Why We Wake Up At Night and How Mindfulness Helps Us Sleep Again

There are lots of reasons why wake up at night and might be losing sleep. Angela Stubbs explains what’s happening, and how mindfulness can help us ease back into better rest.

You’re awake, and the time on your nightstand shows 3:33 a.m. There’s no reason to be awake, but your mind has other ideas. Some nights it could be an overactive mind; other times, you’re fighting a hot flash or the urge to scroll on your phone, hoping to fall back asleep.

Regardless of what’s calling to you in the middle of the night, the message you really need to hear: You’re not alone.

Nearly 18% of U.S. adults report trouble staying asleep, and 30–50% experience insomnia symptoms, including difficulty falling or staying asleep. And yet, our initial response to waking in the middle of the night tends to lean toward frustration or anger rather than curiosity.

Dr. Jessica Shepherd asks her readers to be curious about the patterns and symptoms we experience around wakefulness instead of moving towards “fixing” our sleep problem.

What would happen if we chose to investigate our feelings around wakefulness with self-compassion and mindfulness, instead of pushing against our own discomfort with what’s unwanted? Understanding more about why we wake up at night can help.

The Nervous System and Sleep Disruption

When did 3 a.m. become the new wake-up call?  If you’ve slept soundly for most of your life, only to be suddenly confronted with a nightly routine that involves struggling to get back to sleep, know you’re in good company. These “wakeups” happen across ages, genders, and all life stages. Some of us (ahhem, menopause ladies, we see you) begin having some of these issues as a result of hormone shifts (we’ll get into that later).

What you need to know is that waking in the night is not a personal failure.  Oftentimes, your nervous system responds to cues your body sends, both internal and external. Here are a few reasons why we wake up at night, and why your sleep may be feeling more fragmented:

  • Hyperarousal: Stress hormones like cortisol and adrenaline can trigger micro-awakenings. Even while asleep, your brain is scanning for potential threats.
  • Racing or overloaded mind: Daytime to-do lists, worries, or plans can linger into the night, keeping your brain alert.
  • Environmental triggers: Neighborhood noise, light, temperature swings, or even screens can subtly wake the brain.
  • Aging sleep architecture: As we age, our sleep naturally becomes lighter and more fragmented.
  • Hormonal shifts: As I mentioned above, if you’re in perimenopause or menopause, changes in estrogen, testosterone, and progesterone can significantly affect your sleep cycles. They can disrupt sleep when you’re experiencing hormone imbalances. Still, these shifts are a small part of the overall picture when we consider why many people experience nighttime wakefulness.

Why starting with curiosity helps

OB-GYN and author of Generation M, Dr. Jessica Shepherd, asks her readers to be curious about the patterns and symptoms we experience around wakefulness instead of moving towards “fixing” our sleep problem. Here are four questions she poses to help guide reflection: 

  • Is this wake-up due to hot flashes or night sweats?
  • Am I waking repeatedly or having trouble breathing?
  • Is my mind racing too much to fall asleep or fall back asleep?
  • Do I need to use the bathroom frequently at night?

While Dr. Shepherd is a go-to source for menopausal struggles and solutions, these questions can be used to assess your symptoms, regardless of your age. Typically, mid-morning wakeup calls fall into one of these four categories:  mental overactivity, changes in body or room temperature, repeated environmental disruptions, or physical cues. When we understand the causes and conditions for our experience, we can cultivate a mindful response.

Why Are My Thoughts Awake at 3 a.m.?

The main culprit for middle-of-the-night wakefulness can vary from person to person. No matter what time you’re waking up, if it’s before your alarm clock goes off, it’s likely to feel unsettling.

For those of you in perimenopause or menopause, the shift of our hormones (feeling hot flashes/night sweats) can make us feel very stressed out. As our stress levels rise, so do our cortisol levels. Typically, this stress hormone rises around 3 a.m. to prepare us for waking, but if our stress levels are too high, it can shift that baseline and cause us to wake up earlier than usual.

Mindfulness offers a different way to approach these interruptions. It nudges us first to accept what’s happening in the present moment, and then to gently turn towards curiosity and self-compassion.

For those of you who have surpassed that hurdle of menopause or generally have trouble falling asleep or staying asleep, this time of night can feel so much louder than usual. When we’re alone with our thoughts in the middle of the night, our fears can feel heightened. Sleep deprivation heightens amygdala reactivity, making even small anxieties feel intense. Mindfulness can help settle our nervous system by guiding us towards practical tools that help us eliminate spiraling narratives.

So, how can you shift your perspective when it comes to that mid-morning wake-up? Mindfulness offers a different way to approach these interruptions. 

We’ve all heard the phrase, What you resist, persists, and you likely know from experience that it doesn’t work to fight sleeplessness or try to force yourself to go back to sleep. 

Mindfulness nudges us first to accept what’s happening in the present moment, and then to gently turn towards curiosity and self-compassion. So perhaps the questions and phrases we could be engaging with might sound more like, “How can I offer myself compassion when sleeplessness makes itself known?” or, “What is this experience trying to show me?”

Look for clues in your daily routines

Sleep expert and author of Powerful Sleep, Shawna Robins, encourages people who have trouble navigating the “wide-awake” brain by taking a look at what they’re doing during the day.

She emphasizes laying the groundwork for a healthy routine (meals, exercise, self-care) that supports hormone balance and your nervous system. For Robins, that begins with stress management, proper nutrition, and some form of physical activity. When we do these things, sleeping, and specifically “falling asleep” or returning to sleep after that three o’clock wake-up, can get much easier. Robins says, “Healthy sleep starts during the daytime with healthier habits. It’s not just about what happens when you get into bed at night.”

Mindful Sleep Strategy

What does a mindfulness strategy look like for cultivating good sleep? Think about all the tools you’ve developed over the course of your mindfulness journey and start putting them to use.

Sleep supports the choices we make before bed.

That means journaling, sitting regularly, mindfully eating and noticing the times you’re eating. It can also involve checking in with your physical body (think body-scan meditation or breathwork), coupled with daytime routines (yoga/gym workout, exercises you can do throughout the day at work/your desk, etc.) that will help create a stable space for you to reset your energy and recalibrate your nervous system. Sleep supports the choices we make before bed.

If you find yourself up in the middle of the night and can’t get back to sleep, here are some different ways you can try to help yourself. 

  1.  30-Second Body Scan
    Redirect attention from racing thoughts to physical sensations, noticing each part of the body without judgment.
  2. Lengthened Exhale Breathing (4–6 breaths)
    Extending the exhale calms the parasympathetic nervous system, signaling the body that it is safe to rest.
  3. Thought Noting
    Label thoughts gently (“I’m worrying,” “I’m planning”) to create mental distance.
  4. Journaling
    Keep a notepad by the bed to externalize racing thoughts and reduce cognitive load.
  5. Gentle Somatic Grounding
    Release tension in the jaw, shoulders, or belly to help the body signal safety.

Nighttime wakefulness often coincides with vivid or emotionally charged dreams. Sansan Fibri, founder of the app Wakefully.io, describes dreams as “our subconscious screenplay, where hidden narratives sometimes replay on repeat.”

Wakefully is an AI-driven dream-analysis and journaling app that allows users to examine dream themes and emotions or reframe dreams with evidence-based techniques. For those who wake at night due to intense dreams or lingering emotional tension, incorporating tools like Wakefully alongside your mindfulness practice can help shift into a more reflective space, calming a reactive mind. With curiosity, gentle awareness, and practical tools, you can transform these moments into opportunities for connection with your body and mind.

When we approach sleep with mindfulness,  we can meet moments of wakefulness with curiosity instead of frustration, helping us meet them in the middle of the night with presence and ultimately a sense of well-being.
