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). For information on safely getting rid of earwax, see our previous article:

Unprocessed – by Kimberly Wilson

First, what this is not: hundreds of pages to say “eat less processed food”. That is, of course, also advisable (and indeed, is advised in the book too), but there’s a lot more going on here too.
Though not a doctor, the author is a psychologist who brings a lot of data to the table, especially when it comes to the neurophysiology at hand, what forgotten micronutrients many people are lacking, and what trends in society worsen these deficiencies in the population at large.
If you only care about the broadest of take-away advice, it is: eat a diet that’s mostly minimally processed plants and some oily fish, watch out for certain deficiencies in particular, and increase dietary intake of them where necessary (with taking supplements as a respectable next-best remedy).
On which note, a point of criticism is that there’s some incorrect information about veganism and brain health; she mentions that DHA is only found in fish (in fact, fish get it from algae, which has it, and is the basis of many vegan omega-3 supplements), and the B12 is found only in animals (also found in yeast, which is not an animal, as well as various bacteria in soil, and farm animals get their B12 from supplements these days anyway, so it is arguable that we could keep things simpler by just cutting out the middlecow).
However, the strength of this book really is in the delivery of understanding about why certain things matter. If you’re told “such-and-such is good for the brain”, you’ll up your intake for 1–60 days, depending on whether you bought a supermarket item or ordered a batch of supplements. And then you’ll forget, until 6–12 months later, and you’ll do it again. On the other hand, if you understand how something is good or bad for the brain, what it does (for good or ill) on a cellular level, the chemistry and neurophysiology at hand, you’ll make new habits for life.
The style is middle-range pop-science; by this we mean there are tables of data and some long words that are difficult to pronounce, but also it’s not just hard science throughout—there’s (as one might expect from an author who is a psychologist) a lot about the psychology and sociology of why many people make poor dietary decisions, and the things governments often do (or omit doing) that affect this adversely—and how we can avoid those traps as individuals (unless we be incarcerated or such).
As an aside, the author is British, so governmental examples are mostly UK-based, but it doesn’t take a lot to mentally measure that against what the governments of, for example, the US or Canada do the same or differently.
Bottom line: there’s a lot of great information about brain health here; the strongest parts are whether the author stays within her field (psychology encompasses such diverse topics as neurophysiology and aspects of sociology, but not microbiology, for example). If you want to learn about the physiology of brain health and enjoy quite a sociopolitical ride along the way, this one’s a good one for that.

Life Lessons From A Brain Surgeon – by Dr. Rahul Jandial
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.
In the category of surgeons with a “what to put on your table to stay off mine” angle, this book packs an extra punch. As well as being an experienced brain surgeon, Dr. Jandial also does a lot of cutting edge lab research too. What does this mean for us?
This book gives, as the subtitle promises, “practical strategies for peak health and performance”—with a brain-centric bias, of course.
From diet and nootropic supplements, to exercise and brain-training, we get a good science-based view of which ones actually work, and which don’t. The style is also very readable; Dr. Jandial is a great educator, presenting genuine scientific content with very accessible language.
Bottom line: if you’d indeed like to look after your most important organ optimally, this book gives a lot of key pointers, without unnecessary fluff.

Clams vs Oysters – Which is Healthier?
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.
Our Verdict
When comparing clams to oysters, we picked the clams.
Why?
Considering the macros first, clams have more than 2x the protein, while oysters have nearly 2x the fat, of which, a little over 5x the saturated fat. So, in all accounts, clam is the winner here.
In terms of vitamins, clams have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, B12, and C, while oysters are not higher in any vitamins. Another win for clams.
The category of minerals is more balanced; clams are higher in manganese, phosphorus, potassium, and selenium, while oysters are higher in copper, iron, magnesium, and zinc. This makes for a 4:4 tie, though it’s worth noting that the margin of difference for zinc is very large, so that can be an argument for oysters.
Nevertheless, adding up the sections makes for a clear win for clams.
A quick aside on “are oysters an aphrodisiac?”:
That zinc content is probably largely responsible for oysters’ reputation as an aphrodisiac, and zinc is important in the synthesis of both estrogen and testosterone. However, as the synthesis is not instant, and those sex hormones rise most in the morning (around 8am to 9am), to enjoy aphrodisiac benefits it’d be more sensible, on a biochemical level, to eat oysters one day, and then have morning sex the next day when those hormones are peaking. That said, while testosterone is the main driver of male libido, progesterone is usually more relevant for women’s, and unlike estrogen, progesterone usually peaks around 10pm to 2am, and is uninfluenced by having just eaten oysters.
So, in what way, if any, could oysters be responsible for libido in women? Well, the zinc is still important in energy metabolism, so that’s a factor, and also, we might hypothesize that oysters’ high saturated fat and cholesterol content may increase blood pressure which, while not fabulous for the health in general, may be considered desirable in the bedroom since the clitoris is anatomically analogous to the penis, and—while estrogen vs testosterone makes differences to the nervous system down there that are beyond the scope of today’s article—also enjoys localized increased blood pressure (and thus, a flushing response and resultant engorgement) during arousal.

Nanotechnology vs Alcohol Damage!
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 Thing That Does Pair Well With Alcohol…
Alcohol is not a healthy thing to consume. That shouldn’t be a controversial statement, but there is a popular belief that it can be good for the heart:
Red Wine & The Heart: Can We Drink To Good Health?
The above is an interesting and well-balanced article that examines the arguments for health benefits (including indirectly, e.g. social aspects).
Ultimately, though, as the World Health Organization puts it:
WHO: No level of alcohol consumption is safe for our health
There is some good news:
We can somewhat reduce the harm done by alcohol by altering our habits slightly:
How To Make Drinking Less Harmful
…and we can also, of course, reduce our alcohol consumption (ideally to zero, but any reduction is an improvement already):
And, saving the best news (in this section, anyway) for last, it is almost always possible to undo the harm done specifically to one’s liver:
Nanotechnology to the rescue?
Remember when we had a main feature about how colloidal gold basically does nothing by itself (and that that’s precisely why gold is used in medicine, when it is used)?
Now it has an extra bit of nothing to do, for our benefit (if we drink alcohol, anyway), as part of a gel that detoxifies alcohol before it can get to our liver:
Gold is one of the “ingredients” in a gel containing a nanotechnology lattice of protein fibrils coated with iron (and the gold is there as an inert catalyst, which is chemistry’s way of saying it doesn’t react in any way but it does cheer the actual reagents on). There’s more chemistry going on than we have room to discuss in our little newsletter, so if you like the full details, you can read about that here:
Single-site iron-anchored amyloid hydrogels as catalytic platforms for alcohol detoxification
The short and oversimplified explanation is that instead of alcohol being absorbed from the gut and transported via the bloodstream to the liver, where it is metabolized (poisoning the liver as it goes, and poisoning the rest of the body too, including the brain), the alcohol is degraded while it is still in the gastrointestinal tract, converted by the gel’s lattice into acetic acid (which is at worst harmless, and actually in moderation a good thing to have).
Even shorter and even more oversimplified: the gel turns the alcohol into vinegar in the stomach and gut, before it can get absorbed into the blood.
But…
Of course there’s a “but”…
There are some limitations:
It doesn’t get it all (tests so far found it only gets about half of the alcohol), and so far it’s only been tested on mice, so it’s not on the market yet—while the researchers are sufficiently confident about it that a patent application has now been made, though, so it’ll probably show up on the market in the near future.
You can read a pop-science article about it (with diagrams!) here:
New gel breaks down alcohol in the body

We’ve reviewed quite a number of books about quitting alcohol, so it’s hard to narrow it down to a single favorite, but after some deliberation, we’ll finish today with recommending:

Hope Not Nope – by Dr. Dillon Caswell
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.
The author a Doctor of Physical Therapy, writes from both professional expertise and personal experience, when it comes to the treatment of long term injury / disability / chronic illness.
His position here is that while suffering is unavoidable, we don’t have to suffer as much or as long as many might tell us. We can do things to crawl and claw our way to a better position, and we do not have to settle for any outcome we don’t want. That doesn’t mean there’s always a miracle cure—we don’t get to decide that—but we do get to decide whether we keep trying.
Dr. Caswell’s advice is based mostly in psychology—a lot of it in sports psychology, which is no surprise given his long history as an athlete as well as his medical career.
The style is very easy-reading, and a combination of explanation, illustrative (often funny) anecdotes, and a backbone of actual research to keep everything within the realms of science rather than mere wishful thinking—he strikes a good balance.
Bottom line: if your current health outlook is more of an uphill marathon, then this book can give you the tools to carry yourself through the healthcare system that’s been made for numbers, not people.

The Mental Health First-Aid That You’ll Hopefully Never Need
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.
Take Your Mental Health As Seriously As General Health!
Sometimes, health and productivity means excelling—sometimes, it means avoiding illness and unproductivity. Both are essential, and today we’re going to tackle some ground-up stuff. If you don’t need it right now, great; we suggest to read it for when and if you do. But how likely is it that you will?
- One in four of us are affected by serious mental health issues in any given year.
- One in five of us have suicidal thoughts at some point in our lifetime.
- One in six of us are affected to at least some extent by the most commonly-reported mental health issues, anxiety and depression, in any given week.
…and that’s just what’s reported, of course. These stats are from a UK-based source but can be considered indicative generally. Jokes aside, the UK is not a special case and is not measurably worse for people’s mental health than, say, the US or Canada.
While this is not an inherently cheery topic, we think it’s an important one.
Depression, which we’re going to focus on today, is very very much a killer to both health and productivity, after all.
One of the most commonly-used measures of depression is known by the snappy name of “PHQ9”. It stands for “Patient Health Questionnaire Nine”, and you can take it anonymously online for free (without signing up for anything; it’s right there on the page already):
Take The PHQ9 Test Here! (under 2 minutes, immediate results)
There’s a chance you took that test and your score was, well, depressing. There’s also a chance you’re doing just peachy, or maybe somewhere in between. PHQ9 scores can fluctuate over time (because they focus on the past two weeks, and also rely on self-reports in the moment), so you might want to bookmark it to test again periodically. It can be interesting to track over time.
In the event that you’re struggling (or: in case one day you find yourself struggling, or want to be able to support a loved one who is struggling), some top tips that are useful:
Accept that it’s a medical condition like any other
Which means some important things:
- You/they are not lazy or otherwise being a bad person by being depressed
- You/they will probably get better at some point, especially if help is available
- You/they cannot, however, “just snap out of it”; illness doesn’t work that way
- Medication might help (it also might not)
Do what you can, how you can, when you can
Everyone knows the advice to exercise as a remedy for depression, and indeed, exercise helps many. Unfortunately, it’s not always that easy.
Did you ever see the 80s kids’ movie “The Neverending Story”? There’s a scene in which the young hero Atreyu must traverse the “Swamp of Sadness”, and while he has a magical talisman that protects him, his beloved horse Artax is not so lucky; he slows down, and eventually stops still, sinking slowly into the swamp. Atreyu pulls at him and begs him to keep going, but—despite being many times bigger and stronger than Atreyu, the horse just sinks into the swamp, literally drowning in despair.
See the scene: The Neverending Story movie clip – Artax and the Swamp of Sadness (1984)
Wow, they really don’t make kids’ movies like they used to, do they?
But, depression is very much like that, and advice “exercise to feel less depressed!” falls short of actually being helpful, when one is too depressed to do it.
If you’re in the position of supporting someone who’s depressed, the best tool in your toolbox will be not “here’s why you should do this” (they don’t care; not because they’re an uncaring person by nature, but because they are physiologically impeded from caring about themself at this time), but rather:
“please do this with me”
The reason this has a better chance of working is because the depressed person will in all likelihood be unable to care enough to raise and/or maintain an objection, and while they can’t remember why they should care about themself, they’re more likely to remember that they should care about you, and so will go with your want/need more easily than with their own. It’s not a magic bullet, but it’s worth a shot.
What if I’m the depressed person, though?
Honestly, the same, if there’s someone around you that you do care about; do what you can to look after you, for them, if that means you can find some extra motivation.
But I’m all alone… what now?
Firstly, you don’t have to be alone. There are free services that you can access, for example:
- US: https://nami.org/help
- Canada: https://www.wellnesstogether.ca/en-CA
- UK: https://www.samaritans.org/
…which varyingly offer advice, free phone services, webchats, and the like.
But also, there are ways you can look after yourself a little bit; do the things you’d advise someone else to do, even if you’re sure they won’t work:
- Take a little walk around the block
- Put the lights on when you’re not sleeping
- For that matter, get out of bed when you’re not sleeping. Literally lie on the floor if necessary, but change your location.
- Change your bedding, or at least your clothes
- If changing the bedding is too much, change just the pillowcase
- If changing your clothes is too much, change just one item of clothing
- Drink some water; it won’t magically cure you, but you’ll be in slightly better order
- On the topic of water, splash some on your face, if showering/bathing is too much right now
- Do something creative (that’s not self-harm). You may scoff at the notion of “art therapy” helping, but this is a way to get at least some of the lights on in areas of your brain that are a little dark right now. Worst case scenario is it’ll be a distraction from your problems, so give it a try.
- Find a connection to community—whatever that means to you—even if you don’t feel you can join it right now. Discover that there are people out there who would welcome you if you were able to go join them. Maybe one day you will!
- Hiding from the world? That’s probably not healthy, but while you’re hiding, take the time to read those books (write those books, if you’re so inclined), learn that new language, take up chess, take up baking, whatever. If you can find something that means anything to you, go with that for now, ride that wave. Motivation’s hard to come by during depression and you might let many things slide; you might as well get something out of this period if you can.
If you’re not depressed right now but you know you’re predisposed to such / can slip that way?
Write yourself instructions now. Copy the above list if you like.
Most of all: have a “things to do when I don’t feel like doing anything” list.
If you only take one piece of advice from today’s newsletter, let that one be it!
