What to Do When You Can’t Turn Off Your Brain at Night

Can you relate to this? You’ve done everything right. The lights are off, the phone is face-down, and you’re finally in bed at a reasonable hour. And then your brain starts talking. Did I respond to that email? What if I said the wrong thing at that meeting? I need to schedule that appointment. What are we doing for the holidays? Before long, thirty minutes passed. Then an hour. The harder you try to sleep, the more awake you feel.

If this sounds familiar, you’re not alone. NSF’s Two Views of the Night report with support from Tempur-Pedic, showed 61% of American adults report frequent difficulty calming their minds at bedtime. That makes racing thoughts the single most common sleep disruptor in the country. It outranks noise, temperature, physical pain, and even a partner’s snoring. Even though nearly half of Americans (47%) say racing thoughts at bedtime have a significant negative impact on their sleep, they don’t affect everyone equally. Women are significantly more likely than men to report difficulty calming their minds before sleep. 

Why the Brain Won’t Quiet Down

Sleep doesn’t happen like a light switch. Mostly, it’s a gradual process that needs your nervous system to slow down. Your heart rate slows, body temperature drops, and brain activity eases from active to calm. For that transition to happen, the brain needs to release its grip on the day’s events.

Stress is bad for sleep.  Actually, the primary stress hormone is cortisol, and it is supposed to be normally low at night, increasing in the early morning to help you wake up. When you’re anxious or overwhelmed, your body maintains elevated levels of cortisol, which is not a great recipe for sleep.  So, one of the first things you can start to practice every day to help your body’s natural tendency is a wind down routine.  This routine could use shared concepts or be unique to you. It’s one of the nighttime elements NSF says is important to being your Best Slept Self®.

Build a Real Wind-Down Routine

Your brain responds to cues. A consistent wind-down routine starting 30 to 60 minutes before your target bedtime teaches the nervous system that sleep is coming and it’s safe to start downshifting. Effective wind-down routines typically include dimming the lights, reducing screen exposure, lowering the room temperature if possible, and switching to low-stimulation activities like reading, light stretching, or listening to calm music. The specific activities matter less than the consistency, doing the same sequence each night builds a powerful sleep association over time.

More Evidence-Based Tips

• Try Controlled Breathing: When anxious thoughts accelerate, your breathing often does too and slowing it down can interrupt the cycle. Slow-paced breathing can calm your body.
• Attempt Progressive Muscle Relaxation: Tensing and releasing muscle groups from your feet upward has a strong evidence base for reducing both sleep onset time and nighttime wakefulness.
• Get Out of Bed If You’re Stuck: This one feels counterintuitive, but if you’ve been lying awake for more than 20 minutes, get up. Go to another room, do something calm and non-stimulating, and return to bed only when you feel sleepy.

The Bottom Line

If racing thoughts at bedtime are a nightly occurrence, it’s worth asking what’s driving them during the day. A mind that won’t quiet down at bedtime isn’t uncommon, it’s one of the most widespread sleep challenges in America, affecting nearly three in five adults. Stress management strategies including regular physical activity, time outdoors, social connection, and therapy where appropriate, can reduce the overall cortisol burden your brain is carrying into the evening. Small changes, practiced consistently, can make a meaningful difference and help you get on your way to being your Best Slept Self^®.
