That’s not a typo! The name “glymphatic system” was coined by the Danish neuroscientist Dr. Maiken Nedergaard, and is a nod to its use of glial cells to do a similar job to that of the peripheral lymphatic system—but this time, in the CNS. Today, we have Dr. Jin Sung to tell us more:
Brainwashing (but not like that)
The glymphatic system may sound like a boring job, but so does “sanitation worker” in a city—yet the city would grind to a messy halt very very quickly without them. Same goes for your brain.
Diseases that are prevalent when this doesn’t happen the way it should include Alzheimer’s (beta-amyloid clearance) and Parkinson’s (alpha-synuclein clearance) amongst others.
Things Dr. Sung recommends for optimal glymphatic function include: sleep (7–9 hours), exercise (30–45 minutes daily), hydration (half your bodyweight in pounds, in ounces, so if your body weighs 150 lbs, that means 75 oz of water), good posture (including the use of good ergonomics, e.g. computer monitor at right height, car seat correct, etc), stress reduction (reduces inflammatory cytokines), getting enough omega-3 (the brain needs certain fats to work properly, and this is the one most likely to see a deficit), vagal stimulation (methods include humming, gargling, and gagging—please note we said vagal stimulation; easy to misread at a glance!), LED light therapy, and fasting (intermittent or prolonged).

❝Interesting about DVT after surgery. A friend recently got diagnosed with foot drop. Could you explain that? Thank you.❞
First, for reference, the article about DVT after surgery was:
DVT Risk Management Beyond The Socks
As for foot drop…
Foot drop is descriptive of the main symptom: the inability to raise the front part of the foot due to localized weakness/paralysis. Hence, if a person with foot drop dangles their feet over the edge of the bed, for example, the affected foot will simply flop down, while the other (if unaffected) can remain in place under its own power. The condition is usually neurological in origin, though there are various more specific causes:
When walking unassisted, this will typically result in a distinctive “steppage gait”, as it’s necessary to lift the foot higher to compensate, or else the toes will scuff along the ground.
There are mobility aids that can return one’s walking to more or less normal, like this example product on Amazon.
Incidentally, the above product will slightly shorten the lifespan of shoes, as it will necessarily pull a little at the front.
There are alternatives that won’t like this example product on Amazon, but this comes with the different problem that it limits the user to stepping flat-footedly, which is not only also not an ideal gait, but also, will serve to allow any muscles down there that were still (partially or fully) functional to atrophy. For this reason, we’d recommend the first product we mentioned over the second one, unless your personal physiotherapist or similar advises otherwise (because they know your situation and we don’t).
Both have their merits, though:

Stop Tinnitus, & Improve Your Hearing By 130%
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.
Caveat: this will depend on the cause of your tinnitus, but there’s a quick diagnostic test first, and it’s for the most common kind 🙂
Step by step
To address noise in the ears (tinnitus) and improve hearing, start by identifying whether the issue is treatable. The diagnostic tests are:
- First, turn your head to the side, tilt it forward and backward, and observe changes in the noise. If the intensity changes, then the noise can be managed.
- Additionally, open and close your mouth, clenching and unclenching your teeth, and note any variations; this is about muscular tension affecting hearing.
- Finally, tilt your head downward—if the noise increases, it may mean it is a venous outflow disorder—there’s a fix for this, too.
Effective exercises focus on releasing tension and improving blood flow:
- Begin with the neck’s scalene muscles, located behind the sternocleidomastoid muscle.
- Massage these areas by moving your hands up and down and varying head positions slightly forward and backward.
- Repeat on both sides to enhance blood circulation and reduce auditory interference. Next, target the chewing muscles.
- Massage painful areas of the jaw and temporalis muscle in circular motions, working along and across the muscle fibers.
- Divide the temporalis muscle into sections and address each thoroughly to relieve tension and improve hearing.
- Mobilize the outer auditory passage by gently pulling the ear in all directions—starting with the earlobe, middle part, and upper ear.
- Focus on the cartilage above the lobe, moving it up and down to restore mobility and improve blood flow.
These exercises should fix the most common kind of tinnitus, and improve hearing—you’ll know quickly whether it works for you or not. Regular practice is required for sustained results, though.
For more on all this, plus visual demonstrations (e.g. how to find that temporalis muscle, etc), enjoy:

Dealing With Back Acne

It’s Q&A Day at 10almonds!

❝Lately I’ve increasingly been getting zits on my back, I don’t think my shower habits have changed at all, is this just an age thing or is there something I can do about it?❞
Well, we cannot diagnose from afar, so definitely consider seeing a dermatologist if it persists and/or it’s more than a small nuisance to you, but…
Yes and no, with regard to age.
Rather, it’s not really about age, but (in most cases, anyway) hormonal fluctuations. That’s why teenagers often get it; it’s also why acne breakouts can occur during pregnancy, and it can happen again in perimenopause, menopause, or in the postmenopause climb-down, due to imbalanced hormones during the change, and while it’s less likely for men undergoing the andropause (the noticeable drop of testosterone levels after a certain age), it can absolutely occur if taking certain androgenic supplements, including simply taking testosterone (or conversely, if taking something to dial down antagonistic hormones). It can also happen if you’re taking something that throws out your free testosterone to DHT ratio.
As for what to do in this case? The usual process is: just wait it out. At some point your hormones will become stable again (nature loves equilibrium, and the body is mostly a self-righting system if given what it needs to do that), and your skin will return to normal. To be clear: the acne occurs because of the change, not necessarily the end place. So whatever hormone levels you have, be they medicated or otherwise, you just need to keep them stable now (assuming the levels are fine; if not, get them fine, and then keep them stable—speak to an endocrinologist for that) in order to come out the other side acne-free.
However, that’s “the usual process”, and obviously we cannot guarantee it’s not something else. It can also be caused by stress:
The Impact of Pyschological Stress on Acne ← teehee, a typo made it into the publication title
…in which case, of course, simply manage your stress (we know, often easier said than done, but the point is, that’s the remedy in this case).
See also: How To Reduce Chronic Stress
Diet is not the cause (or cure), but enjoying an anti-inflammatory diet will be beneficial, and consuming inflammatory things, exacerbatory:
Effects of Diet on Acne and Its Response to Treatment
Hygiene is also rarely to blame, but it can make a difference, so: do wash gently, wear clean clothes, and wash your bedsheets more often than you think necessary. And about that showering:

16 Overlooked Autistic Traits In Women
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 hear a lot about “autism moms”, but Taylor Heaton is an autistic mom, diagnosed as an adult, and she has insights to share about overlooked autistic traits in women.
The Traits
- Difficulty navigating romantic relationships: often due to misreading signs
- Difficulty understanding things: including the above, but mostly: difficulty understanding subtext, when people leave things as “surely obvious”. Autistic women are likely to be aware of the possible meanings, but unsure which it might be, and may well guess wrongly.
- Masking: one of the reasons for the gender disparity in diagnosis is that autistic women are often better at “masking”, that is to say, making a conscious effort to blend in to allistic society—often as a result of being more societally pressured to do so.
- Honesty: often to a fault
- Copy and paste: related to masking, this is about consciously mirroring others in an effort to put them at ease and be accepted
- Being labelled sensitive and/or gifted: usually this comes at a young age, but the resultant different treatment can have a lifetime effect
- Secret stims: again related to masking, and again for the same reasons that displaying autistic symptoms is often treated worse in women, autistic women’s stims tend to be more subtle.
- Written communication: autistic women are often more comfortable with the written word than the spoken
- Leadership: autistic women will often gravitate to leadership roles, partly as a survival mechanism
- Gaslighting: oneself, e.g. “If this person did this without that, then I can to” (without taking into account that maybe the circumstances are different, or maybe they actually did lean on crutches that you didn’t know were there, etc).
- Inner dialogue: rich inner dialogue, but unable to express it outwardly—often because of the sheer volume of thoughts per second.
- Fewer female friends: often few friends overall, for that matter, but there’s often a gender imbalance towards male friends, or where there isn’t, towards more masculine friends at least.
- Feeling different: often a matter of feeling one does not meet standard expectations in some fashion
- School: autistic women are often academically successful
- Special interests: often more “socially accepted” interests than autistic men’s.
- Flirting: autistic women are often unsure how to flirt or what to do about it, which can result in simple directness instead

How gender-affirming care improves trans mental health
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.
In recent years, a growing number of states have passed laws restricting or banning gender-affirming care for transgender people, particularly minors. As conversations about gender-affirming care increase, so do false narratives about it, with some opponents falsely suggesting that it’s harmful to mental health.
Despite widespread attacks against gender-affirming care, research clearly shows that it improves mental health outcomes for transgender people.
Read on to learn more about what gender-affirming care is, how it benefits mental well-being, and how you can access it.
What is gender-affirming care?
Gender-affirming care describes a range of medical interventions that help align people’s bodies with their gender identities. While anyone can seek gender-affirming care in the form of laser hair removal, breast augmentation, erectile dysfunction medication, or hormone therapy, among other treatments, most conversations about gender-affirming care center around transgender people, whose gender identity or gender expression does not conform to their sex assigned at birth.
Gender-affirming care for trans people varies based on age. For example, some trans adults seek hormone replacement therapy (HRT) or gender-affirming surgeries that help their bodies match their internal sense of gender.
Trans kids entering adolescence might be prescribed puberty blockers, which temporarily delay the production of hormones that initiate puberty, to give them more time to figure out their gender identities before deciding on next steps. This is the same medication given to cisgender kids—whose gender identities match the sex they were assigned at birth—experiencing early puberty.
What is gender dysphoria?
Gender dysphoria describes a feeling of unease that some trans people experience when their perceived gender doesn’t match their gender identity. This can lead to a range of mental health conditions that affect their quality of life
Some trans people may manage gender dysphoria by wearing gender-affirming clothing, opting for a gender-affirming hairstyle, or asking others to refer to them by a name and pronouns that authentically represent them. Others may need gender-affirming care to feel at home in their bodies.
Trans people who desire gender-affirming care and have not been able to access it experience psychological distress, including depression, anxiety, self-harm, and suicidal ideation. The Trevor Project’s 2023 U.S. National Survey on the Mental Health of LGBTQ Young People found that roughly half of trans youth “seriously considered attempting suicide in the past year.”
How does gender-affirming care improve mental health?
For trans adults, gender-affirming care can alleviate gender dysphoria, which has been shown to improve both short-term and long-term mental health. A 2018 study found that trans adults who do not undergo HRT are four times more likely to experience depression than those who do, although not all trans people desire HRT.
Extensive research has shown that gender-affirming care also alleviates gender dysphoria and improves mental health outcomes in trans kids, teens, and young adults. A 2022 study found that access to HRT and puberty blockers lowered the odds of depression in trans people between the ages of 13 and 20 by 60 percent and reduced the risk of self-harm and suicidal thoughts by 73 percent.
Both the Endocrine Society—which aims to advance hormone research—and the American Academy of Pediatrics recommend that trans kids and teens have access to developmentally appropriate gender-affirming care.
How can I access gender-affirming care?
If you’re a trans adult seeking gender-affirming care or a guardian of a trans kid or teen who’s seeking gender-affirming care, talk to your health care provider about your options. You can find a trans-affirming provider by searching the World Professional Association for Transgender Health directory or visiting your local LGBTQ+ health center or Planned Parenthood.
Some gender-affirming care may not be covered by insurance. Learn how to make the most of your coverage from the National Center for Transgender Equality. Find insurance plans available through the Marketplace that cover gender-affirming care in some states through Out2Enroll.
Some states restrict or ban gender-affirming care. Learn about the laws in your state by visiting the Trans Legislation Tracker.
Where can trans people and their families find mental health support?
In addition to working with a trans-affirming therapist, trans people and their families can find mental health support through these free services:
- PFLAG offers resources for families and friends of LGBTQ+ people. Find a PFLAG chapter near you.
- The Trevor Project’s hotline has trained counselors who help LGBTQ+ youth in crisis. Call the TrevorLifeline 1-866-488-7386 or text START to 678-678.
- The Trans Lifeline was created by and for the trans community to support trans people in crisis. You can reach the Trans Lifeline hotline at 1-877-565-8860.
For more information, talk to your health care provider.
If you or anyone you know is considering suicide or self-harm or is anxious, depressed, upset, or needs to talk, call the Suicide & Crisis Lifeline at 988 or text the Crisis Text Line at 741-741. For international resources, here is a good place to begin.

The Sardinian Cholesterol Paradox
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.
Broadly speaking, low-density lipoprotein (LDL), or “bad” cholesterol, is generally considered to be… Well… Bad. Specifically because of how it can functionally narrow arteries, causing bits of floating detritus to get stuck in it, narrow it further, and eventually harden into atherosclerotic plaque, at which point it becomes even harder for the body to clear out.
We wrote about the process here: Demystifying Cholesterol
When it comes to cholesterol, the most common lay understanding (especially under a certain age) is “it’s bad”.
A more informed view (and more common after a certain age) is “LDL cholesterol is bad; HDL cholesterol is good”.
A more nuanced view is “LDL cholesterol is established as significantly associated with (and almost certainly a causal factor of) atherosclerotic cardiovascular disease and related mortality in men; in women it is less strongly associated and may or may not be a causal factor”
We wrote more about that, here: Statins: His & Hers? ← despite most research being on men, statins have very different effects (and side effects) for women, often being relatively less useful, and more dangerous. There are exceptions (for some women’s specific profiles they can still be worthwhile), but the trend is certainly troubling.
What, then, of Sardinia?
Sardinia is well-known for being one of the “Supercentenarian Blue Zones”, a place whose inhabitants enjoy (on average, statistically) unusually healthy longevity. These places have been looked to for clues as to how to live the healthiest life.
For example: From Blue To Green: News From The Centenarian Blue Zones
However, researchers recently were investigating life in a region of Sardinia where a lot of people are aged 90+, and followed the health of 168 of them for up to 6 years (because in the case of those who died during that time, obviously the time was less than 6 years).
Note: because this was specifically a Blue Zones study, they only included participants of whom all four grandparents were born within the Blue Zone—so not, for example, looking at the health of someone who just moved there from New York, say.
They collected a lot of interesting data (of course), but what we’re talking about today is that they found that participants with LDL levels above 130 mg/dL had a significantly longer average survival than those with LDL levels below this threshold. Specifically, a 40% lower mortality risk.
This is interesting, because LDL levels ≥130 mg/dL are considered moderate hypercholesterolemia (i.e., the LDL levels are a bit too high).
However, if the same participants had total cholesterol levels over 250mg/dL, they got no extra survival benefits, and very high cholesterol was still linked with shorter survival.
You can read the paper here: The Cholesterol Paradox in Long-Livers from a Sardinia Longevity Hot Spot (Blue Zone)
But before you reach for the butter…
The researchers have several hypotheses about why these results could be so, including:
- The longevity has less to do with LDL itself, and more to do with the diet, with the ratio of grain to olive oil.
- Most of the participants with higher LDL cholesterol were on antihypertensive drugs, which a) will obviously have a cardioprotective effect, and b) means that their heart health is probably enjoying greater scrutiny, and medical scrutiny can also have a protective effect (indeed, that’s the point of it).
- It was also speculated that the locals of that region may have a genetic defense against the harm of moderate hypercholesterolemia, due to historical exposure to malaria meaning that naturally slightly higher cholesterol levels without increased cardiovascular risk may have been naturally selected-for (i.e. those without it were more likely to die of malaria and not pass on their genes).
Thus, it may be that it’s not so applicable more generally. However, it is still reason to at least re-examine how bad LDL cholesterol actually is, and whether for some demographics it could have a protective factor (much like “overweight” BMI is a protective factor for people over 65).
