Nocturnal Panic Attacks: Why You Wake Up Terrified at Night
Waking suddenly with a pounding heart, shortness of breath and a sense of dread can be frightening, especially when there seems to be no reason. These episodes are called nocturnal panic attacks. They are distressing but they are not dangerous in themselves, and they can be treated.

What is a nocturnal panic attack?
A nocturnal panic attack is a panic attack that wakes you from sleep. Symptoms are the same as daytime panic and can include a racing heart, sweating, trembling, breathlessness, chest tightness, dizziness and a strong fear that something terrible is happening. They usually peak within minutes and then fade.
How it differs from nightmares and night terrors
A nightmare is a frightening dream that you can usually remember. In a nocturnal panic attack, people typically wake in a state of panic without a story or dream attached. Night terrors are different again: they tend to happen in children, and the person often does not fully wake or remember the episode.
Why do they happen?
Researchers are still learning about nocturnal panic. It appears to be more common in people who also experience panic attacks during the day, and stress, anxiety and sensitivity to bodily sensations can all play a part. Sleep itself is not a threat, but waking in a state of alarm can make people afraid of going to sleep, which creates a cycle of dread, poor sleep and further anxiety.
Other causes to rule out
Waking in a panic can sometimes have physical causes, such as sleep apnoea, acid reflux, heart rhythm problems or the effects of caffeine, alcohol or medication. If you are experiencing episodes at night, speak to your GP so that medical causes can be checked. If you have chest pain or think you are having a medical emergency, call 999.
What to do in the moment
These steps can help an episode pass:
- Remind yourself that this is a panic attack, that it will peak and pass, and that the sensations, though unpleasant, are not harmful
- Breathe out slowly, making the out-breath longer than the in-breath
- Sit up, put your feet on the floor and notice what you can see, hear and feel
- Avoid reaching for your phone to check symptoms, which tends to raise alarm
- Once the episode has eased, return to a calm, dim environment
What helps in the long term
Cognitive behavioural therapy for panic helps people understand the cycle of fear of sensations, and gradually reduces the power of those sensations through guided exposure. Reducing caffeine and alcohol, keeping regular sleep times and managing daytime stress can also help. Therapy can address the fear of sleep that often develops after repeated episodes.
