Racing thoughts at night: How to achieve a calm and restful mind

Racing thoughts at night—especially when you wake up in the middle of the night—are mainly caused by all the unprocessed stress, anxiety, and overstimulation you’ve been holding in from your day.

‍

My mind used to ping-pong between endless “what-ifs” and “if-onlys” at night. That restlessness from racing thoughts at night is what led me to meditation in the first place. Over time, I learned to form a sacred pact between the chaos of my thoughts and the deep calm beneath them.

‍

Now, if I jolt awake at 3 a.m. with my heart pounding and my mind replaying every failure or missed item on my to-do list, I stop fighting it. Because racing thoughts at night aren’t enemies. They’re unspoken prayers and unmet needs, waiting for acknowledgment.

What causes racing thoughts at night? 

Unfinished business 

‍

When you’re busy or distracted during the day, your nervous system is in go, go, go mode, but at night in the stillness, your brain can finally start sorting through your unexpressed desires, emotions, and worries, as well as any unmade decisions or unforgiven wounds you’ve been holding inside. Basically, whatever’s still emotionally charged that you’ve avoided by being “too busy” to process, will finally be unveiled. 

‍

So, reframe your racing thoughts at night as part of the de-stressing and release process. These thoughts can’t stay locked inside you forever, so if you don’t have a designated time in your life to sort through them, they’ll keep leaking out in the stillness of the night. 

‍

If your thoughts bring up dread, anxiety, or sadness, recognize them for what they are—the ache of an unlived life. Don't silence them. They aren’t the problem. They’re the messengers.

Cortisol and stress hormone release

‍

If you wake up between 2 and 4 a.m. with racing thoughts, it could be a cortisol spike. This survival mechanism once helped our ancestors stay alert against nighttime predators. But today, it’s more likely triggered by lingering stress, whether from unsent emails, unpaid bills, unresolved emotions, poor blood sugar balance, or an overstimulating evening of screens, caffeine, or intense conversations.

Blood sugar drops

‍

If you often feel wired but tired, you could have low blood sugar. This can happen if you eat dinner too early or have too much sugar or carbs without enough protein or fat. This can trigger an adrenaline rush that wakes you up. Next time this happens, try a small spoonful of almond butter or a few nuts to stabilize your blood sugar without spiking it. 

How to calm racing thoughts at night

Do a wind-down ritual

About one to two hours before bed, dim the lights and put away social media, email, or news. Pick up a healthy wind-down routine instead. Remember your brain is wired for survival (thanks ancestors!). So, without a proper wind-down, your brain will work overtime at night, sorting through the day’s unresolved emotions and lingering stressors—often triggering racing thoughts at night.

Brain dump before bed

‍

As part of your nighttime ritual, try journaling or voice-memoing your worries so they don’t replay on a loop. Keep a notebook by your bed and, each night, ask yourself: “What have I avoided feeling today?” Then, write just one sentence. Example: “I resented my boss, but I swallowed it.”

For extra release, crumple up the paper, throw it out, or even burn it as a symbolic way to let it go.

Regulate your nervous system

‍

Ever notice that the harder you try to sleep, the more your body resists it? That’s because the little bit of effort you use to fight your mind is actually causing more dysregulation in your nervous system. If you start doing something calming but not stimulating, you’ll help your body rest and you’ll fall asleep more easily. Such as: 

• Progressive muscle relaxation (tense & release muscles).
• Extended exhaling (inhale for 4, exhale for 6).
• Humming or a gentle self-massage.
• Mentally scan your body from head to toe, saying “Thank you” to each part: Thank you, eyes, for seeing today. Thank you, legs, for carrying me. Thank you, heart, for beating. This shifts your brain and nervous system into a parasympathetic (rest) state.

Release excess cortisol

Don’t wait until the end of the night to start regulating your cortisol. During your days, start exposing yourself to sunlight and moving your body. Also, try doing breath practices like 4-7-8 breaths (inhale for 4, hold for 7, exhale for 8, repeat 4x). This floods your body with nitric oxide, which helps put the brakes on cortisol. 

You can also press a chilled washcloth to your face or forehead, or splash cold water on it for 15-30 seconds. This activates your mammalian dive reflex. It’s a biological response that shocks your vagus nerve, lowers your heart rate by 10-25%, and pulls you out of fight-or-flight so you can feel more calm. Research indicates that with repeated exposure you can cut down your cortisol by about 30% or more in seconds with this method. Again, it works best if you do this alongside 4-7-8 or extended exhaling breath techniques. 

Interrupt your thinking 

‍

If you’re stuck in an anxious mental loop despite trying the above methods, try one of these three categories of strategies:

1. Re-direct your attention techniques

These help shift your focus away from anxious spirals and give your mind a neutral task:

• Count backward from 100. This math-based task forces your brain to focus on logic instead of anxiety.
• Imagine yourself in a peaceful place. Picture floating on water, sitting by a fire, or watching waves roll in.
• Repeat a calming phrase. Try “In this moment, I am safe and have everything I need.”

2. Physical grounding techniques 

These help anchor you in your body so your mind doesn’t feel so detached or overactive:

• Press your palms firmly against a wall and push gently to create a feeling of stability.
• Clench a fist tightly for 10 seconds, then release. Repeat 3 times. This somatic reset tells your nervous system, “We’re safe. There are no threats here.”
• Lie down diagonally across your bed instead of the usual position. This subtle change can disrupt a thought loop.

3. Breath and sound-based techniques 

These use the vagus nerve and breathwork to calm the body:

• Hum the lowest note you can. This activates your vagus nerve, signaling relaxation.
• Try the 4-7-8 breath. Inhale for 4, hold for 7, exhale for 8. This slows your heart rate and reduces cortisol.
• Do extended exhaling. Inhale for 4, exhale for 6-8 to shift your nervous system into a rest state.

Reframe your wake-ups

Instead of forcing yourself back to sleep…perhaps just listen. Breathe. Observe. Maybe this moment is trying to show you something. What truth is demanding your attention?

In those moments, remember: racing thoughts at night are not enemies. They’re forgotten parts of you, asking to be seen.

The goal isn’t to silence them. It’s to listen. 

Maybe you journal. Maybe you simply observe.

Then, when it feels right, let yourself drift back down.
Trust that your body knows how to rest.

All you have to do is allow it.
