Beyond “sleep hygiene”, Dr. Siobhan Deshauer has insights to share:
Rest for your body and mind
First, do still do the basics. That means dimming/filtering lights for an hour before bed, lowering the room temperature a little, ensuring you have nice fresh sheets, not having alcohol or caffeine before bed, and getting out of bed if you’re not asleep within half an hour, to avoid associating being in bed with wakefulness.
Next, the extra tips:
- Progressive relaxation: tense and relax each muscle group from toes to head
- Box breathing: inhale, hold, exhale, and hold for 4 seconds each; helps calm the nervous system (it’s called “box breathing” because of the 4:4:4:4 setup)
- Diaphragmatic breathing: focus on belly breathing, with longer exhalation to activate the parasympathetic nervous system (note that this can, and even ideally should, be done at the same time as the previous)
- Cognitive shuffling: think of words starting with each letter of a chosen word while visualizing them (this is like “counting sheep”, but does the job better—the job in question being preventing your brain from moving to anything more strenuous or stressful)

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
❝I live in a large city and even late at night there is always a bit of background noise. While I am pretty used to it by now, I find I don’t sleep nearly as well in the city as I do in the country. I have seen some stuff about “white noise” generators. I was wondering whether you have any thoughts about the science behind these, and whether it is something I should try out – or maybe I should be trying something completly different.❞
The science says…
❝Our data show that white noise significantly improved sleep based on subjective and objective measurements in subjects complaining of difficulty sleeping due to high levels of environmental noise. This suggests that the application of white noise may be an effective tool in helping to improve sleep in those settings.❞
That said, you might also consider “pink noise”, which is very similar to white noise (having all frequencies normally audible to the human ear), but has greater intensity of lower frequencies, creating a more deep and even sound. While white noise and pink noise are both great at “muting” external sounds like those that have been disturbing your sleep, pink noise may have an advantage in helping to stimulate deep and restful sleep:
❝This study demonstrates that steady pink noise has significant effect on reducing brain wave complexity and inducing more stable sleep time to improve sleep quality of individuals.❞

Dr. Dean Ornish’s Program For Reversing Heart Disease – by Dr. Dean Ornish
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 previously reviewed Dr. Ornish’s “Undo It!” which is about reversing many kinds of chronic diseases (not all, alas, but quite a few) by undercutting their common etiologies, such as inflammation, insulin resistance, and so forth.
This book is entirely consistent with that one, but the focus here is (as the title says) specifically on reversing heart disease.
Of course, it does not require you to already have heart disease—if you do, well, getting onto this is better sooner than later. If you don’t, and are “merely” in a risk zone, or even just want to be proactive about your heart health, then this book will stand you in good stead.
The book covers all the lifestyle things you’d expect it to (especially diet, but also exercise, and not just “quit smoking” but also how, things like that), and possibly some things you might not expect (chapters on more psychological factors that have a big impact on heart health).
There are recipes (157 pages of them; they are plant-based and good) and there is a 21-day meal plan to get you going.
The style is a little dated (written in the 90s), but the content doesn’t suffer for it, having been updated over the years in any case.
Bottom line: if you want a holistic approach to taking care of your heart that’s not extreme and/but is very effective, then well, you’ve found it.

90% Of People Skip This Essential Exercise—Are You One Of Them?
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.
Single-leg strengthening is essential for joint health at any age (unless you want to bunny-hop up and down the stairs with both feet at once, for example), yet many people overlook it. This neglect often leads to pain, stiffness, and a higher risk of injury.
Dr. Alyssa Kuhn, arthritis specialist, explains how to do it:
On the rise
In this video, different exercise variations—beginner, intermediate, and advanced—are presented to help you build strength at your own pace:
Beginner: start by using a chair, adding a cushion for support if needed. Sit at the edge and position one foot slightly in front of the other in a staggered stance. Stand up and sit down in a controlled manner, allowing the back leg to bear more weight and work harder than the front leg. Do 8–10 repetitions per side and pay attention to whether one side feels weaker. To build strength, incorporate this movement into daily activities, such as standing up from the couch. Master this variation before progressing, to avoid knee injury.
Intermediate: to make the exercise more challenging, you can either use a lower chair, or extend your front foot further out, shifting more weight to your back leg. Only modify one variable at a time to maintain control. Do 8–10 repetitions per side, ensuring proper form. A common mistake is allowing the back knee to move inward, which can cause knee stress. To prevent this, use a mirror to check your form and keep the knee and ankle aligned during movement.
Advanced: when you’re ready, extend your front leg completely with the heel on the ground and toes up, removing its stability and forcing the back leg to work even harder. Maintain controlled movement while keeping your knee and ankle aligned. Repeat the exercise on both sides, focusing extra effort on the weaker leg to build balanced strength.

ADHD… As An Adult?
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.
ADHD—not just for kids!
Consider the following:
- If a kid has consistent problems paying attention, it’s easy and common to say “Aha, ADHD!”
- If a young adult has consistent problems paying attention, it’s easy and common to say “Aha, a disinterested ne’er-do-well!”
- If an older adult has consistent problems paying attention, it’s easy and common to say “Aha, a senior moment!”
Yet, if we recognize that ADHD is fundamentally a brain difference in children (and we do; there are physiological characteristics that we can test), and we can recognize that as people get older our brains typically have less neuroplasticity (ability to change) than when we are younger rather than less, then… Surely, there are just as many adults with ADHD as kids!
After all, that rather goes with the linear nature of time and the progressive nature of getting older.
So why do kids get diagnoses so much more often than adults?
Parents—and schools—can find children’s ADHD challenging, and it’s their problem, so they look for an explanation, and ADHD isn’t too difficult to find as a diagnosis.
Meanwhile, adults with ADHD have usually developed coping mechanisms, have learned to mask and/or compensate for their symptoms, and we expect adults to manage their own problems, so nobody’s rushing to find an explanation on their behalf.
Additionally, the stigma of neurodivergence—especially something popularly associated with children—isn’t something that many adults will want for themselves.
But, if you have an ADHD brain, then recognizing that (even if just privately to yourself) can open the door to much better management of your symptoms… and your life.
So what does ADHD look like in adults?
ADHD involves a spread of symptoms, and not everyone will have them all, or have them in the same magnitude. However, very commonly most noticeable traits include:
- Lack of focus (ease of distraction)
- Conversely: high focus (on the wrong things)
- To illustrate: someone with ADHD might set out to quickly tidy the sock drawer, and end up Marie Kondo-ing their entire wardrobe… when they were supposed to doing something else
- Conversely: high focus (on the wrong things)
- Poor time management (especially: tendency to procrastinate)
- Forgetfulness (of various kinds—for example, forgetting information, and forgetting to do things)

Wait, where’s the hyperactivity in this Attention Deficit Hyperactivity Disorder?
It’s often not there. ADHD is simply badly-named. This stems from how a lot of mental health issues are considered by society in terms of how much they affect (and are observable by) other people. Since ADHD was originally noticed in children (in fact being originally called “Hyperkinetic Reaction of Childhood”), it ended up being something like:
“Oh, your brain has an inconvenient relationship with dopamine and you are driven to try to correct that by shifting attention from boring things to stimulating things? You might have trouble-sitting-still disorder”
Hmm, this sounds like me (or my loved one); what to do now at the age of __?
Some things to consider:
- If you don’t want medication (there are pros and cons, beyond the scope of today’s article), you might consider an official diagnosis not worth pursuing. That’s fine if so, because…
- More important than whether or not you meet certain diagnostic criteria, is whether or not the strategies recommended for it might help you.
- Whether or not you talk to other people about it is entirely up to you. Maybe it’s a stigma you’d rather avoid… Or maybe it’ll help those around you to better understand and support you.
- Either way, you might want to learn more about ADHD in adults. Today’s article was about recognizing it—we’ll write more about managing it another time!
In the meantime… We recommended a great book about this a couple of weeks ago; you might want to check it out:

The Circadian Rhythm: Far More Than Most People Know
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 Circadian Rhythm: Far More Than Most People Know
This is Dr. Satchidananda (Satchin) Panda, the scientist behind the discovery of the blue-light sensing cell type in the retina, and the many things it affects. But, he’s discovered more…
First, what you probably know (with a little more science)
Dr. Panda discovered that melanopsin, a photopigment, is “the primary candidate for photoreceptor-mediated entrainment”.
To put that in lay terms, it’s the brain’s go-to for knowing approximately what time of day or night it is, according to how much light there is (or isn’t), and how long it has (or hasn’t) been there.
But… the brain’s “go-to” isn’t the only method. By creating mice without melanopsin, he was able to find that they still keep a circadian rhythm, even in complete darkness:
Melanopsin (Opn4) Requirement for Normal Light-Induced Circadian Phase Shifting
In other words, it was a helpful, but not completely necessary, means of keeping a circadian rhythm.
So… What else is going on?
Dr. Panda and his team did a lot of science that is well beyond the scope of this main feature, but to give you an idea:
- With jargon: it explored the mechanisms and transcription translation negative feedback loops that regulate chronobiological processes, such as a histone lysine demathlyase 1a (JARID1a) that enhances Clock-Bmal1 transcription, and then used assorted genomic techniques to develop a model for how JARID1a works to moderate the level of Per transcription by regulating the transition between its repression and activation, and discovered that this heavily centered on hepatic gluconeogenesis and glucose homeostasis, facilitated by the protein cryptochrome regulating the fasting signal that occurs when glucagon binds to a G-protein coupled receptor, triggering CREB activation.
- Without jargon: a special protein tells our body how to respond to eating/fasting at different times of day—and conversely, certain physiological responses triggered by eating/fasting help us know what time of day it is.
- Simplest: our body keeps on its best cycle if we eat at the same time every day
This is important, because our circadian rhythm matters for a lot more than sleeping/waking! Take hormones, for example:
- Obvious hormones: testosterone and estrogen peak in the mornings around 9am, progesterone peaks between 10pm and 2am
- Forgotten hormones: cortisol peaks in the morning around 8:30am, melatonin peaks between 10pm and 2am
- More hormones: ghrelin (hunger hormone) peaks around 10am, leptin (satiety hormone) peaks 20 minutes after eating a certain amount of satiety-triggering food (protein does this most quickly), insulin is heavily tied to carbohydrate intake, but will still peak and trough according to when the body expects food.
What does this mean for us in practical terms?
For a start, it means that intermittent fasting can help guard against metabolic and related diseases (including inflammation, and thus also cancer, diabetes, arthritis, and more) a lot more if we practice it with our circadian rhythm in mind.
So that “8-hour window” for eating, that many intermittent fasting practitioners adhere to, is going to do much, much better if it’s 10am to 6pm, rather than, say, 4pm to midnight.
Additionally, Dr. Panda and his team found that a 12-hour eating window wasn’t sufficient to help significantly.
Some other take-aways:
- For reasons beyond the scope of this article, it’s good to exercise a) early b) before eating, so getting in some exercise between 8.30am and 10am is ideal
- It also means it’s beneficial to “front-load” eating, so a large breakfast at 10am, and smaller meals/snacks afterwards, is best.
- It also means that getting sunlight (even if cloud-covered) around 8.30am helps guard against metabolic disorders a lot, since the light remains the body’s go-to way of knowing the time.
- We realize that sunlight is not available at 8.30am at all latitudes at all times of year. Artificial is next-best.
- It also means sexual desire will typically peak in men in the mornings (per testosterone) and women in the evenings (per progesterone), but this is just an interesting bit of trivia, and not so relevant to metabolic health
What to do next…
Want to stabilize your own circadian rhythm in the best way, and also help Dr. Panda with his research?
His team’s (free!) app, “My Circadian Clock”, can help you track and organize all of the body’s measurable-by-you circadian events, and, if you give permission, will contribute to what will be the largest-yet human study into the topics covered today, to refine the conclusions and learn more about what works best.

Want to sleep longer? Adding mini-bursts of exercise to your evening routine can help – new study
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.
Exercising before bed has long been discouraged as the body doesn’t have time to wind down before the lights go out.
But new research has found breaking up a quiet, sedentary evening of watching television with short bursts of resistance exercise can lead to longer periods of sleep.
Adults spend almost one third of the 24-hour day sleeping. But the quality and length of sleep can affect long-term health. Sleeping too little or waking often in the night is associated with an increased risk of heart disease and diabetes.
Physical activity during the day can help improve sleep. However, current recommendations discourage intense exercise before going to bed as it can increase a person’s heart rate and core temperature, which can ultimately disrupt sleep.
Nighttime habits
For many, the longest period of uninterrupted sitting happens at home in the evening. People also usually consume their largest meal during this time (or snack throughout the evening).
Insulin (the hormone that helps to remove sugar from the blood stream) tends to be at a lower level in the evening than in the morning.
Together these factors promote elevated blood sugar levels, which over the long term can be bad for a person’s health.
Our previous research found interrupting evening sitting every 30 minutes with three minutes of resistance exercise reduces the amount of sugar in the bloodstream after eating a meal.
But because sleep guidelines currently discourage exercising in the hours before going to sleep, we wanted to know if frequently performing these short bursts of light activity in the evening would affect sleep.
Activity breaks for better sleep
In our latest research, we asked 30 adults to complete two sessions based in a laboratory.
During one session the adults sat continuously for a four-hour period while watching streaming services. During the other session, they interrupted sitting by performing three minutes of body-weight resistance exercises (squats, calf raises and hip extensions) every 30 minutes.
After these sessions, participants went home to their normal life routines. Their sleep that evening was measured using a wrist monitor.
Our research found the quality of sleep (measured by how many times they woke in the night and the length of these awakenings) was the same after the two sessions. But the night after the participants did the exercise “activity breaks” they slept for almost 30 minutes longer.
Identifying the biological reasons for the extended sleep in our study requires further research.
But regardless of the reason, if activity breaks can extend sleep duration, then getting up and moving at regular intervals in the evening is likely to have clear health benefits.
Time to revisit guidelines
These results add to earlier work suggesting current sleep guidelines, which discourage evening exercise before bed, may need to be reviewed.
As the activity breaks were performed in a highly controlled laboratory environment, future research should explore how activity breaks performed in real life affect peoples sleep.
We selected simple, body-weight exercises to use in this study as they don’t require people to interrupt the show they may be watching, and don’t require a large space or equipment.
If people wanted to incorporate activity breaks in their own evening routines, they could probably get the same benefit from other types of exercise. For example, marching on the spot, walking up and down stairs, or even dancing in the living room.
The key is to frequently interrupt evening sitting time, with a little bit of whole-body movement at regular intervals.
In the long run, performing activity breaks may improve health by improving sleep and post-meal blood sugar levels. The most important thing is to get up frequently and move the body, in a way the works best for a person’s individual household.
