❝I’m a 67- year old yoga teacher and runner. A lifelong runner, I started long distance running when I was 58. One of my friends loves rucking? I recently bought a rucking vest. Your thoughts? Any risks?
As a perk of my yoga instructor job I get cryotherapy, red light therapy, infrared sauna, and Normatec boots for a nominal fee. Even though they are almost free, I don’t take advantage of them as I can’t find evidence of their value and don’t want to waste my time. Do you recommend any of them?❞
On rucking and rucking vests
First, for any unfamiliar, this is about walking/running/exercising in general, with a weighted backpack or weight vest.
As for whether this is beneficial, it depends on your goals. Once upon a very long time ago when this writer was a soldier, it was vitally important to for me be able to [fall from the sky and then] run about 2km carrying a certain (hefty) amount of weight and still be able to fight at the other end of it, or else I would die. Thus, between deployments, I’d often carry a sturdy rucksack with concrete slabs in it, to keep myself accustomed to that burden (funny story: someone once tried to steal that when I had put it down while doing something—the would-be thief fell over instantly and then ran away empty-handed). And, here’s the thing: this kind of training did for me what I needed it to do for me. As a 67-year-old yoga teacher, your needs are probably very different.
A common reason to use weight vests is in an effort against osteoporosis, but the evidence is lacking (or very weak, at best), as we wrote about a while back:
Weight Vests Against Osteoporosis: Do They Really Build Bone?
With regard to risks… Let’s put it this way: my old regiment, in addition to the usual soldierly problems like hearing damage and PTSD, has quite a reputation for producing veterans with spinal compression injuries. And that’s entirely because of the whole “running with a large amount of weight strapped to us” thing. So, you probably don’t want that.
If you are going to do that though, then:
- a weight best is a lot better than a backpack (better distribution of weight)
- start with low weight and work up, and don’t push your limits
We’re not the boss of you, so by all means do as you see fit, but unless there’s a special reason why being able to run with a heavy weight is important to you, then running with a light weight is already more than good enough.
About those job perks
Again, of course, it depends on what you hope to get out of them, but in some cases there is a lot of evidence for benefit.
On cryotherapy: Ice Baths: To Dip Or Not To Dip? ← there are definite benefits for most people!
On red light therapy: Red Light, Go! Casting Yourself In A Healthier Light ← there are some caveats re people who should not do this or at least should be very wary, but for most people, this does a lot of good, and is very well-evidenced to be beneficial
On infrared saunas: we’re unaware of any special evidence in favor of these. However, traditional saunas have plenty of well-evidenced benefits: Saunas: Health Benefits (& Caveats)
On Normatec boots: for the unfamiliar, this is a brand name for compression technology. Again, it depends on what you want to get out of it, though. If you are in good health, then what it’s generally being advertised for is to prevent/reduce exercise-induced muscle damage caused by the stress that endurance training can place on skeletal muscle. Just one problem—it doesn’t seem to work:
❝Athletes attempt to aid their recovery in various ways, one of which is through compression. Dynamic compression consists of intermittent pneumatic compression (IPC) devices, such as the NormaTec Recovery System and Recovery Pump
Clinical Question: What are the effects of IPC on the reduction of Exercise-Induced Muscle Damage (EIMD) in endurance athletes following prolonged exercise? Summary of Key Findings: The current literature was searched to identify the effects of IPC, and 3 studies were selected: 2 randomized controlled trials and 1 randomized cross-over study. Two studies investigated the effect of IPC on delayed onset muscle soreness and plasma creatine kinase in ultramarathoners. The other looked at the impact of IPC on delayed onset muscle soreness in marathoners, ultramarathoners, triathletes, and cyclists.
All studies concluded IPC was not an effective means of improving the reduction of EIMD in endurance-trained athletes.❞
However! If you have lipedema and/or lymphedema and want to manage that, then compression gear may help:
Take care!

“Why Does It Hurt When I Have Sex?” (And What To Do About 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.
This is one that affects mostly women, with 43% of American women reporting such issues at some point. There’s a distribution curve to this, with higher incidence in younger and older women; younger while first figuring things out, and older with menopause-related body changes. But, it can happen at any time (and often not for obvious reasons!), so here’s what OB/GYN Dr. Jennifer Lincoln advises:
Many possibilities, but easily narrowed down
Common causes include:
- vaginal dryness, which itself can have many causes (half of which are “low estrogen levels” for various different reasons)
- muscular issues, which can be in response to anxiety, pain, and occur as a result of pelvic floor muscle tightening
- vulvar issues, ranging from skin disorders (e.g. lichen sclerosis or lichen planus) to nerve disorders (e.g. vestibulitis or vestibulodynia)
- uterine issues, including endometriosis, fibroids, or scar tissue if you had a surgery
- infections, of the STI variety, but bear in mind that some STIs such as herpes do not necessarily require direct sexual contact per se, and yeast infections definitely don’t. Some STIs are more serious than others, so getting things checked out is a good idea (don’t worry, clinics are discreet about this sort of thing)
- bowel issues, notwithstanding that we have been talking about vaginal sex here, it can’t be happy if its anatomical neighbors aren’t happy—so things like IBS, Crohn’s, or even just constipation, aren’t irrelevant
- trauma, of various kinds, affecting sexual experiences
That’s a lot of possibilities, so if there’s not something standing out as “yes, now that you mention it, it’s obviously that”, Dr. Lincoln recommends a full health evaluation and examination of medical history, as well as a targeted physical exam. That may not be fun, but at least, once it’s done, it’s done.
Treatments vary depending on the cause, of course, and there are many kinds of physical and psychological therapies, as well as surgeries for the uterine issues we mentioned.
Happily, many of the above things can be addressed with simpler and less invasive methods, including learning more about the relevant anatomy and physiology and how to use it (be not ashamed; most people never got meaningful education about this!)*, vulvar skin care (“gentle” is the watchword here), the difference a good lube can make, and estrogen supplementation—which if you’re not up for general HRT, can be a topical estrogen cream that alleviates sexual function issues without raising blood serum estradiol levels.
*10almonds tip: check out the recommended book “Come As You Are” in our links below; it has 400 pages of stuff most people never knew about anatomy and physiology down there; you can thank us later!

Vaginal Probiotics: What Does The Science Say?
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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 😎
❝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.
See also: Make Friends With Your Gut (You Can Thank Us Later)
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:
How To Avoid Urinary Tract Infections (UTIs)
One other option
Finally, unless you have a “very good friend” you have a pressing urge to swap germs with, you might want to leave this one to the scientists, but we share this paper just for interest:
Lastly…
Going back to oral supplementation, if you’d like to try that then check out this for further notes on what, why, how, etc:

Eat Real Food and Love It – by Kari McCloskey
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.
Half the battle of healthy eating is enjoying it—because once you do, it’s no longer a battle!
So that’s what this book focuses on. The author, a Registered Nutritionist, does indeed dispense nutritional advice, as you might expect, but also bids us pay attention to what nature’s foods do for us, and notice what less healthy foods take from us. She goes through these category by category, quite comprehensively, before moving on to the more “active” parts of the book.
There’s a lot about training our senses, and about taking a holistic approach to eating, as well as renewing not just our relationship with food, but also various other parts of our life that are inextricably linked to it (from sleep and exercise, to social considerations, and medical issues that healthier eating will help us to avoid or at least tame).
The style is… Joyful. Much like this reviewer, the author loves food, and it shows. She also (again much like this reviewer) cares deeply about the impact food has on her, and (for a third time: like this reviewer!) wants to share that joy and care with the reader. The priority is readability and helpfulness; scientific references are still provided wherever appropriate, though.
Bottom line: if you’d like to improve your eating but it seems like a chore, this book can help turn it into an excitingly enjoyable journey instead.

The Tiniest Seeds With The Most Value
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.
If You’re Not Taking Chia, You’re Missing Out
Last Tuesday, we wrote about nutritional psychiatry, and the benefits of eating for one’s mental health.
You can check out Dr. Uma Naidoo’s to-dos, here:
The 6 Pillars Of Nutritional Psychiatry
In response, one of our subscribers wrote to mention:
❝Really interesting….just put chia seeds in my diet love them……taking the Drs advice.❞
~ Cindy, 10almonds subscriber
And then! On Friday, our tip at the top of the newsletter was:
Not sure how to incorporate chia seeds into your diet? It’s easier to want the benefits of their many brain-healthy (and otherwise-healthy, too) nutrients, than it is to know what to do with them necessarily, and not everyone enjoys seeds as a snack. So…
When you cook rice, throw in a tablespoon of chia seeds too. The cooking process will soften them and they won’t be texturally any different than the rice, but the nutrients will be all there.
They can also be thrown in with lentils, in the same fashion! Or oatmeal, when cooking it or making overnight oats.
We’ll be honest, it was Cindy’s comment that prompted us to suggest it. But wait! There was more to come in response:
❝You had a teaser ..on Chia seed.would of liked a article on the benefits . I’ve just discovered Chia seeds…❞
~ Cindy, 10almonds subscriber
So, Cindy, this one’s for you:
Nutritional powerhouse
First things first, these tiny seeds have a lot of nutrients. There are not many more nutrient-dense foods than this (there’s a kind of seaweed that might be a contender; we’ll have to do some research and get back to you).
Check them out:
USDA Nutritional Factsheet: Chia Seeds
So much protein and healthy fat, so many vitamins and minerals, and so many miscellaneous other micronutrients that we’d be here all day to list them (which is why we linked the above factsheet instead).
Antioxidants in abundance
These deserve a special mention, because they include quercetin which we’ve written about previously:
Fight Inflammation & Protect Your Brain, With Quercetin
…as well as quite a collection of others (including chlorogenic acid and caffeic acid, which may sound alarming but are great for lowering your blood pressure and against inflammation, respectively):
- The effect of chlorogenic acid on blood pressure: a systematic review and meta-analysis of randomized clinical trials
- Synthesis, preliminary bioevaluation and computational analysis of caffeic acid analogues
There are others too, with cardioprotective effects, liver-healthy effects, and anticancer properties:
Nutritional and therapeutic perspectives of Chia (Salvia hispanica L.): a review
Good for the heart and blood
Check it out:
- Chia flour supplementation reduces blood pressure in hypertensive subjects
- Chia seed (Salvia hispanica L.) supplementation to the diet of adults with type 2 diabetes improved systolic blood pressure: A randomized controlled trial
Oh, and about diabetes? There’s more, this time pertaining to reducing after-dinner blood sugars (or “postpranidial glycemia”, in sciencese):
- Reduction in postprandial glucose excursion and prolongation of satiety: possible explanation of the long-term effects of whole grain Salba (Salvia Hispanica L.)
- Effect of whole and ground Salba seeds (Salvia Hispanica L.) on postprandial glycemia in healthy volunteers: a randomized controlled, dose-response trial
Good for the brain
Regular 10almonds readers will know that “what’s good for the blood, is good for the brain” is a very good rule of thumb already, but their highomega-3 content makes them especially so:

Knee Pain Won’t Get Better Unless You Fix This First
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.
Most knee pain is mechanical, caused by excessive stress or strain on specific parts of the knee joint. However, it’s weak glutes that are often the root cause of excess knee strain, because when glutes are weak, they fail to keep the pelvis level and legs aligned, leading to improper knee movement.
The seat of the problem
Weak glutes cause the pelvis to drop and the thigh bone to roll inwards (called “valgus knee”). This misalignment creates shearing forces and excessive pressure on different parts of the knee. However, it can usually be fixed, and the following exercises are recommended:
- Seated band abductions: use a resistance band around the thighs while seated. Push your knees apart, and hold for a few seconds.
- Glute bridge with resistance band: lie on your back with your feet flat and a resistance band around your thighs. Push your hips up into a bridge position, then press your knees outward against the band.
- Clamshell exercise: lie on your side, with your knees bent at 90°. Keep your body slightly tilted forward, then lift the top knee while keeping your heels together.
- Hip abductions (lateral leg raises): lie on your side, keeping your legs straight. Lift the top leg slightly backward and upward, leading with your heel.
- Standing hip abductions: stand upright, using a wall for support. Lift one leg sideways and slightly backward while keeping your spine straight. Unlike the other exercises, this one has the benefit of being doable almost anywhere.

The Lupus Solution – by Dr. Tiffany Caplan & Dr. Brent Caplan
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.
Lupus is not fun, and this book sets out to make it easier.
Starting off by explaining the basics of autoimmunity and how lupus works, the authors go on the address the triggers of lupus and how to avoid them—which if you’ve been suffering from lupus for a while, you probably know this part already, but it’s as well to give them a look over just in case you missed something.
The real value of the book though comes in the 8 chapters of the section “Tools & Therapies” which are mostly lifestyle adjustments though there are additionally some pharmaceutical approaches that can also help, and they are explained too. And no, it’s not just “reduce inflammation” (but yes, also that); rather, a whole array of things are examined that often aren’t thought of as related to lupus, but in fact can have a big impact.
The style is to-the-point and informational, and formatted for ease of reading. It doesn’t convey more hard science than necessary, but it does have a fair bibliography at the back.
It’s a short book, weighing in at 182 pages. If you want something more comprehensive, check out our review of The Lupus Encyclopedia, which is 848 pages of information-dense text and diagrams.
Bottom line: if you have lupus and would like fewer symptoms, this book can help you with that quite a bit without getting so technical as the aforementioned encyclopedia.
