How Good Is Your Sleep, Really?

Dr. Marie Pierre St. Onge is an expert in sleep behavior and how different dimensions of sleep matter for overall health.

This is Dr. Marie-Pierre St-Onge, Director of Columbia University’s Center of Excellence for Sleep and Circadian Research.

The focus of Dr. St-Onge’s research is the study of the impact of lifestyle, especially sleep and diet, on cardio-metabolic risk factors.

She conducts clinical research combining her expertise on sleep, nutrition, and energy regulation.

What kind of things do her studies look at?

Her work focuses on questions about…

  • The role of circadian rhythms (including sleep duration and timing)
  • Meal timing and eating patterns

…and their impact on cardio-metabolic risk.

What does she want us to know?

First things first, when not to worry:

❝Getting a bad night’s sleep once in a while isn’t anything to worry about. That’s what we would describe as transient insomnia. Chronic insomnia occurs when you spend three months or more without regular sleep, and that is when I would start to be concerned.❞

But… as prevention is (as ever) better than cure, she also advises that we do pay attention to our sleep! And, as for how to do that…

The Six Dimensions of Sleep

One useful definition of overall sleep health is the RU-Sated framework, which assesses six key dimensions of sleep that have been consistently associated with better health outcomes. These are:

  • regularity
  • satisfaction with sleep
  • alertness during waking hours
  • timing of sleep
  • efficiency of sleep
  • duration of sleep

You’ll notice that some of these things you can only really know if you use a sleep-monitoring app. She does recommend the use of those, and so do we!

  • Do we need animal products to be healthy?

    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.

    Do we need animal products to be healthy?

    We asked you for your (health-related) perspective on plant-based vs anima-based foods, and got the above-pictured spread of answers.

    “Some or all of us may need small amounts of animal products” came out on top with more votes than the two more meat-eatery options combined, and the second most popular option was the hard-line “We can all live healthily and happily on just plants”.

    Based on these answers, it seems our readership has quite a lot of vegans, vegetarians, and perhaps “flexitarians” who just have a little of animal products here and there.

    Perhaps we should have seen this coming; the newsletter is “10almonds”, not “10 rashers of bacon”, after all.

    But what does the science say?

    We are carnivores and are best eating plenty of meat: True or False?

    False. Let’s just rip the band-aid off for this one.

    In terms of our anatomy and physiology, we are neither carnivores nor herbivores:

    • We have a mid-length digestive tract (unlike carnivores and herbivores who have short and long ones, respectively)
    • We have a mouthful of an assortment of teeth; molars and premolars for getting through plants from hard nuts to tough fibrous tubers, and we have incisors for cutting into flesh and (vestigial, but they’re there) canines that really serve us no purpose now but would have been a vicious bite when they were bigger, like some other modern-day primates.
    • If we look at our closest living relatives, the other great apes, they are mostly frugivores (fruit-eaters) who supplement their fruity diet with a small quantity of insects and sometimes other small animals—of which they’ll often eat only the fatty organ meat and discard the rest.

    And then, there’s the health risks associated with meat. We’ll not linger on this as we’ve talked about it before, but for example:

    If we avoid processed and/or red meat, that’s good enough: True or False?

    True… Ish.

    Really this one depends on one’s criteria for “good enough”. The above-linked studies, and plenty more like them, give the following broad picture:

    • Red and/or processed meats are unequivocally terrible for the health in general
    • Other mammalian meats, such as from pigs, are really not much better
    • Poultry, on the other hand, the science is less clear on; the results are mixed, and thus so are the conclusions. The results are often barely statistically significant. In other words, when it comes to poultry, in the matter of health, the general consensus is that you can take it or leave it and will be fine. Some studies have found firmly for or against it, but the consensus is a collective scientific shrug.
    • Fish, meanwhile, has almost universally been found to be healthful in moderation. You may have other reasons for wanting to avoid it (ethics, environmentalism, personal taste) but those things are beyond the scope of this article.

    Some or all of us may need small amounts of animal products: True or False?

    True! With nuances.

    Let’s divide this into “some” and “all”. Firstly, some people may have health conditions and/or other mitigating circumstances that make an entirely plant-based diet untenable.

    We’re going light on quotations from subscriber comments today because otherwise this article will get a bit long, but here’s a great example that’s worth quoting, from a subscriber who voted for this option:

    ❝I have a rare genetic disease called hereditary fructose intolerance. It means I lack the enzyme, Aldolase B, to process fructose. Eating fruits and veggies thus gives me severe hypoglycemia. I also have anemia caused by two autoimmune diseases, so I have to eat meat for the iron it supplies. I also supplement with iron pills but the pills alone can’t fix the problem entirely.❞

    And, there’s the thing. Popular vegan talking-points are very good at saying “if you have this problem, this will address it; if you have that problem, that will address it”, etc. For every health-related objection to a fully plant-based diet there’s a refutation… Individually.

    But actual real-world health doesn’t work like that; co-morbidities are very common, and in some cases, like our subscriber above, one problem undermines the solution to another. Add a third problem and by now you really just have to do what you need to do to survive.

    For this reason, even the Vegan Society’s definition of veganism includes the clause “so far as is possible and practicable”.

    Now, as for the rest of us “all”.

    What if we’re really healthy and are living in optimal circumstances (easy access to a wide variety of choice of food), can we live healthily and happily just on plants?

    No—on a technicality.

    Vegans famously need to supplement vitamin B12, which is not found in plants. Ironically, much of the B12 in animal products comes from the animals themselves being given supplements, but that’s another matter. However, B12 can also be enjoyed from yeast. Popular options include the use of yeast extract (e.g. Marmite) and/or nutritional yeast in cooking.

    Yeast is a single-celled microorganism that’s taxonomically classified as a fungus, even though in many ways it behaves like an animal (which series of words may conjure an amusing image, but we mean, biologically speaking).

    However, it’s also not technically a plant, hence the “No—on a technicality”

    Bottom line:

    By nature, humans are quite versatile generalists when it comes to diet:

    • Most of us can live healthily and happily on just plants if we so choose.
    • Some people cannot, and will require varying kinds (and quantities) of animal products.
    • As for red and/or processed meats, we’re not the boss of you, but from a health perspective, the science is clear: unless you have a circumstance that really necessitates it, just don’t.
      • Same goes for pork, which isn’t red and may not be processed, but metabolically it’s associated with the same problems.
    • The jury is out on poultry, but it strongly appears to be optional, healthwise, without making much of a difference either way
    • Fish is roundly considered healthful in moderation. Enjoy it if you want, don’t if you don’t.

  • Patient Underwent One Surgery but Was Billed for Two. Even After Being Sued, She Refused To Pay.

    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.

    Jamie Holmes says a surgery center tried to make her pay for two operations after she underwent only one. She refused to buckle, even after a collection agency sued her last winter.

    Holmes, who lives in northwestern Washington state, had surgery in 2019 to have her fallopian tubes tied, a permanent birth-control procedure that her insurance company agreed ahead of time to cover.

    During the operation, while Holmes was under anesthesia, the surgeon noticed early signs of endometriosis, a common condition in which fibrous scar tissue grows around the uterus, Holmes said. She said the surgeon later told her he spent about 15 minutes cauterizing the troublesome tissue as a precaution. She recalls him saying he finished the whole operation within the 60 minutes that had been allotted for the tubal ligation procedure alone.

    She said the doctor assured her the extra treatment for endometriosis would cost her little, if anything.

    Then the bill came.

    The Patient: Jamie Holmes, 38, of Lynden, Washington, who was insured by Premera Blue Cross at the time.

    Medical Services: A tubal ligation operation, plus treatment of endometriosis found during the surgery.

    Service Provider: Pacific Rim Outpatient Surgery Center of Bellingham, Washington, which has since been purchased, closed, and reopened under a new name.

    Total Bill: $9,620. Insurance paid $1,262 to the in-network center. After adjusting for prices allowed under the insurer’s contract, the center billed Holmes $2,605. A collection agency later acquired the debt and sued her for $3,792.19, including interest and fees.

    What Gives: The surgery center, which provided the facility and support staff for her operation, sent a bill suggesting that Holmes underwent two separate operations, one to have her tubes tied and one to treat endometriosis. It charged $4,810 for each.

    Holmes said there were no such problems with the separate bills from the surgeon and anesthesiologist, which the insurer paid.

    Holmes figured someone in the center’s billing department mistakenly thought she’d been on the operating table twice. She said she tried to explain it to the staff, to no avail.

    She said it was as if she ordered a meal at a fast-food restaurant, was given extra fries, and then was charged for two whole meals. “I didn’t get the extra burger and drink and a toy,” she joked.

    Her insurer, Premera Blue Cross, declined to pay for two operations, she said. The surgery center billed Holmes for much of the difference. She refused to pay.

    Holmes said she understands the surgery center could have incurred additional costs for the approximately 15 minutes the surgeon spent cauterizing the spots of endometriosis. About $500 would have seemed like a fair charge to her. “I’m not opposed to paying for that,” she said. “I am opposed to paying for a whole bunch of things I didn’t receive.”

    The physician-owned surgery center was later purchased and closed by PeaceHealth, a regional health system. But the debt was turned over to a collection agency, SB&C, which filed suit against Holmes in December 2023, seeking $3,792.19, including interest and fees.

    The collection agency asked a judge to grant summary judgment, which could have allowed the company to garnish wages from Holmes’ job as a graphic artist and marketing specialist for real estate agents.

    Holmes said she filed a written response, then showed up on Zoom and at the courthouse for two hearings, during which she explained her side, without bringing a lawyer. The judge ruled in February that the collection agency was not entitled to summary judgment, because the facts of the case were in dispute.

    More From Bill Of The Month

    Representatives of the collection agency and the defunct surgery center declined to comment for this article.

    Sabrina Corlette, co-director of Georgetown University’s Center on Health Insurance Reforms, said it was absurd for the surgery center to bill for two operations and then refuse to back down when the situation was explained. “It’s like a Kafka novel,” she said.

    Corlette said surgery center staffers should be accustomed to such scenarios. “It is quite common, I would think, for a surgeon to look inside somebody and say, ‘Oh, there’s this other thing going on. I’m going to deal with it while I’ve got the patient on the operating table.’”

    It wouldn’t have made medical or financial sense for the surgeon to make Holmes undergo a separate operation for the secondary issue, she said.

    Corlette said that if the surgery center was still in business, she would advise the patient to file a complaint with state regulators.

    The Resolution: So far, the collection agency has not pressed ahead with its lawsuit by seeking a trial after the judge’s ruling. Holmes said that if the agency continues to sue her over the debt, she might hire a lawyer and sue them back, seeking damages and attorney fees.

    She could have arranged to pay off the amount in installments. But she’s standing on principle, she said.

    “I just got stonewalled so badly. They treated me like an idiot,” she said. “If they’re going to be petty to me, I’m willing to be petty right back.”

    The Takeaway: Don’t be afraid to fight a bogus medical bill, even if the dispute goes to court.

    Debt collectors often seek summary judgment, which allows them to garnish wages or take other measures to seize money without going to the trouble of proving in a trial that they are entitled to payments. If the consumers being sued don’t show up to tell their side in court hearings, judges often grant summary judgment to the debt collectors.

    However, if the facts of a case are in dispute — for example, because the defendant shows up and argues she owes for just one surgery, not two — the judge may deny summary judgment and send the case to trial. That forces the debt collector to choose: spend more time and money pursuing the debt or drop it.

    “You know what? It pays to be stubborn in situations like this,” said Berneta Haynes, a senior attorney for the National Consumer Law Center who reviewed Holmes’ bill for KFF Health News.

    Many people don’t go to such hearings, sometimes because they didn’t get enough notice, don’t read English, or don’t have time, she said.

    “I think a lot of folks just cave” after they’re sued, Haynes said.

    Emily Siner reported the audio story.

  • Getting Flexible, Starting As An Adult: How Long Does It Really Take?

    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.

    Aleks Brzezinska didn’t start stretching until she was 21, and here’s what she found:

    We’ll not stretch the truth

    A lot of stretching programs will claim “do the splits in 30 days” or similar, and while this may occasionally be true, usually it’ll take longer.

    Brzezinska started stretching seriously when she was 21, and made significant flexibility gains between the ages of 21 and 23 with consistent practice. Since then, she’s just maintained her flexibility.

    There are facts that affect progress significantly, such as:

    • Anatomy: body structure, age, and joint flexibility do influence flexibility; starting younger and/or having hypermobile joints does make it easier.
    • Consistency: regular practice (2–3 times a week) is crucial, but avoid overdoing it, especially when sore.
    • Lifestyle: weightlifting, running, and similar activities can tighten muscles, making flexibility harder to achieve.
    • Hydration: staying hydrated is important for muscle flexibility.

    She also recommends incorporating a variety of different stretching types, rather than just one method, for example passive stretching, active stretching, Proprioceptive Neuromuscular Facilitation (PNF) stretching, and mobility work.

  • Strawberries vs Raspberries – 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 strawberries to raspberries, we picked the raspberries.

    Why?

    They’re both very respectable fruits, of course! But it’s not even close, and there is a clear winner here…

    In terms of macros, the biggest difference is that raspberries have more than 3x the fiber. Technically they also have twice the protein, but that’s a case of “two times almost nothing is also almost nothing”.

    But still, for the fiber, we’ll call this a clear win for raspberries on macros.

    When it comes to vitamins, raspberries sweep this category. They’re higher in vitamins A, B1, B2, B3, B5, B6, E, K, and also choline, which is sometimes considered a vitamin. Strawberries, meanwhile, boast only a higher vitamin C content.

    All in all, another easy win for raspberries.

    In the category of minerals, guess what, raspberries win this hands-down, too. They’re higher in calcium, copper, iron, magnesium, manganese, phosphorus, and zinc. Strawberries have nothing to boast in this regard.

    Adding up all the individual wins (all for raspberries), it’s not hard to say that raspberries win the day.

  • The Science and Technology of Growing Young – by Sergey Young

    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.

    There are a lot of very optimistic works out there that promise the scientific breakthroughs that will occur very soon. Even amongst the hyperoptimistic transhumanism community, there is the joke of “where’s my flying car?” Sometimes prefaced with “Hey Ray, quick question…” as a nod to (or sometimes, direct address to) Ray Kurzweil, the Google computer scientist and futurist.

    So, how does this one measure up?

    Our author, Sergey Young, is not a scientist, but an investor with fingers in many pies. Specifically, pies relating to preventative medicine and longevity. Does that make him an unreliable narrator? Not necessarily, but it means we need to at least bear that context in mind.

    But, also, he’s investing in those fields because he believes in them, and wants to benefit from them himself. In essense, he’s putting his money where his mouth is. But, enough about the author. What of the book?

    It’s a whirlwind tour of the main areas of reseach and development, in the recent past, the present, and the near future. He talks about problems, and compelling solutions to problems.

    If the book has a weak point, it’s that it doesn’t really talk about the problems to those solutions—that is, what can still go wrong. He’s excited about what we can do, and it’s somebody else’s job to worry about pitfalls along the way.

    As to the “and what you can do now?” We’ll summarize:

    • Mediterranean diet, mostly plant-based
    • Get moderate exercise daily
    • Get good sleep
    • Don’t drink or smoke
    • Get your personal health genomics data
    • Get regular medical check-ups
    • Look after your mental health too

    Bottom line: this is a great primer on the various avenues of current anti-aging research and development, with discussion ranging from the the technological to the sociological. It has some health tips too, but the real meat of the work is the insight into the workings of the longevity industry.

  • Change Your Brain, Change Your Life – by Dr. Daniel G. Amen

    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.

    To what extent can we change our brains, and to what extent are we stuck with what we have?

    Dr. Amen tells us that being mindful of both ends of this is critical:

    • Neuroplasticity means we can, indeed, change our brains
    • We do, however, have fundamental “brain types” based on our neurochemistry and physical brain structure

    He argues for the use of brain imaging technology to learn more about the latter… In order to better go about doing what we can with the former.

    The book looks at how these different brain types can lead to situations where what works as a treatment for one person can often not work for another. It’s also prescriptive, about what sorts of treatments (and lifestyle adjustments) are more likely to do better for each.

    Where the book excels is in giving ideas and pointers for exploration… Things to take to one’s doctor, and—for example—request certain tests, and then what to do with those.

    Where the book is a little light is on including hard science in the explanations. The hard science is referred to, but is considered beyond the scope of the book, or perhaps beyond the interest of the reader. That’s unfortunate, as we’d have liked to have seen more of it, rather than taking claims at face value without evidence.

    Bottom line: this is distinctly “pop science” in presentation, but can give a lot of great ideas for learning more about our own brains and brain health… And then optimizing such.
