Struggling to sleep after a traumatic experience is one of the most common and exhausting effects of trauma. Understanding why it happens can make it feel less frightening, and there are practical steps that can help.

What it is

Trauma can affect sleep in several ways. The nervous system may remain on high alert long after the danger has passed, making it hard to relax enough to fall asleep. Nightmares or vivid dreams related to the event are common, sometimes causing people to avoid sleep altogether out of fear of what they might dream. Waking suddenly, feeling on edge through the night, or sleeping much more or less than usual can all be part of a trauma response. Poor sleep, in turn, can make other trauma symptoms - like irritability, difficulty concentrating and low mood - feel worse, creating a difficult cycle.

Signs to notice

Difficulty falling asleep due to racing thoughts or a sense of unease
Frequent waking through the night, sometimes with a racing heart
Nightmares or distressing dreams connected to the traumatic event
Avoiding sleep or delaying bedtime out of fear of nightmares
Feeling exhausted despite spending long hours in bed
Increased irritability, anxiety or low mood that seems connected to poor sleep

What helps

Keep a consistent sleep and wake time, even on weekends, to help regulate your body's rhythm.
Create a calming wind-down routine before bed, avoiding screens, news and stimulating conversations in the hour beforehand.
Try grounding or breathing exercises if you wake feeling unsafe or panicked, rather than immediately reaching for your phone.
Keep your bedroom associated with rest, not with lying awake worrying - if you cannot sleep after twenty minutes, get up and do something calm before trying again.
Limit caffeine and alcohol, both of which can worsen sleep quality and trauma symptoms.
Be gentle with yourself about disrupted sleep. It is a common trauma response, not a personal failing.

When to reach out for help

Reach out to a professional if poor sleep has continued for several weeks, is affecting your ability to function during the day, or is accompanied by frequent nightmares, flashbacks or a fear of sleeping. Sleep difficulties connected to trauma often respond well to targeted professional support, so there is no need to simply endure them.
