Why Do I Keep Waking Up at Night? Common Causes and How to Sleep More Soundly

You fall asleep without much trouble.

Then you look at the clock.

1:47 a.m.

You fall asleep again, only to wake up at 3:15. Maybe you need to use the bathroom. Maybe the dog moved. Maybe you heard a noise. Or maybe there seems to be absolutely no reason at all.

Then comes the frustrating part: your body is tired, but your brain has apparently decided the day should begin.

If this sounds familiar, you are far from alone.

Waking briefly during the night can be a normal part of sleep, and it tends to happen more often as we get older. The bigger question is whether you can comfortably return to sleep or whether those awakenings repeatedly leave you staring at the ceiling, checking the clock, and feeling exhausted the next day. The National Institute on Aging notes that sleep tends to become shorter and lighter with age and that older adults may wake more frequently during the night.

So, why do you keep waking up at night?

There isn't one answer. Nighttime awakenings can come from your sleep habits, stress, your environment, medications, physical discomfort, bathroom needs, or an underlying sleep or health condition.

Let's look at some of the most common possibilities—and what you can do about them.

Is It Normal to Wake Up During the Night?

Yes—to a point.

Sleep isn't one long period of unconsciousness. Your body moves through different stages of sleep throughout the night, and brief awakenings can occur.

As we get older, those awakenings may become more noticeable because sleep often becomes lighter. This doesn't automatically mean something is wrong.

The real concern is sleep quality.

The CDC describes quality sleep as sleep that is refreshing and relatively uninterrupted. Repeatedly waking during the night and regularly feeling tired despite spending enough time in bed are signs of poor sleep quality.

If you wake up, roll over and fall back asleep a few minutes later, it may not be much of a problem.

If you wake up several times every night and spend 20, 30, 60 minutes—or longer—trying to get back to sleep, it deserves more attention.

1. Stress May Be Following You Into Bed

You finally lie down, but your brain doesn't.

Tomorrow's schedule.

Money.

Work.

Family.

Something you should have said three days ago.

Something you need to remember three days from now.

Stress and changes in routine can contribute to insomnia, including difficulty staying asleep.

Sometimes you don't even feel particularly stressed when you go to bed. You may fall asleep easily because you're exhausted, only to wake later and discover that your brain is ready to resume processing everything you ignored during the day.

What can help?

Try creating a deliberate transition between your day and bedtime.

Rather than going directly from television, social media, work or problem-solving into bed, give yourself a period to wind down.

That might include:

• Dimming the lights.

• Reading something relaxing.

• Taking a warm shower.

• Listening to quiet music.

• Writing tomorrow's priorities down so you don't have to keep rehearsing them mentally.

• Putting your phone away before climbing into bed.

You don't need an elaborate nighttime ritual.

You just need to give your brain a reasonably consistent signal that the day is finished.

2. Your Sleep Schedule May Be Working Against You

Our bodies like consistency more than many of us do.

Going to bed at 9:30 one night, midnight the next and 1:30 a.m. on the weekend can make maintaining a regular sleep pattern more difficult.

Both the CDC and National Institute on Aging recommend maintaining a consistent bedtime and wake time as part of healthy sleep habits.

That doesn't mean you have to become obsessive about the clock.

It means that if nighttime waking has become a problem, consistency is one of the simplest things worth testing.

Try keeping approximately the same bedtime and wake time for a couple of weeks and see whether your sleep becomes more predictable.

3. Your Afternoon Coffee May Still Matter

For some of us, coffee isn't a beverage.

It's a food group.

Unfortunately, caffeine later in the day can interfere with sleep. The CDC recommends avoiding caffeine in the afternoon or evening, and the National Institute on Aging recommends avoiding caffeine late in the day.

And coffee isn't the only source.

Caffeine may also come from tea, soda, energy drinks, chocolate and other products.

If you're waking repeatedly at night, try moving your caffeine cutoff earlier for a couple of weeks.

You might discover that the coffee you thought wasn't affecting you actually was.

4. Alcohol Isn't Necessarily Helping Your Sleep

A drink in the evening can make some people feel relaxed or sleepy.

That doesn't necessarily mean it's helping them get high-quality sleep.

Both the CDC and National Institute on Aging recommend avoiding alcohol close to bedtime as part of better sleep habits.

If nighttime waking is a regular problem, alcohol is another variable worth removing temporarily to see whether your sleep improves.

The goal is not to guess.

Change one thing and pay attention to what happens.

5. You Keep Waking Up to Use the Bathroom

This is an especially common complaint:

"I don't know if I'm waking up because I need to pee—or peeing because I'm already awake."

And sometimes that really is the question.

Waking repeatedly during the night to urinate is called nocturia. Occasional nighttime bathroom trips may not be unusual, but frequent urination can sometimes be associated with fluid intake, medications, bladder problems, sleep disorders or other health conditions.

A few practical things are worth looking at:

How much are you drinking shortly before bed?

Are you drinking caffeine or alcohol later in the evening?

Are you taking a medication that increases urination?

Do you have other urinary symptoms?

If nighttime bathroom trips are frequent, new, worsening, painful or accompanied by other urinary problems, don't simply accept them as an unavoidable part of getting older. NIDDK recommends discussing symptoms such as waking to urinate with a healthcare professional.

6. Your Bedroom May Be Waking You Up

Sometimes we search for complicated biological explanations when the actual problem is:

The room isn't comfortable.

Light.

Noise.

A barking dog.

A snoring partner.

A television left on.

A room that's too warm.

Notifications lighting up your phone.

The National Institute on Aging recommends keeping the bedroom quiet and comfortable and reducing electronic screens around bedtime. The CDC similarly recommends a quiet, relaxing, cool sleeping environment.

Try looking at your bedroom as if you were designing it specifically for sleep.

Ask yourself:

What in this room could wake me up at 2:00 in the morning?

Then eliminate as many of those triggers as practical.

Of course, if you have dogs, you may have to negotiate the terms with management.

7. Pain and Physical Discomfort Can Interrupt Sleep

Back pain.

Arthritis.

Neck pain.

Reflux.

Congestion.

Muscle cramps.

Hot flashes.

A pillow that worked perfectly ten years ago but now seems to have declared war on your neck.

Physical discomfort can make it harder to remain asleep, and medical conditions become more common as we age. The National Institute on Aging notes that health conditions and medications are among the factors that can affect sleep in older adults.

If you're repeatedly waking because something hurts, burns, aches or feels uncomfortable, addressing the underlying issue may do more for your sleep than simply trying to make yourself sleep through it.

8. Your Medication Could Be Part of the Puzzle

Many people take medications every day without thinking about how the timing or side effects might affect sleep.

That's another reason persistent sleep problems are worth discussing with your doctor or pharmacist.

Older adults in particular are more likely to take medications and have health conditions that can affect sleep.

That doesn't mean you should stop taking a prescribed medication because you think it might be keeping you awake.

Don't change or discontinue prescription medications without discussing it with the appropriate healthcare professional.

Instead, ask whether the medication—or the time of day you take it—could be contributing to the problem.

9. Sleep Apnea Can Cause Repeated Awakenings

This one is important.

Obstructive sleep apnea can cause breathing to repeatedly stop and restart during sleep. Common warning signs include loud snoring, gasping for air and witnessed pauses in breathing. Daytime sleepiness and poor-quality sleep can also occur.

And you may not know you're doing it.

Often a spouse or partner notices the snoring, gasping or breathing pauses first.

Sleep apnea shouldn't be treated as simply an annoying form of snoring. If you regularly wake gasping or choking, have been told that your breathing stops during sleep, snore heavily and experience excessive daytime sleepiness, talk with a healthcare provider about being evaluated.

10. You May Be Dealing With Sleep-Maintenance Insomnia

Most people associate insomnia with lying in bed unable to fall asleep.

That's only one form.

Insomnia can also mean difficulty staying asleep or waking earlier than intended and being unable to return to sleep. NHLBI notes that waking often during the night is a common symptom, particularly among older adults.

Chronic insomnia generally involves difficulty falling asleep or staying asleep at least three nights per week for three months or longer.

If that's describing your nights, it may be time to stop thinking of the problem as simply "I'm a bad sleeper."

There are treatments and behavioral approaches that can help. The National Institute on Aging specifically notes that cognitive behavioral therapy can be helpful for insomnia.

Start With the Basics Before Making Sleep Complicated

Sleep has become an enormous industry.

Pillows.

Mattresses.

Apps.

Wearable trackers.

Supplements.

Special lights.

Sound machines.

Medications.

Some of those things can certainly have a place.

But before buying ten new products, start with the fundamentals.

The CDC and National Institute on Aging recommend many of the same basic habits: maintain a regular sleep schedule, create a comfortable sleeping environment, reduce nighttime screen exposure, exercise regularly and avoid caffeine, alcohol and large meals late in the day.

Try this simple sleep reset:

Keep a consistent bedtime and wake time.

Give your body a predictable schedule.

Reduce caffeine later in the day.

Experiment with an earlier cutoff.

Watch evening alcohol.

See whether eliminating it improves your sleep.

Make the bedroom sleep-friendly.

Cool, quiet, comfortable and dark usually beats bright, noisy and full of notifications.

Give yourself time to wind down.

Your brain may need a transition from daytime activity to nighttime rest.

Exercise regularly.

Regular physical activity is among the healthy sleep habits recommended by both the CDC and NIA.

Pay attention to bathroom patterns.

Especially if nighttime urination is becoming increasingly frequent.

Look for physical causes.

Pain, breathing problems, urinary symptoms and medication effects deserve attention rather than being written off as "just getting older."

Keep a Sleep Diary for Two Weeks

This may be one of the most useful things you can do.

Instead of trying to remember whether Tuesday was better than Thursday, write it down.

The National Institute on Aging recommends keeping a sleep diary for a couple of weeks when you're having trouble sleeping. Record when you go to bed, when you wake during the night, when you get up for the day, and factors such as caffeine, alcohol and exercise.

You could also note:

• What time you last ate.

• What time you stopped drinking caffeine.

• Whether you drank alcohol.

• Whether you exercised.

• How many times you woke up.

• Why you think you woke up.

• Bathroom trips.

• Approximate time spent awake.

• How you felt the next morning.

Patterns that seem invisible from one night to the next can become surprisingly obvious when you see two weeks written down.

What About Natural Sleep Support?

Once you've addressed the obvious causes, you may decide you want additional sleep support.

I personally prefer looking for approaches that support sleep without leaving me feeling sluggish the following morning.

I've also experimented with a melatonin-free CBN sleep product and documented my experience after using it consistently rather than judging it from one or two nights.

If you're interested in that side of the discussion, read:

LiveGood CBN Sleep Gummies Review: A Natural, Melatonin-Free Approach to Better Sleep

In that review I explain what I used, what is in the product, what I personally noticed, and why the ability to fall back asleep after being awakened became one of the biggest benefits for me.

My experience is just that—my experience. A product that works well for one person isn't guaranteed to produce the same results for someone else, and sleep problems caused by an underlying medical condition should be evaluated rather than simply covered up.

When Should You Talk to Your Doctor About Waking Up at Night?

Occasionally waking during the night isn't automatically a reason to worry.

But consider talking with a healthcare professional if:

• You're waking repeatedly most nights.

• The problem has continued for weeks or months.

• You're regularly exhausted during the day.

• You're falling asleep unintentionally during daytime activities.

• You snore heavily, gasp for air or someone notices pauses in your breathing.

• You regularly wake because you're short of breath.

• Pain repeatedly wakes you.

• You're urinating frequently during the night, particularly if the pattern is new or accompanied by other urinary symptoms.

• You suspect a medication may be interfering with sleep.

• Poor sleep is affecting your mood, concentration, work, driving or daily activities.

NHLBI specifically recommends speaking with a doctor when inadequate sleep begins affecting daily activities.

The Goal Isn't Just More Sleep—It's Better Sleep

There's an important difference between spending eight hours in bed and getting eight hours of restorative sleep.

You could go to bed at 10:00 p.m. and get up at 6:00 a.m., but if those eight hours contain repeated long awakenings, you probably won't feel like someone who enjoyed a full night's rest.

And that's why simply asking "How many hours did I sleep?" isn't enough.

A better question might be:

"How well did I sleep?"

Most adults need roughly seven or more hours of sleep, depending partly on age, but sleep quality matters too.

If you keep waking up at night, don't immediately assume that this is simply something you have to live with.

Look for patterns.

Improve the basics.

Pay attention to what your body is telling you.

And if something doesn't seem right, get it checked.

A better night's sleep may not come from finding one magic solution.

It may come from finally identifying what keeps waking you up in the first place.
