Back To Back
When people think about looking after their back, often thought does not go much further than sitting with good posture, and perhaps even standing with good posture. And those things are important, but:
1) People’s efforts to have good posture often result in overcorrecting creating an anterior pelvic tilt that causes lower back problems.
Quick tip: if you’re sticking your butt out, you’re doing it wrong (no matter how great your butt is). Instead, to find the correct posture, go up on your tip-toes for a moment, then imagine a plumb-line down the center of your body, thus perpendicular to the floor, going all the way down to the ground. Now, slowly return your heels to the ground, but as you do so, keep your spine aligned to the plumb-line, so you’re not moving backwards as you drop, just directly down. This will land you in perfect posture.
Unless you have scoliosis. In which case, it’ll get you as close to good posture as is likely attainable from any quick tip.
2) There’s a lot more to looking after our back than just good posture!
Here are 5 other important things to do:
Be strong
Do strength-training for your back. How to do that is beyond the scope of today’s feature, but there are many good guides and also personal trainers that can be found.
Start off easy and work up, but do start. The stronger your back is, the less likely a momentary lapse in concentration is to throw out your back because you picked something up with imperfect form.

Stretch intentionally
Many back injuries occur as a result of stretching and/or twisting awkwardly, so if you ensure your basic mobility and range of motion is good, the less likely it is that unthinkingly twisting around 270° to see where that wasp was going will slip a disk.
The more you stretch intentionally (carefully, please), the more you will be able to stretch unintentionally without injury.

Stand when you can, walk when you can
We humans have outrun our evolution in a lot of ways, and/but one thing our bodies are definitely not well-adapted for is sitting. Unless we are sitting in a low squat the way you might often see an orang-utan sitting, sitting is not a good way of being for us. Even sitting seiza-style or cross-legged is passable for a short while, not for too long.
So, while there sure are times we need to sit (especially if you’re driving!) minimizing those times is ideal. There are a lot of activities that are traditionally done sitting, where there’s no need for it to be so. For example, your writer here sits for the day’s main meal, but takes any smaller meal standing (and when guests visit for a coffee or such, I’ll offer them the couch while I myself prop up the fireplace). Standing desks are also great if you spend a lot of time at the computer for any reason.

Rest when you need to
You can’t stand all the time! But know this: if you want to rest your legs, lying down is a lot better for your back (and internal organs) than sitting.
Taking a 5 minute break lying on your couch, or bed, or floor, is a perfectly good option and only social convention says otherwise.
If you want a compromise option, though? A recliner chair, in the reclined position, is a better for your back than being scrunched up in the Economy Class Flight position.

Kill pain before it kills you
Painkillers aren’t great for the health per se, but pain (or rather, our bodily responses to such) can be worse. Half the time, when it comes to musculoskeletal problems, things get a lot worse a lot more quickly because of how we overcompensate due to the pain. So, take your pain seriously, and remember, the right amount of pain is zero.

Is Fast Food Really All That Bad?
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.
Yes, yes it is. However, most people misunderstand the nature of its badness, which is what causes problems. The biggest problem is not the acute effects of one afternoon’s burger and fries; the biggest problem is the gradual slide into regularly eating junk food, and the long-term effects of that habit as our body changes to accommodate it (of which, people tend to focus on subcutaneous fat gain as it’s usually the most visible, but that’s really the least of our problems).
Cumulative effects
There are, of course, immediate negative effects too, and they’re not without cause for concern. Because of the composition of most junk food, it will almost by definition result in immediate blood sugar spikes, rising insulin levels, and a feeling of fatigue not long afterwards.
- Within a week of regularly consuming junk food, gut bacteria will change, resulting in moderate cravings, as well as a tendency towards depression and anxiety. Mood swings are likely, as are the gastrointestinal woes associated with any gut microbiota change.
- Within two weeks, those effects will be greater, the cravings will increase, energy levels will plummet, and likely skin issues may start to show up (our skin mostly works on a 3-week replacement cycle; some things can show up in the skin more quickly or slowly than that, though).
- Within three weeks, the rest of our blood metrics (e.g. beyond blood sugar imbalances) will start to stray from safe zones. Increased LDL, decreased HDL, and the beginnings of higher cardiovascular disease risk and diabetes risk.
- Within a month, we will likely see the onset of non-alcoholic fatty liver disease, and chronic inflammation sets in, raising the risk of a lot of other diseases, especially immune disorders and cancer.
If that seems drastic, along the lines of “eat junk food for a month and get cancer”, well, it’s an elevated risk, not a scheduled diagnosis, but the body is constantly rebuilding itself, for better or for worse, and if we sabotage its efforts by consuming a poor diet, then it will be for worse.
The good news is: this works both ways, and we can get our body back on track in fairly short order too, by enjoying a healthier diet; our body will be thrilled to start repairing itself. And of course, all these effects, good and bad, are proportional to how well or badly we eat. There’s a difference between doing a “Supersize Me” month-long 100% junk food diet, and “merely” getting a junk food breakfast each day and eating healthily later.
In short, if your diet is only moderately bad, then you will only be moderately unwell.

Could Just Two Hours Sleep Per Day Be Enough?

Polyphasic Sleep… Super-Schedule Or An Idea Best Put To Rest?
What is it?
Let’s start by defining some terms:
- Monophasic sleep—sleeping in one “chunk” per day. For example, a good night’s “normal” sleep.
- Biphasic sleep—sleeping in two “chunks” per day. Typically, a shorter night’s sleep, with a nap usually around the middle of the day / early afternoon.
- Polyphasic sleep—sleeping in two or more “chunks per day”. Some people do this in order to have more hours awake per day, to do things. The idea is that sleeping this way is more efficient, and one can get enough rest in less time. The most popular schedules used are:
- The Überman schedule—six evenly-spaced 20-minute naps, one every four hours, throughout the 24-hour day. The name is a semi-anglicized version of the German word Übermensch, “Superman”.
- The Everyman schedule—a less extreme schedule, that has a three-hours “long sleep” during the night, and three evenly-spaced 20-minute naps during the day, for a total of 4 hours sleep.
There are other schedules, but we’ll focus on the most popular ones here.
Want to learn about the others? Visit: Polyphasic.Net (a website by and for polyphasic sleep enthusiasts)
Some people have pointed to evidence that suggests humans are naturally polyphasic sleepers, and that it is only modern lifestyles that have forced us to be (mostly) monophasic.
There is at least some evidence to suggest that when environmental light/dark conditions are changed (because of extreme seasonal variation at the poles, or, as in this case, because of artificial changes as part of a sleep science experiment), we adjust our sleeping patterns accordingly.
The counterpoint, of course, is that perhaps when at the mercy of long days/nights at the poles, or no air-conditioning to deal with the heat of the day in the tropics, that perhaps we were forced to be polyphasic, and now, with modern technology and greater control, we are free to be monophasic.
Either way, there are plenty of people who take up the practice of polyphasic sleep.
Ok, But… Why?
The main motivation for trying polyphasic sleep is simply to have more hours in the day! It’s exciting, the prospect of having 22 hours per day to be so productive and still have time over for leisure.
A secondary motivation for trying polyphasic sleep is that when the brain is sleep-deprived, it will prioritize REM sleep. Here’s where the Überman schedule becomes perhaps most interesting:
The six evenly-spaced naps of the Überman schedule are each 20 minutes long. This corresponds to the approximate length of a normal REM cycle.
Consequently, when your head hits the pillow, you’ll immediately begin dreaming, and at the end of your dream, the alarm will go off.
Waking up at the end of a dream, when one hasn’t yet entered a non-REM phase of sleep, will make you more likely to remember it. Similarly, going straight into REM sleep will make you more likely to be aware of it, thus, lucid dreaming.
Read: Sleep fragmentation and lucid dreaming (actually a very interesting and informative lucid dreaming study even if you don’t want to take up polyphasic sleep)
Six 20-minute lucid-dreaming sessions per day?! While awake for the other 22 hours?! That’s… 24 hours per day of wakefulness to use as you please! What sorcery is this?
Hence, it has quite an understandable appeal.
Next Question: Does it work?
Can we get by without the other (non-REM) kinds of sleep?
According to Überman cycle enthusiasts: Yes! The body and brain will adapt.
According to sleep scientists: No! The non-REM slow-wave phases of sleep are essential
Read: Adverse impact of polyphasic sleep patterns in humans—Report of the National Sleep Foundation sleep timing and variability consensus panel
(if you want to know just how bad it is… the top-listed “similar article” is entitled “Suicidal Ideation”)
But what about, for example, the Everman schedule? Three hours at night is enough for some non-REM sleep, right?
It is, and so it’s not as quickly deleterious to the health as the Überman schedule. But, unless you are blessed with rare genes that allow you to operate comfortably on 4 hours per day (you’ll know already if that describes you, without having to run any experiment), it’s still bad.
Adults typically need 7–9 hours of sleep per night, and if you don’t get it, you’ll accumulate a sleep debt. And, importantly:
When you accumulate sleep debt, you are borrowing time at a very high rate of interest!
And, at risk of laboring the metaphor, but this is important too:
Not only will you have to pay it back soon (with interest), you will be hounded by the debt collection agents—decreased cognitive ability and decreased physical ability—until you pay up.
In summary:
- Polyphasic sleep is really very tempting
- It will give you more hours per day (for a while)
- It will give the promised lucid dreaming benefits (which is great until you start micronapping between naps, this is effectively a mini psychotic break from reality lasting split seconds each—can be deadly if behind the wheel of a car, for instance!)
- It is unequivocally bad for the health and we do not recommend it
Bottom line:
Some of the claimed benefits are real, but are incredibly short-term, unsustainable, and come at a cost that’s far too high. We get why it’s tempting, but ultimately, it’s self-sabotage.
(Sadly! We really wanted it to work, too…)

In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝As far as specific brands of vitamin…some are good some not. I don’t like being told what buy but I guess I want to know which are effective. Could there be some brands recognized as good given to us?❞
The most reliable brands are generally those with the most transparency:
- They tell you what is in the supplement; not just the active ingredient(s), with doses, but also any buffers etc.
- They tell you, in the case of ingredients that can have various different sources, what the source is.
- They are, ideally, well-certified and independently tested.
Our previous sponsor Ora is a good example of a company that does this.
Additionally, in terms of bioavailability, generally speaking the order of preference goes liquid > capsule/softgel > tablet, so that’s something to look out for, too.
Note: “liquid” includes powders that are ingested when dissolved/suspended in water, and also includes tablets that become a liquid when dissolved/dispersed in water and ingested that way.

Vaginal Probiotics: What Does The Science Say?

❝Is there any merit to vaginal probiotics?❞
What a fun question! First let’s break it down, as this could mean two different things:
- Probiotics, which you consume, using your mouth, which are marketed as benefiting vaginal health
- Probiotics taken as a vaginal pessary/suppository, to act directly there
The former has limited evidence for it, but generally speaking, improving one’s gut health improves all other areas of health, so it’s not surprising if it helps this too.
See for example:
Some notes:
- candidal vaginitis means a yeast infection causing vaginal inflammation
- bacterial vaginosis means a vaginal bacterial imbalance (generally also featuring vaginal inflammation, though it can be asymptomatic)
In the latter case, the “imbalance” in question is usually a shortage of Lactobacillus sp. (that is to say, the diverse species of the Lactobacillus genus) resulting in an overgrowth of other kinds of bacteria, which in turn results in changing the vaginal microbiome to make it warmer and more acidic than it should be.
While a healthy vagina shouldn’t smell of roses, it shouldn’t smell fishy either; if it does, that’s a sign of bacterial vaginosis.
What it’s supposed to be like: slightly bitter, slightly salty, distinctly umami, along with a cocktail of personal pheromones (and if menstruating or otherwise* vaginally bleeding, then of course add: iron/”metallic”). The pheromones will also reflect any hormonal changes, but should never make anything smell bad, just different.
*e.g. due to PCOS, fibroids, etc. Note that in the case of PCOS, it may also smell a little different (if it does, then usually: a little more musky), due to often different hormone levels. Again: it still shouldn’t smell bad, though, just different.
In the above-linked study, taking more live Lactobacillus acidophilus (in yogurt, eating it, with their mouths) improved levels of L. acidophilus in the vagina. While the study authors concluded “this ingestion of yogurt may have reduced episodes of bacterial vaginosis”, which is rather a weak claim, it can be argued that it merely improving the levels of L. acidophilus in the vagina was already a win.
That was a small (n=42, and only 7 followed through to completion) and old (1996) study, and it bears mentioning that most of the studies into this seem to be small and old, but conclude similarly with weakly positive statements.
However, it does make a difference what kind of Lactobacillus is used, for example in this next study…
- L. fermentum RC-14 worked well (90% success rate)
- L. rhamnosus GR-1 worked somewhat (40% success rate)
- L. rhamnosus GG did not work (0% success rate)
So, diversity is key, and getting a wide range of Lactobacillus sp. seems to be a safe bet.
Short version: enjoying probiotics as part of your diet probably improves vaginal health, just like it improves pretty much everything else.

You would think that this would mean that taking probiotics as a vaginal pessary/suppository would be even better, but the results are weaker, as in this study, which produced temporary improvements in about half the study group, with only 3 out of 28 being free of bacterial vaginosis the next month:
Treatment of bacterial vaginosis with lactobacilli
This study got better results, with a 61% success rate:
Important note
Do note that this last category, involving topical treatments (i.e., manually introducing Lactobacillus sp. to the vagina) were all in cases of pre-existing bacterial vaginosis, not as a prophylactic and/or general health-improving thing.
If your vagina seems happy right now, then do not mess with its happy bacterial balance!
And at all times (regardless of whether it seems happy right now or not): do not douche (it does not need it and will not benefit from it; the vagina is self-cleaning*) as this will wash out many of your Lactobacilli and will do absolutely nothing against any Candida there (C. albicans being a rooted fungus, whereas Lactobacillus is a sausage-shaped bacterium with many tiny appendages but no actual ability to stay put), so Candida will flourish in the Lactobacillus’s absence.
*by the vagina, we are referring to the vaginal canal. The vulva—the outside part consisting of the two pairs of labia, the glans clitoris, and clitoral hood—are not self-cleaning, and should just be washed gently per your normal bath/shower routine; that’s perfectly fine and good.
And definitely don’t put any “cleansing” toiletries inside the vagina (or any toiletries at all, for that matter), even if they are sold and marketed for that purpose; they will not help and they will harm.
Also, due to their neighborliness, messing up the microbiome inside the vagina is a common way to also get Candida inside the urethra:

Peripheral Neuropathy: How To Avoid It, Manage It, Treat It
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.
Peripheral neuropathy (and what can be done about it)
Peripheral neuropathy is nerve damage, usually of the extremities. It can be caused by such things as:
- Diabetes
- Alcoholism
- Infection
- Injury
The manifestations can be different:
- In the case of diabetes, it’s also called diabetic neuropathy, and almost always affects the feet first.
- In the case of alcoholism, it is more generalized, but tends towards affecting the extremities first.
- In the case of infection, a lot depends on the nature of the infection and the body’s response.
- In the case of injury, it’ll naturally be the injured part, or a little “downstream” of the injured part.
- This could be the case of a single traumatic injury (e.g. hand got trapped in a slammed door)
This could be the case of a repetitive injury (carpal tunnel syndrome is a kind of peripheral neuropathy, and is usually caused by consistent misalignment of the carpal tunnel, the aperture through which a bundle of nerves make their way from the forearm to the hand)
Prevention is better than cure
If you already have peripheral neuropathy, don’t worry, we’ll get to that. But, if you can, prevention is better than cure. This means:
- Diabetes: if you can, avoid. This may seem like no-brainer advice, but it’s often something people don’t think about until hitting a pre-diabetic stage. Obviously, if you are Type 1 Diabetic, you don’t have this luxury. But in any case, whatever your current status, take care of your blood sugars as best you can, so that your blood can take care of you (and your nerves) in turn. You might want to check out our previous main feature about this:
- Alcoholism: obviously avoid, if you can. You might like this previous edition of 10almonds addressing this:
- Infection: this is so varied that one-liner advice is really just “try to look after your immune health”.
- We’ll do a main feature on this soon!
- Injury: obviously, try to be careful. But that goes for the more insidious version too! For example, if you spend a lot of time at your computer, consider an ergonomic mouse and keyboard.
- There are many kinds available, so read reviews, but here’s an example product on Amazon
Writer’s note: as you might guess, I spend a lot of time at my computer, and a lot of that time, writing. I additionally spend a lot of time reading. I also have assorted old injuries from my more exciting life long ago. Because of this, it’s been an investment in my health to have:
A standing desk
A vertical ergonomic mouse
An ergonomic split keyboard
A Kindle*
*Far lighter and more ergonomic than paper books. Don’t get me wrong, I’m writing to you from a room that also contains about a thousand paper books and I dearly love those too, but more often than not, I read on my e-reader for comfort and ease.
If you already have peripheral neuropathy
Most advice popular on the Internet is just about pain management, but what if we want to treat the cause rather than the symptom?
Let’s look at the things commonly suggested: try ice, try heat, try acupuncture, try spicy rubs (from brand names like Tiger Balm, to home-made chilli ointments), try meditation, try a warm bath, try massage.
And, all of these are good options; do you see what they have in common?
It’s about blood flow. And that’s why they can help even in the case of peripheral neuropathy that’s not painful (it can also manifest as numbness, and/or tingling sensations).
By getting the blood flowing nicely through the affected body part, the blood can nourish the nerves and help them function correctly. This is, in effect, the opposite of what the causes of peripheral neuropathy do.
But also don’t forget: rest
- Put your feet up (literally! But we’re talking horizontal here, not elevated past the height of your heart)
- Rest that weary wrist that has carpal tunnel syndrome (again, resting it flat, so your hand position is aligned with your forearm, so the nerves between are not kinked)
- Use a brace if necessary to help the affected part stay aligned correctly
- You can get made-for-purpose wrist and ankle braces—you can also get versions that are made for administering hot/cold therapy, too. That’s just an example product linked that we can recommend; by all means read reviews and choose for yourself, though. Try them and see what helps.
One more top tip
We did a feature not long back on lion’s mane mushroom, and it’s single most well-established, well-researched, well-evidenced, completely uncontested benefit is that it aids peripheral neurogenesis, that is to say, the regrowth and healing of the peripheral nervous system.

Honey vs Maple Syrup – 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 honey to maple syrup, we picked the honey.
Why?
It was very close, as both have small advantages:
• Honey has some medicinal properties (and depending on type, may contain an antihistamine)
• Maple syrup is a good source of manganese, as well as low-but-present amounts of other mineralsHowever, you wouldn’t want to eat enough maple syrup to rely on it as a source of those minerals, and honey has the lower GI (average 46 vs 54; for comparison, refined sugar is 65), which works well as a tie-breaker.
(If GI’s very important to you, though, the easy winner here would be agave syrup if we let it compete, with its GI of 15)
