Increase your sleep time by nearly two hours with this gentle exercise, finds new study
Gentle exercise including yoga, Tai Chi and jogging should be considered a primary treatment method for insomnia, a new review published in the online journal BMJ Evidence Based Medicine suggests.
Roughly one third of the population is expected to experience insomnia at some point but many treatment methods remain inaccessible — such as CBT-I — or come with potential side effects — such as medication.
This review aims to better establish exercise as an accessible treatment for insomnia while encouraging further clinical research into which forms of exercise show the most benefits, to create better guidelines for patients.
Key takeaways of the review
Exercise is a low cost and accessible treatment for insomnia
Yoga, Tai Chi and jogging effectively reduce insomnia severity
Yoga can potentially increase sleep duration by up to two hours
The systematic review undertaken by sleep scientists in China assessed 22 insomnia-focused randomized control trials featuring a total of 1,348 participants and exploring a total of 13 interventions (seven exercise-based.)
What is CBT-I?
CBT-I (Cognitive Behavioral Therapy for Insomnia) is a popular insomnia treatment that aims to reframe your approach and attitude to sleep, to improve your rest. While effective, the low number of practitioners means it's often hard to access.
Based on sleep diary data collected from these studies, yoga, Tai Chi and gentle walking or jogging were determined to have the largest positive impact on insomnia.
Yoga in particular proved effective at increasing sleep duration, adding an average of 110 minutes to the time spent snoozing — that's close to two hours.
Tai Chi also demonstrated benefits across the PSQI (Pittsburgh Sleep Quality Index, a self-reported sleep assessment), as well as improving total sleep time and the time it takes to fall asleep.
In addition, Tai Chi demonstrated long-term benefits for those who had experienced sleep difficulties, continuing to show improvement across sleep outcomes in the one to two year follow-up.
Gentle walking or jogging was also shown to reduce insomnia severity.
While the review recognizes CBT-I as the gold-standard for insomnia treatment, it encourages the above forms of exercise as "viable primary treatment options" for those experiencing insomnia. They recognize the treatments as "well-suited for integration into primary care and community health programmes."
"Body awareness, controlled breathing and attentional training"
The review theorizes that yoga and Tai Chi are particularly effective treatments for insomnia due to their focus on "body awareness, controlled breathing and attention training."
Mindfulness for sleep encourages positive, relaxed thinking, qualities that are also prominent in many forms of yoga and Tai Chi.
The study further theorizes that the "meditative movement" of Tai Chi can encourage emotional regulation while helping quiet busy thoughts. These two features might prove particularly useful for those finding anxiety or stress is keeping them awake.
As for jogging and walking, the researchers behind the review suggest a combination of energy use, increased melatonin production and improved emotion regulation make these exercises particularly sleep-inducing.
The dos and don'ts of exercising for better sleep
Establishing a consistent exercise routine can benefit your sleep and help you avoid insomnia. Here are some dos and don'ts of exercising for better sleep to get you started.
DON'T do strenuous exercise too close to bedtime
We know a packed calendar can make scheduling your workouts a workout in itself, but it's important to consider both when you're exercising and the type of activity you're engaging in to find the best time to exercise for sleep.
Vigorous exercise before bed is likely to keep you awake, as your body struggles to switch off after being put to work. However, research suggests intense workouts in the morning or afternoon can help you achieve deeper sleep.
DO add gentle exercise into your pre-bed routine
Light exercise — such as yoga, Tai Chi and walking — can be beneficial later in the day, particularly if you're using that mind-body connection to calm anxious thoughts that might otherwise plague your sleep.
A few minutes of stretching roughly an hour before bed can help reduce muscle tension and release stress, so you're more relaxed when you climb beneath the covers.
DO exercise for at least an hour a week
Consistency is equally as important as timing when it comes to exercising for better rest — an occasional stretch every few weeks is unlikely to provide any long-term sleep benefits.
Research published in the BMJ Open suggests consistent activity of at least an hour per week can lower your risk of experiencing insomnia symptoms.
DON'T neglect the rest of your sleep routine
Avoid following your half hour of Tai Chi by collapsing on your bed in your gym clothes and scrolling through social media for an hour while eating sugary snacks and enjoying a post-workout beer.
You should also avoid workout supplements if exercising before bed. While it's probably no surprise these energy-inducing drinks contain caffeine, you might be unaware of just how much of the stimulant you'll be consuming — a single supplement can contain the equivalent caffeine of three cups of coffee.
The science behind exercise and sleep is still developing — although this review emphasizes the importance of further research — so above all else, listen to your body.
And if you're experiencing long-term sleep deprivation or insomnia, we recommend speaking to a healthcare professional to develop a treatment plan.

Insomnia is a global epidemic. How do we fix it?
On a special episode (first released on July 24th) of The Excerpt podcast: The question is: Why do we struggle to sleep? Jennifer Senior, a staff writer at The Atlantic, joins The Excerpt to talk about insomnia and what we can do about solving our sleep issues. Hit play on the player below to hear the podcast and follow along with the transcript beneath it. This transcript was automatically generated, and then edited for clarity in its current form. There may be some differences between the audio and the text. Podcasts: True crime, in-depth interviews and more USA TODAY podcasts right here Taylor Wilson: Hello, I'm Taylor Wilson, and this is a special episode of the Excerpt. According to a report released by the American Medical Association earlier this year, one-third of American adults experience acute insomnia, an inability to fall or stay asleep for several days at a time, but one in 10 adults suffer from chronic insomnia. That's an inability to fall or stay asleep three nights a week for three months or more. The condition has potentially debilitating health impacts, including an increased risk of depression, anxiety, substance abuse, and even car accidents. So the question is, why can't we sleep? Here to help me dig into the issue is Jennifer Senior, a staff writer at The Atlantic who recently went on her own journey to solve her insomnia and who shared her story in the magazine. Thank you for joining me, Jennifer. Jennifer Senior: Thanks for having me. Taylor Wilson: So let's start with I guess a 30,000-foot view of the issue. I know you spoke with a lot of sleep specialists, did a lot of independent research for your piece. Jennifer, what's the big picture here on American's trouble with sleep? Jennifer Senior: Right. Yeah. What's funny, I think the story was a little misnamed. I mean, this is really more story about, well, if you can't sleep, don't feel awful about it because there are so many shaming stories about people, whatever solutions people seek out. I do talk in the beginning about the way that the modern world absolutely conspires against sleep, that it just lays waste to your circadian rhythms. That people work two jobs, 16.4% of us work non-standard hours. If you're a white collar kind of professional, you've got these woodpecker like peck, peck, peck, incursions into your life all night and weekend long from your boss's work sort of never ends. I mean, we're just no longer yoked to the rhythms of the earth anymore. We're just part of this whirl of a wired world. Taylor Wilson: In the course of doing your research, was there something in particular that surprised you most about the problem? Jennifer Senior: I'll tell you what surprised me most, just generally. Whenever I interviewed any expert about this, and it didn't matter what species of expert, they could be an epidemiologist, they could be a neurologist, they could be a psychiatrist, they could be a clinician. Most of them said the same thing. There is a slight misconception that you need eight hours of sleep. There is some data saying this. There is another equally robust data set saying 6.5 to 7.4 is associated with the best health outcomes. Now it's very hard to tell. These studies are observational. They're not randomized. There was all sorts of confounds and problems with this, but this one study in particular had a million people in it. It's been replicated. There are plenty of people who believe this data and people vary. And over the course of a lifetime, your individual sleep capacity could change. In a funny way, that was what surprised me most. Right? This mantra, which is kind of a tyranny, get eight hours or else. Taylor Wilson: Well, you talked Jennifer about the modern world conspiring against us and our sleep, and I guess let's try to outline a few of the possible causes of what you call a public health emergency, right? What can you share with us here on this? Jennifer Senior: About other causes, you mean besides the kind of modernity itself and kids working on... Kids being assigned homework online, kids socializing online. I mean, adolescents are desperate for sleep. They're so hungry for it, and modern high schools and middle schools have them waking up preposterously early when their circadian rhythms are pitched forward. We've got a substantial sandwich generation that's taking care of young kids and their elderly parents. That's going to conspire against it. These are all immutable things. Also, there are elevated levels of anxiety now in our world, and anxiety itself is a huge source of... Or can be a source of sleeplessness, certainly can make one prone. So I mean, those are additional examples I suppose. Taylor Wilson: Let's talk through your story a bit here. When did you first realize that you had an issue with sleep? And walk us through your experience with insomnia. Jennifer Senior: It was 25 years ago and it was a very mysterious onset. I cannot tell you what brought it on to this day. It is a mystery. I had this extremely well-regulated kind of circadian clock. I fell asleep every night at 1:00. I woke up every day at 9:00. I lost my alarm clock. I still woke up at those times. I didn't have to buy a new alarm clock until I had an early flight one day, and yet sometime very close to my 29th birthday when virtually no circumstances in my life had changed one iota, I had a bad night, fell asleep at like 5:00. Thought nothing of it until they became more regular, and then I started doing all-nighters involuntarily, and I felt like I'd been poisoned. And to this day, I don't know what happened, but once that happens, the whole cycle starts to happen, then people suddenly become very afraid of not falling asleep and whatever kicked it off whether it's mysterious or known becomes irrelevant because then what you do is you start getting very agitated and going, oh my God, I'm not sleeping. Oh my God, I'm still not sleeping. Now it's 3:00 in the morning. Now it's 4:00 in the morning. Now it's 5:00 in the morning. Oh my God, I have one more hour, et cetera. Taylor Wilson: Well, you did write in the piece about the many different recommendations that she tried to solve your own sleep issues. What were some of them, Jennifer, and did any of them help? Jennifer Senior: Oh God, I tried all the things. This is before I sought real professional help, but I did all the things. I would took Tylenol PM, which did not work. I did acupuncture, which were lovely, but did not work. I listened to a meditation tape that a friend gave me, did not work. I listened to another one that was for sleep only that did not work. I ran. I always was a runner, but I ran extra, did not work. Gosh, changed my diet. I don't remember. I did all sorts of things. I tried different supplements, Valerian root, all these things. Melatonin, nothing, nothing. Taylor Wilson: You wrote in depth about one therapy that was recommended to you, and that was CBTI. That's cognitive based therapy for insomnia. Jennifer, first, what is this? And second, did you find any success by using this? Jennifer Senior: So cognitive behavioral therapy for insomnia, as you said, is the gold standard for treating insomnia. It's portable. You can take it with you. It's not like if you leave your sleep meds at home. The main tent pole of it, which is sleep restriction, which I'll get to in a minute, is very hard to do. I found it murder, the kind of easier parts, although they're still in a funny way, kind of paradoxical, are you have to change your thinking around this is the cognitive piece around sleeping and insomnia. You have to decide, okay, I'm not sleeping. So what? Now, this is kind of funny because there's this din surrounding us that says, oh my God, you're not sleeping. You're going to die of a heart attack. You're going to die of an immune disease. You're going to get cancer. All these things, right? You have to set that all aside and decide one more night's sleep that I can't sleep. So what? Right. That's one thing. You have to change your behaviors, deciding that you are going to consistently go to bed at the same time, wake up at the same time, all that, and not use your bed for anything other than just for sleeping and sex. The hard part and the most powerful part that I found it brutal was the part that said you have to restrict your sleep. If you had only five hours of sleep, but you're in bed for nine hours, you have to choose a wake-up time. Let's say it's 7:00 and then you have to go to bed five hours earlier, 2:00 to s7:00. That's all you can give yourself, and you cannot stop with that schedule until you've slept for the majority of those hours. That's very hard for a sleepless person. And then once you've succeeded, all you get to add on is 15 more minutes of sleep, and then you have to sleep the majority of those hours for three nights running. This is always for three nights running, and the idea is to build up a enough sleep pressure to regularize yourself. You basically capitulate to exhaustion and you start to develop a rhythm. I couldn't stick with it. I was so kind of stupid and depressed with sleeplessness by the time I started it that it probably was impractical and I refused to take drugs to help me fall asleep at the exact right hour, which many clinics recommend. If you're going to go to bed and sleep from 2:00 to 7:00, take something at 1:30 so that you fall asleep at two. But I was afraid of being dependent on drugs, and you can really wean yourself if you do it for a limited amount of time. You can wean yourself anytime really, if you're shrewd about it and if you taper. But I think that I would tell people to try it and to try it sooner rather than later, and to be unafraid of doing it in combination with drugs so that the schedule worked. Taylor Wilson: Well, I am happy you brought up drugs. I did want to bring that up just in terms of what experts are saying about their impact. Even just drugs and alcohol kind of writ large, but sleeping pills specifically. What did you find in researching this in terms of drugs and alcohol? Jennifer Senior: Well, there's a real stigma taking sleep medication, and I'm frankly a little sick of it. I'm not sure why this is so very stigmatized. Like, oh, they're drug addict. They're hooked on sleeping pills. It's framed as addiction, and no one says that someone is addicted to their Ozempic, even though a lifestyle change could perhaps obviate the need. No one says that they are addicted... Oh, that person is totally addicted to their blood pressure medication, even though maybe a change in lifestyle would help change that. Or that they're addicted to their statins, So I sort of bristle. And those who prescribe these medicines say like, look, if the benefit outweighs the risk and they're used properly, sometimes the real side effect is just being dependent on these drugs, and there's a difference between dependence and addiction. A surprisingly small number of people who take these drugs regularly, like benzodiazepines, like Ativan and Ambien and Klonopin, all these things, a surprisingly small number, like 7% increase their doses if they take it every night. So that's very small. However, there are cognitive decrements over time... Or not decrements. It can interfere with your memory and it can increase your odds of falling as you get older. And those are, to me, the real persuasive reasons to get off. Taylor Wilson: I want to back up a minute here to talk about something many may not be aware of, and that's that historically, at least in some eras, people used to sleep in two blocks. What do you know about this? How did this function and really why did this kind of sleep pattern work for some folks? Jennifer Senior: Well, it was sort of, I think, natural. It seemed that this is, and it has not been proven everywhere, but there's plenty of both historical evidence and also some in a lab by this wonderful guy named Tom Ware that shows that if you sort of just put someone in a room, 14 hours of darkness, what will happen is that their sleep will naturally split into two. They'll sleep for a phase, wake up for a phase, and then sleep for a phase again. And historically, there's all sorts of evidence that people would sleep for a phase, get up and read for a while, do some quiet things, do light tasks, maybe sing, maybe have sex, and then go back to bed. So there seemed to be two phases, and this was much easier to do when midnight was actually midnight. You were going bed when the sun had set, or just after were you were tethered to the rhythms of the earth as opposed to a wired electricity run world. Taylor Wilson: What is something you wish you knew when you first started on this journey? Jennifer Senior: To get on it earlier and to not be as afraid... Cognitive behavioral therapy is, I think, often done in conjunction with taking something like Klonopin or Ativan or Ambien, and I was so petrified of becoming hooked on them that I didn't... I refused to take them and I couldn't get my sleep to contract as a result of it. My body was so completely dysregulated and confused about it was so all over the place that I really needed something to regularize it and stabilize it, and I flipped out, and I think if anybody goes and tries CBT, I and their practitioner says to them, and I'm going to have to be on their recommendation, do this in concert with a drug, because you really need it. Don't sit there and freak out and think that you can't or shouldn't, because it happens a lot and people freak out a lot.

Cloud Coffee: A Viral Drink That May Be a Healthy Choice
Another day, another viral TikTok drink. The beverage making the rounds right now is cloud coffee. The name alone sounds light and refreshing, which is exactly what many of us look for in a summer coffee drink. But what is actually in it, and is it any good for us? Cloud coffee is a chilled espresso drink made by layering Dalgona coffee over coconut water to yield a cold coffee beverage that is as beautiful as it is refreshing. Dalgona coffee, which originated in Macau in Southern China, consists of coffee powder, hot water, and sugar well beaten and layered over milk. It can be served hot or cold and it was named after the Korean candy that shares its caramel color. This whipped 'cloud' mixture is poured over a base of ice and coconut water, inspired by the coconut water americano that was also popular this spring. A coconut water americano is a simple drink that combines coconut water and espresso for a refreshing cold coffee beverage. Health Benefits From iced coffee to mocha protein shakes, the summertime coffee drinker in us is always happy with a chilled treat with a bit of caffeine. The question is, how healthy is this coffee swap for our chronic coffee drinkers? As with most things, it can be a good choice in moderation. A 16-ounce serving with 2 teaspoons of sugar contains about 150 calories, 5 g of protein, and even with a double shot of espresso, only about 120 mg of caffeine. That's comparable to the caffeine in a 12-ounce drip coffee. The addition of coconut water makes it a good source of potassium, a nutrient that is underconsumed by most Americans. Coffee is known around the world for its effect on cognition and energy levels, but it is also high in antioxidants. Caffeine and chlorogenic acid can promote a decrease in oxidative stress and improve inflammation. A pretty great way to start a hot summer day! While some recipes call for cream, I recommend whole fat milk to ensure adequate creaminess while incorporating more protein. Protein and fat both promote satiety, and a high protein diet can promote weight loss. Protein also has the added benefit of slowing down digestion and thus absorption of caffeine to allow for a slower uptake of caffeine over a longer time. This may help maintain energy levels and reduce any unpleasant side effects of caffeine such as elevated blood pressure. While I don't often recommend artificial sweeteners, the sugar in this drink could be swapped for aspartame or stevia without affecting the integrity of the whipped Dalgona coffee for those who prefer a sugar-free option. Maybe Not for Everyone While such a beverage is likely to be a refreshing treat for most, it may not be appropriate for all. Caffeine-containing beverages may not be the right choice for those prone to gastrointestinal issues like irritable bowel syndrome with diarrhea due to the stimulating effects of caffeine on the bowel or on those with high blood pressure due to its properties as a vasoconstrictor. Caffeine is a well-known diuretic, so I typically recommend limiting caffeine-containing beverages to no more than 2 or 3 a day, especially during the warm summer months when we may be more at risk of dehydration. Healthy and Refreshing Alternatives As cloud coffee may not be the right choice for everyone, I always like to have a few alternatives that are either low in caffeine or caffeine-free to encourage hydration. I have many clients who drink coffee all day long, so I have a couple of tricks to help them stay hydrated without completely giving up their caffeine or adding a lot of sugar. Green tea: Green tea has less than half the caffeine that coffee does and significantly more antioxidants, most in the form of epigallocatechin gallate that has been shown to promote weight loss and improve glucose metabolism. Hibiscus tea: Hibiscus tea is caffeine free and may help to improve mild hypertension. Caffeinated sparkling water: Many brands have less caffeine per serving than a cup of coffee and can also be a great substitute for chronic soda drinkers. Iced coffee with a protein shake: This may be especially helpful for those who are in the habit of drinking several cups of coffee a day. Mix 8 ounces of cold brewed coffee with a 12-ounce protein shake for less caffeine over several hours to stay focused while decreasing the unpleasant side effects of caffeine intake. Ultimately, I want my clients to drink water for hydration in the warm summer months. But, if a fun and refreshing coffee drink like cloud coffee has them excited and offers a few health benefits as well, I'm on board.

A Ring and a Smart Bed Tracked My Sleep for 30 Nights. Here's What I Learned
Did you know CNET has a dedicated sleep team? Over the years, we've tested around 350 mattresses from dozens of brands. We've tried numerous bedding items, including pillows, sheets, blankets, comforters and more. We've researched and reviewed countless sleep-related products, from white noise machines and sleep masks to supplements and bedtime mocktails. If there's an obscure "sleep hack" trending on social media, you can bet we've given it a shot. CNET's sleep team tests and reviews much more than just mattresses. Cole Kan/CNET We aim to sort through the overwhelming amount of sleep-related information available online to find what works -- and help you avoid the things that don't. Everyone has varying health needs and sleep preferences, so there's no one-size-fits-all approach to enhancing sleep quality. Still, we do our best to back our conclusions with actual sleep data, which is why it's essential for us to use accurate sleep trackers. Our CNET sleep editors have tested various trackers over the years to find those that work best for each of us. Types of sleep trackers The most accurate sleep test is a polysomnography, which is conducted in a lab. It uses sensors to monitor physiological factors such as brain waves, eye movements, heart rate, etc. It's extremely precise -- but it's not practical for everyday use. Most people who receive a polysomnography only do so because they're being tested for a sleep disorder. While not as accurate as PSG and unable to diagnose sleep disorders, many other types of sleep trackers are available for everyday use. They come in all shapes and sizes, from wearable rings and watches to mattress covers or pads. Dr. Carlos Nunez, chief medical officer at Resmed, explains, "Many wearable devices allow you to track your sleep patterns, such as bedtime, wake time, how often you wake up at night and some even track your sleep stages, like REM. Tracking these metrics over time can offer insights into the quality of your sleep health and empower users to make lifestyle changes to improve sleep and overall health." As part of our 30-night mattress testing series, my partner and fellow CNET sleep expert Dillon and I have tested several trackers, including Whoop, Apple Watch, Garmin, Eight Sleep and Oura. We've found wearables generally more accurate than devices you lie on, such as sleep tracking bed frames or mattress covers. Given that information, I have to admit that I was surprised by the results of our experiment testing the Oura Ring against our Sleep Number smart bed. An example of the nightly sleep data provided by my Whoop band. Aly Lopez/CNET Comparing Oura and Sleep Number Dillon and I recently tested the Sleep Number ClimateCool smart bed. This high-tech setup uses integrated sensors and SleepIQ technology to monitor body movements, sleep data and biosignals such as heart rate, breath rate and heart rate variability. Read more: 90-Night Review of the Sleep Number ClimateCool Smart Bed The cover is pulled back to show the tracking sensors running across the top third of the Sleep Number smart bed. Aly Lopez/CNET It tracks sleep metrics such as total time in bed, restful sleep, restlessness, bed exits and the times you fall asleep and wake up. The Sleep Number app collects and displays all this information, providing actionable insights and tips to help you improve your sleep quality. Dillon and I began wearing the Oura Ring 4 while testing our Sleep Number bed. This allowed us to compare and contrast our sleep data and assess the accuracy of both. Oura is widely considered one of the most precise wearables for tracking sleep, thanks to its placement on your finger near the radial artery for heart rate sensing. It tracks more than sleep, monitoring your fitness and activity, menstrual cycle, stress levels and more. For this review, I'll focus on the sleep and biosignals offered by each. Dillon and I have been wearing Oura rings to bed each night to compare our data with Sleep Number. Aly Lopez/CNET Oura offers a bit more detailed sleep data than Sleep Number, including the time spent in light, REM and deep sleep. Knowing when and how much time you spend in each stage provides valuable insights into your overall sleep quality, especially if you struggle with insomnia or other sleep disorders. The symptoms of insufficient REM and deep sleep are similar. Oura's breakdown of these sleep phases can provide more helpful information if you struggle to get quality rest. However, it's important to remember that you shouldn't try to interpret this data on your own. "If you're interested in more advanced data like REM versus deep sleep, sleep apnea detection or unusual breathing patterns, consult your doctor. Sleep trackers are a helpful tool, but not diagnostic devices. Medical guidance is essential for interpreting deeper metrics or addressing potential sleep health concerns," explains Nunez. Sleep trackers compared Sleep Number vs. Oura Ring 4 Metrics Oura Ring Sleep Number Overall sleep score ✓ ✓ Total sleep time ✓ ✓ Time awake ✓ ✓ Time in bed ✓ ✓ Sleep latency ✓ ✓ Heart rate variability ✓ ✓ Heart rate ✓ ✓ Respiratory rate ✓ ✓ Movement ✓ ✓ Helpful insights ✓ ✓ Recovery index ✓ x Light sleep ✓ x REM sleep ✓ x Sleep efficiency ✓ x Body temperature ✓ x Blood oxygen ✓ x Readiness score ✓ x Bed exit x ✓ At the beginning of our test, I didn't have high expectations for Sleep Number's tracking capabilities. However, when comparing the numbers with Oura, the results were surprisingly similar (for the most part). As you can see in the nightly sample below, Oura reported 6 hours and 42 hours of total sleep, while Sleep Number reported 6 hours and 44 minutes. Oura said I spent 44 minutes awake, while Sleep Number reported 38 minutes of restlessness. While it's hard to pinpoint the exact moment on either app, both Sleep Number and Oura reported my sleep and wake times within minutes of each other. Comparison of my sleep data from the Oura Ring (left) and the Sleep Number ClimateCool bed (right). Aly Lopez/CNET/Oura/Sleep Number Oura indicated my total time in bed was 7 hours and 25 minutes, while Sleep Number noted 7 hours and 35 minutes. Sleep Number gave me a SleepIQ score of 80; Oura gave me a 78. As expected, there were nights when the data did not match this well. In those scenarios, Sleep Number almost always displayed the more generous sleep scores and total time slept. Part of this discrepancy is because the Sleep Number smart bed occasionally assumes I've fallen asleep while watching television or reading, while Oura recognizes I have not yet entered dreamland. The bed may sometimes mistake Dillon's body movements or our dog's as mine, whereas our Oura rings don't have that issue. Read more: I Tested Three Sleep Trackers for 30 Days. Here's the One I'd Actually Use Sleep data compared External factors occasionally affected our sleep quality, resulting in data that didn't accurately reflect Oura or Sleep Number's tracking capabilities. An example is when I'd fall asleep on the couch and then move to the bed in the middle of the night. There were a few nights when I put my ring on its charger and forgot to put it back on before falling asleep. Additionally, factors like illness or menstrual cramps sometimes make me uncomfortable enough to sleep somewhere other than our smart bed. I excluded these nights to ensure the accuracy of this comparison. As a result, the sleep data presented here is not perfectly consecutive. Instead, to paint a better picture of how they track, it includes 30 nights of solid sleep on our Sleep Number smart bed while wearing Oura. Using both trackers for 30 nights, Oura reported an average total sleep of 7:35 hours (7.58), and Sleep Number reported 7:36 hours (7.60) -- just one minute difference. Aly Lopez/CNET For 30 nights using both sleep trackers, the average total sleep reported was only one minute apart: 7 hours and 35 minutes according to Oura, and 7 hours and 36 minutes according to Sleep Number. Both reported an average of exactly 1 hour of restlessness or time awake per night. Sleep Number gave me an average sleep score of 86, and Oura gave me 82. The health metrics tracked were also similar: Sleep Number reported my average resting heart rate as 53, and Oura indicated it as 52. Both trackers registered an average breath rate of 17. Oura reported my average heart rate variability to be 64, while Sleep Number reported it as 124. This discrepancy isn't necessarily because one brand is more accurate than the other, but because they calculate HRV differently. Both measure the time intervals between heartbeats throughout the night, but Oura uses a method called Root Mean Square of Successive Differences, while Sleep Number uses Standard Deviation of NN Intervals. Regardless of how it's calculated, higher HRV numbers are considered better, indicating good recovery and physical adaptability. Lower HRV numbers can be indicative of high stress levels, dehydration, alcohol consumption, poor sleep and more. Here's an example of the biosignals reported in Sleep Number's monthly summary. Aly Lopez/CNET/Sleep Number Why does tracking your sleep matter? As Vanessa Hill, PhD, sleep research and specialist, explains, "Tracking your sleep can offer helpful insights into what happens after your head hits the pillow. For many of us, sleep can feel poor quality, maybe because of fragmented sleep or nighttime awakenings. Tracking can show whether you're actually getting the recommended 7 to 9 hours a night." Observing your biosignals over time helps explain how your habits and lifestyle impact your sleep quality and patterns. For instance, my sleep quality on nights after consuming alcohol, not exercising during the day or going to bed later than usual is always worse, and it's reflected in my lower HRV numbers on both trackers. "What's more valuable than a single night's data is looking at sleep trends over time. A month or more of sleep tracking gives a better picture of your overall sleep health," adds Hill. If you're just beginning your sleep tracking journey, making sense of all the numbers can be overwhelming. Nunez recommends starting with the following basics to help you build a consistent sleep routine and improve your sleep health overall: Sleep-wake times: Track what time you go to bed and wake up each day. Research shows that a consistent sleep schedule is key to improved focus, productivity and mood. Track what time you go to bed and wake up each day.

Time awake during the night: Frequent disruptions may signal restlessness or a potential health condition worth exploring with a medical professional.

Sleep interruptions: Noting events like snoring or movement can provide added context to your sleep quality. Noting events like snoring or movement can provide added context to your sleep quality. Trends over time: Focus on patterns, not a single night's data, to make more meaningful lifestyle changes. What sleep tracker should you use? The type of sleep tracker you should use largely depends on your personal preferences and the health information you're looking to uncover. If you're not a fan of wearing a device to bed, such as a wristband or ring, consider a sleep-tracking mattress cover or pad like the Withings Sleep Tracking Mat, which was chosen as the best non-wearable tracker by our CNET sleep editors. There are many types of sleep trackers on the market, as CNET sleep editor Caroline Igo shows here. Caroline Igo/CNET Nunez explains, 'When considering a sleep tracker, it's important to note there is no one-size-fits-all. When choosing one, you can consider: Comfort: You need to be able to easily sleep in it consistently. You need to be able to easily sleep in it consistently. Compatibility: Check that it works well with your smartphone or other devices to access the data without challenges.

Reliability: Some devices have been well-tested and approved by the FDA for sleep monitoring, while others are more general consumer products.

Ultimately, the best tracker is one you'll wear regularly, and that makes accessing and understanding your data simple.' The bottom line If you have a Sleep Number bed and are wondering how accurate the sensors are, I'm pleased to share that they appear pretty dang precise. I had not been expecting the results of this 30-night comparison between the Oura Ring 4 and Sleep Number ClimateCool smart bed to be so similar. Still, there's much more room for error with trackers like smart beds and mattress covers compared to a wearable worn tightly on your body. If you're looking for one of the more accurate sleep trackers, I recommend opting for a wearable like Oura or Whoop -- but as Hill put it, "Choosing a sleep tracker really comes down to comfort and budget. Choose what works best for you, including something you'll actually use."
