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.

Life Is in the Transitions – by Bruce Feiler

Change happens. Sometimes, because we choose it. More often, we don’t get a choice.
Our bodies change; with time, with illness, with accident or incident, or even, sometimes, with effort. People in our lives change; they come, they go, they get sick, they die. Our working lives change; we get a job, we lose a job, we change jobs, our jobs change, we retire.
Whether we’re undergoing cancer treatment or a religious conversion, whether our families are growing or down to the last few standing, change is inescapable.
Our author makes the case that on average, we each undergo at least 5 major “lifequakes”; changes that shake our lives to the core. Sometimes one will come along when we’ve barely got back on our feet from the previous—if we have at all.
What, then, to do about this? We can’t stop change from occurring, and some changes aren’t easy to “roll with”. Feiler isn’t prescriptive about this, but rather, descriptive:
By looking at the stories of hundreds of people he interviewed for this book, he looks at how people pivoted on the spot (or picked up the pieces!) and made the best of their situation—or didn’t.
Bottom line: zooming out like this, looking at many people’s lives, can remind us that while we don’t get to choose what winds we get swept by, we at least get to choose how we set the sails. The examples of others, as this book gives, can help us make better decisions.

From Tofu to Salmon
This video (below) by SweetPotatoSoul isn’t just a recipe tutorial; it’s an inspiring journey into the world of vegan cooking, proving that reducing animal products doesn’t have to mean sacrificing flavor.
The key to her vegan salmon is the tofu. However, there’s a trick to the tofu – you have to press it.
Essentially, this involved putting some paper towel on either side of the tofu, and then placing a heavy object on top; this removes excess water and, more importantly, primes the tofu to absorb the flavor of your marinade!
(You’ll want to press the tofu for around 1 hour)
Find the rest of the recipe in the 12-minute video below!
Other Plant-Based Recipes
With there being so many benefits of cutting meat out of your diet, we’ve spent the time reviewing some of the top books on vegan recipes, including The Green Roasting Tin and The Vegan Instant Pot Cookbook. We hope you enjoy them as much as you’ll enjoy this recipe:

Is thunderstorm asthma becoming more common?
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.
When spring arrives, so do warnings about thunderstorm asthma. But a decade ago, most of us hadn’t heard of it.
So where did thunderstorm asthma come from? Is it a new phenomenon?
In 2016, the world’s most catastrophic thunderstorm asthma event took Melbourne by surprise. An increase in warnings and monitoring is partly a response to this.
But there are also signs climate change may be exacerbating the likelihood of thunderstorm asthma, with more extreme weather, extended pollen seasons and a rise in Australians reporting hay fever.
A landmark catastrophe
The first time many Australians heard of thunderstorm asthma was in November 2016, when a major event rocked Melbourne.
During a late night storm, an estimated 10,000 people were rushed to hospitals with severe asthma attacks. With thousands of calls on emergency lines, ambulances and emergency departments were unprepared to handle the rapid increase in people needing urgent medical care. Tragically, ten of those people died.
This was the most catastrophic thunderstorm asthma event in recorded history and the first time deaths have ever occurred anywhere in the world.
In response, the Victorian Department of Health implemented initiatives, including public awareness campaigns and improvements to health and emergency services, to be ready for future thunderstorm asthma events.
A network of pollen monitoring stations was also set up across the state to gather data that helps to predict future events.
A problem for decades
While this event was unexpected, it wasn’t the first time we’d had thunderstorm asthma in Australia – we’ve actually known about it for decades.
Melbourne reported its first instance of thunderstorm asthma back in 1984, only a year after this phenomenon was first discovered in Birmingham in the United Kingdom.
Thunderstorm asthma has since been reported in other parts of Australia, including Canberra and New South Wales. But it is still most common in Melbourne. Compared to any other city (or country) the gap is significant: over a quarter of all known events worldwide have occurred in Melbourne.
Why Melbourne?
Melbourne’s location makes it a hotspot for these kinds of events. Winds coming from the north of Melbourne tend to be dry and hot as they come from deserts in the centre of Australia, while winds from the south are cooler as they come from the ocean.
When hot and cool air mix above Melbourne, it creates the perfect conditions for thunderstorms to form.
Northern winds also blow a lot of pollen from farmlands into the city, in particular grass pollen. This is not only the most common cause of seasonal hay fever in Melbourne but also a major trigger of thunderstorm asthma.
Why grass pollen?
There’s a particular reason grass pollen is the main culprit behind thunderstorm asthma in Australia. During storms there is a lot of moisture in the air. Grass pollen will absorb this moisture, making it swell up like a water balloon.
If pollen absorbs too much water whilst airborne, it can burst or “rupture,” releasing hundreds of microscopic particles into the air that can be swept by powerful winds.
Normally, when you breathe in pollen it gets stuck in your upper airway – for example, your nose and throat. This is what causes typical hay fever symptoms such as sneezing or runny nose.
But the microscopic particles released from ruptured grass pollen are much smaller and don’t get stuck as easily in the upper airway. Instead, they can travel deep into your airways until they reach your lungs. This may trigger more severe symptoms, such as wheezing or difficulty breathing, even in people with no prior history of asthma.
So who is at risk?
You might think asthma is the biggest risk factor for thunderstorm asthma. In fact, the biggest risk factor is hay fever.
Up to 99% of patients who went to the emergency department during the Melbourne 2016 event had hay fever, while a majority (60%) had no prior diagnosis of asthma.
Every single person hospitalised was allergic to at least one type of grass pollen. All had a sensitivity to ryegrass.
Is thunderstorm asthma becoming more common?
Thunderstorm asthma events are rare, with just 26 events officially recorded worldwide.
However there is evidence these events could become more frequent and severe in coming years, due to climate change. Higher temperatures and pollution could be making plants produce more pollen and pollen seasons last much longer.
Extreme weather events, including thunderstorms, are also expected to become more common and severe.
In addition, there are signs rates that hay fever may be increasing. The number of Australians reporting allergy symptoms have risen from 15% in 2008 to 24% in 2022. Similar trends in other countries has been linked to climate change.
How can I prepare?
Here are three ways you can reduce your risk of thunderstorm asthma:
- stock up on allergy medication and set up an asthma action plan with your GP
- check daily pollen forecasts for the estimated pollen level and risk of a thunderstorm asthma event in your local area
- on days with high pollen or a high risk of thunderstorm asthma, spend less time outside or wear a surgical face mask to reduce your symptoms.

What’s Your Personal Life Expectancy?
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.
Tick Tock… Goes the Death Clock?
This fun little test will ask a few questions about you and your lifestyle, and then make a prediction of your personal life expectancy, based on global statistics from the World Health Organisation.
And then the countdown starts… Literally, it generates a clock for you to see your life-seconds ticking away—this may or may not delight you, but it sure is a curiosity.
Their “Letters” page has a lot of reactions from people who just got their results (spoiler: people’s perspectives on life vary a lot)
Who mostly uses this service? According to their stats page, it’s mostly curious under-45s, with gradually less interest in knowing about it from 45 onwards… until the age of 70, when suddenly everyone wants to know about it again!
So Is It Possible To Pause The Clock On Aging? – Q&A Spotlight Interview
Life extension is sometimes viewed as the domain of the super-rich, and with less than half of Millennials (and almost none of Gen-Z) having retirement plans, often those of us who aren’t super-rich have more mundane (and immediate!) goals than living to 120.
And yet…
Middle class and working class life-extensionists do exist, even if not garnering the same media attention. We think that’s strange—after all, while the whimsies of the super-rich may be entertaining to read about, it’s not nearly as applicable to most people as more relatable stories:
- The twenty-something who gives up smoking and adds (healthier!) years to their life
- The thirty-something who adopts a plant-based diet and is less likely to die of heart disease
- The forty-something who stops drinking, and avoids health conditions and mishaps alike
- The fifty-something who reconsiders their health plan in light of their changing body
- The sixty-something who takes up yoga, or chess, or salsa dancing
- The seventy-something who gets asked what their secret is
- …and so on
But these are ideas, textbook examples. What if we make it more personal?
We interviewed 10 Almonds subscriber and longevity enthusiast Anastasia S., and here’s what she had to say:
Q: What does life extension mean to you, in your life?
A: To me, the key is healthy life extension. People often joke “I don’t want to live longer; the last years are the worst!” but they’re missing the point that after a certain age, those difficulties are coming whether they come at 50 or 70 or 90. Personally, I’d rather keep them at bay if I can.
Q: How do you do that?
A: Firstly, which won’t be a shock: good diet and exercise. Those two things are possibly the biggest active influences on my longevity. I’m vegan, which I don’t think is outright necessary for good health but done right, it can certainly be good. In this house we eat a lot of whole grains, beans, lentils, vegetables in general, nuts too. As for exercise, I do 30–60 minutes of Pilates daily; it’s nothing fancy and it’s just me in my pajamas at home, but it keeps me strong and fit and supple. I also walk everywhere; I don’t even own a car. Beyond that… I don’t drink or smoke (probably the biggest passive influences on my longevity, i.e., things that aren’t there to make it shorter), and I try to take my sleep seriously, making sure to schedule enough time and prepare properly for it.
Q: Take your sleep seriously? How so?
A: Good “sleep hygiene” as some call it—I schedule a little wind-down time before sleep, with no glaring screens or main lights, making a space between my busy day and restful sleep, kicking anything requiring brainpower to the morning, and making a conscious choice not to think more about those things in the meantime. I take care to make my sleeping environment as conducive as possible to good sleep too; I have a good mattress and pillows, I make sure the temperature is cool but cosy. I have a pot of herbal tea on my bedside table—I hydrate a lot.
Q: Do you take any supplements?
A: I do! They’re mostly quite general though, just “covering my bases”, so to speak. I take a daily nootropic stack (a collection of supplements specifically for brain health), too. I buy them in bulk, so they don’t cost so much.
Q: This seems quite a healthy lifestyle! Do you have any vices at all?
A: I definitely drink more coffee than I probably should! But hey, nobody’s perfect. I do love coffee, though, and as vices go, it’s probably not too bad.
Q: How’s it all working out for you? Do you feel younger?
A: I’m 38 and sometimes I feel like a teenager; sometimes I feel like an old lady. But the latter is usually for social reasons, not health-related reasons. I do have streaks of gray in my hair though, and I love that! If people don’t notice my grays, then they often think I’m in my 20s, rather than pushing 40. A little while back, I was stopped in the street by someone wanting to sell me a change of household utilities provider, then she stopped herself mid-sentence and said “Oh but wait, you look a bit too young, never mind”. Most general metrics of health would put me in my 20s.
Q: That’s interesting that you love your gray hairs, for someone who wants to stay young; is it an exception?
A: It’s more that I want to minimize the problems that come with age, and not everything’s a problem. Gray hairs are cool; joint pain, not so much. A long life rich with experiences is cool; memory loss, not so much. So, I try to keep healthy, and wear my years as best I can.
Q: Sounds good to us; good luck with it!
A: Thank you; I do my best!

Statistical Models vs. Front-Line Workers: Who Knows Best How to Spend Opioid Settlement Cash?
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.
MOBILE, Ala. — In this Gulf Coast city, addiction medicine doctor Stephen Loyd announced at a January event what he called “a game-changer” for state and local governments spending billions of dollars in opioid settlement funds.
The money, which comes from companies accused of aggressively marketing and distributing prescription painkillers, is meant to tackle the addiction crisis.
But “how do you know that the money you’re spending is going to get you the result that you need?” asked Loyd, who was once hooked on prescription opioids himself and has become a nationally known figure since Michael Keaton played a character partially based on him in the Hulu series “Dopesick.”
Loyd provided an answer: Use statistical modeling and artificial intelligence to simulate the opioid crisis, predict which programs will save the most lives, and help local officials decide the best use of settlement dollars.
Loyd serves as the unpaid co-chair of the Helios Alliance, a group that hosted the event and is seeking $1.5 million to create such a simulation for Alabama.
The state is set to receive more than $500 million from opioid settlements over nearly two decades. It announced $8.5 million in grants to various community groups in early February.
Loyd’s audience that gray January morning included big players in Mobile, many of whom have known one another since their school days: the speaker pro tempore of Alabama’s legislature, representatives from the city and the local sheriff’s office, leaders from the nearby Poarch Band of Creek Indians, and dozens of addiction treatment providers and advocates for preventing youth addiction.
Many of them were excited by the proposal, saying this type of data and statistics-driven approach could reduce personal and political biases and ensure settlement dollars are directed efficiently over the next decade.
But some advocates and treatment providers say they don’t need a simulation to tell them where the needs are. They see it daily, when they try — and often fail — to get people medications, housing, and other basic services. They worry allocating $1.5 million for Helios prioritizes Big Tech promises for future success while shortchanging the urgent needs of people on the front lines today.
“Data does not save lives. Numbers on a computer do not save lives,” said Lisa Teggart, who is in recovery and runs two sober living homes in Mobile. “I’m a person in the trenches,” she said after attending the Helios event. “We don’t have a clean-needle program. We don’t have enough treatment. … And it’s like, when is the money going to get to them?”
The debate over whether to invest in technology or boots on the ground is likely to reverberate widely, as the Helios Alliance is in discussions to build similar models for other states, including West Virginia and Tennessee, where Loyd lives and leads the Opioid Abatement Council.
New Predictive Promise?
The Helios Alliance comprises nine nonprofit and for-profit organizations, with missions ranging from addiction treatment and mathematical modeling to artificial intelligence and marketing. As of mid-February, the alliance had received $750,000 to build its model for Alabama.
The largest chunk — $500,000 — came from the Poarch Band of Creek Indians, whose tribal council voted unanimously to spend most of its opioid settlement dollars to date on the Helios initiative. A state agency chipped in an additional $250,000. Ten Alabama cities and some private foundations are considering investing as well.
Stephen McNair, director of external affairs for Mobile, said the city has an obligation to use its settlement funds “in a way that is going to do the most good.” He hopes Helios will indicate how to do that, “instead of simply guessing.”
Rayford Etherton, a former attorney and consultant from Mobile who created the Helios Alliance, said he is confident his team can “predict the likely success or failure of programs before a dollar is spent.”
The Helios website features a similarly bold tagline: “Going Beyond Results to Predict Them.”
To do this, the alliance uses system dynamics, a mathematical modeling technique developed at the Massachusetts Institute of Technology in the 1950s. The Helios model takes in local and national data about addiction services and the drug supply. Then it simulates the effects different policies or spending decisions can have on overdose deaths and addiction rates. New data can be added regularly and new simulations run anytime. The alliance uses that information to produce reports and recommendations.
Etherton said it can help officials compare the impact of various approaches and identify unintended consequences. For example, would it save more lives to invest in housing or treatment? Will increasing police seizures of fentanyl decrease the number of people using it or will people switch to different substances?
And yet, Etherton cautioned, the model is “not a crystal ball.” Data is often incomplete, and the real world can throw curveballs.
Another limitation is that while Helios can suggest general strategies that might be most fruitful, it typically can’t predict, for instance, which of two rehab centers will be more effective. That decision would ultimately come down to individuals in charge of awarding contracts.
Mathematical Models vs. On-the-Ground Experts
To some people, what Helios is proposing sounds similar to a cheaper approach that 39 states — including Alabama — already have in place: opioid settlement councils that provide insights on how to best use the money. These are groups of people with expertise ranging from addiction medicine and law enforcement to social services and personal experience using drugs.
Even in places without formal councils, treatment providers and recovery advocates say they can perform a similar function. Half a dozen advocates in Mobile told KFF Health News the city’s top need is low-cost housing for people who want to stop using drugs.
“I wonder how much the results” from the Helios model “are going to look like what people on the ground doing this work have been saying for years,” said Chance Shaw, director of prevention for AIDS Alabama South and a person in recovery from opioid use disorder.
But Loyd, the co-chair of the Helios board, sees the simulation platform as augmenting the work of opioid settlement councils, like the one he leads in Tennessee.
Members of his council have been trying to decide how much money to invest in prevention efforts versus treatment, “but we just kind of look at it, and we guessed,” he said — the way it’s been done for decades. “I want to know specifically where to put the money and what I can expect from outcomes.”
Jagpreet Chhatwal, an expert in mathematical modeling who directs the Institute for Technology Assessment at Massachusetts General Hospital, said models can reduce the risk of individual biases and blind spots shaping decisions.
If the inputs and assumptions used to build the model are transparent, there’s an opportunity to instill greater trust in the distribution of this money, said Chhatwal, who is not affiliated with Helios. Yet if the model is proprietary — as Helios’ marketing materials suggest its product will be — that could erode public trust, he said.
Etherton, of the Helios Alliance, told KFF Health News, “Everything we do will be available publicly for anyone who wants to look at it.”
Urgent Needs vs. Long-Term Goals
Helios’ pitch sounds simple: a small upfront cost to ensure sound future decision-making. “Spend 5% so you get the biggest impact with the other 95%,” Etherton said.
To some people working in treatment and recovery, however, the upfront cost represents not just dollars, but opportunities lost for immediate help, be it someone who couldn’t find an open bed or get a ride to the pharmacy.
“The urgency of being able to address those individual needs is vital,” said Pamela Sagness, executive director of the North Dakota Behavioral Health Division.
Her department recently awarded $7 million in opioid settlement funds to programs that provide mental health and addiction treatment, housing, and syringe service programs because that’s what residents have been demanding, she said. An additional $52 million in grant requests — including an application from the Helios Alliance — went unfunded.
Back in Mobile, advocates say they see the need for investment in direct services daily. More than 1,000 people visit the office of the nonprofit People Engaged in Recovery each month for recovery meetings, social events, and help connecting to social services. Yet the facility can’t afford to stock naloxone, a medication that can rapidly reverse overdoses.
At the two recovery homes that Mobile resident Teggart runs, people can live in a drug-free space at a low cost. She manages 18 beds but said there’s enough demand to fill 100.
Hannah Seale felt lucky to land one of those spots after leaving Mobile County jail last November.
“All I had with me was one bag of clothes and some laundry detergent and one pair of shoes,” Seale said.
Since arriving, she’s gotten her driver’s license, applied for food stamps, and attended intensive treatment. In late January, she was working two jobs and reconnecting with her 4- and 7-year-old daughters.
After 17 years of drug use, the recovery home “is the one that’s worked for me,” she said.

Sun-dried Tomatoes vs Black Olives – 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 sun-dried tomatoes to black olives, we picked the sun-dried tomatoes.
Why?
These common snack-salad items may seem similar in consistency, but their macros are very different: the tomatoes, being dried, have proportionally a lot more protein, carbs, and fiber. The olives, meanwhile, have more fat (and/but yes, a very healthy blend of fats). Note that these comments are true for the things themselves; be aware that sun-dried tomatoes are often sold in vegetable oil, which would obviously change the macros considerably and be much less healthy. So, for the sake of statistics, we’re assuming you got sun-dried tomatoes that aren’t soaked in oil. All in all, we’re calling this category a win for the tomatoes, but those fats from the olives are very good too.
In terms of vitamins, the sun-dried tomatoes being dried again means that the loss of water weight means the vitamin content is proportionally much higher; the tomatoes are higher in vitamins A, B1, B2, B3, B5, B6, B9, C, and K, while olives are higher only in vitamin E (but in their defence, olives have 165x more vitamin E than sun-dried tomatoes). Still, a win for sun-dried tomatoes here.
When it comes to minerals, it’s a similar story for the same reason; the loss of water weight in the sun-dried tomatoes makes them much more nutritionally dense; they are higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while the olives are higher only in sodium. Note, we’re looking at black olives today; green olives would be even higher in sodium than black ones, as they are “cured” for longer.
Lastly, in terms of polyphenols, they both have a lot of great things to bring, but sun-dried tomatoes are pretty much the richest natural source of lycopene, which itself a very powerful polyphenol even my general polyphenol standards, so we’d call this one a win for the sun-dried tomatoes too.
