25 Things You're Doing That Would Horrify Sleep Doctors

These are the seemingly harmless habits that threaten to disrupt your sweet slumber.

It's no secret that a good night's sleep is important. Aside from giving your body the break it deserves after a long day, it can help maintain a healthy metabolism, keep your memory sharp, and promote the overall health of your brain, according to Harvard Medical School. However, despite our need for quality shut-eye, we all still engage in activities that stand in the way of sweet slumber, even in ways you may not entirely realize. From watching TV in bed to cuddling with your dog, these are the habits that would horrify any sleep doctor.

Leaving the lights on

Do you often find yourself falling asleep to the glow of a bedside lamp or the light emanating from your closet? Well, according to Rose MacDowell, the chief research officer at sleep accessories review site Sleepopolis, these light sources could be stopping you from achieving a good night's rest.

Even if a large light source isn't turned on, "light from outlets, cable boxes, and clocks can be enough to halt production of the sleep-promoting hormone melatonin, delaying or disrupting sleep and lowering sleep quality," MacDowell says.

Drinking alcohol before bed

Sure, a glass of wine may seem like a relaxing way to ready your body for sleep, but according to MacDowell, the substance has the habit of messing with your body's circadian rhythm and preventing you from entering into a satisfactory REM cycle.

"Alcohol of any kind too close to bedtime may help you get to sleep, but you'll pay for it later. Alcohol wreaks havoc on your circadian rhythm and causes awakening after its sedating effects wear off," she explains. "Alcohol causes the body to spend too much time in deep sleep and not enough in REM sleep, which can affect dreams and the processing of memories and emotions."

Keeping your bedroom too warm

As it turns out, your body is much more likely to settle into deep sleep when your bedroom is cool. "The body reduces its core temperature in preparation for sleep, making a warmer environment less conducive to slumber," MacDowell explains. "Because the body is less able to sweat and shiver during sleep, room temps that are too hot or too cold can result in the body waking up to regulate core and skin temperature."

So what's the sweet spot on the thermostat when it comes to sleep? According to the National Sleep Foundation, you should be setting your thermostat to anywhere between 60 and 67 degrees Fahrenheit.

Sleeping without socks on

Though sleeping sans socks can feel decidedly more luxurious, a 2018 study published in the Journal of Physiological Anthropology found that sleeping with socks on promotes longer and more gratifying sleep. According to the study, those who sleep with socks on can expect at least 32 minutes of extra sleep, in addition to the more restful shut-eye that comes from your body being better able to regulate its temperature.

Going to sleep and waking up at odd hours

Even if your career or lifestyle has you waking up in the middle of the night and going to bed in the middle of the afternoon, there is a healthy way to go about catching those Z's. MacDowell notes that as long as you keep your schedule consistent—as in, going to bed and waking up at the same time every day—you'll be able to achieve a healthy sleep routine.

"Sleep doctors recommend going to sleep and waking up at the same time every day, even on weekends, to help regulate your circadian rhythm and maintain consistent sleep patterns," she says. Unfortunately, that means your 10-hour sleep sessions on Sundays may have to come to an end.

Reading or watching TV in bed

Though you may enjoy reading a book or watching TV in bed, MacDowell warns that these activities will keep your brain active up until the point when you're attempting to settle into a restful night's sleep.

"Reading, watching TV, studying, or working in bed can stymie your efforts to sleep," she says. "The brain and body are sensitive to habit and routine. Use your bed for anything other than sleep and sex and you may condition yourself to associate sleep with waking activities."

Bringing your problems to bed with you

"If you lie in bed thinking about everything on your schedule for the next day, chances are your sleep will suffer," says MacDowell. "Sleep depends not just on your circadian rhythm and your level of fatigue, but [also] on your ability to quiet your thoughts and central nervous system. Ruminating can cause the release of stress hormones such as cortisol and adrenaline, which activate the nervous system and keep your brain on high alert."

To combat these restless thoughts, engage in some meditation or write in your journal. Expelling any thoughts that could impede upon your ability to relax will result in deeper (and better) sleep.

Staying in bed through bouts of insomnia

The next time a bout of insomnia leaves you lying awake in bed at 2 a.m. agonizing over your sleep-deprived future, MacDowell suggests getting up and moving your frustrations out of the bedroom.

"Lying in bed in frustration when you can't get to sleep or fall back to sleep after waking can condition your body to associate the bed with the inability to sleep," she says. "If you don't fall asleep or get back to sleep after 20 minutes, get up and read or engage in another quiet activity until you're ready to sleep."

Sleeping on the wrong sheets

The National Sleep Foundation recommends investing in the perfect set of sheets to make your sleeping experience more comfortable. According to the experts, you'll want to look at two factors: thread count and material.

The higher the thread count, the softer the sheets. And during the summer months, you'll never want to sleep on sheets that exceed a 400-thread count, as anything too high will trap heat and not allow your body to properly ventilate. Similarly, sheets made out of cotton, bamboo, and linen will keep your body particularly cool as you sleep.

Or sleeping in the wrong positions

According to experts at The Better Sleep Council, there are six sleeping positions that exist: fetal (on your side, curled up); yearner (on your side, arms outstretched); log (on your side); solider (on your back); starfish (on your back, sprawled out); and free fall (on your stomach, sprawled out). And simply by switching up your sleep position, you might discover that your sleepless nights are no longer.

The council says the best sleeping positions are those on your back and side, since sleeping on your stomach can put a strain on your back and neck.

Or sleeping on the wrong mattress

Improving your quality of sleep might be as simple as throwing out your old mattress and investing in a new one that will give your body the support it needs. "There's nothing worse than fidgeting all night on an old mattress, knowing you'll never get comfortable and waking up with a sore back or shoulders," MacDowell says.

"Everyone sleeps differently, and it's imperative to have a mattress that supports us individually," she notes. "Back sleepers tend to need a firmer mattress, while those who sleep on their side need a slightly softer mattress to conform to their bodies."

Working right up until bedtime

As researchers at Sleep Advisor point out, your brain needs time to decompress after a long day. That's why they advise against working right up until your bedtime—because otherwise, your brain will still be operating at a million miles an hour when you're trying to power down. Even if you do have to work late, be sure to give your mind a brief break before you inevitably decide to settle in to slumber. The time between those two activities will ensure that your active brain doesn't keep you up all night.

Hitting the snooze button

Even if hitting the snooze button at least once in the morning has become a part of your routine, the experts at Sleep Advisor say that you could be harming your sleep schedule.

"Even though it's hard to wake up first thing in the morning, hitting snooze won't provide you with restful sleep," they explain. "You'll probably doze for a few minutes in light sleep and then be jarred awake moments later. By the time you do finally get up, you're more likely to be groggy and irritable than if you had just gotten out of bed when your alarm first buzzed."

Exercising too late

Though your only opportunity to work out might fall just before bed, hitting the gym too late at night could be preventing you from having sweet dreams.

"Working out raises our adrenaline levels and heart rates, making it difficult to fall—and stay—asleep," says Terry Cralle, a clinical sleep educator and Saatva sleep consultant. "Instead of going to the gym or running on a treadmill, perform more low-impact activities such as Pilates or yoga. These activities will keep your adrenaline and heart rate stable, while still getting in the necessary exercise."

Scrolling through Instagram before falling asleep

As Cralle points out, scrolling through apps on your phone as you lie in bed has been proven to drastically disrupt your sleep cycle. That's why the expert says you should "ditch the social media scrolling" and instead, "put on a sleep mask and listen to a short podcast to catch up on the daily news."

Eating the wrong late-night snacks

At a certain point in the night, that half-empty container of cookie dough ice cream almost seems to be calling your name from the kitchen. But, according to Cralle, those late-night snacks high in fat and sugar could be what's preventing you from settling in to a restful sleep.

"Everyone enjoys a late-night snack, but certain foods can have a serious impact on your sleep cycle," she explains. "Foods high in fat and sugar, like chocolate, have been linked to less deep sleep and lead people to wake up more throughout the night. Instead of a late-night bowl of ice cream, take the time to eat foods that promote melatonin—a sleep-inducing hormone—such as cherries and yogurt."

Or eating big, heavy meals right before bed

As it turns out, eating a large bowl of pasta for dinner may reduce your likelihood of shut-eye. In fact, eating anything too heavy a few hours before your bedtime could result in stomach pain and heartburn that could cause you to toss and turn all night long.

"Try to make dinnertime earlier in the evening, and avoid heavy, rich foods within two hours of bed," notes HelpGuide. "Spicy or acidic foods can cause stomach trouble."

Staying indoors throughout the day

Though you should be limiting your exposure to light as you wind down for the evening, it's also important to take in as much natural sunlight throughout the day as you can, according to HelpGuide. After waking up, you should try heading out into the sunshine as early as possible, as natural light helps to kick your circadian rhythm into gear.

As if it isn't bad enough that smoking can shorten your lifespan, in a 2008 study published in the journal Chest, cigarette smoking was also linked to unsatisfying sleep. According to the researchers, cigarette smokers experience nicotine withdrawal during crucial points in their sleep cycle, causing them to get less restful, and often interrupted, sleep. So, to receive the best sleep possible (and improve your overall health), consider ditching your smoking habit immediately.

Taking caffeine-infused medications before bed

Pill bottles

Many over-the-counter pain medications, like Excedrin, contain high levels of caffeine that can seriously alter your sleep cycle, says the National Sleep Foundation. And other medications—like ones used to treat ADHD, asthma, and high blood pressure—can not only cause insomnia, but can prevent you from achieving a restful night's sleep.

So, before popping a pill to ease your migraine, be sure to examine the amount of caffeine present in each dose, as it could be the reason you're up all night. (And if you think that your prescription might be the root of your problem, talk to your doctor about switching medications.)

Inviting your pets to sleep with you

Despite the fact that sleeping with your pets can make you happier, a 2017 study published in the journal Mayo Clinic Proceedings found that sleeping separately from Fido increases your chances of securing the most restful shut-eye. After all, with your pet nearby, you're more likely to spend the majority of the night ensuring that you aren't accidentally kicking them in your sleep.

The good news? The same study found that having your pet sleep in your room does not infringe on your quality of sleep—so you can still throw your dog a bone by allowing them to drift off into dreamland just a few feet away from you.

Taking long naps

Though this might seem like pointing out the obvious, long naps can severely alter your sleep schedule. What's more, the Mayo Clinic points out that taking a nap during the day that lasts for more than 30 minutes can also make your insomnia and sleep quality worse.

To best reap the benefits of a nap—which include improved mood and reduced fatigue—ensure that they are short and sweet at 20 to 30 minutes.

Leaving your contacts in

Not only can the irritation from leaving your contacts in affect your quality of sleep, but, according to the National Sleep Foundation, it can also deprive your eyes of both a much-needed break and a healthy dose of oxygen.

So take the time to remove those contact lenses before you lay down to rest—your eye doctor and sleep doctor will thank you for it.

Sleeping in a noisy room

Noises that are erratic and uncontrolled can disrupt your sleep and keep you awake, says the National Sleep Foundation. In the presence of uncontrolled outside noises—like those that would come from a crying baby, road construction, or maybe even a snoring spouse—you're more likely to toss and turn. For the best sleep quality, use a white noise machine or soft music to lull yourself to sleep.

Consuming caffeine less than six hours before bed

The consumption of any sort of caffeinated beverage can affect your quality of sleep, according to the National Sleep Foundation—and not only if it's right before your bedtime. Six hours after consuming caffeine, half of what you've consumed is still in your body, leaving the energizing supplement to wreak havoc on your sleep schedule well after your last cuppa. In order to avoid the insomnia that caffeine can induce, try to restrict the amount of coffee and/or tea that you're consuming to the first half of the day. And for more ways to get the sleep of your dreams, here are the 40 Best Ways to Get a Good Night's Sleep.
