Ever feel like your brain just won’t shut off at night? You’re not alone. From doomscrolling the news to juggling a hectic schedule, everyday stressors can lock your body into “fight-or-flight” mode—making it hard to relax, let alone sleep. The good news is that by understanding how your nervous system affects sleep, you can start making small changes that lead to big improvements—and making sure your spine is properly aligned while you rest can also play a key role in helping your body settle into deeper sleep.
Understanding the Nervous System’s Role in Sleep
Your nervous system has two main settings: fight-or-flight and rest-and-digest. When you’re in fight-or-flight mode (sympathetic nervous system), your body stays alert and on edge—ready to react to stress. This response is helpful in emergencies but keeps your heart rate high, muscles tense, and mind racing, making it difficult to fall asleep.
On the other hand, when your rest-and-digest mode (parasympathetic nervous system) takes over, your body slows down. Your heart rate drops, your breathing deepens, and your muscles relax, creating the perfect environment for deep, restorative sleep. Balancing these two systems is key to a healthy sleep cycle.
Chronic Stress: The Ultimate Sleep Blocker
Stress doesn’t just come from big life changes—it sneaks in through the small, daily habits we barely notice. Over time, even low-level stress can overstimulate your nervous system, making it harder for your body to switch off and settle into deep, restful sleep. When the stress response stays active too long, it leads to sleep disruption, poor recovery, and that drained feeling—even after a full night in bed.
Some of the most common triggers that can keep your nervous system stuck in fight-or-flight mode:
A jam-packed schedule without breaks
Racing from task to task without mindful pauses
Skipping meals or relying on caffeine to power through
Checking your phone right before bed
Reading stressful news headlines
Scrolling through social media late into the night
Even though these activities seem harmless, they overload your brain with stimulation, raise cortisol levels, and delay your ability to access deep, restful sleep.
How Prolonged Stress Disrupts Sleep
When stress hormones stay elevated for too long, they disrupt your body's ability to fully relax and repair overnight. Chronic activation of the fight-or-flight response increases nighttime wakefulness, shortens the amount of time you spend in deep sleep, and leaves you feeling groggy and unrefreshed in the morning. Habits like binge-watching TV late into the night or answering emails right before bed might feel productive or comforting in the moment, but they keep your nervous system stuck in "go mode" when it should be winding down for restful sleep.
Spinal Alignment and Nervous System Regulation
Your spine is more than just a structural support—it’s the protective pathway for your spinal cord, which carries vital messages between your brain and body. When your spine is properly aligned, your nervous system can function at its best, helping your body shift smoothly into rest-and-repair mode. But when misalignments occur, they can disrupt nerve communication, keeping your system stuck in a low-level fight-or-flight state, making it much harder to fully relax at night.
Common posture-related habits that may affect sleep:
Slouching during the day, leading to upper back and neck tension
Forward head posture from screen time
Sleeping in awkward positions that misalign the spine
Signs You’re Stuck in Fight or Flight at Night
When your nervous system stays stuck in fight-or-flight mode, your body struggles to fully wind down—even after a busy day. Sleep may feel frustratingly out of reach, and instead of waking up refreshed, you might start the day already feeling depleted. Recognizing the signs of nervous system imbalance is the first step toward getting the help you need.
Watch for these common symptoms:
Racing thoughts before bed
Clenching your jaw or grinding your teeth
Feeling “tired but wired”
Tossing and turning throughout the night
Waking up multiple times or too early
A racing heart or shallow breathing in bed
Tension headaches or tight muscles overnight
Waking up feeling anxious or unsettled
If several of these sound familiar, your nervous system could be stuck in a stress loop that’s blocking your ability to access deep, restful sleep. The good news? There are natural ways to help shift your body back into a calm, restorative state—and chiropractic care can play an important role in making that happen.
