too
NSDR uses somatic cues to engage our parasympathetic nervous system, which in turn enables us to reach those states. The steps are simple:
- Pick a time and place when you won’t be disturbed
- Lie on your back and make yourself comfortable
- Close your eyes as soon as you wish, and now that you’ve closed them, imagine closing them again. And again.
- Slowly bring your attention to each part of your body in turn, from head to toe. As your attention goes to each part, allow it to relax more.
- If you wish, you can repeat this process for another wave, or even a third.
- Find yourself well-rested!
Note: this engagement of the parasympathetic nervous system and slowing down of brain activity accesses restorative states not normally available while waking, but 10 minutes of NSDR will not replace 7–9 hours of sleep; nor will it give you the vital benefits of REM sleep specifically.
So: it’s an adjunct, not a replacement

Fast. Feast. Repeat – by Dr. Gin Stephens
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’ve reviewed intermittent fasting books before, so what makes this one different?
The title “Fast. Feast. Repeat.” doesn’t give much away; after all, we already know that that’s what intermittent fasting is.
After taking the reader though the basics of how intermittent fasting works and what it does for the body, much of the rest of the book is given over to improvements.
That’s what the real strength of this book is: ways to make intermittent fasting more efficient, including how to avoid plateaus. After all, sometimes it can seem like the only way to push further with intermittent fasting is to restrict the eating window further. Not so!
Instead, Dr. Stephens gives us ways to keep confusing our metabolism (in a good way) if, for example, we had a weight loss goal we haven’t met yet.
Best of all, this comes without actually having to eat less.
Bottom line: if you want to be in good physical health, and/but also believe that life is for living and you enjoy eating food, then this book can resolve that age-old dilemma!

Dangers Of Root Canals And Crowns, & What To Do Instead
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Michelle Jorgensen, a dentist, tells us that it’s a lot rarer than people think to actually need a crown or a root canal; there are ways of avoiding such:
The tooth, the whole tooth, and nothing but the tooth?
First, some of the problems with the treatments that are most popular, especially in the US:
Problems with root canals:
- Involves cleaning and filling the tooth’s main canal but leaves microtubules that can harbor dead tissue and attract bacteria.
- This can lead to infections, often undetected for a long time due to the nerve removal, potentially harming overall health and weakening the tooth.
- Root canals often result in brittle teeth that can break, necessitating crowns.
And then…
Problems with crowns:
- A crown requires significant removal of tooth structure (up to 1.5 mm of enamel), making the tooth more vulnerable and sensitive.
- Crowns can also lead to new cavities underneath due to weak bonding to dentin.
- The cycle often leads from a healthy tooth to fillings, crowns, root canals, and eventual extraction (and then, perhaps, an implant in its place). That’s great for the dentist, but not so great for you.
Biomimetic dentistry the exciting name currently being used for what has been more prosaically called “conservative restorative dentistry”, which in turn has also been known by other names in recent decades, and its goal is to strengthen and preserve natural teeth as much as possible.
Methods it uses:
- Treats affected but still living teeth with non-invasive procedures.
- Uses ozone treatment to kill bacteria in deep cavities, avoiding direct nerve exposure.
- Applies conservative partial restorations like onlays instead of full crowns.
Benefits of this approach:
- Preserves enamel, minimizes trauma, and reduces the risk of tooth death.
- Maintains long-term tooth structure and health.
- 95% success rate in saving affected teeth without resorting to root canals.
In short, Dr. Jorgensen says that 60–80% of traditional crowns and root canals can be avoided. Which is surely a good thing.

The End of Old Age – by Dr. Marc Agronin
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
First, what this book is not: a book about ending aging. For that, you would want to check out “Ending Aging”, by Dr. Aubrey de Grey.
What this book actually is: a book about the purpose of aging. As in: “aging: to what end?”, and then the book answers that question.
Rather than viewing aging as solely a source of decline, this book (while not shying away from that) resolutely examines the benefits of old age—from clinically defining wisdom, to exploring the many neurological trade-offs (e.g., “we lose this thing but we get this other thing in the process”), and the assorted ways in which changes in our brain change our role in society, without relegating us to uselessness—far from it!
The style of the book is deep and meaningful prose throughout. Notwithstanding the author’s academic credentials and professional background in geriatric psychiatry, there’s no hard science here, just comprehensible explanations of psychiatry built into discussions that are often quite philosophical in nature (indeed, the author additionally has a degree in psychology and philosophy, and it shows).
Bottom line: if you’d like your own aging to be something you understand better and can actively work with rather than just having it happen to you, then this is an excellent book for you.

Drug companies pay doctors over A$11 million a year for travel and education. Here’s which specialties received the most
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Drug companies are paying Australian doctors millions of dollars a year to fly to overseas conferences and meetings, give talks to other doctors, and to serve on advisory boards, our research shows.
Our team analysed reports from major drug companies, in the first comprehensive analysis of its kind. We found drug companies paid more than A$33 million to doctors in the three years from late 2019 to late 2022 for these consultancies and expenses.
We know this underestimates how much drug companies pay doctors as it leaves out the most common gift – food and drink – which drug companies in Australia do not declare.
Due to COVID restrictions, the timescale we looked at included periods where doctors were likely to be travelling less and attending fewer in-person medical conferences. So we suspect current levels of drug company funding to be even higher, especially for travel.
What we did and what we found
Since 2019, Medicines Australia, the trade association of the brand-name pharmaceutical industry, has published a centralised database of payments made to individual health professionals. This is the first comprehensive analysis of this database.
We downloaded the data and matched doctors’ names with listings with the Australian Health Practitioner Regulation Agency (Ahpra). We then looked at how many doctors per medical specialty received industry payments and how much companies paid to each specialty.
We found more than two-thirds of rheumatologists received industry payments. Rheumatologists often prescribe expensive new biologic drugs that suppress the immune system. These drugs are responsible for a substantial proportion of drug costs on the Pharmaceutical Benefits Scheme (PBS).
The specialists who received the most funding as a group were cancer doctors (oncology/haematology specialists). They received over $6 million in payments.
This is unsurprising given recently approved, expensive new cancer drugs. Some of these drugs are wonderful treatment advances; others offer minimal improvement in survival or quality of life.
A 2023 study found doctors receiving industry payments were more likely to prescribe cancer treatments of low clinical value.
Our analysis found some doctors with many small payments of a few hundred dollars. There were also instances of large individual payments.
Why does all this matter?
Doctors usually believe drug company promotion does not affect them. But research tells a different story. Industry payments can affect both doctors’ own prescribing decisions and those of their colleagues.
A US study of meals provided to doctors – on average costing less than US$20 – found the more meals a doctor received, the more of the promoted drug they prescribed.
Another study found the more meals a doctor received from manufacturers of opioids (a class of strong painkillers), the more opioids they prescribed. Overprescribing played a key role in the opioid crisis in North America.
Overall, a substantial body of research shows industry funding affects prescribing, including for drugs that are not a first choice because of poor effectiveness, safety or cost-effectiveness.
Then there are doctors who act as “key opinion leaders” for companies. These include paid consultants who give talks to other doctors. An ex-industry employee who recruited doctors for such roles said:
Key opinion leaders were salespeople for us, and we would routinely measure the return on our investment, by tracking prescriptions before and after their presentations […] If that speaker didn’t make the impact the company was looking for, then you wouldn’t invite them back.
We know about payments to US doctors
The best available evidence on the effects of pharmaceutical industry funding on prescribing comes from the US government-run program called Open Payments.
Since 2013, all drug and device companies must report all payments over US$10 in value in any single year. Payment reports are linked to the promoted products, which allows researchers to compare doctors’ payments with their prescribing patterns.
Analysis of this data, which involves hundreds of thousands of doctors, has indisputably shown promotional payments affect prescribing.
US research also shows that doctors who had studied at medical schools that banned students receiving payments and gifts from drug companies were less likely to prescribe newer and more expensive drugs with limited evidence of benefit over existing drugs.
In general, Australian medical faculties have weak or no restrictions on medical students seeing pharmaceutical sales representatives, receiving gifts, or attending industry-sponsored events during their clinical training. They also have no restrictions on academic staff holding consultancies with manufacturers whose products they feature in their teaching.
So a first step to prevent undue pharmaceutical industry influence on prescribing decisions is to shelter medical students from this influence by having stronger conflict-of-interest policies, such as those mentioned above.
A second is better guidance for individual doctors from professional organisations and regulators on the types of funding that is and is not acceptable. We believe no doctor actively involved in patient care should accept payments from a drug company for talks, international travel or consultancies.
Third, if Medicines Australia is serious about transparency, it should require companies to list all payments – including those for food and drink – and to link health professionals’ names to their Ahpra registration numbers. This is similar to the reporting standard pharmaceutical companies follow in the US and would allow a more complete and clearer picture of what’s happening in Australia.
Patients trust doctors to choose the best available treatments to meet their health needs, based on scientific evidence of safety and effectiveness. They don’t expect marketing to influence that choice.
