Are We Taking A Risk To Smell Fresh As A Daisy?
Yesterday, we asked you for your health-related view of underarm deodorants.
So, what does the science say?
They can cause (or increase risk of) cancer: True or False?
False, so far as we know. Obviously it’s very hard to prove a negative, but there is no credible evidence that deodorants cause cancer.
The belief that they do comes from old in vitro studies applying the deodorant directly to the cells in question, like this one with canine kidney tissues in petri dishes:
Antiperspirant Induced DNA Damage in Canine Cells by Comet Assay
Which means that if you’re not a dog and/or if you don’t spray it directly onto your internal organs, this study’s data doesn’t apply to you.
In contrast, more modern systematic safety reviews have found…
❝Neither is there clear evidence to show use of aluminum-containing underarm antiperspirants or cosmetics increases the risk of Alzheimer’s Disease or breast cancer.
Metallic aluminum, its oxides, and common aluminum salts have not been shown to be either genotoxic or carcinogenic.❞
(however, one safety risk it did find is that we should avoid eating it excessively while pregnant or breastfeeding)
Alternatives like deodorant rocks have fewer chemicals and thus are safer: True or False?
True and False, respectively. That is, they do have fewer chemicals, but cannot in scientific terms be qualifiably, let alone quantifiably, described as safer than a product that was already found to be safe.
Deodorant rocks are usually alum crystals, by the way; that is to say, aluminum salts of various kinds. So if it was aluminum you were hoping to avoid, it’s still there.
However, if you’re trying to cut down on extra chemicals, then yes, you will get very few in deodorant rocks, compared to the very many in spray-on or roll-on deodorants!
Soap and water is a safe, simple, and sufficient alternative: True or False?
True or False, depending on what you want as a result!
- If you care that your deodorant also functions as an antiperspirant, then no, soap and water will certainly not have an antiperspirant effect.
- If you care only about washing off bacteria and eliminating odor for the next little while, then yes, soap and water will work just fine.
Bonus myths:
There is no difference between men’s and women’s deodorants, apart from the marketing: True or False?
False! While to judge by the marketing, the only difference is that one smells of “evening lily” and the other smells of “chainsaw barbecue” or something, the real difference is…
- The “men’s” kind is designed to get past armpit hair and reach the skin without clogging the hair up.
- The “women’s” kind is designed to apply a light coating to the skin that helps avoid chafing and irritation.
In other words… If you are a woman with armpit hair or a man without, you might want to ignore the marketing and choose according to your grooming preferences.
Hopefully you can still find a fragrance that suits!
Shaving (or otherwise depilating) armpits is better for hygiene: True or False?
True or False, depending on what you consider “hygiene”.
Consistent with popular belief, shaving means there is less surface area for bacteria to live. And empirically speaking, that means a reduction in body odor:
However, shaving typically causes microabrasions, and while there’s no longer hair for the bacteria to enjoy, they now have access to the inside of your skin, something they didn’t have before. This can cause much more unpleasant problems in the long-run, for example:
❝Hidradenitis suppurativa is a chronic and debilitating skin disease, whose lesions can range from inflammatory nodules to abscesses and fistulas in the armpits, groin, perineum, inframammary region❞

And more: Hidradenitis suppurativa: Epidemiology, clinical presentation, and pathogenesis
If this seems a bit “damned if you do; damned if you don’t”, this writer’s preferred way of dodging both is to use electric clippers (the buzzy kind, as used for cutting short hair) to trim hers down low, and thus leave just a little soft fuzz.
What you do with yours is obviously up to you; our job here is just to give the information for everyone to make informed decisions whatever you choose 🙂
Take care!

The 5 Love Languages Gone Wrong
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.
Levelling up the 5 love languages
The saying “happy wife; happy life” certainly goes regardless of gender, and if we’re partnered, it’s difficult to thrive in our individual lives if we’re not thriving as a couple. So, with the usual note that mental health is also just health, let’s take a look at getting beyond the basics of a well-known, often clumsily-applied model:
The 5 love languages
You’re probably familiar with “the 5 love languages”, as developed by Dr. Gary Chapman. If not, they are:
- Acts of Service
- Gift-Giving
- Physical Touch
- Quality Time
- Words of Affirmation
The idea is that we each weight these differently, and problems can arise when a couple are “speaking a different language”.
So, is this a basic compatibility test?
It doesn’t have to be!
We can, if we’re aware of each other’s primary love languages, make an effort to do a thing we wouldn’t necessarily do automatically, to ensure they’re loved the way they need to be.
But…
What a lot of people overlook is that we can also have different primary love languages for giving and for receiving. And, missing that can mean that even taking each other’s primarily love languages into account, efforts to make a partner feel loved, or to feel loved oneself, can miss 50% of the time.
For example, I (your writer here today, hi) could be asked my primary love language and respond without hesitation “Acts of Service!” because that’s my go-to for expressing love.
I’m the person who’ll run around bringing drinks, do all the housework, and without being indelicate, will tend towards giving in the bedroom. But…
A partner trying to act on that information to make me feel loved by giving Acts of Service would be doomed to catastrophic failure, because my knee-jerk reaction would be “No, here, let me do that for you!”
So it’s important for partners to ask each other…
- Not: “what’s your primary love language?” ❌
- But: “what’s your primary way of expressing love?” ✅
- And: “which love language makes you feel most loved?” ✅
For what it’s worth, I thrive on Words of Affirmation, so thanks again to everyone who leaves kind feedback on our articles! It lets me know I provided a good Act of Service
So far, so simple, right? You and your partner (or: other person! Because as we’ve just seen, these go for all kinds of dynamics, not just romantic partnerships) need to be aware of each other’s preferred love languages for giving and receiving.
But…
There’s another pitfall that many fall into, and that’s assuming that the other person has the same idea about what a given love language means, when there’s more to clarify.
For example:
- Acts of Service: is it more important that the service be useful, or that it took effort?
- Gift-Giving: is it better that a gift be more expensive, or more thoughtful and personal?
- Physical Touch: what counts here? If we’re shoulder-to-shoulder on the couch, is that physical touch or is something more active needed?
- Quality Time: does it count if we’re both doing our own thing but together in the same room, comfortable in silence together? Or does it need to be a more active and involved activity together? And is it quality time if we’re at a social event together, or does it need to be just us?
- Words of Affirmation: what, exactly, do we need to hear? For romantic partners, “I love you” can often be important, but is there something else we need to hear? Perhaps a “because…”, or perhaps a “so much that…”, or perhaps something else entirely? Does it no longer count if we have to put the words in our partner’s mouth, or is that just good two-way communication?
Bottom line:
There’s a lot more to this than a “What’s your love language?” click-through quiz, but with a little application and good communication, this model can really resolve a lot of would-be problems that can grow from feeling unappreciated or such. And, the same principles go just the same for friends and others as they do for romantic partners.
In short, it’s one of the keys to good interpersonal relationships in general—something critical for our overall well-being!

Beating Toxic Positivity

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.

The Blue Zones, Second Edition – by Dan Buettner

Eat beans & greens, take walks, have a purpose; you can probably list off the top of your head some of the “advices from Blue Zones”, so what makes this book stand out?
This is perhaps one of the most thoughtful investigations; the author (a National Geographic researcher) toured and researched all the Blue Zones, took many many notes (we get details), and asked a lot of questions that others skipped.
For example, a lot of books about the Blue Zones mention the importance of community—but they don’t go into much detail of what that looks like… And they certainly don’t tend to explain what we should do about it.
And that’s because community is often viewed as environmental in a way that we can’t control. If we want to take supplements, eat a certain way, exercise, etc, we can do all those things alone if we want. But if we want community? We’re reliant on other people—and that’s a taboo in the US, and US-influenced places.
So, one way this book excels is in describing how exactly people foster community in the Blue Zones (hint: the big picture—the form of the community—is different in each place, but the individual actions taken are similar), with particular attention to the roles actively taken on by the community elders.
In a similar vein, “reduce stress” is good, but what mindsets and mechanisms do they use that are still reproducible if we are not, for example, Okinawan farmers? Again, Buettner delivers in spades.
Bottom line: this is the Blue Zones book that digs deeper than others, and makes the advices much more applicable no matter where we live.

Breathe; Don’t Vent (At Least In The Moment)

Zen And The Art Of Breaking Things
We’ve talked before about identifying emotions and the importance of being able to express them:
Answering The Most Difficult Question: How Are You?
However, there can be a difference between “expressing how we feel” and “being possessed by how we feel and bulldozing everything in our path”
…which is, of course, primarily a problem in the case of anger—and by extension, emotions that are often contemporaneous with anger, such as jealousy, shame, fear, etc.
How much feeling is too much?
While this is in large part a subjective matter, clinically speaking the key question is generally: is it adversely affecting daily life to the point of being a problem?
For example, if you have to spend half an hour every day actively managing a certain emotion, that’s probably indicative of something unusual, but “unusual” is not inherently bad. If you’re managing it safely and in a way that doesn’t negatively affect the rest of your life, then that is generally considered fine, unless you feel otherwise about it.
A good example of this is complicated grief and/or prolonged grief.
But what about when it comes to anger? How much is ok?
When it comes to those around you, any amount of anger can seem like too much. Anger often makes us short-tempered even with people who are not the object of our anger, and it rarely brings out the best in us.
We can express our feelings in non-aggressive ways, for example:
and
Seriously Useful Communication Skills!
Sometimes, there’s another way though…
Breathe; don’t vent
That’s a great headline, but we can’t take the credit for it, because it came from:
Breathe, don’t vent: turning down the heat is key to managing anger
…in which it was found that, by all available metrics, the popular wisdom of “getting it off your chest” doesn’t necessarily stand up to scrutiny, at least in the short term:
❝The work was inspired in part by the rising popularity of rage rooms that promote smashing things (such as glass, plates and electronics) to work through angry feelings.
I wanted to debunk the whole theory of expressing anger as a way of coping with it,” she said. “We wanted to show that reducing arousal, and actually the physiological aspect of it, is really important.❞
And indeed, he and his team did find that various arousal-increasing activities (such as hitting a punchbag, breaking things, doing vigorous exercise) did not help as much as arousal-decreasing activities, such as mindfulness-based relaxation techniques.
If you’d like to read the full paper, then so would we, but we couldn’t get full access to this one yet. However, the abstract includes representative statistics, so that’s worth a once-over:
Caveat!
Did you notice the small gap between their results and their conclusion?
In a lab or similar short-term observational setting, their recommendation is clearly correct.
However, if the source of your anger is something chronic and persistent, it could well be that calming down without addressing the actual cause is just “kicking the can down the road”, and will still have to actually be dealt with eventually.
So, while “here be science”, it’s not a mandate for necessarily suffering in silence. It’s more about being mindful about how we go about tackling our anger.

Wakefulness, Cognitive Enhancement, AND Improved 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.
Old Drug, New Tricks?
Modafinil (also known by brand names including Modalert and Provigil) is a dopamine uptake inhibitor.
What does that mean? It means it won’t put any extra dopamine in your brain, but it will slow down the rate at which your brain removes naturally-occuring dopamine.
The result is that your brain will get to make more use of the dopamine it does have.
(dopamine is a neutrotransmitter that allows you to feel wakeful and happy, and perform complex cognitive tasks)
Modafinil is prescribed for treatment of excessive daytime sleepiness. Often that’s caused by shift work sleep disorder, sleep apnea, restless leg syndrome, or narcolepsy.
Read: Overview of the Clinical Uses, Pharmacology, and Safety of Modafinil
Many studies done on humans (rather than rats) have been military experiments to reduce the effects of sleep deprivation:
Click Here To See A Military Study On Modafinil!
They’ve found modafinil to be helpful, and more effective and more long-lasting than caffeine, without the same “crash” later. This is for two reasons:
1) while caffeine works by blocking adenosine (so you don’t feel how tired you are) and by constricting blood vessels (so you feel more ready-for-action), modafinil works by allowing your brain to accumulate more dopamine (so you’re genuinely more wakeful, and you get to keep the dopamine)
2) the biological half-life of modafinil is 12–15 hours, as opposed to 4–8 hours* for caffeine.
*Note: a lot of sources quote 5–6 hours for caffeine, but this average is misleading. In reality, we are each genetically predetermined to be either a fast caffeine metabolizer (nearer 4 hours) or a slow caffeine metabolizer (nearer 8 hours).
What’s a biological half-life (also called: elimination half-life)?
A substance’s biological half-life is the time it takes for the amount in the body to be reduced by exactly half.
For example: Let’s say you’re a fast caffeine metabolizer and you have a double-espresso (containing 100mg caffeine) at 8am.
By midday, you’ll have 50mg of caffeine left in your body. So far, so simple.
By 4pm you might expect it to be gone, but instead you have 25mg remaining (because the amount halves every four hours).
By 8pm, you have 12.5mg remaining.
When midnight comes and you’re tucking yourself into bed, you still have 6.25mg of caffeine remaining from your morning coffee!
Use as a nootropic
Many healthy people who are not sleep-deprived use modafinil “off-label” as a nootropic (i.e., a cognitive enhancer).
Read: Modafinil for cognitive neuroenhancement in healthy non-sleep-deprived subjects: A systematic review
Important Note: modafinil is prescription-controlled, and only FDA-approved for sleep disorders.
To get around this, a lot of perfectly healthy biohackers describe the symptoms of sleep pattern disorder to their doctor, to get a prescription.
We do not recommend lying to your healthcare provider, and nor do we recommend turning to the online “grey market”.
Such websites often use anonymized private doctors to prescribe on an “informed consent” basis, rather than making a full examination. Those websites then dispense the prescribed medicines directly to the patient with no further questions asked (i.e. very questionable practices).
Caveat emptor!
A new mood-brightener?
Modafinil was recently tested head-to-head against Citalapram for the treatment of depression, and scored well:
See its head-to-head scores here!
How does it work? Modafinil does for dopamine what a lot of anti-depressants do for serotonin. Both dopamine and serotonin promote happiness and wakefulness.
This is very promising, especially as modafinil (in most people, at least) has fewer unwanted side-effects than a lot of common anti-depressant medications.

The Immunostimulant Superfood
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.
Eat These Greens!
Chlorella vulgaris, henceforth “chlorella”, is a simple green algae that has a lot of health benefits.
Note: most of the studies here are for Chlorella vulgaris specifically. However, some are for other species of the Chlorella genus, of which Chlorella vulgaris is by far the most common, hence the name (vulgaris = common). The relevant phytochemical properties appear to be the same regardless.
Superfood
While people generally take it as a supplement rather than a food item in any kind of bulk, it is more than 50% protein and contains all 9 essential amino acids.
As you might expect of a green superfood, it’s also full of many antioxidants, most of them carotenoids, and these pack a punch, for example against cancer:
It also has a lot of vitamins and minerals, and even omega-3.
Which latter also means it helps improve lipids and is thus particularly…
Heart healthy
❝Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol❞
Its heart-healthy benefits don’t stop at lipids though, and include blood pressure management, as in this study that found…
❝GABA-rich Chlorella significantly decreased high-normal blood pressure and borderline hypertension, and is a beneficial dietary supplement for prevention of the development of hypertension. ❞
About that GABA, if you’re curious about that, check out:
GABA Against Stress, Anxiety, & More
May remove heavy metals
We’re going with “may” for this one as we could only find animal studies so far (probably because most humans don’t have megadoses of heavy metals in them, which makes testing harder).
Here’s an example animal study, though:
Enhanced elimination of tissue methyl mercury in [Chlorella]-fed mice
Immunostimulant
This one’s clearer, for example in this 8-week study (with humans) that found…
❝Serum concentrations of interferon-γ (p<0.05) and interleukin-1β (p<0.001) significantly increased and that of interleukin-12 (p<0.1) tended to increase in the Chlorella group.
The increments of these cytokines after the intervention were significantly bigger in the Chlorella group than those in the placebo group. In addition, NK cell activities (%) were significantly increased in Chlorella group, but not in Placebo group.
The increments of NK cell activities (%) were also significantly bigger in the Chlorella group than the placebo group.
Additionally, changed levels of NK cell activity were positively correlated with those of serum interleukin-1β (r=0.280, p=0.047) and interferon-γ (r=0.271, p<0.005).❞
tl;dr = it boosts numerous different kinds of immune cells
PS, if you click though to the study, you may be momentarily alarmed by the first paragraph of the abstract that says “However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans“
this is from the “Background” section of the abstract, so what they are saying is “before we did this study, nobody had done this yet”.
So, be assured that the results are worthwhile and compelling.
Is it safe?
Based on the studies, it has a good safety profile. However, as it boosts the immune system, you may want to check with your doctor if you have an autoimmune disorder, and/or you are on immunosuppressants.
And in general, of course always check with your doctor/pharmacist if unsure about any potential drug interactions.
Want some?
We don’t sell it, but here for your convenience is an example product on Amazon
