Can Insomnia Be Traumatic?

When we think about trauma, we often think of a single frightening event. Something sudden, life-changing, and overwhelming.

What we don't often consider is that, for many people, the experience of chronic insomnia itself can become traumatic.

I'm not talking here about trauma causing insomnia, although that certainly happens. I'm talking about the months or years of lying awake in the middle of the night, the panic at 3 a.m., the racing thoughts, the fear that you'll never sleep again, and the exhaustion of dragging yourself through another day wondering how much longer you can keep going.

Over the years, I've met many people whose relationship with sleep has become defined by fear. That's one of the reasons I believe it's so important to acknowledge how distressing chronic insomnia can be. Despite affecting every part of a person's life, insomnia is often minimised. People are told it's "only sleep" or that they simply need to relax. But anyone who has lived with chronic insomnia knows it rarely feels that simple.

When we look at the effects of trauma, there are some striking similarities. Trauma often leaves people hypervigilant, constantly scanning for signs of danger. People with insomnia frequently do something very similar. They monitor the time, analyse how tired they feel, watch their thoughts, and search for clues about whether tonight will be another bad night.

The brain also begins to remember previous sleepless nights and use them to predict the future. A difficult night before an important meeting, a holiday, or a family event can be enough for the mind to start anticipating disaster the next time a similar situation arises. Gradually, life begins to shrink as more and more situations become associated with the possibility of not sleeping.

This doesn't mean insomnia and trauma are the same thing. But it does help explain why bedtime can feel so frightening. If your brain has learned that nights are threatening, of course your body becomes alert. It is doing exactly what it has evolved to do. It is trying to protect you.

Understanding insomnia in this way changes how we approach recovery. Rather than trying to force sleep or battle fear, we may need to help the nervous system rediscover a sense of safety. This is one of the reasons I was drawn to Acceptance and Commitment Therapy. Not because it removes fear overnight, but because it helps people gradually change their relationship with it.

Recovery often isn't about fixing a broken sleep system. Sometimes it's about helping a frightened system learn that it is safe again.
