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

❝Do we really need pores, and why are they bigger on the face?❞

Pores secrete sweat or sebum (there are different kinds of pores for each).

If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).

If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.

Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).

*Let’s give that its full name though:

Botulinum Neurotoxin Type A in the Treatment of Facial Seborrhea and Acne: Evidence and a Proposed Mechanism

Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.

As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.

If your facial sebaceous glands are too active for your liking…

…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):

The treatment of severe cystic acne with 13-cis-retinoic acid: evaluation of sebum production and the clinical response in a multiple-dose trial

The potential side-effects, however were noted as:

  • Cheilitis
  • Desquamation of the skin
  • Pruritus

Which, in translation from sciencese, means:

  • Chapped lips
  • Flaky skin
  • Itchiness

Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.

Remember when we said what your skin would be like without pores? This is what would happen, only much worse.

Take care!

  • Planning Ahead For Better Sleep

    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.

    Sleep: 6 Dimensions And 24 Hours!

    A woman with dark hair, planning ahead for better sleep, against a white background.

    This is Dr. Lisa Matricciani, a sleep specialist from the University of South Australia, where she teaches in the School of Health Sciences.

    What does she want us to know?

    Healthy sleep begins before breakfast

    The perfect bedtime routine is all well and good, but we need to begin much earlier in the day, Dr. Matricciani advises.

    Specifically, moderate to vigorous activity early in the day plays a big part.

    Before breakfast is best, but even midday/afternoon exercise is associated with better sleep at night.

    Plan your time well to sleep—but watch out!

    Dr. Matricciani’s research has also found that while it’s important to plan around getting a good night’s sleep (including planning when this will happen), allocating too much time for sleep results in more restless sleep:

    ❝Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.❞

    ~ Dr. Lisa Matricciani et al.

    (this was very large study involving 1,168 children and 1.360 adults, mostly women)

    What counts as good sleep quality? Is it just efficiency?

    It is not! Although that’s one part of it. You may remember our previous main feature:

    The 6 Dimensions Of Sleep (And Why They Matter)

    Dr. Matricciani agrees:

    ❝Everyone knows that sleep is important. But when we think about sleep, we mainly focus on how many hours of sleep we get, when we should also be looking at our sleep experience as a whole❞

    ~ Dr. Lisa Matricciani

    Read more: Trouble sleeping? You could be at risk of type 2 diabetes

    That’s not a cheery headline, but here’s her paper about it:

    Multidimensional Sleep and Cardiometabolic Risk Factors for Type 2 Diabetes: Examining Self-Report and Objective Dimensions of Sleep

    And no, we don’t get a free pass on getting less sleep / less good quality sleep as we get older (alas):

    Why You Probably Need More Sleep

    So, time to get planning for the best sleep!

  • Foods That Cause You to Lose Weight – by Dr. Neal Barnard

    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 previously reviewed Dr. Barnard’s “The Power Foods Diet”, and this time his work is about weight loss.

    This time there are more recipes (which take up most of the book, so this one could be reasonably described as a cookbook), but not until after nearly a hundred pages of concepts, principles, and tips.

    The recipes themselves are again very respectable, even if some may be a little redundant (e.g. the double-page recipe for blueberry muffins is followed by a double-page recipe for banana and date muffins, instead of just saying “or substitute this”—things like that) and run the gamut from salad dressings to hearty main meals.

    A strength of the book is that it’s about what you eat, not how much of it you eat, so if you love eating (which is a very healthy trait to have in general), then you’ll enjoy that aspect.

    Bottom line: if you’d like to eat more and weigh less, then this is a top-tier book for you.

  • Native Americans Have Shorter Life Spans. Better Health Care Isn’t the Only Answer.

    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.

    HISLE, S.D. — Katherine Goodlow is only 20, but she has experienced enough to know that people around her are dying too young.

    Goodlow, a member of the Lower Brule Sioux Tribe, said she’s lost six friends and acquaintances to suicide, two to car crashes, and one to appendicitis. Four of her relatives died in their 30s or 40s, from causes such as liver failure and covid-19, she said. And she recently lost a 1-year-old nephew.

    “Most Native American kids and young people lose their friends at a young age,” said Goodlow, who is considering becoming a mental health therapist to help her community. “So, I’d say we’re basically used to it, but it hurts worse every time we lose someone.”

    Native Americans tend to die much earlier than white Americans. Their median age at death was 14 years younger, according to an analysis of 2018-21 data from the Centers for Disease Control and Prevention

    The disparity is even greater in Goodlow’s home state. Indigenous South Dakotans who died between 2017 and 2021 had a median age of 58 — 22 years younger than white South Dakotans, according to state data.

    Donald Warne, a physician who is co-director of the Johns Hopkins Center for Indigenous Health and a member of the Oglala Sioux Tribe, can rattle off the most common medical conditions and accidents killing Native Americans.

    But what’s ultimately behind this low life expectancy, agree Warne and many other experts on Indigenous health, are social and economic forces. They argue that in addition to bolstering medical care and fully funding the Indian Health Service — which provides health care to Native Americans — there needs to be a greater investment in case management, parenting classes, and home visits.

    “It’s almost blasphemy for a physician to say,” but “the answer to addressing these things is not hiring more doctors and nurses,” Warne said. “The answer is having more community-based preventions.”

    The Indian Health Service funds several kinds of these programs, including community health worker initiatives, and efforts to increase access to fresh produce and traditional foods.

    Private insurers and state Medicaid programs, including South Dakota’s, are increasingly covering such services. But insurers don’t pay for all the services and aren’t reaching everyone who qualifies, according to Warne and the National Academy for State Health Policy.

    Warne pointed to Family Spirit, a program developed by the Johns Hopkins center to improve health outcomes for Indigenous mothers and children.

    Chelsea Randall, the director of maternal and child health at the Great Plains Tribal Leaders’ Health Board, said community health workers educate Native pregnant women and connect them with resources during home visits.

    “We can be with them throughout their pregnancy and be supportive and be the advocate for them,” said Randall, whose organization runs Family Spirit programs across seven reservations in the Dakotas, and in Rapid City, South Dakota.

    The community health workers help families until children turn 3, teaching parenting skills, family planning, drug abuse prevention, and stress management. They can also integrate the tribe’s culture by, for example, using their language or birthing traditions.

    The health board funds Family Spirit through a grant from the federal Health Resources and Services Administration, Randall said. Community health workers, she said, use some of that money to provide child car seats and to teach parents how to properly install them to counter high rates of fatal crashes.

    Other causes of early Native American deaths include homicide, drug overdoses, and chronic diseases, such as diabetes, Warne said. Native Americans also suffer a disproportionate number of infant and maternal deaths.

    The crisis is evident in the obituaries from the Sioux Funeral Home, which mostly serves Lakota people from the Pine Ridge Reservation and surrounding area. The funeral home’s Facebook page posts obituaries for older adults, but also for many infants, toddlers, teenagers, young adults, and middle-aged residents.

    Misty Merrival, who works at the funeral home, blames poor living conditions. Some community members struggle to find healthy food or afford heat in the winter, she said. They may live in homes with broken windows or that are crowded with extended family members. Some neighborhoods are strewn with trash, including intravenous needles and broken bottles.

    Seeing all these premature deaths has inspired Merrival to keep herself and her teenage daughter healthy by abstaining from drugs and driving safely. They also talk every day about how they’re feeling, as a suicide-prevention strategy.

    “We’ve made a promise to each other that we wouldn’t leave each other like that,” Merrival said.

    Many Native Americans live in small towns or on poor, rural reservations. But rurality alone doesn’t explain the gap in life expectancy. For example, white people in rural Montana live 17 years longer, on average, than Native Americans in the state, according to state data reported by Lee Enterprises newspapers.

    Many Indigenous people also face racism or personal trauma from child or sexual abuse and exposure to drugs or violence, Warne said. Some also deal with generational trauma from government programs and policies that broke up families and tried to suppress Native American culture.

    Even when programs are available, they’re not always accessible.

    Families without strong internet connections can’t easily make video appointments. Some lack cars or gas money to travel to clinics, and public transportation options are limited.

    Randall, the health board official, is pregnant and facing her own transportation struggles.

    It’s a three-hour round trip between her home in the town of Pine Ridge and her prenatal appointments in Rapid City. Randall has had to cancel several appointments when family members couldn’t lend their cars.

    Goodlow, the 20-year-old who has lost several loved ones, lives with seven other people in her mother’s two-bedroom house along a gravel road. Their tiny community on the Pine Ridge Reservation has homes and ranches but no stores.

    Goodlow attended several suicide-prevention presentations in high school. But the programs haven’t stopped the deaths. One friend recently killed herself after enduring the losses of her son, mother, best friend, and a niece and nephew.

    A month later, another friend died from a burst appendix at age 17, Goodlow said. The next day, Goodlow woke up to find one of her grandmother’s parakeets had died. That afternoon, she watched one of her dogs die after having seizures.

    “I thought it was like some sign,” Goodlow said. “I started crying and then I started thinking, ‘Why is this happening to me?’”

    Warne said the overall conditions on some reservations can create despair. But those same reservations, including Pine Ridge, also contain flourishing art scenes and language and cultural revitalization programs. And not all Native American communities are poor.

    Warne said federal, state, and tribal governments need to work together to improve life expectancy. He encourages tribes to negotiate contracts allowing them to manage their own health care facilities with federal dollars because that can open funding streams not available to the Indian Health Service.

    Katrina Fuller is the health director at Siċaŋġu Co, a nonprofit group on the Rosebud Reservation in South Dakota. Fuller, a member of the Rosebud Sioux Tribe, said the organization works toward “wicozani,” or the good way of life, which encompasses the physical, emotional, cultural, and financial health of the community.

    Siċaŋġu Co programs include bison restoration, youth development, a Lakota language immersion school, financial education, and food sovereignty initiatives.

    “Some people out here that are struggling, they have dreams, too. They just need the resources, the training, even the moral support,” Fuller said. “I had one person in our health coaching class tell me they just really needed someone to believe in them, that they could do it.”

    What Is This Supplement “NALT”?

    N-Acetyl L-Tyrosine (NALT) is a form of tyrosine, an amino acid that the body uses to build other things. What other things, you ask?

    Well, like most amino acids, it can be used to make proteins. But most importantly and excitingly, the body uses it to make a collection of neurotransmitters—including dopamine and norepinephrine!

    • Dopamine you’ll probably remember as “the reward chemical” or perhaps “the motivation molecule”
    • Norepinephrine, also called noradrenaline, is what powers us up when we need a burst of energy.

    Both of these things tend to get depleted under stressful conditions, and sometimes the body can need a bit of help replenishing them.

    What does the science say?

    This is Research Review Monday, after all, so let’s review some research! We’re going to dive into what we think is a very illustrative study:

    A 2015 team of researchers wanted to know whether tyrosine (in the form of NALT) could be used as a cognitive enhancer to give a boost in adverse situations (times of stress, for example).

    They noted:

    ❝The potential of using tyrosine supplementation to treat clinical disorders seems limited and its benefits are likely determined by the presence and extent of impaired neurotransmitter function and synthesis.❞

    More on this later, but first, the positive that they also found:

    ❝In contrast, tyrosine does seem to effectively enhance cognitive performance, particularly in short-term stressful and/or cognitively demanding situations. We conclude that tyrosine is an effective enhancer of cognition, but only when neurotransmitter function is intact and dopamine and/or norepinephrine is temporarily depleted❞

    That “but only”, is actually good too, by the way!

    You do not want too much dopamine (that could cause addiction and/or psychosis) or too much norepinephrine (that could cause hypertension and/or heart attacks). You want just the right amount!

    So it’s good that NALT says “hey, if you need some more, it’s here, if not, no worries, I’m not going to overload you with this”.

    Read the study: Effect of tyrosine supplementation on clinical and healthy populations under stress or cognitive demands

    About that limitation…

    Remember they said that it seemed unlikely to help in treating clinical disorders with impaired neurotransmitter function and/or synthesis?

    Imagine that you employ a chef in a restaurant, and they can’t keep up with the demand, and consequently some of the diners aren’t getting fed. Can you fix this by supplying the chef with more ingredients?

    Well, yes, if and only if the problem is “the chef wasn’t given enough ingredients”. If the problem is that the oven (or the chef’s wrist) is broken, more ingredients aren’t going to help at all—something different is needed in those cases.

    So it is with, for example, many cases of depression.

    See for example: Tyrosine for depression: a double-blind trial

    About blood pressure…

    You may be wondering, “if NALT is a precursor of norepinephrine, a vasoconstrictor, will this increase my blood pressure adversely?”

    Well, check with your doctor as your own situation may vary, but under normal circumstances, no. The effect of NALT is adaptogenic, meaning that it can help keep its relevant neurotransmitters at healthy levels—not too low or high.

    See what we mean, for example in this study where it actually helped keep blood pressure down while improving cognitive performance under stress:

    Effect of tyrosine on cognitive function and blood pressure under stress

    Bottom line:

    For most people, NALT is a safe and helpful way to help keep healthy levels of dopamine and norepinephrine during times of stress, giving cognitive benefits along the way.

  • ADHD For Smart Ass Women – by Tracy Otsuka

    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 reviewed books about ADHD in adults before, what makes this one different? It’s the wholly female focus. Which is not to say some things won’t apply to men too, they will.

    But while most books assume a male default unless it’s “bikini zone” health issues, this one is written by a woman for women focusing on the (biological and social) differences in ADHD for us.

    A strength of the book is that it neither seeks to:

    • over-medicalize things in a way that any deviation from the norm is inherently bad and must be fixed, nor
    • pretend that everything’s a bonus, that we are superpowered and beautiful and perfect and capable and have no faults that might ever need addressing actually

    …instead, it gives a good explanation of the ins and outs of ADHD in women, the strengths and weaknesses that this brings, and good solid advice on how to play to the strengths and reduce (or at least work around) the weaknesses.

    Bottom line: this book has been described as “ADHD 2.0 (a very popular book that we’ve reviewed previously), but for women”, and it deserves that.

  • Fitness Walking and Bodyweight Exercises – by Frank S. Ring

    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.

    A lot of exercise manuals assume that the reader has a “basic” body (nothing Olympian, but nothing damaged either). As we get older, increasingly few of us fall into the “but nothing damaged either” category!

    Here’s where Ring brings to bear his decades of experience as a coach and educator, and also his personal recovery from a serious back injury.

    The book covers direct, actionable exercise advice (with all manner of detail), and also offers mental health tips he’s learned along the way.

    Ring, like us, is a big fan of keeping things simple, so he focusses on “the core four” of bodyweight exercises:

    1. Pushups
    2. Squats
    3. Lunges
    4. Planks

    These four exercises get a whole chapter devoted to them, though! Because there are ways to make each exercise easier or harder, or have different benefits. For example, adjustments include:

    • Body angle
    • Points of contact
    • Speed
    • Pausing
    • Range of motion

    This, in effect, makes a few square meters of floor (and perhaps a chair or bench) your fully-equipped gym.

    As for walking? Ring enjoys and extols the health benefits, and/but also uses his walks a lot for assorted mental exercises, and recommends we try them too.

    A fine book for anyone who wants to gain and/or maintain good health, but doesn’t pressingly want to join a gym or start pumping iron!
