In short
- A review of studies in healthy volunteers found that alcohol at all doses helps people fall asleep faster but increases sleep disruption in the second half of the night.
- The NHS recommends not drinking alcohol, tea or coffee for at least 6 hours before bed, and says heavy meals or foods that are hard to digest can also affect sleep.
- For people with reflux symptoms at night, NIDDK says eating meals at least 3 hours before lying down may improve symptoms.
- A 2016 brain imaging study found that poor sleep on a first night somewhere new involves one brain hemisphere staying more alert than the other, and the effect wasn't seen on later nights.
- The NHLBI says sleeping much more on days off can upset your body's sleep-wake rhythm, even if it helps you feel better.
- The EPA advises keeping indoor humidity below 50 percent when using a humidifier, and cleaning portable units every third day.
To sleep better during the holidays, protect your wake time, keep alcohol and big meals a few hours away from bed, plan ahead for travel and guest beds, and fix the dry air in the bedroom. None of these needs to be perfect. Holiday sleep usually falls apart from several small things stacking up, so trimming two or three of them makes a real difference. Here's a plan for each.
Why is it hard to sleep well over the holidays?
Holiday sleep is hard because the season changes almost everything that normally keeps sleep steady. Bedtimes drift later, mornings start at odd hours, there's more alcohol and richer food in the evening, and many people sleep in a different bed or a different time zone.
Each of these has its own effect, which the sections below cover. The useful thing to know up front is that they compound. A late, boozy dinner in a guest room after a day of travel hits harder than any one of those alone.
How does alcohol affect holiday sleep?
Alcohol affects holiday sleep by helping you drift off and then breaking up the second half of the night.
Research: moderate (what this means)A 2013 review in Alcoholism: Clinical and Experimental Research looked at all known studies of alcohol and nighttime sleep in healthy volunteers. At all doses, alcohol shortened the time it took to fall asleep, made the first half of the night more consolidated, and increased sleep disruption in the second half. It also delayed the first period of REM sleep at every dose studied. That pattern explains the familiar experience of sleeping heavily after a party and then waking at 3 a.m.
The NHS puts it simply: alcohol can make you feel sleepy at first, but it can lead to poor sleep later in the night. It recommends not drinking alcohol, tea or coffee at least 6 hours before going to bed.
Alcohol also affects breathing. Cleveland Clinic says too much to drink before bed can relax the muscles that keep your upper airway open, which can cause snoring. If you share a bed, that matters for two people. Our guide to alcohol and snoring goes deeper.
A realistic plan for drinks
You don't have to skip the toast. Switch to water or something alcohol-free for the last part of the evening, so your final drink lands a few hours before bed. On nights with an early start the next day, keep it to one or two.
Do big holiday meals affect sleep?
Big holiday meals can affect sleep, especially when they're late. The NHS notes that heavy meals or foods that are hard to digest can affect sleep. For people with reflux, timing matters more: NIDDK says that if you have symptoms at night or when lying down, eating meals at least 3 hours before you lie down or go to bed may improve symptoms. It lists alcoholic drinks, chocolate, high-fat foods, mint and spicy foods among items commonly linked to symptoms, which reads a lot like a holiday menu.
The practical move is to eat the main meal earlier in the day when you can, and keep the late-evening plate lighter. If a big late dinner is unavoidable, give yourself as much time upright as you can before lying down. There's more on the after-dinner slump in does turkey make you sleepy?
How do late nights throw off your sleep?
Late nights throw off your sleep mostly through what happens the next morning. Sleeping in to make up for a late night shifts your body clock later, which makes the next bedtime harder too.
The NHLBI explains that lost sleep adds up as sleep debt, and that while sleeping more on days off might help you feel better, it can upset your body's sleep-wake rhythm. During the holidays, that can mean a week of drifting later and later, followed by a rough first morning back at work.
The fix is to hold your wake time roughly steady, within an hour or so of normal, even after a late night. Make up the difference with an earlier night or a short afternoon nap rather than a long lie-in.
How do you sleep well when you travel for the holidays?
You sleep well when traveling by protecting the trip itself and adjusting quickly on arrival. For trips across time zones, the NHS suggests getting plenty of rest before you travel, switching to the new time zone's sleep schedule as quickly as possible, setting an alarm so you don't oversleep, and going outside in the day because natural light helps your body clock adjust. It also advises not having too much caffeine or alcohol, which can make jet lag worse.
For short trips of 2 to 3 days, the NHS says you could try keeping your usual eating and sleeping times, so you don't have to change your schedule again when you get home. Our travel sleep kit checklist covers what to pack, including what to bring if tape or strips are part of your routine.
Why is the first night in a guest bed so bad?
The first night in a guest bed is often worse because your brain stays partly on watch somewhere unfamiliar. Sleep researchers call it the first-night effect. A 2016 study in Current Biology used brain imaging and sleep recordings to show that during the first night in a new place, one brain hemisphere slept more lightly than the other, and that lighter side reacted more to unusual stimuli. The degree of this imbalance tracked how long people took to fall asleep. The difference wasn't seen in later sessions.
So night two usually goes better. To help night one, bring what makes a room feel familiar: your own pillow, an eye mask, earplugs, or a white noise app. The NHS suggests an eye mask and earplugs for travel sleep too.
Can dry heated air disturb your sleep?
Dry heated air can disturb your sleep by drying out your nose and airways. Cleveland Clinic says that when the air is dry, your nasal passages get dry too, and that dry air can irritate your nose and lungs. Some people notice it as stuffiness, a sore throat or a dry mouth in the morning.
A humidifier can help, but it needs care. The EPA advises not humidifying above 50 percent, emptying and refilling portable units daily, using low-mineral water such as distilled water, and cleaning them every third day to limit the growth of microorganisms. A hygrometer lets you check the level. Our winter breathing tips cover more ways to handle dry air.
If dry air leaves you breathing through your mouth, or a stuffy nose has you snoring in someone else's house, that's where nose breathing support fits. A combined routine like the Titan Sleep System covers both the nose and the mouth in one nightly routine.
What does a holiday sleep plan look like?
A holiday sleep plan picks a few defaults you can keep even on busy days. Here's one that covers the biggest disruptors.
| Holiday disruptor | What it does | What to do |
|---|---|---|
| Alcohol | Faster sleep onset, more disruption later in the night | Last drink at least a few hours before bed; the NHS suggests 6 |
| Big, late meals | Heavy food can affect sleep; late meals can worsen night reflux | Main meal earlier; if you get reflux, eat at least 3 hours before lying down |
| Late nights | Lie-ins shift your body clock later | Keep wake time within about an hour of normal |
| Travel | Jet lag disturbs sleep for a few days | Switch to local time fast; get daylight; easy on caffeine and alcohol |
| Guest bed | First-night effect keeps the brain partly alert | Bring familiar items, eye mask and earplugs; expect night two to be better |
| Dry heated air | Dries nose and throat | Humidifier kept below 50 percent and cleaned regularly |
| Snoring | Alcohol and back sleeping make it more likely | Side sleeping, less alcohol, nasal strips for a blocked nose |
How do you stop snoring at a holiday gathering?
You reduce snoring at a holiday gathering with the same steps that work at home. The NHS lists sleeping on your side, not drinking too much alcohol and, for a blocked or narrow nose, nasal dilators or strips. Cleveland Clinic notes that back sleeping is more associated with snoring because the tongue can relax toward the back of the throat.
If you're sharing a room with family, the NHS suggests that a partner whose sleep is affected by your snoring can use earplugs, which works for a roommate too.
If you use mouth tape, skip it on nights you've had a lot to drink or feel unwell; our guide to mouth tape and acid reflux explains why. We don't recommend mouth tape for children. Keep it out of reach of young visitors.
Check this first. Skip mouth tape and see a doctor if you snore loudly, wake up gasping, have been told you stop breathing in your sleep, or can't breathe comfortably through your nose. More on safety
When should you see a doctor?
See a doctor if poor sleep carries on well after the holidays end, or if you notice warning signs of a sleep disorder. The NHS advises seeing a GP if you feel sleepy during the day, your breathing stops and starts while you sleep, or you make gasping or choking noises while you sleep, since you may have sleep apnea, which can be serious if not treated. Family members sharing a room often spot these first.
Get a nose that's blocked most nights checked rather than working around it. If you're pregnant, ask your clinician before using a new sleep product. For reflux that keeps waking you, talk to your doctor about treatment.
Our pick (paid partner): Titan Sleep System
For holiday nights when dry air, travel or a stuffy nose get in the way, our pick is the Titan Sleep System. We haven't tested or ranked sleep products ourselves; this is our recommendation, based on how Titan describes the system. It supports nose breathing; it won't undo a late night or a heavy dinner.
Titan describes the Sleep System as TitanAir Nasal Strips and Titan Bamboo Silk Mouth Tape together as one nightly system. Titan says the strips are drug-free external nasal dilators with flexible spring-loaded bands, placed just above the flare of the nostrils on the soft part of the nose, not the bony bridge, on clean, dry skin. Titan describes the tape as a soft, breathable bamboo silk strip worn horizontally across the lips, and suggests 20 to 30 minutes of daytime practice before the first night, which is worth doing at home before you travel.
Titan says every batch is third-party tested and certified PFAS-free, and the system comes with a 30-night guarantee and free US shipping. If a stuffy nose is your only problem, TitanAir Nasal Strips are sold on their own too.

Common questions
Why do I sleep so badly over the holidays?
Holiday sleep usually suffers from several things at once: later nights, irregular wake times, more alcohol, bigger and later meals, travel and unfamiliar beds. Each one is small, but together they add up. Research shows alcohol disrupts the second half of the night, and sleeping somewhere new can make the first night lighter.
Does alcohol help you sleep at holiday parties?
Alcohol helps you fall asleep but makes the rest of the night worse. A review of studies in healthy volunteers found it shortens the time to fall asleep but increases sleep disruption in the second half of the night. Alcohol also relaxes the airway muscles, which Cleveland Clinic says can cause snoring.
How long before bed should I stop eating?
If you get reflux at night, NIDDK says eating meals at least 3 hours before you lie down or go to bed may improve symptoms. For everyone else there's no firm rule, but the NHS notes that heavy meals or foods that are hard to digest can affect sleep, so an earlier, lighter evening meal is a sensible default.
Why can't I sleep in a guest bed?
Poor sleep on the first night somewhere new is common and has a name: the first-night effect. A 2016 study found that during that first night, one side of the brain stays more alert than the other, as if keeping watch. The effect wasn't seen on later nights, so the second night is usually better.
How do I get back on a normal sleep schedule after the holidays?
Go back to your usual wake time first, even if you went to bed late. The NHLBI notes that sleeping much more on days off can upset your sleep-wake rhythm. A fixed alarm, morning light and moving bedtime back toward normal over a few nights is usually enough to reset.
Can dry heated air make snoring or a stuffy nose worse?
Dry indoor air can irritate the nose and airways, which some people notice as stuffiness or a dry mouth by morning. A humidifier can help if used carefully. The EPA advises keeping indoor humidity below 50 percent and cleaning portable humidifiers every third day to limit mold and bacteria.
