Want to sleep longer? Adding mini-bursts of exercise to your evening routine can help – new study

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.

The Path to Longevity – by Dr. Luigi Fontana
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 other “expand your healthspan” books, and while they’re good (or else we wouldn’t include them), this is top-tier, up there with Dr. Greger’s books while being more accessible (more on this later).
This book is far more informational than opinionated, and while some reviewers have described the book as motivating them, that’s not at all the tone, and it’s clear that (beyond hoping for the reader to have to information to promote a long healthy life), the author has no particular agenda to push.
One example: while he gives a whole-foods, plant-based diet a “A+” rating, he puts the (often meat/fish-heavy) paleo diet at a close “A-“, depending on the animal products chosen (which can swing it a lot, and he discusses this in some detail).
In the category of criticism… This reviewer has none. Sometimes it seemed something was going unaddressed, but it would be addressed later.
Stylistically, the text is easy-reading and/but has a lot of references to hard science, complete with charts, diagrams, and so forth. The impression that this reviewer got is that Dr. Fontana took pains to convey as much science as possible, with (unlike Dr. Greger) as little jargon as possible. And that goes a long way.
Bottom line: if you’re looking for a “healthy aging” book that has a lot more science than “copy the Blue Zone supercentenarians and hope” without being so scientifically dense as “How Not To Die” or “How Not To Age“, then this is the book for you.

Elderly loss of energy

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
❝Please please give some information on elderly loss of energy and how it can be corrected. Please!❞
A lot of that is the metabolic slump described above! While we certainly wouldn’t describe 60 as elderly, and the health impacts from those changes at 45–55 get a gentler curve from 60 onwards… that curve is only going in one direction if we don’t take exceptionally good care of ourselves.
And of course, there’s also a degree of genetic lottery, and external factors we can’t entirely control (e.g. injuries etc).
One factor that gets overlooked a lot, though, is really easy to fix: B-vitamins.
In particular, vitamins B1, B5, B6, and B12. Of those, especially vitamins B1 and B12.
(Vitamins B5 and B6 are critical to health too, but relatively few people are deficient in those, while many are deficient in B1 and/or B12, especially as we get older)
Without going so detailed as to make this a main feature: these vitamins are essential for energy conversion from food, and they will make a big big difference.
You might especially want to consider taking sulbutiamine, which is a synthetic version of thiamin (vitamin B1), and instead of being water-soluble, it’s fat-soluble, and it easily crosses the blood-brain barrier, which is a big deal.
As ever, always check with your doctor because your needs/risks may be different. Also, there can be a lot of reasons for fatigue and you wouldn’t want to overlook something important.
You might also want to check out yesterday’s sponsor, as they offer personalized at-home health testing to check exactly this sort of thing.
❝What are natural ways to lose weight after 60? Taking into account bad knees or ankles, walking may be out as an exercise, running certainly is.❞
Losing weight is generally something that comes more from the kitchen than the gym, as most forms of exercise (except HIIT; see below) cause the metabolism to slow afterwards to compensate.
However, exercise is still very important, and swimming is a fine option if that’s available to you.
A word to the wise: people will often say “gentle activities, like tai chi or yoga”, and… These things are not the same.
Tai chi and yoga both focus on stability and suppleness, which are great, but:
- Yoga is based around mostly static self-support, often on the floor
- Tai chi will have you very often putting most of your weight on one slowly-increasingly bent knee at a time, and if you have bad knees, we’ll bet you winced while reading that.
So, maybe skip tai chi, or at least keep it to standing meditations and the like, not dynamic routines. Qigong, the same breathing exercises used in tai chi, is also an excellent way to improve your metabolism, by the way.
Ok, back onto HIIT:

Surgery is the default treatment for ACL injuries in Australia. But it’s not the only way
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 anterior cruciate ligament (ACL) is an important ligament in the knee. It runs from the thigh bone (femur) to the shin bone (tibia) and helps stabilise the knee joint.
Injuries to the ACL, often called a “tear” or a “rupture”, are common in sport. While a ruptured ACL has just sidelined another Matildas star, people who play sport recreationally are also at risk of this injury.
For decades, surgical repair of an ACL injury, called a reconstruction, has been the primary treatment in Australia. In fact, Australia has among the highest rates of ACL surgery in the world. Reports indicate 90% of people who rupture their ACL go under the knife.
Although surgery is common – around one million are performed worldwide each year – and seems to be the default treatment for ACL injuries in Australia, it may not be required for everyone.
PeopleImages.com – Yuri A/Shutterstock What does the research say?
We know ACL ruptures can be treated using reconstructive surgery, but research continues to suggest they can also be treated with rehabilitation alone for many people.
Almost 15 years ago a randomised clinical trial published in the New England Journal of Medicine compared early surgery to rehabilitation with the option of delayed surgery in young active adults with an ACL injury. Over half of people in the rehabilitation group did not end up having surgery. After five years, knee function did not differ between treatment groups.
The findings of this initial trial have been supported by more research since. A review of three trials published in 2022 found delaying surgery and trialling rehabilitation leads to similar outcomes to early surgery.
A 2023 study followed up patients who received rehabilitation without surgery. It showed one in three had evidence of ACL healing on an MRI after two years. There was also evidence of improved knee-related quality of life in those with signs of ACL healing compared to those whose ACL did not show signs of healing.
Experts used to think an ACL tear couldn’t heal without surgery – now there’s evidence it can. SKYKIDKID/Shutterstock Regardless of treatment choice the rehabilitation process following ACL rupture is lengthy. It usually involves a minimum of nine months of progressive rehabilitation performed a few days per week. The length of time for rehabilitation may be slightly shorter in those not undergoing surgery, but more research is needed in this area.
Rehabilitation starts with a physiotherapist overseeing simple exercises right through to resistance exercises and dynamic movements such as jumping, hopping and agility drills.
A person can start rehabilitation with the option of having surgery later if the knee remains unstable. A common sign of instability is the knee giving way when changing direction while running or playing sports.
To rehab and wait, or to go straight under the knife?
There are a number of reasons patients and clinicians may opt for early surgical reconstruction.
For elite athletes, a key consideration is returning to sport as soon as possible. As surgery is a well established method, athletes (such as Matilda Sam Kerr) often opt for early surgical reconstruction as this gives them a more predictable timeline for recovery.
At the same time, there are risks to consider when rushing back to sport after ACL reconstruction. Re-injury of the ACL is very common. For every month return to sport is delayed until nine months after ACL reconstruction, the rate of knee re-injury is reduced by 51%.
For people who opt to try rehabilitation, the option of having surgery later is still there. PeopleImages.com – Yuri A/Shutterstock Historically, another reason for having early surgical reconstruction was to reduce the risk of future knee osteoarthritis, which increases following an ACL injury. But a review showed ACL reconstruction doesn’t reduce the risk of knee osteoarthritis in the long term compared with non-surgical treatment.
That said, there’s a need for more high-quality, long-term studies to give us a better understanding of how knee osteoarthritis risk is influenced by different treatments.
Rehab may not be the only non-surgical option
Last year, a study looking at 80 people fitted with a specialised knee brace for 12 weeks found 90% had evidence of ACL healing on their follow-up MRI.
People with more ACL healing on the three-month MRI reported better outcomes at 12 months, including higher rates of returning to their pre-injury level of sport and better knee function. Although promising, we now need comparative research to evaluate whether this method can achieve similar results to surgery.
What to do if you rupture your ACL
First, it’s important to seek a comprehensive medical assessment from either a sports physiotherapist, sports physician or orthopaedic surgeon. ACL injuries can also have associated injuries to surrounding ligaments and cartilage which may influence treatment decisions.
In terms of treatment, discuss with your clinician the pros and cons of management options and whether surgery is necessary. Often, patients don’t know not having surgery is an option.
Surgery appears to be necessary for some people to achieve a stable knee. But it may not be necessary in every case, so many patients may wish to try rehabilitation in the first instance where appropriate.
As always, prevention is key. Research has shown more than half of ACL injuries can be prevented by incorporating prevention strategies. This involves performing specific exercises to strengthen muscles in the legs, and improve movement control and landing technique.

Health Simplified – by Daniel Cottmeyer
A lot of books focus on the most marketable aspects of health, such as fat loss or muscle gain. Instead, Cottmeyer takes a “birds-eye-view” of health in all its aspects, and then boils it down to the most critical key parts.
Rather than giving a science-dense tome that nobody reads, or a light motivational piece that everyone reads but it amounts to “you can do it!”, here we get substance… but in a digestible form.
Which we at 10almonds love.
The book presents a simple action plan to:
- Improve your relationship with food/exercise
- Actually get better sleep
- Understand how nutrition really works
- Set up helpful habits that are workable and sustainable
- Bring these components together synergistically
Bottom line: if you’re going to buy only one health/fitness book, this is a fine contender.

Seriously Useful Communication Skills!
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.
What Are Communication Skills, Really?
Superficially, communication is “conveying an idea to someone else”. But then again…
Superficially, painting is “covering some kind of surface in paint”, and yet, for some reason, the ceiling you painted at home is not regarded as equally “good painting skills” as Michaelangelo’s, with regard to the ceiling of the Sistine Chapel.
All kinds of “Dark Psychology” enthusiasts on YouTube, authors of “Office Machiavelli” handbooks, etc, tell us that good communication skills are really a matter of persuasive speaking (or writing). And let’s not even get started on “pick-up artist” guides. Bleugh.
Not to get too philosophical, but here at 10almonds, we think that having good communication skills means being able to communicate ideas simply and clearly, and in a way that will benefit as many people as possible.
The implications of this for education are obvious, but what of other situations?
Conflict Resolution
Whether at work or at home or amongst friends or out in public, conflict will happen at some point. Even the most well-intentioned and conscientious partners, family, friends, colleagues, will eventually tread on our toes—or we, on theirs. Often because of misunderstandings, so much precious time will be lost needlessly. It’s good for neither schedule nor soul.
So, how to fix those situations?
I’m OK; You’re OK
In the category of “bestselling books that should have been an article at most”, a top-tier candidate is Thomas Harris’s “I’m OK; You’re OK”.
The (very good) premise of this (rather padded) book is that when seeking to resolve a conflict or potential conflict, we should look for a win-win:
- I’m not OK; you’re not OK ❌
- For example: “Yes, I screwed up and did this bad thing, but you too do bad things all the time”
- I’m OK; you’re not OK ❌
- For example: “It is not I who screwed up; this is actually all your fault”
- I’m not OK; you’re OK ❌
- For example: “I screwed up and am utterly beyond redemption; you should immediately divorce/disown/dismiss/defenestrate me”
- I’m OK; you’re OK ✅
- For example: “I did do this thing which turned out to be incorrect; in my defence it was because you said xyz, but I can understand why you said that, because…” and generally finding a win-win outcome.
So far, so simple.
“I”-Messages
In a conflict, it’s easy to get caught up in “you did this, you did that”, often rushing to assumptions about intent or meaning. And, the closer we are to the person in question, the more emotionally charged, and the more likely we are to do this as a knee-jerk response.
“How could you treat me this way?!” if we are talking to our spouse in a heated moment, perhaps, or “How can you treat a customer this way?!” if it’s a worker at Home Depot.
But the reality is that almost certainly neither our spouse nor the worker wanted to upset us.
Going on the attack will merely put them on the defensive, and they may even launch their own counterattack. It’s not good for anyone.
Instead, what really happened? Express it starting with the word “I”, rather than immediately putting it on the other person. Often our emotions require a little interrogation before they’ll tell us the truth, but it may be something like:
“I expected x, so when you did/said y instead, I was confused and hurt/frustrated/angry/etc”
Bonus: if your partner also understands this kind of communication situation, so much the better! Dark psychology be damned, everything is best when everyone knows the playbook and everyone is seeking the best outcome for all sides.
The Most Powerful “I”-Message Of All
Statements that start with “I” will, unless you are rules-lawyering in bad faith, tend to be less aggressive and thus prompt less defensiveness. An important tool for the toolbox, is:
“I need…”
Softly spoken, firmly if necessary, but gentle. If you do not express your needs, how can you expect anyone to fulfil them? Be that person a partner or a retail worker or anyone else. Probably they want to end the conflict too, so throw them a life-ring and they will (if they can, and are at least halfway sensible) grab it.
- “I need an apology”
- “I need a moment to cool down”
- “I need a refund”
- “I need some reassurance about…” (and detail)
Help the other person to help you!
Everything’s best when it’s you (plural) vs the problem, rather than you (plural) vs each other.
Apology Checklist
Does anyone else remember being forced to write an insincere letter of apology as a child, and the literary disaster that probably followed? As adults, we (hopefully) apologize when and if we mean it, and we want our apology to convey that.
What follows will seem very formal, but honestly, we recommend it in personal life as much as professional. It’s a ten-step apology, and you will forget these steps, so we recommend to copy and paste them into a Notes app or something, because this is of immeasurable value.
It’s good not just for when you want to apologize, but also, for when it’s you who needs an apology and needs to feel it’s sincere. Give your partner (if applicable) a copy of the checklist too!
- Statement of apology—say “I’m sorry”
- Name the offense—say what you did wrong
- Take responsibility for the offense—understand your part in the problem
- Attempt to explain the offense (not to excuse it)—how did it happen and why
- Convey emotions; show remorse
- Address the emotions/damage to the other person—show that you understand or even ask them how it affected them
- Admit fault—understand that you got it wrong and like other human beings you make mistakes
- Promise to be better—let them realize you’re trying to change
- Tell them how you will try to do it different next time and finally
- Request acceptance of the apology
Note: just because you request acceptance of the apology doesn’t mean they must give it. Maybe they won’t, or maybe they need time first. If they’re playing from this same playbook, they might say “I need some time to process this first” or such.

Strawberries vs Cherries – 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 cherries, we picked the cherries.
Why?
It was close, and certainly both are great!
When it comes to vitamins and minerals, each fruit has its strengths (and both are excellent sources of vitamins and minerals), but on balance, strawberry comes out a little higher—especially for vitamin C, as a cup of strawberries can provide the daily recommended amount already.
In terms of macros, strawberries have less sugar, but this isn’t really a big deal when it comes to fruit, as the fiber content and polyphenols more than offset any negative effects.
Speaking of which, the fiber content is comparable for each fruit, and both contain a lot of antioxidants.
What swings it into cherries’ favor is cherries’ slew of specific phytochemical benefits, including cherry-specific anti-inflammatory properties, sleep-improving abilities, and post-exercise recovery boosts, as well as anti-diabetic benefits above and beyond the normal “this is a fruit” level.
In short, both are very respectable fruits, but cherries have some qualities that are just special, and that we feel outweigh the “has more vitamin C” of strawberries.
We’ll do a main feature on cherries’ medicinal properties sometime soon, but in the meantime, if you’d like to try a tart cherry supplement, here’s an example product on Amazon
