More than 55% of people hit the snooze button daily — here's how it impacts your brain and body
Indulging in a little extra sleep in the morning courtesy of the snooze button is something many of us will be familiar with. But now, a new study has shed light on just how many people have this habit.
Looking at more than 3 million nights of sleep data from 21,000 people, the researchers found that more than 55% of sleep sessions ended with people pushing their snooze alarm for a few more minutes of shut-eye.
If that doesn't apply to you and you're someone who jumps out of bed at the first sound of your morning alarm, I take my hat off to you. Because even as a well-rested sleep writer with a full-time job in learning how to optimize my sleep, I still find myself hitting snooze at least once in the morning.
Maybe its because I sleep on an oh-so comfortable top-rated mattress so I can't resist an extra few minutes snuggled up in bed. But whatever the reason, hitting snooze is a habit I want to kick this summer.
So, as well as exploring this latest research, I spoke to Dr. Leah Kaylor, a licensed clinical psychologist specializing in sleep and trauma, about the risks of consistently hitting snooze, and what you should do to make that button less tempting.
Pressing snooze in the morning happens in over 55% of sleep sessions, according to a new study by scientists at Mass General Brigham.
Using data from the sleep analysis app Sleep Cycle, researchers analyzed the sleep habits of more than 21,000 people around the world over a six month period.

They looked at more than three million night's of data and found 55.6% of sleep sessions logged ended with a snooze alarm.
The researchers also found that the average snooze time was 10 minutes and 48 seconds, and that "of the sleep sessions ending with snooze alarm, snooze alarm was pressed on average 2.4 times."
Those who slept nine hours or more were more likely to hit snooze (compared to those who slept for 7-9 hours or less than 7 hours), while people who went to bed earlier weren't as tempted to snooze as late sleepers.
45% of participants hit the snooze button for 80% of their sleep sessions
The study revealed that the majority, 45%, of participants hit the snooze button for 80% of their sleep sessions, classifying them as 'heavy snooze alarm users'.
Snoozing activity varied between days of the week. Overall, more people hit snooze on typical working days (Monday through Friday), while the snooze button got more of a rest on weekends.
The researchers also found women are more likely to snooze than men, which could indicate further evidence of the gender sleep gap. The data showed women spent an average 11 minutes 30 seconds snoozing, while men spent an average 10 minutes 12 seconds.
A recent study showed that around one third of people don't reach the recommended sleep target of 7-9 hours a night. So it's not surprising that many of us appear to be trying to cram in an extra few minutes when our alarms sound in the morning.
But snoozing isn't the best way to handle a lack of sleep or sleep deprivation, as it causes more disruption in our natural sleep-wake cycle. According to the new study, experts say the sleep we get after hitting the snooze button is likely to be of poor quality.
"While it feels comforting in the moment, hitting snooze disrupts your natural waking process and can lead to sleep inertia — that groggy, heavy-headed feeling that lingers after getting out of bed," explains Dr. Kaylor.
This is because you're not getting "meaningful rest" during those extra 5 to 10 minutes, just "fragmented sleep that confuses your brain," she says.
So, what happens to your brain and body when you press snooze? While you might think an extra few minutes kip is a good thing, the reality is likely to be the opposite.
"Each time you snooze, your brain reinitiates part of the sleep cycle — often entering light or REM sleep, depending on timing," says Dr. Kaylor.
"But because you're not asleep long enough to complete a full cycle, your brain is abruptly interrupted."
The result? You may experience sleep inertia, reduced cognitive sharpness, moodiness, and even elevated blood pressure as your body keeps restarting the 'wake-up' process.
Rather than hitting snooze, these expert recommended tips can help you get out of bed with energy to take on the day...
Placing your alarm, be it your phone or a traditional alarm clock, across the room from where your bed is puts physical space between you and the snooze button, making it impossible to turn it off and roll over back to sleep.
You'll have to get up to turn it off, and once you're out of bed it's much easier to feel alert and get on with your morning routine.
The authors of the new study also noted that sleep experts suggest "setting an alarm for the last realistic wake time to allow for as much consolidated, uninterrupted sleep as possible."
One of my key sleep tips will always be sleep with your blinds open. As your bedroom slowly fills with light, you gradually wake up.
This allows you to reach the end of a sleep cycle, completing all essential sleep stages, without being jolted awake by a loud alarm. This way, you're more likely to wake up with energy as your sleep will have been more restorative.
If your schedule requires you to wake up before the sun, consider investing in one of this year's best sunrise alarm clocks, which simulate a sunrise inside your bedroom, creating a more gentle wake-up call.
Another way to help you wake up on time without hitting snooze is sticking to a consistent sleep schedule. This is where you wake up and go to sleep at roughly the same time each day.
Doing so helps to align your natural circadian rhythm so your body gets used to releasing sleep and wake hormones at certain times of day. A healthy circadian rhythm should see melatonin production drop off towards the morning, so you feel less sleepy.

Here's why you feel awful after going back to bed for that extra hour of sleep
If you've woken up way too early for no good reason, going back to bed for that extra hour of sleep may not be as beneficial as you'd hoped. Instead, you're better off just staying awake, because slipping back into sleep will leave you feeling groggy and agitated since you've disturbed your 90-minute sleep cycle. 'If you were to sleep till you woke up naturally, often, you'd be fine because you'd be in the natural cycle. But then, when you fall asleep and then your alarm wakes you up … you have a good chance of ending up awakening in a deeper sleep phase when you weren't meant to wake up,' Dr. Greg Mahr, a psychiatrist at Henry Ford Health, told The Independent. 'You feel really groggy because you haven't gone through the natural rhythm.' Changes in the brain are 'fairly clear,' he said, looking at recordings of brain activity. When you interrupt those deeper stages of sleep, it can take a while to recover, whereas, being woken up in other lighter stages of sleep does not yield the same results. This is true even if you technically get enough sleep. 'It's typically not listening to our body cycles and trying to override them because of our schedules and alarm clocks,' Mahr noted. Alarm clocks can play a major role in sleep health. Recent research has found that more than 50 percent of 3 million sleep sessions studied ended in a 'snooze.' People spent an average of 11 minutes between snooze alarms before waking and heavy snoozers averaged 20 minutes a day, according to Dr. Rebecca Robbins, a sleep scientist at Brigham and Women's Hospital and assistant professor at Harvard Medical School. 'Unfortunately, the snooze alarm disrupts some of the most important stages of sleep. The hours just before waking are rich in rapid eye movement sleep. Hitting the snooze alarm will interrupt these critical stages of sleep and typically only offer you light sleep in between snooze alarms,' she explained. How many alarms you set can also be a red flag, according to Johns Hopkins Medicine Dr. Rachel Salas. 'If you're a 10-alarm person, that is a huge red flag. If you have to hit the snooze button and you're not waking up, that's a red flag that something may be going on while you're sleeping that you're not aware of,' she explained. 'You might have an undiagnosed, untreated sleep disorder.' People might not be able to control their variable work schedules or environmental conditions. But, can they hack the system? Can you sneak a little extra sleep in without feeling the effects? Salas says you can. 'Taking a nap before 3 p.m. for less than an hour – ideally, 20 or 30 minutes – that's one way to pay back and not affect the other process that's important for sleep that runs with the circadian rhythm. It's called the homeostatic drive,' she said. Otherwise, you can get yourself in a vicious cycle of bad sleep. But there's one way to ensure you're waking up as fresh as can be. 'The best approach for optimizing your sleep and next day performance is to set your alarm for the latest possible time, then commit to getting out of bed when your first alarm goes off,' Robbins said.

The secret to a longer life could be this old-fashioned English breakfast
The best news in a long time is that a breakfast of scrambled eggs and fish — kippers, say, or smoked salmon — combined with a few cups of coffee isn't just a great way to start your day, but is also likely to make you live healthier and longer. So report two separate scientific studies. Israel-Iran clash delivers a fresh shock to investors. History suggests this is the move to make. I'm in my 80s and have 2 kids. How do I choose between them to be my executor? These defense stocks offer the best growth prospects, as the Israel-Iran conflict fuels new interest in the sector 'I'm 68 and my 401(k) has dwindled to $82,000': My husband committed financial infidelity and has $50,000 in credit-card debt. What now? 'He failed in his fiduciary duty': My brother liquidated our mother's 401(k) for her nursing home. He claimed the rest. Eggs — specifically egg yolks — and oily fish like herrings and salmon are rich sources of vitamin D, and new research published in the American Journal of Clinical Nutrition says that this vitamin, in particular, may help slow aging. Meanwhile, other research suggests that drinking up to 2½ regular cups of coffee a day can raise your chances of living longer and staying healthy — physically and mentally — in your senior years. What's not to like? The study on vitamin D, conducted among a population of older Americans by researchers at Mass General Brigham, the University of Massachusetts and the Medical College of Georgia, found that those who took a daily vitamin D supplement of 2,000 IU, or international units, a day — meaning 50 micrograms a day — experienced a significant benefit in a key area of cellular aging known as 'telomere shortening.' Telomeres are the crucial protective caps at the ends of our DNA strands (they are sometimes compared to the plastic caps at the ends of shoelaces), and they are critical to cellular health. They typically shorten as we age and as cells divide. 'We found that vitamin D3 supplementation significantly reduced telomere attrition over a four-[year] period … suggesting that vitamin D3 daily supplementation with or without n-3 FAs might have a role in counteracting telomere erosion or cell senescence,' researchers wrote. (This particular study found no health benefit from another prominent ingredient in oily fish, namely Omega-3 oils — but many others have done so.) Meanwhile, research unveiled at the annual jamboree of the American Society for Nutrition, held in the scientific hot spot of Orlando, Fla., finds that drinking up to 2½ cups of regular caffeinated coffee per day may help you live longer and healthier. Decaffeinated coffee and colas showed no benefits, they added. The researchers did not examine whether a healthy, life-extending coffee also includes, say, one of those extra-large 500-calorie desserts, complete with caramel syrup, sprinkles and whipped cream, which some people pick up every morning (at the drive-thru, so they don't have to walk to the counter). Hmm … what do you think? Some headlines have emphasized that the study found a health benefit only in women, but this is a bit misleading. The researchers didn't reveal a health benefit in men not because they couldn't find one, but because they didn't look. The study only involved following women — nearly 50,000 of them — over several decades. (One caveat is that some of the researchers involved in both studies teach at Harvard — so for about half of the U.S. population, this is probably just 'fake news.') The latest research adds to a growing accumulation of knowledge about what we should do if we want to raise our chances of living longer and healthier lives. Each individual study is open to challenges and queries, because they are always conducted in the real, outside world, where countless unmeasured factors will interfere with the results. You cannot genetically engineer 10,000 identical humans, keep them in a laboratory for 80 years and subject them to laboratory-condition tests over that time. But overall, the real-world results have tended to point in some clear directions. The big picture of how to lead a healthy lifestyle is best summarized by research into so-called blue zones, meaning areas of the world — from Okinawa, Japan to Sardinia, Italy — where scientists have found that people tend to live the longest and the healthiest lives. According to the Blue Zones Institute, based on what scientists and researchers have observed about people living in these areas, there are five key areas to focus on: eating a healthy diet; staying physically active; socializing with friends and family a lot; having some sense of purpose or higher belief; and doing things that lower stress. On the issue of food, the 'Mediterranean diet' tends to get the most scientific support: lots of fish, fruits, vegetables, nuts, legumes and whole grains; only small amounts of meat; and very little processed food or refined carbohydrates. I don't know if fish for breakfast is Mediterranean, or just old school. In Victorian England, breakfast staples in wealthier households included kippers and kedgeree. Kippers, also known back then as 'red herrings,' are smoked herrings. (You can buy them in cans in U.S. supermarkets, often from Canada. The contents can be heated in a microwave in seconds.) Kedgeree, almost unknown on our side of the Atlantic, is a cold dish involving fish, egg, curry powder and rice. Both may be acquired tastes. Personally, as I grew up with them, I find them both exquisite — and vastly superior to any sugared cereal. If these things make a comeback, as 'health foods' no less, it can only be good news. 'It might be another Apple or Microsoft': My wife invested $100K in one stock and it exploded 1,500%. Do we sell? My friend wants me to join in a political protest. I'm worried about my job. Am I a coward if I say no? My husband is in hospice care. Friends say his children are lining up for his money. What can I do? 'I'm not wildly wealthy, but I've done well': I'm 79 and have $3 million in assets. Should I set up 529 plans for my grandkids? My mother-in-law thought the world's richest man needed Apple gift cards. How on Earth could she fall for this scam?

Why sleeping on your back is the unhealthiest position — and the one exception when it's actually the best
Are you on the right side of history when it comes to your sleep position? How you sleep significantly impacts your health, affecting everything from breathing and digestion to spinal alignment and even wrinkle development. 5 Your sleep position affects your breathing, digestion, spinal alignment and even wrinkle development. – Advertisement People tend to sleep on their side, studies show. Lying on the back is the second most common position, with stomach sleeping a distant third. So, which are the best and worst sleep positions? The Post had snooze experts pick a side. The worst sleep position is … Advertisement 'Out of all sleeping positions, the worst one — backed by scientific evidence — would have to be sleeping on one's back,' Michael Gradisar, head of sleep science for Sleep Cycle, a smart alarm app and sleep tracker, told The Post. When you sleep on your back, gravity can pull your tongue and soft palate back into your throat. 5 Sleeping on your back may seem like the logical choice, but it comes with a bevy of downsides. weyo – This movement can narrow your airway, increasing the chances of the vibrations that cause snoring. Advertisement Even worse, the airway can collapse, leading to breathing pauses during sleep. That condition is known as sleep apnea. Because sleep apnea disrupts rest, it's been linked to irritability, mental health challenges, increased insulin resistance that paves the way for diabetes, high blood pressure, heart disease and stroke. Lying flat on your back also makes it easier for stomach acid to flow back into the esophagus, fueling heartburn. Advertisement 'The best sleeping position is the one that feels the most comfortable, such that you get the most sleep,' Gradisar said. 'If the most comfortable position happens to be on your back, then lesser quality sleep is better than very little sleep.' Still, it's not all bad on your back — in fact, many of us started sleeping in the supine position in infancy. 5 This is definitely not the best sleep position. Do not try at home! theartofphoto – The back sleep position is widely recognized as the safest way to reduce the risk of sudden infant death syndrome (SIDS) because it minimizes the odds of airway obstruction. Sleeping on your back also promotes spinal alignment, relieves sinus buildup and prevents wrinkles and breakouts because there's less facial contact with the pillow. The best sleep position is … 'Sleeping on the stomach, or the prone position, may cause strain on the neck and back,' Dr. Boris Gilyadov, associate medical director of The Mount Sinai Integrative Sleep Center, told The Post. 'Usually, the better position to reduce snoring and possible sleep apnea is sleeping on the side (left or right),' added Gilyadov, an assistant professor of medicine (pulmonary, critical care and sleep medicine) at the Icahn School of Medicine at Mount Sinai. Advertisement 5 Sleeping on the stomach may cause strain on the neck and back. Vasiliy – Sleeping on your side, particularly the left side, has several benefits beyond your airways. Catching zzz's on your left side allows the stomach and pancreas to rest in a natural position, enabling proper digestion. Advertisement And when you lie on your left side, your stomach is positioned below your esophagus, making it harder for stomach acid to flow back into the esophagus. Sleeping on your left side can also help facilitate lymphatic drainage because the lymphatic system is dominant on the left side. A well-functioning lymphatic system is crucial for the performance of lymph nodes and the prevention of swelling. Plus, side sleeping can allow your spine to decompress and align properly, alleviating back pain and stiffness. Advertisement 5 Sleeping on your left side has many upsides, experts say. fizkes – Pregnant women are often encouraged to sleep on their left side. Sleeping on the back can put pressure on the inferior vena cava, reducing blood flow to the heart and baby. Sleeping on the left side helps maintain optimal blood flow and can minimize the risk of stillbirth. Advertisement There are some drawbacks, though, to side sleeping. This position concentrates pressure on the shoulder you sleep on, potentially leading to pain and discomfort. Plus, consistently putting one side of your face against the pillow can lead to wrinkles and breakouts. Experts recommend placing a supportive pillow under your head and neck and perhaps a pillow between your knees to help keep your hips and knees aligned and reduce stress on your lower back.
