What’s Lurking In Your Household Air?

As individuals, we can’t do much about the outside air. We can try to spend more time in green spaces* and away from traffic, and we can wear face-masks—as was popular in Tokyo and other such large cities long before the pandemic struck.
*The well-known mental health benefits aside (and contrary to British politician Amber Rudd’s famous assertion in a televised political debate that “clean air doesn’t grow on trees”), clean air comes mostly from trees—their natural process of respiration scrubs not only carbon dioxide, but also pollutants, from the air before releasing oxygen without the pollutants. Neat!

We are fortunate to be living in a world where most of us in industrialized countries can exercise a great degree of control over our home’s climate. But, what to do with all that power?
Temperature
Let’s start with the basics. Outside temperature may vary, but you probably have heating and air conditioning. There’s a simple answer here; the optimal temperature for human comfort and wellbeing is 20℃ / 68℉:
Scientists Identify a Universal Optimal Temperature For Life on Earth
Note: this does not mean that that is the ideal global average temperature, because that would mean the polar caps are completely gone, the methane stored there released, many large cities underwater, currently hot places will be too hot for human life (e.g. outside temperatures above human body temperature), there will be mass extinctions of many kinds of animals and plants, including those we humans require for survival, and a great proliferation of many bugs that will kill us. Basically we need diversity for the planet to survive, arctic through to tropical and yes, even deserts (deserts are important carbon sinks!). The ideal global average temperature is about 14℃ (we currently have about 15℃ and rising).
But, for setting the thermostat in your home, 20℃ / 68℉ is perfect for most people, though down as far as 17℃ / 61℉ is fine too, provided other things such as humidity are in order. In fact, for sleeping, 18℃ / 62℉ is ideal. This is because the cooler temperature is one of the several things that tell our brain it is nighttime now, and thus trigger secretion of melatonin.
If you’re wondering about temperatures and respiratory viruses, by the way, check out:
The Cold Truth About Respiratory Infections: The Pathogens That Came In From The Cold
Humidity
Most people pay more attention to the temperature in their home than the humidity, and the latter is just as important:
❝Conditions that fall outside of the optimal range of 40–60% can have significant impacts on health, including facilitating infectious transmission and exacerbating respiratory diseases.
When humidity is too low, it can cause dryness and irritation of the respiratory tract and skin, making individuals more susceptible to infections.
When humidity is too high, it can create a damp environment that encourages the growth of harmful microorganisms like mould, bacteria, and viruses.❞
~ Dr. Gabriella Guarnieri et al.
So, if your average indoor humidity falls outside of that range, consider getting a humidifier or dehumidifier, to correct it. Example items on Amazon, for your convenience:

Now, one last component to deal with, for perfect indoor air:
Pollution
We tend to think of pollution as an outdoors thing, and indeed, the pollution in your home will (hopefully!) be lower than that of a busy traffic intersection. However…
- The air you have inside comes from outside, and that matters if you’re in an urban area
- Even in suburban and rural areas, general atmospheric pollutants will reach you, and if you’ve ever been subject to wildfire smoke, you’ll know that’s no fun either.
- Gas appliances in the home cause indoor pollution, even when carbon monoxide is within levels considered acceptable. This polluting effect is much stronger for open gas flames (such as on gas cookers/stoves, or gas fires), than for closed gas heating systems (such as a gas-powered boiler for central heating).
- Wood stoves/fireplaces are not an improvement, in fact they are worse, and don’t get us started on coal. You should not be breathing these things, and definitely should not be burning them in an enclosed space.
- That air conditioning, humidifier, dehumidifier? They may be great for temperature and humidity, but please clean/change the filter more often than you think is necessary, or things will grow there and then your device will be adding pathogens to the air as it goes.
- Plug-in air-freshening devices? They may smell clean, but they are effectively spraying cleaning fluids into your lungs. So please don’t.
So, what of air purifiers? They can definitely be of benefit. for example:
But watch out! Because if you don’t clean/change the filter regularly, guess what happens! That’s right, it’ll be colonized with bacteria/fungus and then be blowing those at you.
And no, not all of them will be visible to the naked eye:

The air is a very important factor for the health of your lungs (and thus, for the health of everything that’s fed oxygen by your lungs), but there are more things we can do as well:

How & Why Non-Sleep Deep Rest Works (And What Activities Trigger The Same State)
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.
Stress is a natural response that evolved over thousands of years to help humans meet challenges by priming the body and mind for action. However, chronic stress is harmful, as it diverts energy away from essential processes like cell maintenance and repair, leading to deterioration of health (physical and mental).
Counteracting this requires intentional periods of deep rest… But how?
Parasympathetic Response
Practices as diverse as mindfulness meditation, yoga, prayer, tai chi, qigong, knitting, painting, gardening, and sound baths can help induce states of deep rest—these days often called “Non-Sleep Deep Rest” (NSDR), to differentiate it from deep sleep.
How it works: these activities send signals to the brain that the body is safe, initiating biological changes that…
- protect chromosomes from DNA damage
- promote cellular repair, and
- enhance mitochondrial function.
If we then (reasonably!) conclude from this: “so, we must embrace moments of stillness and mindfulness, and allow ourselves to experience the ease and safety of the present”, that may sound a little wishy-washy, but the neurology of it is clear, the consequences of that neurological response on every living cell in the body are also clear, so by doing NSDR (whether by yoga nidra or knitting or something else) we can significantly improve our overall well-being.
Note: the list of activities above is far from exhaustive, but do be aware that this doesn‘t mean any activity you enjoy and do to unwind will trigger NSDR. On the contrary, many activities you enjoy and do to unwind may trigger the opposite, a sympathetic nervous system response—watching television is a common example of this “wrong choice for NSDR”. Sure, it can be absorbing and a distraction from your daily stressors, but it also can be exciting (both cognitively and neurologically and thus also physiologically), which is the opposite of what we want.

The Borderline Personality Disorder Workbook – by Dr. Daniel Fox
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.
Personality disorders in general get a bad rep. In part, because their names and descriptions often focus on how the disorders affect other people, rather than how they affect the actual sufferer:
- “This disorder gives you cripplingly low self-esteem; we call it Evil Not-Quite-Human Disorder”
- “This disorder makes you feel unloveable; we call it Abusive Bitch Disorder”
- …etc
Putting aside the labels and stigma, it turns out that humans sometimes benefit from help. In the case of BPD, characterized by such things as difficult moods and self-sabotage, the advice in this book can help anyone struggling with those (and related) issues.
The style of the book is both textbook, and course. It’s useful to proceed through it methodically, and doing the exercises is good too. We recommend getting the print edition, not the Kindle edition, so that you can check off boxes, write in it (pencil, if you like!), etc.
Bottom line: if you or a loved one suffers from BPD symptoms (whether or not you/they would meet criteria for diagnosis), this book can help a lot.

The Age-Proof Brain – by Dr. Marc Milstein

Biological aging is not truly just one thing, but rather the amalgam of many things intersecting—and most of them are modifiable. The cells of your body neither know nor care how many times you have flown around the sun; they just respond to the stimuli they’re given.
Which is what fuels this book. The idea is to have a brain that is less-assailed by the things that would make it age, and more rejuvenated by the things that can make it biologically younger.
Dr. Milstein doesn’t neglect the rest of the body, and indeed notes the brain’s connections with the immune system, the heart, the gut, and more. But everything in this book is done with the brain in mind and its good health as the top priority outcome of all the things he advises.
On which note, yes, there is plenty of practical, implementable advice here. For a book that is consistently full of study paper citations, he does take care to make everything useful to the reader, and makes everything as easy as possible for the layperson along the way.
Bottom line: if you would like your brain to age less, this is an excellent, very evidence-based, guidebook.

Self-Compassion In A Relationship (Positives & Pitfalls)
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.
Practise Self-Compassion In Your Relationship (But Watch Out!)
Let’s make clear up-front: this is not about “…but not too much”.
With that in mind…
Now let’s set the scene: you, a happily-partnered person, have inadvertently erred and upset your partner. They may or may not have already forgiven you, but you are still angry at yourself.
Likely next steps include all or any of:
- continuing to apologise and try to explain
- self-deprecatory diatribes
- self-flagellation, probably not literally but in the sense of “I don’t deserve…” and acting on that feeling
- self-removal, because you don’t want to further inflict your bad self on your partner
As you might guess, these are quite varied in their degree of healthiness:
- apologising is good, as even is explaining, but once it’s done, it’s done; let it go
- self-deprecation is pretty much never useful, let alone healthy
- self-flagellation likewise; it is not only inherently self-destructive, but will likely create an additional problem for your partner too
- self-removal can be good or bad depending on the manner of that removal: there’s a difference between just going cold and distant on your partner, and saying “I’m sorry; this is my fault not yours, I don’t want to take it out on you, so please give me half an hour by myself to regain my composure, and I will come back with love then if that’s ok with you”
About that last: mentioning the specific timeframe e.g. “half an hour” is critical, by the way—don’t leave your partner hanging! And then do also follow through on that; come back with love after the half-hour elapses. We suggest mindfulness meditation in the interim (here’s our guide to how), if you’re not sure what to do to get you there.
To Err Is Human; To Forgive, Healthy (Here’s How To Do It) ← this goes for when the forgiveness in question is for yourself, too—and we do write about that there (and how)!
This is important, by the way; not forgiving yourself can cause more serious issues down the line:
If, by the way, you’re hand-wringing over “but was my apology good enough really, or should I…” then here is how to do it. Basically, do this, and then draw a line under it and consider it done:
The Apology Checklist ← you’ll want to keep a copy of this, perhaps in the notes app on your phone, or a screenshot if you prefer
(the checklist is at the bottom of that page)
The catch
It’s you, you’re the catch 👈👈😎
Ok, that being said, there is actually a catch in the less cheery sense of the word, and it is:
“It is important to be compassionate about one’s occasional failings in a relationship” does not mean “It is healthy to be neglectful of one’s partner’s emotional needs; that’s self-care, looking after #1; let them take care of themself too”
…because that’s simply not being a couple at all.
Think about it this way: the famous airline advice,
“Put on your own oxygen mask before helping others with theirs”
…does not mean “Put on your own oxygen mask and then watch those kids suffocate; it’s everyone for themself”
So, the same goes in relationships too. And, as ever, we have science for this. There was a recent (2024) study, involving hundreds of heterosexual couples aged 18–73, which looked at two things, each measured with a scaled questionnaire:
- Subjective levels of self-compassion
- Subjective levels of relationship satisfaction
For example, questions included asking participants to rate, from 1–5 depending on how much they felt the statements described them, e.g:
In my relationship with my partner, I:
- treat myself kindly when I experience sorrow and suffering.
- accept my faults and weaknesses.
- try to see my mistakes as part of human nature.
- see difficulties as part of every relationship that everyone goes through once.
- try to get a balanced view of the situation when something unpleasant happens.
- try to keep my feelings in balance when something upsets me.
Note: that’s not multiple choice! It’s asking participants to rate each response as applicable or not to them, on a scale of 1–5.
And…
❝Women’s self-compassion was also positively linked with men’s total relationship satisfaction. Thus, men seem to experience overall satisfaction with the relationship when their female partner is self-kind and self-caring in difficult situations.
Unexpectedly, however, we found that men’s relationship-specific self-compassion was negatively associated with women’s fulfillment.
Baker and McNulty (2011) reported that, only for men, a Self-Compassion x Conscientiousness interaction explained whether the positive effects of self-compassion on the relationship emerged, but such an interaction was not found for women.
Highly self-compassionate men who were low in conscientiousness were less motivated than others to remedy interpersonal mistakes in their romantic relationships, and this tendency was in turn related to lower relationship satisfaction❞
~ Dr. Astrid Schütz et al. (2024)
And if you’d like to read the cited older paper from 2011, here it is:
Read in full: Self-compassion and relationship maintenance: the moderating roles of conscientiousness and gender
The take-away here is not: “men should not practice self-compassion”
(rather, they absolutely should)
The take-away is: we must each take responsibility for managing our own mood as best we are able; practice self-forgiveness where applicable and forgive our partner where applicable (and communicate that!)…. And then go consciously back to the mutual care on which the relationship is hopefully founded.
Which doesn’t just mean love-bombing, by the way, it also means listening:

To close… We say this often, but we mean it every time: take care!

“You Just Need to Lose Weight” And 19 Other Myths About Fat People – by Aubrey Gordon
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 previously reviewed another book by this author, “What We Don’t Talk About When We Talk About Fat”, and this time, she’s doing some important mythbusting.
The titular “you just need to lose weight” is a commonly-taken easy-out for many doctors, to avoid having to dispense actual treatment for an actual condition. Whether or not weight loss would help in a given situation is often immaterial; “kicking the can down the road” is the goal.
Most of the book is divided into 20 chapters, each of them devoted to debunking one myth. Think of it like 10almonds’ “Mythbusting Friday” edition (indeed, we did one about obesity), but with an entire book, and as much room as she needs to provide much more detail than we can ever get into in a single article.
And far from being a mere polemic, she does indeed provide that detail—this is clearly a very well-researched book, above and beyond the author’s own personal experience. Further, all the key points are illustrated and articulated clearly, making the book’s ideas very comprehensible.
The style is pop-science, but with frequent bibliographical references for relevant sources.
Bottom line: for some readers, this book will come as a great validation; for others, it may be eye-opening. Either way, it’s a very worthwhile read.

Widen the Window – by Dr. Elizabeth Stanley
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.
Firstly, about the title… That “window” that the author bids us “widen” is not a flowery metaphor, but rather, is referring to the window of exhibited resilience to stress/trauma; the “window” in question looks like an “inverted U” bell-curve on the graph.
In other words: Dr. Stanley’s main premise here is that we respond best to moderate stress (i.e: in that window, the area under the curve!), but if there is too little or too much, we don’t do so well. The key, she argues, is widening that middle part (expanding the area under the curve) in which we perform optimally. That way, we can still function in a motivated fashion without extrinsic threats, and we also don’t collapse under the weight of overwhelm, either.
The main strength of this book, however, lies in its practical exercises to accomplish that—and more.
“And more”, because the subtitle also promised recovery from trauma, and the author delivers in that regard too. In this case, it’s about widening that same window, but this time to allow one’s parasympathetic nervous system to recognize that the traumatic event is behind us, and no longer a threat; we are safe now.
Bottom line: if you would like to respond better to stress, and/or recover from trauma, this book is a very good tool.
