Panic Attacks at Night: Why You Wake Up Panicking

Updated 26 October 2026

What is a nocturnal panic attack?

It's a panic attack that starts while you're asleep. Nocturnal panic attacks are sudden episodes of intense fear that typically occur during non-REM sleep, with the same symptoms as daytime attacks: a pounding heart, sweating, nausea, and changes in your breathing². They tend to happen during brief awakenings as you move between light and deep sleep, and they're more common in the first half of the night².

Researchers describe them as a non-REM sleep event, distinct from nightmares, sleep terrors, and sleep apnea¹. In other words, you're not panicking because of a dream. The panic is what wakes you. If panic tends to start while you're still awake and winding down, that's a related pattern: see panic attacks while relaxing.

How common are night-time panic attacks?

More common than most people expect. In a review of the research, 44 to 71% of people with panic disorder reported having had at least one nocturnal panic attack¹. For most of them, night attacks happen alongside daytime ones. It's rare for someone to have mainly night-time attacks².

Was it a panic attack, a nightmare, or a night terror?

They can feel similar in the moment, but they're different events:

• Nocturnal panic attack: you wake up fully, with the fear and body symptoms already there, and you remember it afterwards².
• Nightmare: you wake from a frightening dream. Researchers separate these dream-induced awakenings from nocturnal panic¹.
• Night terror: there's usually no memory of it the next morning, and the sleeper may flail or even jump out of bed, which isn't usually seen with a nocturnal panic attack².
• Sleep apnea: repeated drops in breathing during sleep cause brief awakenings². If you suspect this, a doctor can arrange a sleep test.

What should you do when you wake up panicking?

Stay where you are and slow your breathing

The NHS advice for any panic attack applies at night too: stay where you are if you can, breathe slowly and deeply, and remind yourself that the attack will pass³. You don't need to get up to do this.

Remind yourself it isn't dangerous

Waking into panic in the dark can feel like an emergency. Panic attacks themselves are not life-threatening⁴, and nocturnal attacks usually become most intense within a few minutes². The worst part tends to come early and then ease.

Ground yourself in the room

The 5-4-3-2-1 technique works in the dark if you lean on the senses you can use: the sounds around you, the feel of the sheets, the temperature of the air, the weight of the blanket.

If you use your phone, keep it dim and brief

The NHS advises against using devices like smartphones right before bed, because the light makes you more awake⁵. If a phone helps you through the attack, turn the brightness right down and use it for the exercise, not for scrolling afterwards. An app that works offline and needs no login means there's nothing to set up at 3am.

How do you get back to sleep afterwards?

Don't force it. The NHS guidance on sleep is to only go to bed when you're sleepy and not to sleep in after a bad night⁵, so if you're wide awake, it's fine to sit somewhere calm and dim until sleepiness comes back. Keeping your normal wake-up time the next morning helps your sleep settle again.

If you often wake in the early hours without any panic, that's a separate pattern. Read why you might wake up at 3am.

Can night-time panic attacks make you afraid to sleep?

They can. Because you remember nocturnal attacks, they may lead to a fear of sleep, and when they keep happening some people become afraid to go to bed at all². That's a good reason to get support rather than wait for it to pass on its own. Treatment for panic disorder, including cognitive behavioural therapy, covers night-time attacks too¹, and in England you can refer yourself to a talking therapies service³.
