War in Ukraine affected wellbeing worldwide, but people’s speed of recovery depended on their personality

The war in Ukraine has had impacts around the world. Supply chains have been disrupted, the cost of living has soared and we’ve seen the fastest-growing refugee crisis since World War II. All of these are in addition to the devastating humanitarian and economic impacts within Ukraine.

Our international team was conducting a global study on wellbeing in the lead up to and after the Russian invasion. This provided a unique opportunity to examine the psychological impact of the outbreak of war.

As we explain in a new study published in Nature Communications, we learned the toll on people’s wellbeing was evident across nations, not just in Ukraine. These effects appear to have been temporary – at least for the average person.

But people with certain psychological vulnerabilities struggled to recover from the shock of the war.

Tracking wellbeing during the outbreak of war

People who took part in our study completed a rigorous “experience-sampling” protocol. Specifically, we asked them to report their momentary wellbeing four times per day for a whole month.

Data collection began in October 2021 and continued throughout 2022. So we had been tracking wellbeing around the world during the weeks surrounding the outbreak of war in February 2022.

We also collected measures of personality, along with various sociodemographic variables (including age, gender, political views). This enabled us to assess whether different people responded differently to the crisis. We could also compare these effects across countries.

Our analyses focused primarily on 1,341 participants living in 17 European countries, excluding Ukraine itself (44,894 experience-sampling reports in total). We also expanded these analyses to capture the experiences of 1,735 people living in 43 countries around the world (54,851 experience-sampling reports) – including in Australia.

A global dip in wellbeing

On February 24 2022, the day Russia invaded Ukraine, there was a sharp decline in wellbeing around the world. There was no decline in the month leading up to the outbreak of war, suggesting the change in wellbeing was not already occurring for some other reason.

However, there was a gradual increase in wellbeing during the month after the Russian invasion, suggestive of a “return to baseline” effect. Such effects are commonly reported in psychological research: situations and events that impact our wellbeing often (though not always) do so temporarily.

Unsurprisingly, people in Europe experienced a sharper dip in wellbeing compared to people living elsewhere around the world. Presumably the war was much more salient for those closest to the conflict, compared to those living on an entirely different continent.

Interestingly, day-to-day fluctuations in wellbeing mirrored the salience of the war on social media as events unfolded. Specifically, wellbeing was lower on days when there were more tweets mentioning Ukraine on Twitter/X.

Our results indicate that, on average, it took around two months for people to return to their baseline levels of wellbeing after the invasion.

Different people, different recoveries

There are strong links between our wellbeing and our individual personalities.

However, the dip in wellbeing following the Russian invasion was fairly uniform across individuals. None of the individual factors assessed in our study, including personality and sociodemographic factors, predicted people’s response to the outbreak of war.

On the other hand, personality did play a role in how quickly people recovered. Individual differences in people’s recovery were linked to a personality trait called “stability”. Stability is a broad dimension of personality that combines low neuroticism with high agreeableness and conscientiousness (three traits from the Big Five personality framework).

Stability is so named because it reflects the stability of one’s overall psychological functioning. This can be illustrated by breaking stability down into its three components:

  1. low neuroticism describes emotional stability. People low in this trait experience less intense negative emotions such as anxiety, fear or anger, in response to negative events
  2. high agreeableness describes social stability. People high in this trait are generally more cooperative, kind, and motivated to maintain social harmony
  3. high conscientiousness describes motivational stability. People high in this trait show more effective patterns of goal-directed self-regulation.

So, our data show that people with less stable personalities fared worse in terms of recovering from the impact the war in Ukraine had on wellbeing.

In a supplementary analysis, we found the effect of stability was driven specifically by neuroticism and agreeableness. The fact that people higher in neuroticism recovered more slowly accords with a wealth of research linking this trait with coping difficulties and poor mental health.

These effects of personality on recovery were stronger than those of sociodemographic factors, such as age, gender or political views, which were not statistically significant.

Overall, our findings suggest that people with certain psychological vulnerabilities will often struggle to recover from the shock of global events such as the outbreak of war in Ukraine.The Conversation

  • Macadamia Nuts vs Brazil Nuts – 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 macadamia nuts to Brazil nuts, we picked the Brazil nuts.

    Why?

    They’re a lot more nutrient dense! But watch out…

    First, to do due diligence in terms of macros: Brazil nuts have twice as much protein and less fat, as well as being a little higher in fiber and slightly lower in carbs.

    In terms of vitamins, Brazil nuts are about 10x higher in vitamin E, while macadamias are somewhat higher in several B-vitamins.

    The category of minerals is where it gets interesting. Macadamia nuts are a little higher in iron and considerably higher in Manganese. But… Brazil nuts are a lot higher in calcium, copper, magnesium, phosphorus, potassium, selenium, and zinc.

    About that selenium… Specifically, it’s more than 5,000x higher, and a cup of Brazil nuts would give nearly 10,000x the recommended daily amount of selenium. Now, selenium is an essential mineral (needed for thyroid hormone production, for example), and at the RDA it’s good for good health. Your hair will be luscious and shiny. However, go much above that, and selenium toxicity becomes a thing, you may get sick, and it can cause your (luscious and shiny) hair to fall out. For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.

    In short… Brazil nuts are much more nutrient dense in general, and thus come out on top here. But, they’re so nutrient dense in the case of selenium, that careful moderation is advised.

  • Prolonged Grief: A New Mental Disorder?

    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 issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.

    The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) features a new diagnosis: prolonged grief disorder—used for those who, a year after a loss, still remain incapacitated by it. This addition follows more than a decade of debate. Supporters argued that the addition enables clinicians to provide much-needed help to those afflicted by what one might simply consider a too much of grief, whereas opponents insisted that one mustn’t unduly pathologize grief and reject an increasingly medicalized approach to a condition that they considered part of a normal process of dealing with loss—a process which in some simply takes longer than in others.    

    By including a condition in a professional classification system, we collectively recognize it as real. Recognizing hitherto unnamed conditions can help remove certain kinds of disadvantages. Miranda Fricker emphasizes this in her discussion of what she dubs hermeneutic injustice: a specific sort of epistemic injustice that affects persons in their capacity as knowers1. Creating terms like ‘post-natal depression’ and ‘sexual harassment’, Fricker argues, filled lacunae in the collectively available hermeneutic resources that existed where names for distinctive kinds of social experience should have been. The absence of such resources, Fricker holds, put those who suffered from such experiences at an epistemic disadvantage: they lacked the words to talk about them, understand them, and articulate how they were wronged. Simultaneously, such absences prevented wrong-doers from properly understanding and facing the harm they were inflicting—e.g. those who would ridicule or scold mothers of newborns for not being happier or those who would either actively engage in sexual harassment or (knowingly or not) support the societal structures that helped make it seem as if it was something women just had to put up with. 

    For Fricker, the hermeneutical disadvantage faced by those who suffer from an as-of-yet ill-understood and largely undiagnosed medical condition is not an epistemic injustice. Those so disadvantaged are not excluded from full participation in hermeneutic practices, or at least not through mechanisms of social coercion that arise due to some structural identity prejudice. They are not, in other words, hermeneutically marginalized, which for Fricker, is an essential characteristic of epistemic injustice. Instead, their situation is simply one of “circumstantial epistemic bad luck”2. Still, Fricker, too, can agree that providing labels for ill-understood conditions is valuable. Naming a condition helps raise awareness of it, makes it discursively available and, thus, a possible object of knowledge and understanding. This, in turn, can enable those afflicted by it to understand their experience and give those who care about them another way of nudging them into seeking help. 

    Surely, if adding prolonged grief disorder to the DSM-5 were merely a matter of recognizing the condition and of facilitating assistance, nobody should have any qualms with it. However, the addition also turns intense grief into a mental disorder—something for whose treatment insurance companies can be billed. With this, significant forces of interest enter the scene. The DSM-5, recall, is mainly consulted by psychiatrists. In contrast to talk-therapists like psychotherapists or psychoanalysts, psychiatrists constitute a highly medicalized profession, in which symptoms—clustered together as syndromes or disorders—are frequently taken to require drugs to treat them. Adding prolonged grief disorder thus heralds the advent of research into various drug-based grief therapies. Ellen Barry of the New York Times confirms this: “naltrexone, a drug used to help treat addiction,” she reports, “is currently in clinical trials as a form of grief therapy”, and we are likely to see a “competition for approval of medicines by the Food and Drug Administration.”3

    Adding diagnoses to the DSM-5 creates financial incentives for players in the pharmaceutical industry to develop drugs advertised as providing relief to those so diagnosed. Surely, for various conditions, providing drug-induced relief from severe symptoms is useful, even necessary to enable patients to return to normal levels of functioning. But while drugs may help suppress feelings associated with intense grief, they cannot remove the grief. If all mental illnesses were brain diseases, they might be removed by adhering to some drug regimen or other. Note, however, that ‘mental illness’ is a metaphor that carries the implicit suggestion that just like physical illnesses, mental afflictions, too, are curable by providing the right kind of physical treatment. Unsurprisingly, this metaphor is embraced by those who stand to massively benefit from what profits they may reap from selling a plethora of drugs to those diagnosed with any of what seems like an ever-increasing number of mental disorders. But metaphors have limits. Lou Marinoff, a proponent of philosophical counselling, puts the point aptly:

    Those who are dysfunctional by reason of physical illness entirely beyond their control—such as manic-depressives—are helped by medication. For handling that kind of problem, make your first stop a psychiatrist’s office. But if your problem is about identity or values or ethics, your worst bet is to let someone reify a mental illness and write a prescription. There is no pill that will make you find yourself, achieve your goals, or do the right thing.

    Much more could be said about the differences between psychotherapy, psychiatry, and the newcomer in the field: philosophical counselling. Interested readers may benefit from consulting Marinoff’s work. Written in a provocative, sometimes alarmist style, it is both entertaining and—if taken with a substantial grain of salt—frequently insightful. My own view is this: from Fricker’s work, we can extract reasons to side with the proponents of adding prolonged grief disorder to the DSM-5. Creating hermeneutic resources that allow us to help raise awareness, promote understanding, and facilitate assistance is commendable. If the addition achieves that, we should welcome it. And yet, one may indeed worry that practitioners are too eager to move from the recognition of a mental condition to the implementation of therapeutic interventions that are based on the assumption that such afflictions must be understood on the model of physical disease. The issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.

    No doubt, grief manifests physically. It is, however, not primarily a physical condition—let alone a brain disease. Grief is a distinctive mental condition. Apart from bouts of sadness, its symptoms typically include the loss of orientation or a sense of meaning. To overcome grief, we must come to terms with who we are or can be without the loved one’s physical presence in our life. We may need to reinvent ourselves, figure out how to be better again and whence to derive a new purpose. What is at stake is our sense of identity, our self-worth, and, ultimately, our happiness. Thinking that such issues are best addressed by popping pills puts us on a dangerous path, leading perhaps towards the kind of dystopian society Aldous Huxley imagined in his 1932 novel Brave New World. It does little to help us understand, let alone address, the moral and broader philosophical issues that trouble the bereaved and that lie at the root not just of prolonged grief but, arguably, of many so-called mental illnesses.

    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

    ❝Hi! I’ve been reading about LifeWave patches, would you recommend them?❞

    For reference first, this is talking about these: LifeWave.com

    Short answer: no

    Longer answer: their main premise seems to be that the patches (subscription prices seem to start from about $100–$300 per month) reflect infrared energy back into your body, making you more energized and healthy.

    Fun fact: aluminum foil reflects infrared energy (which we feel as heat), by the way, and that is why space blankets (of the kind used in emergencies and by some athletes) are made shiny like that, often with aluminized mylar.

    We cannot comment too closely on the rest of the presented science of their products, as it seems quite unlike anything we’re accustomed to reading, and we were not able to make a lot of sense of it.

    They do cite research papers to back their claims, including research conducted by the company’s founder and published via an open journal.

    Many others are independent studies conducted by often the same researchers as each other, mostly experts in acupuncture and acupressure.

    For the papers we looked at, the sample sizes were very small, but the conclusions were very positive.

    They were published in a variety of journals, of which we cannot claim any prior knowledge (i.e:, they were not the peer-reviewed journals from which we cite most of our sources).

    Also, none were registered with ClinicalTrials.gov.

    To be on the safe side, their disclaimer does advise:

    ❝LifeWave products are only intended to maintain or encourage a general state of health or healthy activity and are not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition of the body❞

    They do have a Frequently Asked Questions page, which tells about ancient Egyptian use of colored glass, as well as more modern considerations including joining, ordering, their commissions system, binary commissions and matching bonuses, and “how to rank up in LifeWave” as well as a lot of information about subscribing as a preferred customer or a brand partner, opting in to their multi-level marketing opportunities.

    Here’s what “Honest Brand Reviews” had to say:

    Our position:

    We cannot honestly claim to understand their science, and thus naturally won’t actively recommend what we can’t speak for.

    An expert’s position:

  • Beating Toxic Positivity

    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.

    How To Get Your Brain On A More Positive Track (Without Toxic Positivity)

    There have been many studies done regards optimism and health, and they generally come to the same conclusion: optimism is simply good for the health.

    Here’s an example we’ve mentioned before, but it’s a good introduction to today’s main feature. It’s a longitudinal study, and it followed 121,700 women (what a sample size!) for eight years. It controlled for all kinds of other lifestyle factors (especially smoking, drinking, diet, and exercise habits, as well as pre-existing medical conditions), so this wasn’t a case of “people who are healthy are more optimistic as results. And, in the researchers’ own words…

    ❝We found strong and statistically significant associations of increasing levels of optimism with decreasing risks of mortality, including mortality due each major cause of death, such as cancer, heart disease, stroke, respiratory disease, and infection. Importantly, findings were maintained after close control for potential confounding factors, including sociodemographic characteristics and depression❞

    Read: Optimism and Cause-Specific Mortality: A Prospective Cohort Study

    And yet, toxic positivity can cause as many problems as it tries to fix.

    What is toxic positivity?

    • Toxic positivity is the well-meaning friend who says “I’m sure it’ll be ok” when you know full well it definitely will not.
    • Toxic positivity is the allegorical frog-in-a-pan saying that the temperature rises due to climate change are gradual, so they’re nothing to worry about
    • Toxic positivity is thinking that “good vibes” will outperform chemotherapy

    Sometimes, a dose of realism is needed. So, can we do that and maintain a positive attitude?

    The answer is: somewhat, yes! But first, a quick check-in:

    ❝I’m not a pessimist; I’m a realist!❞

    ~ every pessimist ever

    To believe self-reports, the world is divided between optimists and realists. But how does your outlook measure up, really?

    While like most free online tests, this is offered “as-is” with the usual caveats about not being a clinical diagnostic tool, this one actually has a fair amount of scientific weight behind it:

    ❝Empirical testing has indicated the validity of the Optimism Pessimism Instrument as published in the scientific journal Current Psychology: Research and Reviews.

    The IDRlabs Optimism/Pessimism Test (IDR-OPT) was developed by IDRlabs. The IDR-OPT is based on the Optimism/Pessimism Instrument (OPI) developed by Dr. William Dember, Dr. Stephanie Martin, Dr. Mary Hummer, Dr. Steven Howe, and Dr. Richard Melton, at the University of Cincinnati.❞

    Take This Short (1–2 mins) Test

    How did you score? And what could you do to improve on that score?

    First, it’s said that with a big enough “why”, one can overcome any “how”. So…

    An attitude of gratitude

    We know, we know, it’s very Oprah Winfrey. But also, it works. Take the time, ideally daily, to quickly list 3–5 things for which you feel grateful. Great or small, it can be anything from your spouse to your cup of coffee, provided you feel fortunate to have it.

    How this works: our brains easily get stuck in loops, so it can help to nudge them into a more positive loop.

    What about when we are treated unfairly? Are we supposed to be grateful?

    Sometimes, our less positive emotions are necessary, to protect us and/or those around us, and to provide a motivational force. We can still maintain a positive attitude by noting the bad thing and some good, but watch out! Notice the difference:

    • “How dare they take our healthcare away, but at least I’m not sick right now” (lasting impression: no action required)
    • “At least I’m not sick right now, but how dare they take our healthcare away!” (lasting impression: action required)

    It’s a well-known idea in neurolinguistic programming, that “but” negates whatever goes before it (think of “I’m sorry but”, or “I’m not racist but”, etc), so use it consciously and wisely, or else simply use “and” instead.

    Cognitive reframing: problem, or opportunity?

    Most problems can be opportunities, even if the problems themselves genuinely suck and are not intrinsically positive. A way of leveraging this can be replacing “I have to…” with “I get to…”.

    This not only can reframe problems as opportunities, but also calls back to the gratitude idea.

    • Instead of “I have to get my mammogram / prostate exam” (not generally considered fun activities), “I get to have the peace of mind of being free from cancer / I get to have the forewarning that will keep me safe”.
    • Instead of “I have to go to work”, “I get to go to work” (many wish they were in your shoes!)
    • Instead of “I have to rest”, “I get to rest”

    When things are truly not great

    Whether due to internal or external factors, whether you can control something or not, sometimes things are truly not great. The trick here is that in most contexts, one can replace negative talk, with verbally positive talk, no matter how dripping with scathing irony. You’ll still get to express the idea you wanted, but your brain will feel more positive and you’ll be in a positive loop rather than a negative one.

    This, by the way, is the inverse of talking to a dog with a tone of voice that is completely the opposite of the meaning of the words. Whereas the dog will interpret the tone only, your brain will interpret the words only.

    • You just spilled your drink over yourself at a social function? “Aren’t I the very model of grace and charm?”
    • You made a costly mistake in your business dealings? “I am such a genius”
    • You just got a diagnosis of a terrible disease? “Well, this is fabulous”

    None of these things involve burying your head in the sand, in the manner of toxic positivity. You’ll still learn from your business mistake and correct it as best you can, or take appropriate action regards the disease, for example.

    You’ll just feel better while you do it, and not get caught into a negative spiral that ruins your day, or even your next few months.

    Sympathetic/Somatic Therapy:

    Lastly, an easy one, leveraging the body’s tendency to get in sync with things around us:

    For when you do just need a mood change, have an uplifting playlist available at the touch of a button. It’s hard to be consumed with counterproductive feelings to the tune of “Walking on Sunshine”!

    Bonus tip: consider having the playlist start with something that is lyrically negative while musically upbeat. That way, your brain won’t resist it as antithetical to your mood, and by the second track, you’ll already be on your way to a better mood.

  • Are Fruit & Vegetable Extract Supplements Worth 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.

    At 10almonds we are always extolling the virtues of fruits and vegetables, but how much do those benefits still exist when we’re looking at a fruit and vegetable extract supplement?

    We examined one aspect of this previously, here;

    Mediterranean Diet… In A Pill?

    This looked at getting the anti-inflammatory benefits of the Mediterranean diet, in supplement form, by providing extracts of 16 key plant extracts—which also provides an excellent shopping list, by the way, if you just want to skip the supplements and buy those plants; if nine top scientists (anti-aging specialists, neurobiologists, pharmacologists, and at least one professor of applied statistics) came to the conclusion that to get the absolute most bang-for-buck possible, those are the plants to get the phytochemicals from, then we’re not going to ignore that!

    And yes, the short answer was “it does very significantly improve anti-inflammatory markers”, by the way.

    But when it comes to benefits from polyphenols, anti-inflammatory powers are very much “low-hanging fruit”, so to speak. It’s the “fork found in kitchen” level of shocking revelation. It’s what polyphenols are best at (tied with antioxidant powers, which directly mediate their anti-inflammatory powers).

    So, what about something more challenging, like brain benefits?

    Underrated Brain Boosters

    A European research team (Dr. Begoña Cerdá et al.) looked at the effects of polyphenol-rich nutraceuticals (plant extracts) on cognitive function and neuroprotection biomarkers.

    It was a randomized, crossover, double-blind, sex-stratified, placebo-controlled clinical trial that had people take the supplement or a placebo for 16 weeks, have a 4-week washout phase (to minimize leftover effects contaminating the data) and then switching groups (still blinded to the placebo control) for 16 weeks.

    They tested cognitive function and neuroprotection biomarkers in various ways before and after each of the testing phases (so, four testing sessions in total per person: before and after the supplement + before and after the placebo).

    The results:

    ❝The results suggested that participants who consumed the polyphenol-rich nutraceutical demonstrated significant improvements in cognitive performance compared to the placebo group.

    The Stroop Test scores indicated enhanced attention and inhibitory control, while RIST results suggested improvements in logical reasoning and memory. The Trail Making Test also revealed increased cognitive flexibility, highlighting the supplement’s potential to boost overall mental agility.

    Furthermore, the ELISA results showed a notable increase in BDNF and CREB levels among participants who took the active supplement. BDNF is a protein that is essential for neuronal growth and survival, and its levels were significantly elevated, reinforcing its role in synaptic plasticity and long-term memory formation.

    Additionally, CREB, a transcription factor involved in learning processes, also showed increased levels, supporting its function in cognitive enhancement.

    Importantly, the correlation between improved test scores and higher biomarker levels suggested that polyphenols may directly influence brain function rather than merely offering general health benefits.

    While the study focused on healthy adults, the findings also raised questions about whether similar interventions could benefit populations at risk for cognitive decline, including older adults and individuals with neurodegenerative conditions.❞

    For those who do want to dive into the actual data and a lot more detail about the study methodology (which is well worth reading if you have the time, as it’s very good), here is the actual study:

    Impact of Polyphenol-Rich Nutraceuticals on Cognitive Function and Neuroprotective Biomarkers: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

    If nothing else, be aware that the usual benchmark for statistical significance is p < 0.05, whereas the results in this study ranged from p < 0.01 to p < 0.001, in other words, ranging from 5x more significant than is required to be called “significant”, to 50x more significant than is required to be called “significant”.

    In fewer words: impressively significant

    In lay terms: the scientists are about as sure as scientists ever get about anything, that this supplement produces significant results

    What was the supplement they tested?

    Good news! It was…

    1. a commercially available supplement (JuicePlus), which is convenient, because it means we (and you, dear reader) can get it if we so choose
    2. not paid for by JuicePlus or anyone associated with them (indeed, the funding declaration on the study is “This research received no external funding”), so not subject to any conflict of interest that might introduce bias into the study

    As for why they chose that one:

    ❝A unique aspect of the polyphenol-rich nutraceutical evaluated in this study lies in its composition, which integrates a blend of fruit, vegetable, and berry juice powders.

    This product, Juice Plus+ Premium®, contains over 119 distinct polyphenolic compounds, including flavanols, anthocyanins, and flavones, as demonstrated in prior compositional analyses.

    Compared to other polyphenol-based interventions, this nutraceutical stands out due to its comprehensive formulation, combining a wide range of bioactive compounds with complementary antioxidant and neuroprotective effects.

    These characteristics ensure a more diverse interaction with neurobiological pathways, including those related to oxidative stress mitigation, synaptic plasticity, and cognitive function❞
