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:
- How light can shift your mood and mental health, and
- How light tells you when to sleep, focus and poo
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:

Egg Whites vs Whole Eggs – 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 egg whites to whole eggs, we picked the whole eggs.
Why?
Egg whites are mostly protein. Egg yolks are mostly fat, with some protein.
However, fat ≠ bad, and the yolk is also where the choline is stored, which itself (as well as its benefits for your brain) will tend to reduce fat storage in the body.
Furthermore, the yolk contains an assortment of vitamins, minerals, and essential amino acids. After all, the yolk is there specifically to contain everything needed to turn a cluster of cells into a small bird.

Winter Wellness – by Rachel de Thample
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.
Winter is often the season of comfort foods and, in much of the Western world, there’s a holiday season slide of forgotten diets and instead sugar, alcohol, pastry, and the like.
What de Thample does here is an antidote to all that, without sacrificing happiness and celebration.
Before the recipes get started, she has a chapter on “food as medicine“, and to our immense surprise, proceeds to detail, accurately, many categories such as
- Foods for immune health
- Foods against inflammation
- Foods for gut health
- Foods against aging
- Foods for energy levels
- Foods against anxiety
- Foods for hormonal balance
…and so forth, with lists of ingredients that fit into each category.
Then in the rest of the book, she lays out beautiful recipes for wonderful dishes (and drinks) that use those ingredients, without unhealthy additions.
The recipes are, by the way, what could best be categorized as “fancy”. However, they are fancy in the sense that they will be impressive for entertaining, and (again, to our great surprise) they don’t actually call for particularly expensive/rare ingredients, nor for arcane methods and special equipment.Instead, everything’s astonishingly accessible to put together and easy to execute.
Bottom line: if you’d like to indulge this winter, but would like to do so healthily, this is an excellent way to do so.

Tech Bliss – by Clo S., MSc.
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 popular idea of a “digital detox” is simple enough, “just unplug!”, they say.
But here in the real world, not only is that often not practical for many of us, it may not always even be entirely desirable. The Internet (and our devices with all their bells and whistles) can be a source of education, joy, and connection!
So, how to find out what’s good for us and what’s not, in our daily digital practices? Clo. S. has answers… Or rather, experiments for us to do and find out for ourselves.
These experiments range from the purely practical “try this to streamline your experience” to the more personal “how does this thing make you feel?”. A lot of the experiments will be performed via your digital devices—some, without! Others are about online interpersonal dynamics, be they one-on-one or navigating a world in which it seems everyone is out to get us, our outrage, and/or our money. Still yet others are about optimizing what you do get from the parts of your digital experience that are enriching for you.
As the title suggests, there are 30 experiments, and it’s not a stretch to do them one per day for a month. But, as the author notes, it’s by no means necessary to do them like that; it’s a workbook and reference guide, not a to-do list!
(On the topic of it being a reference guide…There’s also an extensive tools directory towards the end!)
In short: this is a great book for optimizing your online experience—whatever that might mean for you personally; you can decide for yourself along the way!

You’ve Got Questions? We’ve Got Answers!
Q: Tips for reading more and managing time for it?
A: We talked about this a little bit in yesterday’s edition, so you may have seen that, but aside from that:
- If you don’t already have one, consider getting a Kindle or similar e-reader. They’re very convenient, and also very light and ergonomic—no more wrist strain as can occur with physical books. No more eye-strain, either!
- Consider making reading a specific part of your daily routine. A chapter before bed can be a nice wind-down, for instance! What’s important is it’s a part of your day that’ll always, or at least almost always, allow you to do a little reading.
- If you drive, walk, run, or similar each day, a lot of people find that’s a great time to listen to an audiobook. Please be safe, though!
- If your lifestyle permits such, a “reading retreat” can be a wonderful vacation! Even if you only “retreat” to your bedroom, the point is that it’s a weekend (or more!) that you block off from all other commitments, and curl up with the book(s) of your choice.

The Disordered Mind – by Dr. Eric Kandel
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 don’t generally include author bios in these reviews, but it’s worth mentioning that Dr. Kandel won the Nobel Prize in Physiology/Medicine, for studies related to the topics in this book.
The premise in this book is as per the subtitle: what unusual brains tell us about ourselves. He assumes that the reader has a “usual” brain, but if you don’t, then all is not lost, and in fact he probably talks about your brain in the book too.
Examining the brains of people with conditions ranging from autism to Alzheimer’s, schizophrenia to Parkinson’s, or even such common things as depression and anxiety and addiction, tells us a lot about what in our brain (anatomically and physiologically) is responsible for what, and how those things can be thrown out of balance.
By inference, that also tells us how to keep things from being thrown out of balance. Even if the genetic deck is stacked against you, there are still things that can be done to avoid actual disease. After all, famously, “genes load the gun, but lifestyle pulls the trigger”.
Dr. Kandel writes in a clear and lucid fashion, such that even the lay reader can quite comfortably learn about such things as prion-folding and inhibitory neurons and repressed transcription factors and more.
Bottom line: if you’d like to understand more about what goes wrong and how and why and what it means for your so-far-so-good healthy brain, this is the book for that.

Does PRP Work For Hair Loss?
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.
Dr. Ankit Gupta takes us through the details of this hair loss remedy for androgenic alopecia.
The bald truth
Platelet-Rich Plasma (PRP) is a controversial treatment for androgenic hair loss.
What it involves: blood is drawn and separated using a centrifuge. PRP—including growth proteins and hormones—is extracted from the blood; about 30 ml of blood is needed to produce 5 ml of PRP. This is then injected directly into the scalp. As this can be painful, local anaesthetic is sometimes used first. This usually involves monthly sessions for the first 3 months, then booster sessions every 3–6 months thereafter.
Does it work? Research is young; so far 60% of trials have found it worked; 40% found it didn’t. When it works, effectiveness (in terms of hair restoration) is considered to be between 25–43%. Results are inconsistent and seem to vary from person to person.
In short, this doctor’s recommendation is to consider it after already having tried standard treatments such as finasteride and/or minoxidil, as they are more likely to work and don’t involve such exciting procedures as injecting your own blood extracts back into your head.
