The 3 A.M. Wake-Up

3:07 a.m. Again.

You didn't plan to wake up, but here you are, staring at the ceiling while your mind replays yesterday, worries about tomorrow, and starts checking off a to-do list you never meant to think about in the middle of the night.

If that sounds familiar, you're not alone.

In this episode of Healthspan on Her Terms, we're exploring one of the most common questions I hear from women after 35: Why do I keep waking up at 3 a.m.?

You'll learn why waking briefly during the night is actually normal and why the real challenge is when your brain and body can't settle back into restful sleep.

We'll discuss:

• How changing estrogen and progesterone influence sleep during perimenopause and menopause
• Why hot flashes and night sweats can quietly disrupt your sleep, even if they don't fully wake you up
• When blood sugar may contribute to nighttime waking and why it isn't the answer for everyone
• How stress, your nervous system, sleep apnea, pain, medications, alcohol, light exposure, movement, and mental health all work together to influence sleep

Most importantly, we'll talk about why better sleep isn't about finding one hormone or one culprit. It's about recognizing patterns, supporting your circadian rhythm, and giving your body what it needs to recover.

If you've been caught in the 3 a.m. cycle, I hope this episode helps you better understand what your body may be trying to tell you and gives you practical strategies to support healthier, more restorative sleep.

The 3 A.M. Spiral

Speaker 0:00

Have you ever found yourself staring at the ceiling, looking over at the clock, and seeing the same number again three hundred seven AM or maybe it's two hundred forty eight AM or three thirty six AM? You weren't planning to wake up, you certainly didn't want to wake up, but now you're awake and your mind immediately starts working, and you think about tomorrow's schedule, the conversation you need to have, your kids, your parents, your finances, the laundry, the emails you forgot to answer, and the longer and longer list there is. The longer you lie there, the more awake you become, and eventually you start wondering, what's what is wrong with me? If this sounds familiar, you're not alone. One of the most common complaints I hear from women during menopause and perimenopause isn't difficulty falling asleep. It's waking up in the middle of the night and struggling to get back to sleep. Some people immediately blame cortisol, others blame hormones, and some think it's blood sugar. The truth is it could involve any of those, and often it's several of them working together. Today we're going to talk about why sleep changes during midlife, why waking up at 3 o'clock in the morning is so common, and what your body may actually be trying to tell you. Welcome back to HealthSpan on Her Terms. I'm Dr. Sheri Erwin, a doctorate prepared nurse practitioner, certified integrative clinician, and founder of Root and Remedy Integrative Care. If you're new here, welcome. This podcast is all about helping women better understand what their bodies are trying to tell them so they can make informed decisions about their health and create a longer, healthier, more vibrant life. One of the things we've been talking about over the past several weeks is how our bodies communicate through symptoms: fatigue, hair loss, weight changes, brain fog, stress, and today, sleep. If you've listened to the last few episodes, you've probably noticed something that's common among them. Your body isn't sending random signals. It is trying to get your attention. Not because it's working against you, but because it's constantly adapting to what's happening both inside and outside your body. Over the last few weeks, we've talked about why normal thyroid tests don't always explain persistent symptoms. We've explored why hair loss is often a clue rather than a problem itself. And last week we talked about stress and why the goal isn't to eliminate stress, but to build resilience and to give your bodies an opportunity to recover. Today we're bringing all of those conversations together because if there's one symptom that seems to connect almost everything we talk about, it's sleep. And more specifically, waking up in the middle of the night and wondering why you can't get back to sleep. I can't tell you how many women have said something like this. I fall asleep just fine, but every night I'm awake at three o'clock in the morning. Or once I'm awake, my mind won't shut off. Sometimes it's exactly three, sometimes it's two, sometimes it's four. The exact time isn't nearly as important as the pattern. The question isn't why did I wake up? Because waking up briefly during the night is actually normal. The real question is, why can't I get back to sleep? That's a very different conversation. And while social media often gives us one similar answer, maybe it's cortisol, maybe it's blood sugar, maybe it's hormones, real life is usually more complex than that. We're going to walk through the most common reasons sleep changes during midlife, why so many systems can influence your sleep, and how understanding those systems can help you ask better questions about your own health. Because just like every other episode in this series, sleep isn't simply about sleep. It's another window into how your body is functioning as a whole.

Why Waking Up Is Normal

Speaker 4:23

Let's start with something that surprises almost everyone. Waking up during the night is actually normal. Yes, you heard me correctly. The problem isn't usually waking up. The problem is when your brain and body struggle to settle back down into sleep. So let's talk about why that happens. Let's start with the question: have you ever said I shouldn't be waking up at all during the night? If so, you're certainly not alone. But here's something that surprises many people. Most of us wake up several times every night. In fact, brief awakenings are a completely normal part of sleep. The difference is that most of the time we don't remember them. Our brain briefly becomes more alert as we transition between different sleep stages. We may roll over, adjust the blanket, change the position, and then drift back to sleep without ever realizing we woke up. That's healthy sleep. The problem isn't waking up. The problem is when your brain becomes alert enough that you can't settle back down into sleep. That's when you look at the clock. That's when you start doing the math. If I fall asleep right now, I'll still get four hours of sleep. Five minutes later, you're still awake. Then your mind starts working. You remember tomorrow's meeting, that bill you forgot to pay, your daughter's appointment, something you said yesterday that you wish you had not said. And before long, you're wide awake. You're thinking, planning, problem solving, worrying. And the more your mind begins to be engaged, the harder it becomes to fall asleep. Because sleep isn't something we force, it is something we allow. Your brain has to feel safe enough to go to sleep. When your mind shifts into problem-solving mode, your body receives a very different message. It begins preparing for action instead of rest. And that's why simply telling yourself, go back to sleep almost never works. So, what causes your brain to become fully alert instead of simply rolling over and drifting back to sleep? The answer isn't always the same. For some women, changing hormone levels are a major contributor. For others, it's blood sugar, stress, medications, pain, or even sleep habits may have played a

Hormones That Change Midlife Sleep

Speaker 6:49

role. Let's start with one of the biggest changes that occurs during midlife, hormones. One of the biggest changes that happens during perimenopause and menopause is that sleep becomes less predictable. Maybe you used to sleep through the night without thinking twice about it. Now you wake up more easily. A noise that never used to bother you now suddenly wakes you. You feel warmer than you used to. Your mind seems to be switched on in the middle of the night. If this sounds familiar, you're not imagining it. Hormonal changes can absolutely influence the quality of your sleep. Let's start with estrogen. Most people think of estrogen as a reproductive hormone, but it does so much more than regulate menstrual cycles. Estrogen interacts with the brain, it influences body temperature, it affects mood, it supports healthy blood vessels, and it even plays a role in some of the neurotransmitters involved in sleep. As estrogen begins to fluctuate during perimenopause and eventually decline after menopause, many women notice that sleep simply doesn't feel restorative. And then there's progesterone. Progesterone naturally has a calming effect on the brain. Some people even describe it as nature's calming hormone. As progesterone declines during perimenopause, many women notice they're more likely to feel restless, more sensitive to stress, and more easily awaken during the night. Now I want to be careful here. This doesn't mean every sleep problem is caused by hormones, and it certainly doesn't mean every woman needs hormone therapy. It simply means that changing hormone levels are one of the pieces of the puzzle. Then there's another factor that many women recognize immediately: hot flashes or night sweats. Sometimes women don't even realize they're having them. Then they wake up, they throw the blankets off, and a few minutes later they're cold, pull the blankets back up, and only later realize they were probably awakened by a change in body temperature. Even a brief increase in body temperature can interrupt the normal progression through the sleep stages. And once you're awake, your brain has an opportunity to start thinking. That's when the planning begins, the worrying and the mental to-do list. And suddenly what started as a normal awakening becomes 30, 60 minutes of lying in bed staring at the ceiling. So yes, hormones absolutely matter, but they aren't acting alone. They're interacting with your nervous system, your stress response, your environment, and your habits, and all of the other systems we've been talking about through this series. That's why two women can have the exact same hormone levels and experience sleep in very different ways. Our bodies are wonderfully complex. And that's why understanding the whole picture is so much more important and helpful than looking for one simple answer. Hormones are one important piece of the puzzle, but they're not the only reason women wake up in the middle of the night. Another

Blood Sugar And Night Wakings

Speaker 10:04

factor that's getting a lot of tension recently is blood sugar. Can low blood sugar wake you up at three in the morning? Sometimes, let's talk about what we know and what we don't know. Another explanation you may have heard is if you're waking up at 3 o'clock in the morning, it's because your blood sugar is crashing. Like many things we've talked about in this podcast, the answer is maybe. For some people, blood sugar fluctuations may contribute to nighttime awakening, but it is not the explanation for everyone. Here's why. Your brain depends on a steady supply of glucose for function. During the night, while you're sleeping, your body works very hard to keep your blood sugar within healthy range. It's constantly making small adjustments without you ever even knowing. If the blood sugar begins to fall, your body has several ways of responding. One of those ways is by releasing hormones that help bring blood sugar back up into the normal range. For some people, particularly those with diabetes, certain medications, or other metabolic conditions, those changes can sometimes interrupt sleep. For others, large swings in blood sugar related to eating patterns may contribute to restless sleep. For many healthy adults, the body manages these overnight changes remarkably well. And that's why I want to be cautious about blaming every middle of the night awakening on blood sugar. The evidence simply doesn't support such a broad conclusion. Instead, I encourage women to think about the bigger picture. Are you waking because you're drenched in sweat from a hot flash or anxious? Is pain awakening you up? Do you snore loudly or stop breathing during the sleep? Are you drinking alcohol close to bedtime? Have you been under an unusual amount of stress? Are you taking medication that could be affecting your sleep? These questions often provide more helpful clues than assuming there's one universal cause.

Sleep As An Orchestra

Speaker 12:11

And that's exactly how we approach it in clinical practice. We don't begin with one answer. We begin with curiosity. Sometimes I tell patients that sleep is like an orchestra. Imagine an orchestra getting ready for a performance, the strings, the brass, the percussion, and the woodwinds. Each section has its important role. If one violin is slightly out of tune, the music may still sound beautiful, but if several sections begin drifting out of rhythm, the entire performance changes. Sleep works much the same way. Hormones, stress, and temperature regulation, blood sugar, pain, breathing, light exposure, medications, nutrition, movement, and mental health, they all play an instrumental role in the orchestra. Sometimes one section is louder than another, sometimes solar or slightly out of tune at the same time. Our job isn't to blame one instrument. Our job is to listen to the entire orchestra. That's why I rarely look for one magic explanation. I'm listening for the patterns. And speaking of patterns, there's one more piece of this conversation that I think often gets overlooked.

Daytime Habits That Set Sleep

Speaker 13:27

It's not just what's happening during the night. It's everything that's happening during the day that prepares your body for sleep. Let's talk about why your daytime habits matter just as much as your bedtime routine. When most people struggle with sleep, they start looking at what they're doing right before bedtime. Should I stop looking at my phone? Should I drink chamomile tea? Should I take magnesium? Should I buy a weighted blanket? Should I buy dark curtains? And while all those things can certainly have a place, I think we sometimes put too much emphasis on the last 30 minutes of the day. The truth is your body has been preparing for sleep since the moment you woke up that morning. Sleep isn't something that begins at bedtime. It's the result of everything your brain and body have experienced throughout the day. Think about what we've talked about over the last few episodes. Stress, hormones, nutrition, movement, light exposure, they're all influencing your body's internal clock. One of the most important signals your brain receives every morning is light. When sunlight reaches your eyes shortly after waking, it helps reinforce your circadian rhythm, your body's internal 24-hour clock. That signal helps your brain understand it's daytime. Stay alert now so you're ready for sleep later tonight. As the day progresses, another hormone called melatonin gradually begins to rise, preparing your body for sleep. The process works best when your body has clear signals about day and night, but modern life often blurs those signals. Many of us spend many of the days indoors. We're exposed to bright screens late into the evening. We answer emails in bed. We watch television until we fall asleep. Our brains don't always receive the strong environmental cues they were designed to expect. Now I want to be realistic. I'm not suggesting that you have to live a perfect life. You don't need to throw away your phone or sit outside for hours every morning. Small, consistent habits often matter more than a dramatic set of changes. Getting outside for a morning walk, moving your body regularly, eating meals consistently throughout the day, limiting alcohol close to bedtime if you've noticed it disrupts your sleep. Creating a bedtime routine that helps your brain recognize the day is ending. Those simple habits support the natural rhythm your body already knows how to follow. And perhaps one of the most important habits of all, giving yourself permission to unwind before your head hits the pillow. For many women, bedtime becomes the first quiet moment of the entire day. The house is finally still, the phone stops ringing, the distractions disappear, and suddenly your brain starts processing everything it didn't have time to think about earlier in the day. If you've ever climbed into bed physically exhausted but mentally wide awake, you're not alone. That's not a sign that you've failed. It's a sign that your brain finally has enough quiet to catch up. Sometimes creating a few minutes of intentional quiet before bedtime, whether that's reading, journaling, praying, gentle stretch, or simply sitting without a screen can help your mind begin that process before your head reaches the pillow. Not because it's a magic cure, but because giving your nervous system an opportunity to begin shifting towards rest. So how do we pull all of this

3 A.M. Is A Symptom

Speaker 17:17

together? If there's one thing I hope you take away from today's episode, it's this waking up at 3 o'clock in the morning isn't a diagnosis. It's a symptom. And like every symptom we've talked about over the past several weeks, it's your body's way of inviting you to become curious, not fearful, curious. Because sleep is influenced by so many different systems working together. Your hormones, your stress response, your nervous system, your metabolic system, your environment, your daily habits, and your overall health. That's why I encourage women to be cautious of anyone who promises one simple explanation or one simple solution. Health is rarely that straightforward. As we've talked about throughout this series, your body isn't made up of isolated parts. It is incredibly interconnected. Your thyroid influences your metabolism. Your metabolism influences your energy. Stress influences your sleep, and sleep influences your hormones. Your hormones influence your mood. Every system is communicating with the other. And that's why understanding your health isn't about chasing symptoms. It's about learning to see the whole picture. I know that it can feel overwhelming at times, but I actually find it incredibly hopeful because it reminds us that there are often multiple pieces where we can begin supporting our health. Sometimes improving sleep starts with managing stress. Sometimes it's treating hot flashes. Sometimes it's addressing your sleep apnea. Other times it's reviewing your medications, maybe improving your sleep habits. And then lastly, identifying underlying medical conditions that deserve attention. The important thing is that you don't have to figure it out all alone. Partner with a healthcare provider who listens to your story, looks at the whole picture, and helps you understand what your body may be trying to tell

If you found today's episode helpful, I'd love for you to share it with a friend who's been wondering why she keeps waking up in the middle of the night or leave a review wherever you listen to this podcast. It helps more women discover these conversations and builds a community of women who are learning to better understand their bodies. Over the past month, we've talked about your thyroid, hair loss, chronic stress, and sleep. At a glance, those may seem like completely different topics, but I hope you've noticed they all have something in common. They're reminders that our bodies are constantly communicating with us. The more we understand those messages, the more confident we become in asking questions, having conversations with our healthcare providers, and making informed decisions about our health. That's what this podcast is all about, helping you understand your body one conversation at a time.
