Why Can't I Sleep After Trauma? Working Through Insomnia and Nervous System Activation

Written by Roland Bal

Not being able to sleep, fall asleep, stay asleep, or have a restful sleep are very common symptoms when dealing with trauma. Your fight-flight mechanism and accompanying hormones are likely to be on overdrive; fatiguing your adrenals and affecting your overall health.

Furthermore, when you suffer, you naturally attempt to get away from it and try to overcome it.

Your Fight-Flight Mechanism Is Rallied Up

When you are triggered and activated, your fight-flight mechanism is rallied up. Your adrenaline gets going and it might take hours or even days before you are able to regulate yourself and come back down from the activation.

When you suffer, you naturally attempt to get away from it and try to overcome it.

The trouble is, when you are dealing with complex trauma, that you seem to be constantly going through cycles of high activation and shutdown, which wears you down.

In time, your hormonal balance and sleep cycle will be deranged adding insult to injury.

Insomnia, Being Triggered, and Lack of Energy

When you don't sleep well, you become emotionally more unstable, making it easier to get triggered and activated again.

Lack of sleep, being triggered, and having to deal with a lack of energy can then become a vicious cycle.

You need sleep to regenerate and balance your nervous system, immune system, and hormonal system.

Why Sleep Becomes the Battleground

During the day, there is structure. Work, tasks, movement — all of it keeps you occupied. But at night, when the house goes quiet and you lie down, the unprocessed activation rises. There is nowhere to put it. Your body does what it knows: it stays alert.

For many people carrying unresolved trauma, bedtime becomes a trigger in itself. The stillness, the darkness, the vulnerability of closing your eyes — these are conditions your nervous system may have learned to associate with danger. Not because of anything rational, but because of what your body went through.

Some people deal with hyperarousal at night — racing thoughts, a tight chest, a sudden jolt of alertness the moment they start to drift off. Others swing the other way and use sleep as dissociation — crashing out of exhaustion but never actually resting. Both are survival responses. Neither is real sleep.

How Insomnia Relates to Trauma

To address insomnia related to trauma, you also need to address the trauma itself — if that is what caused your lack of sleep or disturbed sleep in the first place. You cannot focus on one part only.

You can help yourself with sleep aides and techniques but you will only be successful to a degree.

What you need is to put two and two together and address both your sleep issues and your nervous system activation at the same time to see improvement and results.

The Deeper Layers Underneath Sleeplessness

What I have found over 25 years of working with people is that insomnia related to trauma is rarely just about sleep. There are layers underneath it.

There is the adrenal and brain stem activation that keeps your body wired even when you are depleted. There is the conflict that arises from trying to overcome sleep. There are nightmares that replay unresolved activation — the wanting to relax or pushing for falling asleep becomes an obstacle in itself. There is the way some people use sleep as a disconnection from feeling too much, which is not rest but avoidance.

And then there is the pleasing response — the chronic pattern of putting others first, over-adapting, and running on empty — which feeds directly into burnout and sleep disruption. When your energy is perpetually invested in managing other people's needs and emotions, there is nothing left for your own system to settle with at night.

These are the layers that need to be addressed. Not just the surface symptom of not sleeping, but the why underneath it. When you work with the body — through somatic approaches — you begin to unravel these patterns at the level where they actually live: your nervous system.

What You Can Do About It

You need to address both the sleep issue and the underlying nervous system activation. Calming your nervous system for sleep is not about forcing relaxation. It is about learning to be with what is present — the restlessness, the tension, the emotion — without drowning in it and without dissociating from it.

When you start with where you are rather than where you want to be, it creates a different relationship with sleep. Somatic meditation works at this level — not by telling you to relax, but by helping you meet the activation and work through it gradually.

This takes time. It takes patience. But the nervous system can learn. It can be retrained.
