Here's why 90% of Americans don't sleep through the night, according to expert
In an annual survey by U.S. News, which was released in March, thousands of Americans weighed in on their sleep habits.
While the National Institutes of Health recommends seven to nine hours of sleep every night, 58% of people reported sleeping six to seven hours a night.
Meanwhile, one in five Americans (20%) reported only getting four to five hours.
The survey also found that 25% of respondents use over-the-counter or prescription sleep aids.
The largest finding revealed that 89% of U.S. adults wake up regularly during the night.
More than one in three (40%) Americans said they wake up often, even if it doesn't happen daily.
Sleep expert Wendy Troxel, PhD — a RAND Corporation senior behavioral specialist and licensed clinical psychologist in Utah — shared a few reasons Americans aren't sleeping through the night.
"Given the stress and uncertainty in today's world, it is not particularly surprising that a striking number of people are facing trouble staying asleep," she said in an interview with Fox News Digital.
Other health conditions like chronic pain — or sleep disorders such as sleep apnea or insomnia — can also disrupt sleep, according to Troxel.
Environmental factors like pollution and rising global temperatures can also contribute to "fragmented sleep," as temperature can manipulate the circadian rhythm, the expert added.
"As part of the circadian rhythm (which regulates sleep-wake cycles among other things), the body's core temperature naturally decreases at night, signaling that it's time to sleep," she said.
"If you wake up and can't get back to sleep, get out of bed and do something calming but distracting."
"A cooler environment facilitates this temperature drop, promoting deeper and more restful sleep."
The recommended temperature for quality sleep is between 65 and 68 degrees Fahrenheit, according to experts.
Troxel recommended using breathable bedding, wearing lightweight sleepwear and using fans or air-conditioning to regulate temperature.
"Investing in temperature-regulating mattresses or mattress pads can also help maintain a comfortable temperature throughout the night," she advised.
Troxel also named menopause as a "significant factor" for sleep disruptions, with about 60% of women experiencing restless nights during this transition.

"Hormonal fluctuations throughout the menstrual cycle and during menopause influence thermoregulation and can contribute to sleep disruptions in women," she said.
To prevent waking up in the middle of the night, Troxel shared that "one of the most effective strategies" is stimulus control.
"If you wake up and can't get back to sleep, get out of bed and do something calming but distracting, like reading a book or gently stretching," she suggested. "This can help break the habit of being awake and frustrated in bed."
"You want your brain to associate your bed as a sanctuary for sleep, not as a place for frustration and worry."
Troxel also encouraged people to resist the urge to check the clock in the middle of the night.
"Seeing the time at 3 a.m. only exacerbates stress and anxiety," she said.

The Mere Sight of a Sick Person Can Trigger Our Immune System
The mere sight of a sick person may set off an alarm system in your brain and body, even if they are too far away to infect you. A series of experiments using virtual reality headsets has now revealed just how "exquisitely sensitive" our brains are to symptoms of sickness. When participants saw a virtual avatar at varying distances showing clear signs of illness (like a feverish rash), their brains suddenly kicked into gear and their immune systems were put on high alert. When they saw a healthy, neutral-looking avatar, on the other hand, their brains did not show the same activation patterns, and their bloodwork lacked an immediate elevation in immune markers. Related: Some of these markers are known as innate lymphoid cells (ILCs). ILCs can spike in the blood when the body is directly exposed to a pathogen, but all it took in this case was the sight of a virtual infection and the mere prospect of exposure. "Together, these data show that ILCs react to infections not only when they are detected in the body but also when they are processed as a potential threat approaching the body," write the international team of authors, led by immunologist Sara Trabanelli from the University of Lausanne in Switzerland. When researchers used machine learning to statistically analyze the results of their experiments, they found that the brain's threat-detection activity could largely explain the immune response. After seeing a virtual sick person at a distance, the brains of participants lit up in a unique pattern, which was not seen when the avatar had a fearful expression or a neutral expression. The sick avatars that were furthest away elicited the strongest response from the brain's network. Interestingly, some of these activated areas are the same as those that can be triggered after a flu vaccine is given. The findings suggest that when the brain senses a looming threat, it responds rapidly, triggering activity in brain parts like the hypothalamus, which then communicate with the immune system. This gives the body time to put up a fight. The recent experiments took place among 248 healthy adults in total, and in one of the trials, participants wearing VR were asked to press a button when they felt a touch on their face. When their VR sets featured a virtual sick person, participants pressed the button faster upon feeling the touch than when they saw a neutral or fearful avatar. This suggests that their brains are primed because of the sight of sickness. The anticipation probably evolved as a fight-or-flight response, the researchers suspect, though they caution there's still a lot to resolve, including how perceived infectiousness and disgust interact. "These findings suggest an integrated neuro–immune reaction in humans toward infection threats, not solely following physical contact," conclude the authors.

3 myths about metabolism could be holding you back
EDITOR'S NOTE: The podcast Chasing Life With Dr. Sanjay Gupta explores the medical science behind some of life's mysteries big and small. You can listen to episodes here. (CNN)— Think speeding up your metabolism is key to losing weight? Metabolism has grown into one of the biggest buzzwords in the wellness industry — a tricky code that, if deciphered, is believed to unlock the secrets of weight loss and overall health. Despite the term's ubiquity, one scientist says many people don't understand much of how this basic bodily process works. 'They think it has something to do with how much food we can eat without gaining weight or something like that,' Dr. Kevin Hall told CNN Chief Medical Correspondent Dr. Sanjay Gupta recently on his podcast, Chasing Life. Hall wants to elevate metabolism for different reasons. 'Metabolism is just this incredible biochemical process that basically turns the food that we eat and the oxygen that we breathe into essentially … everything we are and everything we do,' he said. A leading nutrition and metabolism scientist, Hall is well-known for his research on contestants from the reality show 'The Biggest Loser' that helped explain what set participants who kept the weight off apart from those who gained it back. He spent more than two decades at the National Institutes of Health. His later work on ultraprocessed foods investigated its link to obesity, including one study that demonstrated it actively caused participants to overeat. Hall announced his early retirement and exit from NIH in April, citing censorship of how his research findings were communicated. He's now coauthor of the new book 'Food Intelligence: The Science of How Food Both Nourishes and Harms Us' alongside journalist Julia Belluz. Metabolism and weight loss enter conversations arm in arm, but this, according to Hall, can be reductive. 'I just find it incredibly frustrating sometimes that this idea of metabolism, this really beautiful physiological process that is so fundamental to life, is kind of talked about as, 'Oh well, if you take this supplement, you can boost your metabolism and lose weight,'' he explained to Gupta. You can listen to the full episode here. Is a faster or higher metabolism really the highway to weight loss? Hall is here to set the record straight, highlighting three misconceptions about metabolism that show there is more to it than meets the eye. Myth 1: People with obesity have slow metabolisms One common belief is that a slower metabolism results in a higher body weight. But mostly, Hall said, the opposite is true. 'Generally, larger people have faster metabolisms than smaller people,' he told Gupta. Hall attributed the pervasiveness of this myth to the way researchers designed early metabolism studies. Scientists initially tried to match up participants' caloric intake to their weight, but they didn't account for the fact that these calorie counts were self-reported. It turned out that those with obesity often underreported the number of calories they ate to a larger degree than their leaner counterparts. This, Hall said, 'led people to a conclusion that, well, if they're eating less calories and they're maintaining their weight, then they must be burning less calories. And maybe the reason why they have obesity is because they have slow metabolisms.' Modern technology now allows researchers to rely on data, not participants' own reports. 'When we actually directly measure people's metabolisms, people with obesity have higher metabolic rates on average than people who are lean,' Hall noted. But the myth that we should be boosting metabolism to treat obesity has stubbornly persisted — and has at times led to deadly consequences. When Stanford University researchers discovered that the chemical compound 2,4-dinitrophenol, or DNP, increased metabolism levels in the 1930s, they enthusiastically promoted it as a safe and effective tool for treating obesity. While DNP did boost metabolism, it also led to side effects that included blindness and death, causing federal drug regulators to quickly withdraw it from the market. 'Maybe,' Hall suggested, 'it shouldn't be too much of a surprise later to realize that with something so fundamentally important to life as metabolism, you can't just turn it up and turn it down with a pharmaceutical drug and not expect some pretty severe side effects, including death.' Myth 2: Metabolism slows down as we age Like weight, age might not affect metabolism as much as you may assume. 'It turns out that until you get to very advanced ages, we're talking 70s and 80s, it looks like our metabolic rate is roughly constant,' Hall said. There are, of course, changes in the aging body that can impact metabolic rates. People 'past the age of 30 or so,' Hall said, are 'tending to lose muscle mass or tending to lose lean mass, and they're tending to gain fat mass. And that alone is anticipated to result in a lower metabolism.' That's because lean muscle burns more calories than fat. But it's these age-related changes — that are not inevitable — and not age itself, that influence one's metabolism. 'Once you get rid of that effect … it doesn't seem like there's a fundamental aging effect to slow metabolism as, as we get older,' Hall concluded. A couple ways to combat the loss of lean muscle mass as you age is by engaging in twice-a-week strength training and getting enough protein in your diet (but no need to go overboard). Myth 3: A high metabolism is necessary for weight loss Another pillar of metabolism mythology is the idea that a slow metabolism is the enemy of continued weight loss. Interventions such as dieting are believed to slow metabolism to the point that you can't lose any additional weight. But keeping your metabolism from slowing down isn't the key to sustained weight loss, Hall said. In fact, it's just the opposite. 'The people who are most successful at losing weight and keeping it off are the ones who sport the slowest metabolisms or the greatest reductions in metabolism,' he said. 'It's kind of like stretching a spring, right?' The more intensely someone diets or exercises, the more weight they'll lose and the more their metabolism will slow down, he explained in his book. Hall's research showed that a slower metabolism 'didn't seem to determine anyone's ability to lose weight or keep it off in the short or long run.' By uncoupling metabolism from the weight loss conversation, Hall said he hopes everyone can appreciate the phenomenon for what it really is. Misinformation about metabolism 'has really distracted people, I think, from the real beauty of what this is,' he told Gupta. 'It's harnessing the continuous flow of matter and energy in our food and in our breath and powering every cell in our body, as well as the bodies and cells of practically every organism that we have ever encountered,' Hall said. 'It's a fundamental component of life, and it's just incredibly fascinating.' We hope these three insights help you understand your metabolism better. Listen to the full episode here.

HEPA air purifiers can help lower blood pressure, study finds
People whose homes are near busy highways may be able to reduce their blood pressure by running an air purifier with a HEPA filter, a study found. Just a month of air filter use cut systolic blood pressure by nearly 3 points in healthy adults who had slightly elevated blood pressure, according to the report published Wednesday in the Journal of the American College of Cardiology. Doug Brugge, the study's lead author and professor and chair of the department of public health sciences at UConn Health in Farmington, acknowledged that 3 points may sound like a small reduction. 'But the medical literature shows that even at that magnitude there can be a meaningful benefit in terms of reducing the risk of serious cardiovascular outcomes, such as heart attack and stroke,' he said. Nearly a quarter of Americans live near busy roadways, according to the new research. People may not realize they're being exposed to traffic-related air pollution because it's invisible, odorless and can be easily missed, Brugge said. Yet high levels of the tiniest particles found in traffic-related air pollution are known risk factors for developing high blood pressure and heart disease. Blood pressure is measured with two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). A reading of less than 120/80 mm Hg is considered normal. Almost half, or about 119.9 million, of adults in the U.S. have hypertension, or high blood pressure, according to 2023 estimates from the Centers for Disease Control and Prevention. To determine whether simply installing two portable, commercially available air purifiers with HEPA filters could improve heart health, Brugge and his colleagues sought healthy volunteers whose homes were near roadways that would expose them to elevated levels of the tiny particles from vehicle emissions, as well as particles associated with tires and brakes. The researchers randomly assigned 154 volunteers to two groups. One would have two HEPA filters in the most commonly used rooms in their homes — one in the living room and the other in the bedroom. The other would be given sham filters. Then the groups would be switched. After a month of living with HEPA filters, volunteers who had slightly elevated blood pressure at the beginning of the study saw a 2.8-point drop in systolic blood pressure, the top number that the American Heart Association considers the strongest predictor of future heart problems. In contrast, those living with the sham filters saw a 0.2-point drop. People with normal blood pressure did not see an effect from HEPA use. The type of air filters used in the study were comparable to ones consumers can easily purchase in a store or online, Brugge said. The new study is 'intriguing,' said Dr. Matthew Alexander, an assistant professor of medicine in the division of cardiovascular medicine at the Vanderbilt University Medical Center in Nashville, Tennessee. Not everyone's blood pressure changed, just those with systolic pressures over 120 at the outset, Alexander said. 'It was a modest effect, but a clinically significant one,' he added. 'And it would correspond to about a 6% reduction in the risk of adverse cardiac events, such as heart attacks, strokes or cardiovascular death.' Alexander would like to see more studies, ones with more participants and a wider range of blood pressures. As would Steven Chillrud, a pollution expert and a research professor at Columbia University's Lamont-Doherty Earth Observatory in Palisades, New York. It's likely that filtering would help even people who don't live near roadways since traffic isn't the only source of air pollution, Chillrud said.
