Our favorite French biochemist (Jessie Inchauspé) is back, and this time, she’s tackling a topic near and dear to this writer’s heart: coffee ☕💕

What to consider

Depending on how you like your coffee, some or all of these may apply to you:

  • Is coffee healthy? Coffee is generally healthy, reducing the risk of type 2 diabetes by improving fat burning in the liver and protecting beta cells in the pancreas.
  • Does it spike blood sugars? Usually not so long as it’s black and unsweetened. Black coffee can cause small glucose spikes in some people due to stress-induced glucose release, but only if it contains caffeine.
  • When is it best to drink it? Drinking coffee after breakfast, especially after a poor night’s sleep, can actually reduce glucose and insulin spikes.
  • What about milk? All milks cause some glucose and insulin spikes. While oat milk is generally healthy, for blood sugar purposes unsweetened nut milks or even whole cow’s milk (but not skimmed; it needs the fat) are better options as they cause smaller spikes.
  • What about sweetening? Adding sugar to coffee, especially on an empty stomach, obviously leads to large glucose spikes. Alternative sweeteners like stevia or sweet cinnamon are fine substitutes.

For more details on all of those things, plus why Kenyan coffee specifically may be the best for blood sugars, enjoy:

  • Non-Sleep Deep Rest: A Neurobiologist’s 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.

    How to get many benefits of sleep, while awake!

    Today we’re talking about Dr. Andrew Huberman, a neuroscientist and professor in the department of neurobiology at Stanford School of Medicine.

    He’s also a popular podcaster, and as his Wikipedia page notes:

    ❝In episodes lasting several hours, Huberman talks about the state of research in a specific topic, both within and outside his specialty❞

    Today, we won’t be taking hours, and we will be taking notes from within his field of specialty (neurobiology). Specifically, in this case:

    Non-Sleep Deep Rest (NSDR)

    What is it? To quote from his own dedicated site on the topic:

    What is NSDR (Yoga Nidra)? Non-Sleep Deep Rest, also known as NSDR, is a method of deep relaxation developed by Dr. Andrew Huberman, a neuroscientist at Stanford University School of Medicine.

    It’s a process that combines controlled breathing and detailed body scanning to bring you into a state of heightened awareness and profound relaxation. The main purpose of NSDR is to reduce stress, enhance focus, and improve overall well-being.❞

    While it seems a bit bold of Dr. Huberman to claim that he developed yoga nidra, it is nevertheless reassuring to get a neurobiologist’s view on this:

    How it works, by science

    Dr. Huberman says that by monitoring EEG readings during NSDR, we can see how the brain slows down. Measurably!

    • It goes from an active beta range of 13–30 Hz (normal waking) to a conscious meditation state of an alpha range of 8–13 Hz.
    • However, with practice, it can drop further, into a theta range of 4–8 Hz.
    • Ultimately, sustained SSDR practice can get us to 0.5–3 Hz.

    This means that the brain is functioning in the delta range, something that typically only occurs during our deepest sleep.

    You may be wondering: why is delta lower than theta? That’s not how I remember the Greek alphabet being ordered!

    Indeed, while the Greek alphabet goes alpha beta gamma delta epsilon zeta eta theta (and so on), the brainwave frequency bands are:

    • Gamma = concentrated focus, >30 Hz
    • Beta = normal waking, 13–30 Hz
    • Alpha = relaxed state, 8–13 Hz
    • Theta = light sleep, 4–8 Hz
    • Delta = deep sleep, 1–4 Hz

    Source: Sleep Foundationwith a nice infographic there too

    NSDR uses somatic cues to engage our parasympathetic nervous system, which in turn enables us to reach those states. The steps are simple:

    1. Pick a time and place when you won’t be disturbed
    2. Lie on your back and make yourself comfortable
    3. Close your eyes as soon as you wish, and now that you’ve closed them, imagine closing them again. And again.
    4. Slowly bring your attention to each part of your body in turn, from head to toe. As your attention goes to each part, allow it to relax more.
    5. If you wish, you can repeat this process for another wave, or even a third.
    6. Find yourself well-rested!

    Note: this engagement of the parasympathetic nervous system and slowing down of brain activity accesses restorative states not normally available while waking, but 10 minutes of NSDR will not replace 7–9 hours of sleep; nor will it give you the vital benefits of REM sleep specifically.

    So: it’s an adjunct, not a replacement

    When you’re ready, let Dr. Huberman himself guide you through it in this shortish (10:49) soundtrack:

  • Heal & Reenergize Your Brain With Optimized Sleep Cycles

    Sometimes 8 hours sleep can result in grogginess while 6 hours can result in waking up fresh as a daisy, so what gives? Dr. Tracey Marks explains, in this short video.

    Getting more than Zs in

    Sleep involves 90-minute cycles, usually in 4 stages:

    1. Stage 1: (drowsy state): brief muscle jerks; lasts a few minutes.
    2. Stage 2: (light sleep): sleep spindles for memory consolidation; 50% of total sleep.
    3. Stage 3 (deep sleep): tissue repair, immune support, brain toxin removal via the glymphatic system.
    4. Stage 4 (REM sleep): emotional processing, creativity, problem-solving, and dreaming.

    Some things can disrupt some or all of those. To give a few common examples:

    • Alcohol: impairs REM sleep.
    • Caffeine: hinders deep sleep even if consumed hours before bed.
    • Screentime: delays sleep onset due to blue light (but not by much); the greater problem is that it can also disrupt REM sleep due to mental stimulation.

    To optimize things, Dr. Marks recommends:

    • 90-minute rule: plan sleep to align with full cycles (e.g: 22:30 to 06:00 = 7½ hours, which is 5x 90-minute cycles).
    • Smart alarms: use sleep-tracking apps with built-in alarm, to wake you up during light sleep phases.
    • Strategic naps: keep naps to 20 minutes or a full 90-minute cycle.
    • Pink noise: improves deep sleep.
    • Meal timing: avoid eating within 3 hours of bedtime.
    • Natural light: get morning light exposure in the morning to strengthen circadian rhythm.

    Many of us, in many ways, have more discretionary time than ever… On paper.

    But rather than the 8-hour block of work of yesteryear, nowadays the things that take our time often come in a series of short bursts that punctuate our day.

    This means that while in theory, we have n hours of “free” time per day, we actually have 9 minutes here, 23 minutes there, 1 hour 6 minutes somewhere else, and so on.

    Social commitments, meanwhile, tend to require not only that we have time in a block, but also, that the time around that block also be sufficiently free, for travelling, preparation, etc.

    The result? “We must do this again, and not leave it so long next time!” we say, sincerely, to the friend whom we will next see again in approximately 17 months’ time.

    The problem is how our many theoretically-small obligations reduce the rest of our time to “time confetti”, and that happens on the large scale like we saw above, as well as on the small scale of “Ah, I have an hour to relax between these two things” and then suddenly the time is gone, once again reduced to time confetti:

    Time Confetti and the Broken Promise of Leisure

    So, how to maintain human connection with people beyond those with whom we live?

    Some is infinitely better than none

    Let’s say you want to call a friend or relative. There may be generational differences in how much one is expected to arrange this by text first, vs just calling, but either way, you don’t have to have an open-ended block of time, and sometimes, it’s better if you don’t.

    Establish, at the start of the call, “Before we get into catching up, how are we for time, by the way? For my part, I’ll have to go by such-and-such a time”, and then work with that.

    The benefit of doing this is that you’ll both know enough about the time constraints to use the time appropriately; you won’t run out the clock on smalltalk before getting to something big, and you’ll both come away feeling satisfied that you shared and were shared-with in a meaningful fashion.

    In contrast, guessing at time constraints can leave big things clipped off, or else result in someone “looking for a way to politely end this conversation that stopped being interesting a while ago but it’ll seem rude if I say I have to go now”, of the kind that results in someone not being so open to a call next time.

    Don’t rush to dismiss texts as a medium for meaningful connection

    When text messages were first a thing, you’ll remember how we were all working within a very short character limit and a cost-per-message. It was telegrams for the modern age, basically.

    Nowadays, that isn’t so; we can write as much or as little as we like, and this has two benefits:

    1. We can have longer, meaningful conversations around the other stuff in our life. We can reply in seconds, or after making a cup of tea and thinking about it, or after our grocery-chopping trip, or whenever suits us. Suddenly, time confetti isn’t such a barrier to human connection. Writer’s example: my prime social time in this manner is when I’m cooking dinner (which is often about an hour). There’s no way I could have a phonecall while doing that; my bad hearing notwithstanding, I just have my hands full too often with much else going on. But texting? I can do that in the several-minute gaps between assorted culinary tasks, while I’m waiting for the kettle to boil or the onions to brown or whatever.
    2. Sometimes, the brevity makes it easier. A quick text saying “Hey, just to let you know I’m thinking of you, and hope your day is going well!”, or “Unrelated to anything: I was just thinking about how I’m glad to have you in my life; you’re a good friend, and I appreciate that more than I often remember to say. Anyway, that’s all; it was just on my mind. I hope your day is going well!”

    (The cheery closing words in those last two text message examples help signify: “don’t worry, I’m fine and am not looking for anything from you”, which will help the recipient to relax, and counterintuitively, more likely to reply with some kind words of their own, knowing that they’re not signing up for a potentially deep talk when they also have time confetti issues going on)

    Seize the moment (and also let it go)

    You probably have many small interactions with strangers, most days. In the store, walking the dog, at the doctor’s office, etc. So, two things:

    1. Make smalltalk. And if you’re not one for traditional smalltalk topics (weather etc), or even if you are, a level-up is:
    2. Compliment sincerely. Straight out of “How To Win Friends And Influence People”, of course, but it creates a moment of genuine connection; you say a thing, their day is improved, they smile, you complete your business with a smile of your own and go about your day.

    (of course, do steer clear of anything that could be interpreted as flirting, if that is not your intent, and really it should never be your intent when it comes to the captive audience of someone who will get fired if they’re not nice to you)

    But, with a little practice, these little moments add up to a lot more human connection than if we treat the strangers with whom we interact as though they were merely part of the scenery.

  • One More Resource Against Osteoporosis!

    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.

    Your Bones Were Made For Moving Too!

    We know that to look after bone health, resistance training is generally what’s indicated. Indeed, we mentioned it yesterday, and we’ve talked about it before:

    Resistance Is Useful! (Especially As We Get Older)

    We also know that if you have osteoporosis already, some exercises are a better or worse idea than others:

    Osteoporosis & Exercises: Which To Do (And Which To Avoid)

    However! New research suggests that also getting in your recommended 150 minutes per week of moderate exercise slows bone density loss.

    The study by Dr. Tiina Savikangas et al. looked at 299 people in their 70s (just over half being women) and found that, over the course of a year, bone mineral density loss was inversely correlated with moderate exercise as recorded by an accelerometer (as found in most fitness-tracking wearables and smartphones).

    In other words: those who got more minutes of exercise, kept more bone mineral density.

    As well as monitoring bone mineral density, the study also looked at cross-sectional area, but that remained stable throughout.

    As for how much is needed:

    ❝Even short bursts of activity can be significant for the skeleton, so we also looked at movement in terms of the number and intensity of individual impacts. For example, walking and running cause impacts of different intensities.

    We found that impacts that were comparable to at least brisk walking were associated with better preservation of bone mineral density.❞

    ~ Dr. Tiina Savikangas

    On which note, we’ve a small bone to pick…

    As a small correction, the pop-science source says that the subjects’ ages ranged from 70 to 85 years; the paper, meanwhile, clearly shows that the age-range was 74.4±3.9 years (shown in the “Results” table), rounded to 74.4 ± 4 years, in the abstract. So, certainly no participant was older than 78 years and four months.

    Why this matters: the age range itself may be critical or it might not, but what is important is that this highlights how we shouldn’t just believe figures cited in pop-science articles, and it’s always good to click through to the source!

    Read the study: Changes in femoral neck bone mineral density and structural strength during a 12-month multicomponent exercise intervention among older adults – Does accelerometer-measured physical activity matter?

    This paper is a particularly fascinating read if you have time, because—unlike a lot of studies—they really took great care to note what exactly can and cannot be inferred from the data, and how and why.

    Especially noteworthy was the diligence with which they either controlled for, or recognized that they could not control for, far more variables than most studies even bother to mention.

    This kind of transparency is critical for good science, and we’d love to see more of it!

    Want to apply this to your life?

    Tracking minutes-of-movement is one of the things that fitness trackers are best at, so connect your favourite app (one of these days we’ll do a fitness tracker comparison article) and get moving!

  • 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.
