Hot sleeper? Here are the 9 best comforters for a sweat-free slumber
Comforters for hot sleepers quick picks
NASA-engineered cooling technology: Slumber Cloud UltraCool Comforter
Our favorite down comforter: Brooklinen Down Comforter
An affordable down-alternative option: Bedsure Premium Down-Alternative Comforter We wait all winter to bask in the warmer days of summer, but the one place many of us want to keep cool and comfortable year-round is the bedroom. And it makes sense because your core body temperature naturally drops while you sleep to help give you a restful night. If your sleep environment is too warm, it can interfere with your body's ability to cool down properly, according to Dr. Andrea Matsumura, board-certified sleep specialist and spokesperson for the American Academy of Sleep Medicine. 'This disruption in thermoregulation can throw off your circadian rhythm — your internal clock — leading to fragmented or poor-quality sleep,' she said.
Finding the right balance between cozy compression and cooling in your bedding can be frustrating. To prevent you from stripping every blanket off your bed in a sweaty rage, we consulted a sleep expert, two textile experts and our on-staff editors to round up a list of the best comforters for hot sleepers.
Slumber Cloud UltraCool Comforter
After a lifetime of buying whatever kind of bedding was on sale, I finally upgraded to this Slumber Cloud comforter a few years ago. I'm a hot sleeper by nature, and at the time, my stuffy NYC apartment was unbelievably warm year-round (thanks to the heat from the bakery directly below). With its NASA-engineered fiberfill that regulates your body temperature and a cooling nylon and spandex cover that feels silky against the skin, this comforter was a lifesaver both then and now. I love that it has some weight to give you a compressed and bundled-up feeling, but it remains cool, even when I pop a linen duvet cover over it for more style. I'm not the only one who loves it either; CNN Underscored deals editor Jacqueline Saguin is a fan too.
Rest Evercool Cooling Comforter
Made of a proprietary Evercool cooling fabric, this comforter promises to stay cool to the touch all night long and even claims to outperform other breathable bedding materials like cotton, bamboo and silk. Soft to the touch and lightweight, the comforter is made from a blend of cooling nylon and spandex. The fibers of the fabric are densely knitted together to drape over your body without trapping heat. It's also machine-washable and dryer-safe, which Matsumura said are features that can help keep your bedding more hygienic since hot sleepers tend to sweat more.
Brooklinen Down Comforter
This Brooklinen comforter is our favorite down comforter. CNN Underscored associate testing writer Joe Bloss compared the comforter, which has a 100% cotton sateen shell, to snoozing among the clouds. With 700-fill power, it's heavier than some other down comforters we've tried, but Bloss never felt overheated or sweaty while using it. Plus, it's available in three weight options — lightweight, all-season and ultra-warm — so you can choose the best fit for your preferences.Read our review
Cozy Earth Bamboo Viscose Comforter
If you're looking for an alternative to cotton comforters, Matsumura said bamboo also makes a great choice since it's breathable and won't trap heat like other synthetic fibers. This Cozy Earth comforter is a bit of a splurge, but it's made from 100% viscose from bamboo, which also has natural moisture-wicking properties to ensure you get out of bed feeling fresh.
Puredown Pro Ultra-Lightweight Cooling Down Comforter
Filled with a mix of white duck down and white duck feathers, this Puredown comforter has two mesh strips designed to enhance air circulation and ensure heat quickly dissipates when temperatures begin to rise. You can use this lightweight comforter by itself in the summer and layer it with extra quilts or blankets in the winter for added warmth.
Buffy Cloud Comforter
CNN Underscored testing and updates writer Michelle Rae Uy said the Buffy Cloud Comforter is the perfect all-season option for keeping cozy during Los Angeles winters and cool during the summer. This Buffy comforter is made with lyocell fibers. 'Lyocell, a material made from sustainably sourced wood pulp, is ultra-soft and is great at pulling moisture away from your body, which helps regulate your temperature through the night,' Inga Bleyer, head of marketing and communication at Oeko-Tex, said. And if all this cooling comfort wasn't enough, this machine-washable pick comes in 10 colors and earned a top spot in our comforters guide for its soft feel and sturdy construction.Read our review
Silk & Snow Down-Alternative Comforter
'Down and down-alternative fills vary in loft and warmth,' Bleyer said. 'If you're a hot sleeper, look for a comforter labeled as 'lightweight' or 'summer weight.' These typically have less fill, which means they trap less heat.' This Silk & Snow comforter is made with a microfiber fill that comes in lightweight as well as all-season and winter-weight options. Designed to feel just like real down, this comforter also has a 100% cotton shell, is hypoallergenic and is machine-washable so everyone can comfortably enjoy its coziness.
Bedsure Premium Down-Alternative Comforter
Comforter costs can quickly climb into the range of a few hundred dollars. If you're just looking for something to get you through the sticky summer months without costing a fortune, try this Bedsure comforter. With a double-brushed shell for a soft and smooth feel on the skin, this down-alternative comforter is also Oeko-Tex Standard 100 certified and free from substances that can be harmful to human health. In addition to classic white, you can also grab this comforter in six other colors, including black, purple, green and navy.
Sijo AiryWeight Cooling Eucalyptus Comforter
Made of eucalyptus fibers for cool, sweat-free sleep, this Sijo comforter is also gently weighted, so you can have calming compression to unwind at night without feeling stuffy. The eucalyptus fibers help absorb moisture quickly, making this comforter a great option for those who deal with sticky and humid summer nights. Due to overheating and sweating, hot sleepers can be more likely to stir awake during the night or find it difficult to fall asleep. For optimal health and well-being, the American Academy of Sleep Medicine recommends that your sleep environment be dark, cool and quiet — almost like a cave. Though what's comfortable for you will depend on your personal preference, Matsumura said you should generally keep your bedroom at a temperature of around 68 degrees Fahrenheit. If you still don't feel comfortable, you can try adding in a cooling fan or some blackout curtains to help cool off the space even more.
Material and fill
'If you're a hot sleeper, choosing the right bedding can make all the difference,' Matsumura said. 'The best cooling materials share a few key traits: They're breathable, moisture-wicking and promote airflow.'
Natural fibers like cotton, linen, silk and lyocell are some of the best options for hot sleepers, according to Bleyer, since they're breathable, moisture-wicking and allow for better airflow. Matsumura recommends hot sleepers stay away from heavy, non-breathable materials like flannel or fleece, as well as synthetic-only fabrics that tend to trap heat during the night.
The fill of your comforter also plays a role in keeping you cool, since it dictates how well air can circulate through the material. Bleyer recommends looking for comforters labeled as 'lightweight' or 'summer weight' as these tend to be packed with less fill. Matsumura added that it can also be a good idea to look for moisture-wicking fabrics that can draw sweat away from the body as you sleep.
Care
Care is also essential for ensuring that your bedding lasts longer than one season. Bleyer recommends avoiding washing comforters with fabric softeners as they can coat the fibers and reduce breathability. Fabrics like lyocell and silk can be washed on a gentle cycle with cold water and mild detergent. Bleyer said materials like linen and cotton can handle regular cycles, but still prefer cooler water settings and low heat when drying to help preserve their natural structure.
When the summer ends, you'll want to make sure your seasonal bedding is well stored for the off-season too. 'When storing, keep bedding in a breathable cotton bag rather than plastic to prevent trapping moisture that can cause mildew or fabric breakdown,' Bleyer said. 'As for durability, linen and cotton tend to get better with age if cared for properly; think softer, cozier and still breathable.'
The following FAQs have been answered by sleep expert Dr. Andrea Matsumura and textile experts Inga Bleyer and Preeti Arya.
What is the best material for bedding for hot sleepers?
What is the best material for bedding for hot sleepers?
For hot sleepers, Matsumura recommends looking for bedding made with breathable, natural materials like cotton, bamboo or linen, and avoiding heavier fabrics like fleece and flannel or synthetic-only fabrics that trap heat.
Bleyer also recommends natural fabrics, noting that cotton, especially with a percale weave, is light and crisp for sleeping. 'Linen is a bit more textured, but it's great for hot sleepers because it's super breathable and has natural thermoregulating properties,' Bleyer said.
Are quilts, blankets or comforters best for hot sleepers?
Are quilts, blankets or comforters best for hot sleepers?
Ultimately, your choice of bedding boils down to personal preference. Hot sleepers can find success using comforters, so long as they're made of breathable materials and allow for good airflow. But Matsumura said that if a hot sleeper still feels too warm under a comforter, they can opt to use lightweight sheets or blankets that are easier to remove from the body and can better help them stay cool.
Our experts agreed that natural fibers are better at keeping you cool than synthetic ones, but Preeti Arya, an assistant professor of textile development and marketing at the Fashion Institute of Technology, said that no matter what kind of fiber is used to fill a comforter or duvet, a fluffy spread will still trap some amount of heat. For those looking to be ultra-cool, Arya recommends using 'flat throws, thick sheets or duvets without any stuffing or filling.'
Are down comforters good for hot sleepers?
Are down comforters good for hot sleepers?
Yes, hot sleepers can use down comforters. Matsumura recommends shopping for a down or down-alternative fill that is lightweight. She also recommends looking for comforters made with moisture-wicking fabrics or that have specific cooling properties to better aid hot sleepers.
Since hot sleepers tend to be more prone to sweating during the night, Matsumura also said it's a good idea to look for comforters that are machine-washable, both to keep your sleep setup more hygienic and make regular cleaning easier.
What else can I do if I still feel hot at night?
What else can I do if I still feel hot at night?
If you're still struggling to cool down at night, Matsumura has some other tips that might help you rest better. Make sure to drink plenty of water throughout the day to stay hydrated and avoid heavy exercise too close to bedtime, as exercise can raise body temperature.
If you wake up hot during the night, try changing clothes, swapping your comforter for a lighter layer or lowering the room temperature. You might also try taking a lukewarm shower before bedtime. 'A tepid shower can help dilate blood vessels to the skin; heat then is lost through the skin in the minutes after you exit the shower, allowing body temperature to drop,' Matsumura said.
After trying these at-home fixes, if you still find yourself sweating in the middle of the night, Matsumura said you should consult a sleep doctor, as these could be signs of a sleep disorder, such as sleep apnea.

Scientists Investigate What Happens If You Snort Moon Dust
Wondering whether snorting Moon dust will kill you? Don't worry: science is on it. A recent study conducted by a team of Australian researchers and published in the journal Life Sciences in Space Research found that lunar dust is probably way less dangerous than space science previously feared — and, actually, might be less dangerous for humans than Earthborne air pollution. (Or, if you will: Earth dust.) For the study, the scientists focused on fine dust particles, or specks of dust that are tiny enough to tunnel far into the lungs. Using state-of-the-art simulations of lunar dust and testing those fabrications on human lungs, researchers determined that, like any dust, the lunar stuff can be irritating, but it doesn't put astronauts at risk of long-term oxidative stress or inflammation akin to what we might see from toxic air pollutants here on Earth. "Our findings suggest that while lunar dust may cause some immediate irritation to the airways, it does not appear to pose a risk for chronic, long-term diseases like silicosis, which is caused by materials like silica dust," Michaela Smith, a graduate student at the University of Technology Sydney (UTS) and the study's lead author, said in a statement. The research has been billed as a relief for the astronauts and researchers embarking — maybe? — on NASA's Artemis missions, which seek to establish a long-term human presence on the Moon. Which, of course, is already a difficult assignment, given that the Moon isn't naturally hospitable for human life (with the no-oxygen thing and everything.) If Moon dust — which is, uh, basically the whole lunar surface — were indeed toxic, that would be a seriously tricky hurdle for scientists to climb. "The results," study coauthor and UTS scientist Brian Oliver said in a statement, "contribute to the safety case for returning humans to the Moon." As for the question of whether actually snorting Moon dust Jordan Belfort-style would be a sound idea, the researchers say you probably could. But while it's unlikely you'd experience long-term illness as a result, you should be prepared for discomfort. "Any dust, if you inhale it, you'll sneeze, cough, and have some physical irritation," Smith's statement continued. "But it's not highly toxic like silica, where you end up with silicosis from being on a construction site for 10 years. It's not going to be something like that." As the adage goes: just because you can, doesn't mean you should. More on the Moon: Scientists Investigating Small Orange Objects Coating Surface of the Moon

First Pill For Obstructive Sleep Apnea Shows Promise In Phase 3 Study
The American Academy of Sleep Medicine has indicated that an estimated 26 percent of adults between ... More the ages of 30 and 70 years have sleep apnea. (Photo: Getty) You could say that it's difficult to mask the challenges that people with obstructive sleep apnea face every day. But if this pill from Apnimed, Inc. eventually gets approved by the U.S. Food and Drug Administration, it could give those OSA sufferers who are having trouble wearing a continuous positive airway pressure mask while sleeping another option. Apnimed recently announced rather eye-opening topline results from the SynAIRgy phase 3 clinical trial of their AD109 pill. A little over half (51.2%) of the study participants who took the once-a-day pill had a reduction in their OSA severity while nearly a quarter (22.3%) experienced achieved complete OSA control. Obstructive Sleep Apnea Affects A Quarter Of The Adult Population More options would probably be a welcome possibility for the over 25 million adults in the U.S. who suffer from OSA, based on the National Healthy Sleep Awareness Project. The American Academy of Sleep Medicine has indicated that an estimated 26 percent of adults between the ages of 30 and 70 years have sleep apnea. That may be an underestimate because people are kind of asleep when they are experiencing signs and symptoms of OSA. It could take someone else trying to share a bed with you to tell you that you are snoring or even gasping for breath when you are asleep. OSA is one type of sleep apnea. Sleep apnea is when you repeatedly stop and start breathing while sleeping. Its important to know if this is happening because breathing is sort of important. Sleep apnea can lead to sleep deprivation, which, in turn, can lead to daytime drowsiness and over the longer term various chronic medical conditions, as I've described previously in Forbes. One such condition is high blood pressure, which in turn can raise the risk of heart disease and stroke. OSA is when the apnea is due to your throat muscles relaxing too much and blocking your airway. That's why one possible sign of OSA is snoring, which can occur when air tries to pass through the narrowed airway. The following illustration shows what can happen to the airway with OSA: (Illustration: Getty) Here Are The Current Treatment Options For Obstructive Sleep Apnea All of the currently available treatment options for OSA are focused on one thing: keep that airway open as much as possible. Changes in sleep position could help. For example, sleeping on your side, particularly the left side, can keep the airway open better than sleeping on your back. the latter can allow your tongue and soft palate to collapse into your airway. One oft-mentioned treatment option is the CPAP mask. The name is a clue to what it does. You wear a mask that will continuously will blow air into your nose or nose and mouth. That air is supposed to provide positive pressure to keep your airways open, sort of like blowing air into one of those balloons that can become a balloon animal. Although a variety of such masks are available, wearing such a mask throughout the night may not necessarily be the most pleasant, comfortable or sexy thing. Another option is some kind of mouthpiece designed to keep the throat open during sleep. Some such devices thrust your lower jaw forward. Other such devices hold your tongue is particular positions. When OSA gets particularly severe, surgery may be needed. This could be surgery to remove excess tissue in the neck that may be blocking the airway or move forward the jaw bones to give more space behind the tongue and soft palate. Life-threatening cases of OSA may even require a tracheostomy, which is when a hole is made in your throat and a breathing tube is inserted there. Now you may have heard about one of the glucagon-like peptide-1 receptor agonists, Zepbound, getting FDA-approval for severe OSA. This would be mainly for folks who have OSA due mainly to obesity. Excess fatty tissue in the neck can indeed predispose you to OSA. Therefore, weight loss can be helpful in reducing OSA. However, many people suffer from OSA do not have excess body weight. For many, it's just the anatomy of the airway and the way the nerves happen to be working or not working that allows too much collapse of the airway. The Apnimed Pill Could Become The First Prescription Pull For Obstructive Sleep Apnea This brings us to how AD109 is supposed to work. The medication is a combo of 2.5 mg of aroxybutynin, a new type of antimuscarinic, and 75 mg atomoxetine, which inhibits the reuptake of the neurotransmitter norepinephrine, thereby increasing the time it spends in between nerves. These work to increase the nerve signals sent through the hypoglossal motor nucleus that control the muscles in the upper airway. The medication has already gone through more than 15 Phase 1 and 2 clinical trials. A Phase 2b clinical trial named MARIPOSA showed that those taking AD109 experienced statistically significant reductions in their AHIs. AHI stands for apnea-hypopnea index, a commonly used measure of how severe sleep apnea is. The AHI is the average number of apneas, which are complete pauses in breathing, and hypopneas, which are partial reductions in breathing, that happen per hour of sleep during a sleep study. Normally, this should be less than five. Having five to 14 such events per hour classifies you as having mild sleep apnea. When this goes up to 15 to 29, it's moderate sleep apnea. The severe range is 30 or more such events per hour. Next up was the SynAIRgy trial, a randomized, double blind, placebo-controlled, parallel-arm of the medication designed to extend for six months. It included 646 adult study participants with OSA who either couldn't tolerate or didn't want to use CPAP. Around half (49.1%) of the study participants were women. At the beginning of the trial, 34.4% had mild OSA, 42.2% moderate and 23.2% severe. Patrick Strollo, Jr., MD, Vice Chair of Medicine for Veteran's Affairs and a Professor of Medicine at the University of Pittsburgh School of Medicine. served as the study chair of SynAIRgy. Strollo described the results so far as 'highly encouraging." At the 26-week mark in the SynAIRgy trial, those taking AD109 every day had on average a 55.6% reduction in their AHI. As mentioned previously, 51.2% actually dropped in sleep apnea disease severity categories with 22.3% going to the no apnea category, namely less than five events per hour. Those taking AD109 also on average had improvements in the amount of oxygen they were getting into their blood via their lungs. There were also no AD109-related serious adverse events with the medication in general being well-tolerated. Topline results from a second Phase 3 clinical trial, LunAIRo, will probably be available by the third quarter of 2025. All of this means that the company is currently on track to submit a New Drug Application for AD109 to the FDA by early 2026. If it reaches the market, AD109 would be the first prescription pill specifically for obstructive sleep apnea—which, again, affects quite a lot of people out there, probably much more than people realize. So don't sleep on what happens next.

3 Reasons You Wake Up Just Before Your Alarm Goes Off, According to a Sleep Expert
Has this ever happened to you? You set your alarm for, say, 7:30 a.m., drift off to sleep, and in the morning your eyes shoot open at 7:28. You may be resentful that your body has robbed you of an extra two minutes of precious sleep—or you may be wondering whether you have a supernatural ability to tell time while unconscious. We asked a sleep medicine physician what exactly is going on when we wake up right before our alarm goes off. She gave us three explanations, and surprisingly, one of them does involve something of a Matsumura, MD, spokesperson for the American Academy of Sleep MedicineCongratulations—you may be waking up right before your alarm rings because you've got your sleep routine down pat. "If you go to bed around the same time every night, get at least seven hours of sleep, and wake up around the same time every morning feeling refreshed, then your body is in tune with its circadian rhythm," says Andrea Matsumura, MD, who specializes in internal medicine and sleep medicine. Our circadian rhythm, described as our 24-hour internal clock, tells our body when to sleep and when to wake up. It's partly controlled by a region of the brain that's sensitive to external cues, like light and dark. "When darkness falls, melatonin is released, which gets us drifting off to sleep. Light—like sunlight filtering in through your blinds—triggers your circadian wake cycle for the day," Matsumura explains. So keeping regular bedtime and wakeup hours, and especially properly cueing your body with dark and light, will help your circadian rhythm run like a professional orchestra—on time, every time. Related: Good Sleep Hygiene Promotes Better Physical and Mental Health—Here's How to Improve Yours You could be so nervous about sleeping through your alarm—you have a plane to catch or an early meeting, for example—that your body wakes you up prematurely. "When the body anticipates waking up earlier, it can release stress hormones like cortisol and ACTH in preparation for the day, even before the alarm goes off," Matsumura says. In this case, you might be waking up briefly throughout the night, not just in the minutes before your alarm, though you may not remember doing so. If this happens to you regularly and you're always waking up anxious and foggy-headed, your circadian rhythm could be out of whack. "When somebody is a night owl and goes to bed after midnight, say, but they have to wake up for work at 6 a.m., they'll develop this kind of hypervigilance in their sleep and feel like they're sleeping with one eye open," Matsumura says. Luckily, you can take steps to realign your circadian rhythm. Related: 8 Common Signs of Sleep Deprivation You Shouldn't Ignore This is a weird one: Some people may be able to will themselves to wake up at a certain time, Matsumura says. "There is neuroscientific research behind manifestation and the power of persuasion," she says. "We see it all the time with athletes. They've trained their brain to visualize an outcome on the field, for example, and have it become reality. So it's possible that people can develop the ability to wake up at a certain time without using an alarm clock." How exactly can we train ourselves to wake up when we choose? "I have no idea," Matsumura says. "That hasn't been studied. But we can extrapolate that the power of manifestation can help us adjust our sleep timing, as long as it's in line with our circadian rhythm." Try setting an intention tonight and see what happens! (But keep that alarm clock on just in case.) Read the original article on Real Simple
