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
❝I’ve read that air pollution has a negative effect on sleep quality and duration. Since I live next to a busy road, I was wondering whether I should invest in an air purifier. What are 10Almonds’s views?❞
Going straight to the science, there are two questions here:
- Does air pollution negatively affect sleep quality and duration?
- Does the use of an air purify actually improve the air quality in the way(s) necessary to make a difference?
We thought we’d have to tackle these questions separately, but we did find one study that addressed your question directly. It was a small study (n=30 if you believe the abstract; n=29 if you read the paper itself—one person dropped out); the results were modest but clear:
❝The purifier filter was associated with increased total sleep time for an average of 12 min per night, and increased total time in bed for an average of 19 min per night relative to the placebo.
There were several sleep and mood outcomes for which no changes were observed, and time awake after sleep onset was higher for the purifier filter. Air quality was better during the high-efficiency particulate air filter condition.
These findings offer positive indications that environmental interventions that improve air quality can have benefits for sleep outcomes in healthy populations who are not exhibiting clinical sleep disturbances.❞
In the above-linked paper’s introduction, it does establish the deleterious effect of air pollution on a wide variety of health metrics, including sleep, this latter evidenced per Caddick et al. (2018): A review of the environmental parameters necessary for an optimal sleep environment
Now, you may be wondering: is an extra 12 minutes per night worth it?
That’s your choice to make, but we would argue that it is. We can make many choices in our lives that affect our health slightly for the better or the worse. If we make a stack of choices in a particular direction, the effects will also stack, if not outright compound.
So in the case of sleep, it might be (arbitrary numbers for the sake of illustration):
- Get good exercise earlier in the day (+3%)
- Get good food earlier in the day (+2.5%)
- Practice mindfulness/meditation before bed (+2.5%)
- Have a nice dark room (+5%)
- Have fresh bedding (+2.5%)
- Have an air purifier running (+3%)
Now, those numbers are, as we said, arbitrary*, but remember that percentages don’t add up; they compound. So that “+3%” starts being a lot more meaningful than if it were just by itself.
*Confession: the figure of 3% for the air purifier wasn’t entirely arbitrary; it was based on 100(12/405) = 80/27 ≈ 3, wherein the 405 figure was an approximation of the average total time (in minutes) spent sleeping with placebo, based on a peep at their results graph. There are several ways the average could be reasonably calculated, but 6h45 (i.e., 405 minutes) was an approximate average of those reasonable approximate averages.
So, 12 minutes is a 3% improvement on that.
Don’t have an air purifier and want one?
We don’t sell them, but here’s an example on Amazon, for your convenience
Take care!

9 Reasons To Avoid Mobility Training
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.
Why might someone not want to do mobility training? Here are some important reasons:
Make an informed choice
Here’s Liv’s hit-list of reasons to skip mobility training:
- Poor Circulation: Avoid mobility training if you don’t want to improve or maintain good blood circulation, which aids muscle recovery and reduces soreness.
- Low Energy Levels: Mobility training increases oxygen flow to the brain and muscles, boosting energy. Skip it if you prefer feeling sluggish!
- Digestive Health: Stretches that rotate the torso aid digestion and relieve bloating. Definitely best to avoid it if you’re uninterested in improving digestive health.
- Joint Health: Mobility work stimulates synovial fluid production, reducing joint friction and promoting longevity. You can skip it if you don’t care about comfortable movement.
- Sleep Quality: Gentle stretching triggers relaxation, aiding restful sleep. Avoid it if you enjoy restless nights!
- Pain Tolerance: Stretching trains the nervous system to handle discomfort better. Skip it if you prefer suffering 🙂
- Headache Reduction: Mobility work relieves tension in the neck and shoulders, reducing the occurrence and severity of headaches. No need to do it if you’re fine with frequent headaches.
- Immune System Support: Mobility training boosts lymphatic circulation, aiding the immune system. Avoid it if you prefer your immune system to get exciting in a bad way.
- Stress Reduction: Mobility exercises release endorphins and lower cortisol levels, reducing stress. So, it is certainly best to skip it if you prefer feeling stressed and enjoy the many harmful symptoms of high cortisol levels!

Chicken or Fish – 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 chicken to fish, we picked the fish.
Why?
To understand the choice, we have to start a bit earlier on the decision tree. For most people most of the time, when it comes to a diet high in plants or high in animals, the plant-centric diet will generally be best:
Do We Need Animal Products To Be Healthy?
When it comes to animal meats, red meat is a fairly uncontroversial first thing to strike off the list:
…with pork and some other meats not being much better.
But chicken? Poultry in general appears to be quite health-neutral. The jury is out and the science has mixed results, but the data is leaning towards “it’s probably fine”.
See for example this huge (n=29,682) study:
this same paper shows that…
❝higher intake of processed meat, unprocessed red meat, or poultry, but not fish, was significantly associated with a small increased risk of incident CVD, whereas higher intake of processed meat or unprocessed red meat, but not poultry or fish, was significantly associated with a small increased risk of all-cause mortality❞
So, since poultry isn’t significantly increasing all-cause mortality, and fish isn’t significantly increasing all-cause mortality or cardiovascular disease, fish comes out as the hands-down (fins-down?) winner.
One more (this time, easy) choice to make, though!
While fish in general (please, not fried, though!) is generally considered quite healthy, there is a big difference (more than you might think, and for reasons that are quite alarming), between…

Escape From The Clutches Of Shame
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 written before about managing various emotions, including “negative” ones. We put that in “scare quotes” because they also all have positive aspects, that are just generally overshadowed by the fact that the emotions themselves are not pleasant. But for example…
We evolved our emotions, including the “negative” ones, for our own benefit as a species:
- Stress keeps us safe by making sure we take important situations seriously
- Anger keeps us safe by protecting us from threats
- Disgust keeps us safe by helping us to avoid things that might cause disease
- Anxiety keeps us safe by ensuring we don’t get complacent
- Guilt keeps us safe by ensuring we can function as a community
- Sadness keeps us safe by ensuring we value things that are important to us, and learn to become averse to losing them
- …and so on
You can read more about how to turn these off (or rather, at least pause them) when they’re misfiring and/or just plain not convenient, here:
While it’s generally considered good to process feelings instead of putting them aside, the fact is that sometimes we have to hold it together while we do something, such that we can later have an emotional breakdown at a convenient time and place, instead of the supermarket or bank or office or airport or while entertaining houseguests or… etc.
Today, though, we’re not putting things aside, for the most part (though we will get to that too).
We’ll be dealing with shame, which is closely linked to the guilt we mentioned in that list there.
See also: Reconsidering the Differences Between Shame and Guilt
Shame’s purpose
Shame’s purpose is to help us (as a community) avoid anti-social behavior for which we might be shamed, and thus exiled from the in-group. It helps us all function better together, which is how we thrive as a species.
Shame, therefore, is often assumed to be something we can (and possibly should) use to ensure that we (ourselves and/or others) “do the right thing”.
But there’s a catch…
Shame only works negatively
You may be thinking “well duh, it’s a negative emotion”, but this isn’t about negativity in the subjective sense, but rather, positive vs negative motivation:
- Positive motivation: motivation that encourages us to do a given thing
- Negative motivation: motivation that encourages us to specifically not do a given thing
Shame is only useful as a negative motivation, i.e., encouraging us to specifically not do a given thing.
Examples:
- You cannot (in any way that sticks, at least) shame somebody into doing more housework.
- You can, however, shame somebody out of drinking and driving.
This distinction matters a lot when it comes to how we are with our children, or with our employees (or those placed under us in a management structure), or with people who otherwise look to us as leaders.
It also matters when it comes to how we are with ourselves.
Here’s a paper about this, by the way, with assorted real-world examples:
The negative side of motivation: the role of shame
From those examples, we can see that attempts to shame someone (including oneself) into doing something positive will generally not only fail, they will actively backfire, and people (including oneself) will often perform worse than pre-shaming.
Looking inwards: healthy vs unhealthy shame
Alcoholics Anonymous and similar programs use a degree of pro-social shame to help members abstain from the the act being shamed.
Rather than the unhelpful shame of exiling a person from a group for doing a shameful thing, however, they take an approach of laying out the shame for all to see, feeling the worst of it and moving past it, which many report as being quite freeing emotionally while still [negatively] motivational to not use the substance in question in the future (and similar for activity-based addictions/compulsions, such as gambling, for example).
As such, if you are trying to avoid doing a thing, shame can be a useful motivator. So by all means, if it’s appropriate to your goals, tell your friends/family about how you are now quitting this or that (be it an addiction, or just something generally unhealthy that you’d like to strike off your regular consumption/activity list).
You will still be tempted! But the knowledge of the shame you would feel as a result will help keep you from straying into that temptation.
If you are trying to do a thing, however, (even something thought of in a negative frame, such as “lose weight”), then shame is not helpful and you will do best to set it aside.
You can shame yourself out of drinking sodas (if that’s your plan), but you can’t shame yourself into eating healthy meals. And even if your plan is just shaming yourself out of eating unhealthy food… Without a clear active positive replacement to focus on instead, all you’ll do there is give yourself an eating disorder. You’ll eat nothing when people are looking, and then either a) also eat next to nothing in private or else b) binge in secret, and feel terrible about yourself, neither of which are any good for you whatsoever.
Similarly, you can shame yourself out of bed, but you can’t shame yourself into the gym:
Let it go
There are some cases, especially those where shame has a large crossover with guilt, that it serves no purpose whatsoever, and is best processed and then put aside.
For example, if you did something that you are ashamed of many years ago, and/or feel guilty about something that you did many years ago, but this is not an ongoing thing for you (i.e., it was a one-off bad decision, or a bad habit that have now long since dropped), then feeling shame and/or guilt about that does not benefit you or anyone else.
As to how to process it and put it aside, if your thing harmed someone else, you could see if there’s a way to try to make amends (even if without confessing ill, such as by acting anonymously to benefit the person/group you harmed).
And then, forgive yourself. Regardless of whether you feel like you deserve it. Make the useful choice, that better benefits you, and by extension those around you.
If you are religious, you may find that of help here too. We’re a health science publication not a theological one, but for example: Buddhism preaches compassion including for oneself. Judaism preaches atonement. Christianity, absolution. For Islam, mercy is one of the holiest ideals of the religion, along with forgiveness. So while religion isn’t everyone’s thing, for those for whom it is, it can be an asset in this regard.
For a more worldly approach:

How To Escape From A Despairing Mood
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.
When we are in a despairing mood, that’s when it can feel hardest to actually implement anything we know about getting out of one. That’s why sometimes, the simplest solutions are the best:
Imagination Is Key
Despairing moods occur when it’s hard to envision a better life. Imagination is the power to envision alternatives, such as new jobs, relationships, or lifestyle, but sadness can cloud our ability to imagine solutions like changing careers, moving house, or starting fresh. With enough imagination, most problems can be worked around—and new opportunities can always be found.
Importantly: we are not bound by our past or present circumstances; we have the freedom and flexibility to choose new paths. That doesn’t mean it’ll always be a walk in the park, but “this too shall pass”.
You may be thinking: “sometimes the hardship does pass, but can last many years”, and that is true. All the more reason to check if there’s a freer lane you can slip into to speed ahead. Even if there isn’t, the mere act of imagining such lanes is already respite from the hardships—and having envisioned such will make it much easier for you to recognise when opportunities for change do come along.
To foster imagination, we are advised to expose ourselves to different narratives, preparing ourselves for alternative ways of living. Thus, we can reframe life’s challenges as intellectual puzzles, urging us to rebuild creatively and find new solutions!

How often should you wash your sheets and towels?
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.
Everyone seems to have a different opinion when it comes to how often towels and bed sheets should be washed. While many people might wonder whether days or weeks is best, in one survey from the United Kingdom, almost half of single men reported not washing their sheets for up to four months at a time.
It’s fairly clear that four months is too long to leave it, but what is the ideal frequency?
Bed linen and towels are quite different and so should be washed at different intervals. While every week or two will generally suffice for sheets, towels are best washed every few days.
Anyway, who doesn’t love the feeling of a fresh set of sheets or the smell of a newly laundered towel?
Why you should wash towels more often
When you dry yourself, you deposit thousands of skin cells and millions of microbes onto the towel. And because you use your towel to dry yourself after a shower or bath, your towel is regularly damp.
You also deposit a hefty amount of dead skin, microbes, sweat and oils onto your sheets every night. But unless you’re a prolific night sweater, your bedding doesn’t get wet after a night’s sleep.
Towels are also made of a thicker material than sheets and therefore tend to stay damp for longer.
So what is it about the dampness that causes a problem? Wet towels are a breeding ground for bacteria and moulds. Moulds especially love damp environments. Although mould won’t necessarily be visible (you would need significant growth to be able to see it) this can lead to an unpleasant smell.
As well as odours, exposure to these microbes in your towels and sheets can cause asthma, allergic skin irritations, or other skin infections.
People don’t always agree on how often to change the sheets.
http://rawpixel.com/ShutterstockSo what’s the ideal frequency?
For bedding, it really depends on factors such as whether you have a bath or shower just before going to bed, or if you fall into bed after a long, sweaty day and have your shower in the morning. You will need to wash your sheets more regularly in the latter case. As a rule of thumb, once a week or every two weeks should be fine.
Towels should ideally be washed more regularly – perhaps every few days – while your facecloth should be cleaned after every use. Because it gets completely wet, it will be wet for a longer time, and retain more skin cells and microbes.
Wash your towels at a high temperature (for example, 65°C) as that will kill many microbes. If you are conscious of saving energy, you can use a lower temperature and add a cup of vinegar to the wash. The vinegar will kill microbes and prevent bad smells from developing.
Clean your washing machine regularly and dry the fold in the rubber after every wash, as this is another place microbes like to grow.
Smelly towels
What if you regularly wash your towels, but they still smell bad? One of the reasons for this pong could be that you’ve left them in the washing machine too long after the wash. Especially if it was a warm wash cycle, the time they’re warm and damp will allow microbes to happily grow. Under lab conditions the number of these bacteria can double every 30 minutes.
It’s important to hang your towel out to dry after use and not to leave towels in the washing machine after the cycle has finished. If possible, hang your towels and bedding out in the sun. That will dry them quickly and thoroughly and will foster that lovely fresh, clean cotton smell. Using a dryer is a good alternative if the weather is bad, but outdoors in the sun is always better if possible.
Also, even if your towel is going to be washed, don’t throw a wet towel into the laundry basket, as the damp, dirty towel will be an ideal place for microbes to breed. By the time you get to doing your washing, the towel and the other laundry around it may have acquired a bad smell. And it can be difficult to get your towels smelling fresh again.
Towels should be washed more often than sheets.
New Africa/ShutterstockWhat about ‘self-cleaning’ sheets and towels?
Some companies sell “quick-dry” towels or “self-cleaning” towels and bedding. Quick-dry towels are made from synthetic materials that are weaved in a way to allow them to dry quickly. This would help prevent the growth of microbes and the bad smells that develop when towels are damp for long periods of time.
But the notion of self-cleaning products is more complicated. Most of these products contain nanosilver or copper, antibacterial metals that kill micro-organisms. The antibacterial compounds will stop the growth of bacteria and can be useful to limit smells and reduce the frequency with which you need to clean your sheets and towels.
However, they’re not going to remove dirt like oils, skin flakes and sweat. So as much as I would love the idea of sheets and towels that clean themselves, that’s not exactly what happens.
Also, excessive use of antimicrobials such as nanosilver can lead to microbes becoming resistant to them.

Nutrition To Combat Lymphedema & Lipedema
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. Kelly Sturm is a rehab specialist (Doctor of Physical Therapy), and also a certified lymphedema therapist. Here’s what helps her patients with lymphedema and lipedema:
Don’t fan the flames
Lymphedema and lipedema are inflammatory lymphatic diseases affecting mostly women. As such, an anti-inflammatory diet will be important, but there are other factors too:
- Anti-inflammatory diet: this is to reduce the chronic inflammation associated with lymphatic diseases. This means eating plenty of fruit and vegetables, especially berries and leafy greens, and avoiding things like sugar, alcohol, caffeine, and processed foods. And of course, don’t smoke.
- Intermittent fasting: this also helps by giving the body a chance to correct itself; when the body isn’t digesting food, it has a lot more resources to devote to its favorite activity: maintenance. This results in lower inflammation, and better fat redistribution.
- Weight loss: not a bandwagon we often get on at 10almonds as it’s rarely the most important thing, but in this case it is of high importance (second only to dealing with the inflammation), as excess weight around the lymph nodes and vessels can lead to dysfunction and swelling. Thus, reducing the weight can ease that and allow the body to heal.
