Why Do I Keep Waking Up at 3 AM?

Sep 28

The other day, I woke up around 4:30 AM. This happens every once in a while. Usually, I roll over, pull the covers back up, and go right back to sleep.

Not this time.

On this particular morning, my brain apparently decided 4:30 AM was an excellent time to replay a few conversations, balance my checkbook, and start planning this year’s Christmas gathering. I mean, really, brain? At 4:30 in the morning? Brain, nobody asked you.

If you’ve ever found yourself lying in bed at some ungodly hour thinking about something that absolutely did not require your attention until daylight, you’re in good company. And here’s something you may not know: waking up during the night isn’t necessarily the problem.

Wait. We’re Supposed to Wake Up at Night?

Sort of.

Sleep isn’t eight straight hours of unconsciousness. Throughout the night, your brain moves through repeating cycles of non-REM and REM sleep. These cycles generally restart about every 80 to 100 minutes, and most adults go through four to six cycles a night.

Earlier in the night, we spend more time in deep sleep. As morning gets closer, we spend more time in lighter sleep and REM, and we can briefly wake between sleep cycles. Most of the time, you don’t remember it. You roll over, fluff the pillow, steal the covers back from your spouse, somehow relocate the dog who has taken up three-quarters of the bed (or is that just me who lets her dogs sleep with her?) and go back to sleep.

As morning approaches and sleep becomes lighter, you’re more likely to remember waking up. So if you occasionally look at the clock at 3:17 AM, roll over and fall back asleep, your sleep isn’t necessarily broken.

But I’m guessing that’s not why you are reading an article titled “Why do I keep waking up at 3 AM?” You’re probably here because you wake up and stay awake.

That’s a different story.

Why Do I Keep Waking Up at 3 AM Every Night?

Let’s clear something up first. There is no known biological alarm clock that goes off at exactly 3:00 AM.

I know. The internet has theories. Your cortisol is spiking! Your blood sugar crashed! Your liver is detoxing! Your hormones are broken! Maybe Mercury is in retrograde. I don’t know.

Some of those ideas contain little pieces of actual physiology, but waking at 3:00 AM doesn’t automatically tell us why you woke up. There are plenty of legitimate reasons sleep can be disrupted.

Hormones can absolutely be part of the picture, especially during perimenopause and menopause. Hot flashes and night sweats are obvious sleep disruptors, but the relationship is more complicated than you might think. Research has found that sometimes the awakening actually happens before the hot flash.

Stress, alcohol, pain, medications, room temperature and the increasingly urgent bladder that apparently came standard with adulthood can all disrupt sleep too. Repeated nighttime waking can sometimes point to a sleep disorder such as sleep apnea or restless legs syndrome.

That’s why I don’t want you diagnosing yourself from this article or from TikTok. If this is happening frequently, particularly if you’re exhausted during the day, snoring loudly, waking up choking or gasping, experiencing uncomfortable sensations in your legs, or noticing a significant change in your usual sleep, it’s worth investigating.

Like, seriously. One of the reasons I won’t treat someone for insomnia without first ruling out sleep apnea is pretty simple: if you have sleep apnea, I don’t want you to stay asleep if you stop breathing. So before you diagnose yourself with one of the theories you learned on TikTok, please rule out sleep apnea. I’d like to know you didn’t die in your sleep.

But there’s another possibility, and this is where sleep gets really interesting.

What Woke You Up May Not Be What’s Keeping You Awake

Imagine you’ve had an unusually stressful month and you aren’t sleeping well. After several bad nights, you start worrying about it. Tonight has to be better, so you go to bed early.

Except you’re not particularly sleepy yet.

Now you’re lying there waiting and trying to sleep, and eventually you check the clock. It’s 11:42. You check again. 12:18. Then 1:06.

And now we’ve entered sleep math: Okay. If I fall asleep RIGHT NOW, I can still get five hours and twenty-four minutes. Because apparently calculating your diminishing sleep opportunity to the minute is supposed to relax you.

The next morning you’re exhausted, so you sleep later. Maybe you take a nap. That evening you decide to go to bed early again because you have to catch up. Slowly, without realizing it, you’re changing some of the very behaviors that help regulate your sleep.

Meanwhile, your bed, the place your brain used to associate with sleep, is becoming the place where you lie awake, worry, scroll, calculate, problem-solve and desperately try to make yourself unconscious. That’s a problem because you can’t really force sleep. In fact, trying harder can sometimes make you more awake.

Anxiety can make this cycle even stronger. If your brain has learned that nighttime is when we worry, rehearse conversations, solve tomorrow’s problems, or wonder why we’re still awake, it can start becoming more alert instead of less alert when your head hits the pillow. And after enough bad nights, you can actually become anxious about sleep itself. You’re no longer just worried about work, your kids, money, or whatever started the whole thing. Now you’re worried about whether you’re going to sleep, how much sleep you’re getting, and how terrible tomorrow will be if you don’t. Unfortunately, anxiety and sleep are terrible roommates.

Nightmares can complicate things too, particularly for people who have experienced trauma. Sometimes the problem isn’t that you can’t sleep. Part of you may not feel completely safe going to sleep. Nightmares can repeatedly wake you, and eventually you may begin dreading sleep, delaying bedtime, or staying more alert at night because your brain has learned that sleep itself can feel threatening. That doesn’t mean you’re destined to keep having nightmares. There are evidence-based treatments for trauma-related nightmares, including approaches that specifically work with recurring nightmare content. But if nightmares are regularly waking you or making you afraid to sleep, that’s something worth addressing rather than simply trying to improve your “sleep hygiene.”

Something may have started the problem, like menopause, stress, illness, pain, grief, a medication, trauma, or a terrible month at work. But eventually, the original trigger and the thing maintaining the insomnia aren’t necessarily the same.

So, What Can I Actually Do to Sleep Better?

If you’re waking up during the night, there are a few things you can try. In fact, I’m going to give you a few examples of strategies we use in Cognitive Behavioral Therapy for Insomnia (CBT-I) and, more importantly, explain why they work.

CBT-I often takes a behavioral approach to changing sleep. Your brain learns from repetition and association. If you spend night after night awake in bed worrying, scrolling or desperately trying to sleep, your brain can begin associating your bed with being awake. If you sleep late after a bad night or take a long nap, you may also reduce some of the natural sleep pressure that helps you sleep the following night.

So rather than giving you another list of random sleep tips, let’s work with the systems that actually regulate sleep.

Keep a consistent wake time. Even after a rough night, try to get up around your usual time. Being awake throughout the day helps build sleep pressure, while a consistent morning schedule helps anchor your circadian rhythm. Yes, I am saying get up at the same time every single day. Even on the weekends. I’m not kidding. And this really does make a difference.

Stop watching the clock. You don’t need to know whether it’s 3:12, 3:26 or 3:41. Every time you check, calculate how much sleep you’ve lost and start worrying about tomorrow, you’re increasing the very alertness we’re trying to reduce. It might be helpful to just move the clock or your phone away from your bed so you won't be tempted to look at it.

If you’re wide awake and getting frustrated, get out of bed. Keep the lights low, do something quiet, and return when you feel sleepy. This is called stimulus control, and the idea is simple: we’re trying to strengthen the association between bed and sleep, rather than bed and the place where I reconsider every decision I’ve made since 1997. If you’re not back asleep within about 15 minutes, get up and do something analog that will bore you to death. And please, for the love of all things holy, do not—I repeat, do not—get on your phone.

Keep a sleep diary for a week or two. You don’t need perfect data. You’re looking for patterns: when you’re actually sleeping, when you’re awake, how much time you’re spending in bed and what seems to make things better or worse. In CBT-I, that information helps guide what we do next. There's an app called CBTi coach you can use. The best part is it's free. You can get it here: https://mobile.va.gov/app/cbt-i-coach

And perhaps most importantly, don’t turn one bad night into an emergency. The thought I HAVE to sleep feels perfectly reasonable when you’re exhausted. Unfortunately, urgency creates arousal, and arousal isn’t particularly helpful when you’re trying to sleep.

Those are just a few examples. CBT-I goes further and tailors the approach to the person, but you can see the basic idea: instead of trying harder to sleep, we change the conditions that help sleep happen naturally.

What If I’m Still Not Sleeping?

If you’ve tried making some changes and you’re still regularly staring at the ceiling at 3:00 AM, it may be time for more individualized help. That’s especially true if you’re having trouble falling asleep, staying asleep, or getting back to sleep at least three nights a week for three months or longer, and it’s affecting how you function during the day.

CBT-I is considered a first-line treatment for chronic insomnia. Research has consistently found that it can improve falling asleep, staying asleep, and overall sleep quality, with benefits that can continue after treatment ends. And despite all my talk about behavior, CBT-I doesn’t just address what you do around sleep. The cognitive part addresses what you think about sleep too: the worry, sleep math, catastrophizing about tomorrow, and the growing belief that I’m never going to sleep or I can’t function unless I get eight hours. Those thoughts can increase anxiety and keep your brain on high alert when what you really need is for it to stand down.

That’s an important difference from sleep medication. Medication can certainly have a role in insomnia treatment, but CBT-I is designed to address the thoughts, behaviors, and patterns that may be helping keep the insomnia going.

Our Better Sleep & Tranquil Nights CBT-I Program

At Every Girl Living, our CBT-I program generally lasts eight to twelve weeks, and you’ll meet weekly with a CBT-I-trained therapist. We allow a little extra time because sometimes the thing keeping you awake isn’t just insomnia. Stress, anxiety, depression, grief, trauma, menopause, relationship problems or whatever else your brain has decided to discuss with you at 3:17 AM may need some attention too.

That’s where our integrative approach comes in. As we work on your sleep, we’ll also incorporate into your Roadmap for Living Well ways to address the other things that may be contributing to the problem. If anxiety is keeping your brain on high alert, we work on the anxiety. If trauma and nightmares are disrupting your sleep, we address the trauma. If depression, stress, relationships, or changes in your body are part of the picture, we don’t pretend those things stop existing when you go to bed. We look at the whole picture because sometimes getting you back to sleep means addressing more than sleep.

We’ve also created the Better Sleep & Tranquil Nights: CBT-I online course to accompany you through the program. It supports the work you’re doing with your therapist between sessions with instructional videos, practical exercises, guided meditations, and opportunities for reflection.

And because we’re Every Girl Living, we’ve added a few extras. You’ll have access to Yoga for Better Sleep online course, along with our Guide to Preparing for Dreamy Nights: Moon Milk & Winding Down, with recipes and ideas for creating a bedtime routine you might actually look forward to.

The goal is pretty straightforward: we want to help you get back to sleep.

And Tonight, If You Wake Up at 3:17 AM…

Remember that waking up isn’t automatically a catastrophe. Your brain naturally moves through different stages of sleep throughout the night, and brief awakenings happen. You don’t need to immediately check the clock, calculate how many hours you have left, solve your marriage, reorganize your business or plan Christmas.

Give sleep a chance to happen again.

And if sleep has stopped being simple if waking up night after night has become your normal it may be time to stop trying harder and start figuring out what’s actually keeping you awake.

And please don’t plan Christmas at 3:17 AM.

Trust me. It can wait until morning.
