Why Trauma Keeps Your Brain Awake at Night
Episode Overview
- Trauma can keep the brain locked in survival mode, leaving you tired but unable to switch off at night.
- When the brain believes the world is unsafe, it keeps releasing stress hormones, even during sleep.
- Instead of entering deep, restorative sleep, the brain continues to scan for danger and keeps the body on high alert.
- Sleep routines often fail because the core problem is a nervous system that doesn’t feel safe, rather than simple insomnia.
- Real change starts when the nervous system begins to feel safe, allowing the brain to reduce its alertness and restore a healthier sleep cycle.
“Your brain isn't working against you. It is simply trying to protect you. But it has not learned to find the off switch.”
Ever wondered why your brain seems to wake up the moment your head hits the pillow? This short but punchy episode from The Trauma Recovery School looks at how unresolved trauma can leave the nervous system stuck in survival mode, wrecking any chance of a good night’s sleep. Speaking directly to anyone who feels exhausted yet wired, award-winning trauma recovery therapist Bonita Ackerman du Preez explains how the brain can misread the world as permanently unsafe.
When that happens, the body keeps pumping out stress hormones, even at night. Instead of sinking into deep, restorative sleep, your brain stays on guard duty, constantly scanning for danger. She describes the classic pattern many people know too well: **"Have you ever felt completely exhausted but the moment your head hits the pillow...
your brain suddenly wakes up and it absolutely refuses to switch off?"** Restlessness, endless thinking, wandering through the night and waking up unrefreshed are all framed as survival responses, not personal failures. A key message is that your brain is *trying* to protect you. Bonita repeatedly stresses that, "your brain isn't working against you... it is simply trying to protect you," even if that protection now backfires and sabotages sleep.
This also explains why standard sleep routines often fall flat; if the nervous system doesn’t feel safe, the body simply won’t fully relax. Bonita briefly mentions her trauma recovery method and TRM blueprint, which focus on helping the body calm down first so the brain can finally "find the off switch" and reset the sleep cycle.
If you’re stuck in that tired-but-wired loop, this episode offers a clear, compassionate explanation of what might be going on inside your body and mind. Could reframing your "insomnia" as a safety issue be the first step towards better rest?
