The Other Circadian Rhythms

We’ve talked before about how circadian rhythm pertains not just to when it is ideal for us to sleep or be awake, but also at what times it is best to eat, exercise, and so forth:

The Circadian Rhythm: Far More Than Most People Know

Most people just know about the light consideration, per for example:

When your body parts clock on and off at the wrong time…

Now, new research has brought attention to how these things and more are governed by different physiological clocks within our bodies—and what this means for our health. In other words, if you are doing the various things at different times than you “should”, you will be training the different parts of your body (each with their independent clocks) to be on a different schedule, and so the different parts of your body will out of temporal sync with each other.

To put this in jet-lag terms: if your brain is in New York, while your heart is in Istanbul (not Constantinople) and your gut is in Tokyo, then this arrangement is not good for the health.

As for how it is not good for your health (i.e. the consequences) there’s still research to be done on some of the longer-term implications, but in the short term, one of the biggest effects is on our mood—most notably, increasing depression scores significantly.

And even more importantly, this is in the real world. That is to say, until quite recently, most data we had from studies on the circadian rhythm was from sleep clinic laboratories, which is great for RCTs but will always have as a limitation that someone sleeping in a lab is going to have some differences than someone sleeping in their own bed at home.

As the researchers said:

❝A critical step to addressing this is the noninvasive collection of physiological time-series data outside laboratory settings in large populations. Digital tools offer promise in this endeavor. Here, using wearable data, we first quantify the degrees of circadian disruption, both between different internal rhythms and between each internal rhythm and the sleep-wake cycle. Our analysis, based on over 50,000 days of data from over 800 first-year training physicians, reveals bidirectional links between digital markers of circadian disruption and mood both before and after they began shift work, while accounting for confounders such as demographic and geographic variables. We further validate this by finding clinically relevant changes in the 9-item Patient Health Questionnaire score.❞

That questionnaire by the way sounds like an arbitrary thing they just made up, but the PHQ-9 (as it is known to its friends) is in fact the current intentional gold standard for measuring depression; we share it at the top of our article about depression, here:

    A recent UK-based survey found that…

    • while nearly half of adults say dementia is the disease they fear most,
    • only a third of those thought you could do anything to avoid it, and
    • just 1% could name the 7 known risk factors.

    Quick test

    Can you name the 7 known risk factors?

    Please take a moment to actually try (this kind of mental stimulation is good in any case), and count them out on your fingers (or write them down), and then

    Answer (no peeking if you haven’t listed them yet)

    The 7 known risk factors are:

    *drumroll please*

    1. Smoking
    2. High blood pressure
    3. Diabetes
    4. Obesity
    5. Depression
    6. Lack of mental stimulation
    7. Lack of physical activity

    How many did you get? If you got them all, well done. If not, then well, now you know, so that’s good.

  • How To Keep On Keeping On?

    How To Keep On Keeping On… Long Term!

    For many when it comes to health-related goals and practices, it’s easy to find ourselves in a bit of a motivational dip around this time of year. The enthusiasm of new year’s resolutions has been and gone, and there’s not yet much of a drive to “get a beach body” or “be summer-ready”.

    A word to the wise on those before moving on, though:

    • How to get a beach body: take your body to a beach. Voilà. Beach body.
      • Remember: the beach is there for your pleasure and entertainment, not the other way around!
    • How to be summer-ready: the real question is, will summer be ready for you?

    But what is this, demotivational rhetoric to discourage you from getting fit and healthy?

    Not at all, but rather, to be sure that you’re pursuing your own goals and not just what you feel might be expected of you.

    All that in mind, let’s get to the tips…

    Focus on adding health

    It can be tempting (and even, good) to cut down on unhealthy things. But when it comes to motivation, it’s harder to stay motivated for deprivation, than it is for some healthy addition to life.

    So for example, this philosophy would advocate for:

    • Instead of counting calories, count steps! Or even…
    • Instead of counting calories, count colors! Eat the rainbow and all that. No, skittles do not count, but eating a variety of naturally different-colored foods will tend to result in adding different nutrients to your diet.
    • Instead of cutting out sugar, add fruit! How many per day will you go for? If you don’t eat much fruit as it is, consider making it a goal to have even just one piece of fruit a day, then build up from there. Find fruit you like! If you pick the fruit you want instead of the fruit you think you “should” have, it’s basically a dessert snack.

    We’ve recommended it before, and we’ll recommend it again, but if you’re interested in “adding health”, you should definitely check out:

    Dr. Greger’s Daily Dozen (checklist, plus app if you want it)

    More details: it’s a checklist of 12 things you should try to include in your diet, with a free streak-tracking app, if you want it, all based on the same scientific research as the best-selling book “How Not To Die”.

    “Minimum effort!”

    Did you see the movie “Deadpool”? The protagonist has a catch-phrase as he goes into battle, saying to himself “Maximum effort!”.

    And, that’s all very well and good if your superpower is immediate recovery from pretty much anything, but for the rest of us, sometimes it’s good to hold ourselves to “minimum effort!”.

    Sometimes, something worth doing is worth doing just a little a bit. It’s always better than nothing! Even if feels like you gained nothing from it, it’s the foundation of a habit, and the habit will grow and add up. Sometimes it may even take you by surprise…

    Don’t feel like doing 20 bodyweight squats? Do literally just one. Make a deal with yourself: do just one, then you can stop if you like. Then after you’ve done one, you might think to yourself “huh, that wasn’t so bad”, and you try out a few more. Maybe after 5 you can feel your blood pumping a bit and you think “you know what, that’s enough for now”, and great, you did 5x as much exercise as you planned! Wonder what you’ll do tomorrow!

    (personal note from your writer here: I’ve managed to “just extend this exercise a little bit more than last time” my way into hour-long exercise sessions before now; I started with “just 10 squats” or “just one sun salutation” etc, to get myself out of a no-exercise period that I’d slipped into, and it’s amazing how quickly adding just a little bit to the previous day’s “minimum effort!” adds up to a very respectable daily exercise session)

    Wondering what a good, easy, respectable short term goal could be?

    Check Out, For Example: The Seven-Minute Workout

    (You might have heard of this one before; it’s an incredibly efficient well-optimized short complete workout that requires no special equipment, just a bit of floorspace and a wall—the above app allows for customizations of it per your preferences, but the basic routine is an excellent starting point for most people)

    Commit to yourself (and do any self-negotiation up-front)

    Really commit, though. No “or I will look silly because I told people I’d do it”, no “or I will donate x amount to charity” etc, just “I will do it and that’s that”. If you find yourself second-guessing yourself or renegotiating with yourself, just shut that down immediately and refuse to consider it.

    Note: you should have break-clauses in this contract with yourself, though. For example, “unless I am ill or injured” is a sensible rule to have in advance for most exercise regimes that weren’t undertaken with your illness or injury in mind.

    Make a “To-Don’t” list

    Much like how addicts are often advised to not try to quit more than one thing at once, we must also be mindful of not taking on too much at once. It can be very tempting to think:

    “I will turn my life around, now! I’ll quit alcohol and animal products and sugar and refined grains, and I’ll go for a run each morning, and I’ll do this and that and there, I’ve got it, here is the blueprint for my healthy perfect life from this day forth!”

    And, it’s great to have any and all of that as your end goal if you want, but please, pick one or two things at most to start with, focus on those, and when those have become second nature to you and just a normal part of your life, then choose the next thing to work on.

    (You can plan out the whole thing in advance if you want! i.e., I’ll do this, then this, then this, but just… make sure that you’ve really got each one down to a matter of comfort and ease before you take up the next one)

    In summary:

    • Focus on adding health, whatever that looks like to you
    • Figure out what “minimum effort!” is for you, and let that be your baseline
    • Commit to yourself (and do any self-negotiation up-front, not later)
    • Decide what you’re not going to do yet, and stick to that, too.

  • Planning Festivities Your Body Won’t Regret

    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.

    The Festive Dilemma

    For many, Christmas is approaching. Other holidays abound too, and even for the non-observant, it’d be hard to escape seasonal jollities entirely.

    So, what’s the plan?

    1. Eat, drink, and be merry, and have New Year’s Resolutions for the first few days of January before collapsing in a heap?
    2. Approach the Yuletide with Spartan abstemiousness and miss all the fun while simultaneously annoying your relatives?

    Let’s try to find a third approach instead…

    What’s festive and healthy?

    We’re doing this article this week, because many people will be shopping already, making plans, and so forth. So here are some things to bear in mind:

    Make your own mindful choices

    Coca-Cola company really did a number on Christmas, but it doesn’t mean their product is truly integral to the season. Same goes for many other things that flood the stores around this time of year. So much sugary confectionary! But remember, they’re not the boss of you. If you wouldn’t buy it ordinarily, why are you buying it now? Do you actually even want it?

    If you really do, then you do you, but mindful choices will invariably be healthier than “because there were three additional aisles of confectionary now so I stopped and looked and picked some things”.

    Pick your battles

    If you’re having a big family gathering, likely there will be occasions with few healthy options available. But you can decide what’s most important for you to avoid, perhaps picking a theme, e.g:

    • No alcohol this year, or
    • No processed sugary foods, or
    • Eat/drink whatever, but practice intermittent fasting

    Some resources:

    Fight inflammation

    This is a big one so it deserves its own category. In the season of sugar and alcohol and fatty meat, inflammation can be a big problem to come around and bite us in the behind. We’ve written on this previously:

    Keep Inflammation At Bay

    Positive dieting

    In other words, less of a focus on what to exclude, and more of a focus on what to include in your diet. Fruity drinks and sweets are common at this time of year, but you know what’s also fruity? Fruit!

    And it can be festive, too! Berries are great, and those tiny orange-like fruits that may be called clementines or tangerines or satsumas or, as Aldi would have it, “easy peelers”. Apple and cinnamon are also a great combination that both bring sweetness without needing added sugar.

    And as for mains? Make your salads that bit fancier, get plenty of greens with your main, have hearty soups and strews with lentils and beams!

    Your gut will thank us later!

    Get moving!

    That doesn’t mean you have to beat the New Year rush to the gym (unless you want to!). But it could mean, for example, more time in your walking shoes (or dancing shoes! With a nod to today’s sponsor) and less time in the armchair.

    See also: The doctor who wants us to exercise less; move more

    Lastly…

    Remember it’s supposed to be fun! And being healthy can be a lot more fun than suffering because of unfortunate choices that we come to regret.

    Take care!

    It’s Q&A Day at 10almonds!

    Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!

    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

    ❝Doctors are great at saving lives like mine. I’m a two time survivor of colon cancer and have recently been diagnosed with Chron’s disease at 62. No one is the health system can or is prepared to tell me an appropriate diet to follow or what to avoid. Can you?❞

    Congratulations on the survivorship!

    As to Crohn’s, that’s indeed quite a pain, isn’t it? In some ways, a good diet for Crohn’s is the same as a good diet for most other people, with one major exception: fiber

    …and unfortunately, that changes everything, in terms of a whole-foods majority plant-based diet.

    What stays the same:

    • You still ideally want to eat a lot of plants
    • You definitely want to avoid meat and dairy in general
    • Eating fish is still usually* fine, same with eggs
    • Get plenty of water

    What needs to change:

    • Consider swapping grains for potatoes or pasta (at least: avoid grains)
    • Peel vegetables that are peelable; discard the peel or use it to make stock
    • Consider steaming fruit and veg for easier digestion
    • Skip spicy foods (moderate spices, like ginger, turmeric, and black pepper, are usually fine in moderation)

    Much of this latter list is opposite to the advice for people without Crohn’s Disease.

    *A good practice, by the way, is to keep a food journal. There are apps that you can get for free, or you can do it the old-fashioned way on paper if prefer.

    But the important part is: make a note not just of what you ate, but also of how you felt afterwards. That way, you can start to get a picture of patterns, and what’s working (or not) for you, and build up a more personalized set of guidelines than anyone else could give to you.

    We hope the above pointers at least help you get going on the right foot, though!

    ❝Why do baked goods and deep fried foods all of a sudden become intolerable? I used to b able to ingest bakery foods and fried foods. Lately I developed an extreme allergy to Kiwi… what else should I “fear”❞

    About the baked goods and the deep-fried foods, it’s hard to say without more information! It could be something in the ingredients or the method, and the intolerance could be any number of symptoms that we don’t know. Certainly, pastries and deep-fried foods are not generally substantial parts of a healthy diet, of course!

    Kiwi, on the other hand, we can answer… Or rather, we can direct you to today’s “What’s happening in the health world” section below, as there is news on that front!

  • Do You Have A Personalized Health Plan? (Here’s How)

    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.

    “Good health” is quite a broad umbrella, and while we all have a general idea of what “healthy” looks like, it’s easy to focus on some areas and overlook others.

    Of course, how much one does this will still depend on one’s level of interest in health, which can change over the course of life, and (barring serious midlife health-related curveballs such as a cancer diagnosis or something) often looks like an inverse bell curve:

    • As small kids, we probably barely thought about health
    • As teenagers, we probably had a narrow view of health (often related to whatever is considered sexually attractive at the time)
    • In our 20s, may have a bit of a health kick in which we learn and apply a lot… Which often then gets to later take a bit of a back seat to work responsibilities and so forth
    • This is commonly followed by a few decades of just trying to make it to Friday by any means necessary (definite risk factor for substance abuse of various kinds), double if we have kids, triple if we have work, kids, and are also solely responsible for managing the household.
    • Then just as suddenly as it is predictably, we are ambushed when approaching retirement age by a cluster of age-related increased health risks that we now get to do our best to mitigate—the focus here is “not dying early”. A lot of health education occurs at this time.
    • Finally, upon retirement, we actually get the time to truly focus on our health again, and now it’s easier to learn about all aspects of health, even if now there’s a need to juggle many health issues all at once, most of which affect the others.

    See also: How Likely Are You To Live To 100? ← in which we can also see a graph of 10almonds subscribers’ ages, consistent with the above

    So, let’s recap, and personalize our health plan

    There are often things we wish we could have focused on sooner, so now’s the time to figure out what future-you in your next decade (or later!) is going to thank you for having done now.

    So, while 20-year-old us might have been focusing on fat levels or athletic performance, how much does that really help us now? (With apologies to any readers in their 20s, but also, with the bonus for you: now’s the perfect time to plan ahead!)

    At 10almonds, while we cover very many health topics, we often especially focus on:

    • Brain health
    • Heart health
    • Gut health

    …because they affect everything else so much. We’ve listed them there in the order they appear in the body, but in fact it can be useful to view them upside down, because:

    • Gut health is critical for good metabolic health (a happy efficient gut allows us to process nutrients, including energy, efficiently)
    • Metabolic health is critical for good heart health (a nicely ticking metabolism will not strain our heart)
    • Heart health is critical for good brain health (a strong heart will nourish the brain with well-oxygenated blood and the nutrients it also carries)

    So, this isn’t a catch-22 at all! There is a clear starting point:

    Stop Sabotaging Your Gut

    “How do I do the other bits, though?”

    We have you covered here: Your Health Audit, From Head To Toe

    “Wait, where’s the personalization?”

    This comes once you’ve got those above things in order.

    Hopefully you know what particular health risks you have—as in, particular to you.

    First, you will have any current diagnoses, and a plan for treating those. Many chronic illnesses can be reversed or at least lessened with lifestyle changes, in particular, if we reduce chronic inflammation, which is implicated in countless chronic illnesses, and exacerbates most of the rest.

    So: How to Prevent (or Reduce) Inflammation

    The same goes for any heightened risks you have as a result of those current diagnoses.

    Next, you will have any genetic health risks—so here’s where genetic testing is a good one-shot tool, to get a lot of information all in one go.

    Learn more: The Real Benefit Of Genetic Testing

    …and then, of course, take appropriate steps to avoid suffering the things of which you are at increased genetic risk.

    Finally, you will have any personal concerns or goals—in other words, what do you want to still be able to do, later in life? It’s easy to say “everything”, but what’s most important?

    This writer’s example: I want to remain mobile, free from pain, and sharp of mind.

    That doesn’t mean I’ll neglect the rest of my health, but it does mean that I will regularly weigh my choices against whether they are consistent with those three things.

    As for how to plan for that?

    Check out: Train For The Event Of Your Life! ← this one is mostly about the mobility aspect; staying free from pain is in large part a matter of avoiding inflammation which we already discussed, and staying sharp of mind relies on the gut-heart-brain pipeline we also covered.

    You can also, of course, personalize your diet per which areas of health are the most important for you:

  • Apple Cider Vinegar vs Balsamic Vinegar – 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 apple cider vinegar to balsamic vinegar, we picked the apple cider vinegar.

    Why?

    It’s close! And it’s a simple one today and they’re both great. Taking either for blood-sugar-balancing benefits is fine, as it’s the acidity that has this effect. But:

    • Of the two, balsamic vinegar is the one more likely to contain more sugars, especially if it’s been treated in any fashion, and not by you, e.g. made into a glaze or even a reduction (the latter has no need to add sugar, but sometimes companies do because it is cheaper—so we recommend making your own balsamic vinegar reduction at home)
    • Of the two, apple cider vinegar is the one more likely to contain “the mother”, that is to say, the part with extra probiotic benefits (but if the vinegar has been filtered, it won’t have this—it’s just more common to be able to find unfiltered apple cider vinegar, since it has more popular attention for its health benefits than balsamic vinegar does)

    So, two wins for apple cider vinegar there.
