What to do if…
you wake up short of breath and can only breathe comfortably sitting up

Short answer

Treat this as urgent. Stay sitting upright and get same-day medical help — call 999 if you’re struggling to breathe (for example, gasping/choking or only able to speak in short phrases), you have chest pain, blue/grey lips/skin, confusion/drowsiness/dizziness, or you’re getting worse.

Do not do these things

  • Do not lie flat “to see if it passes” if sitting up is the only way you can breathe comfortably.
  • Do not try to drive yourself to A&E if you feel faint, very breathless, or your symptoms are worsening.
  • Do not take someone else’s inhaler, antibiotics, leftover steroids, or “water tablets”.
  • Do not ignore new breathlessness at rest, especially if it woke you from sleep.
  • Do not smoke or vape right now, and don’t drink alcohol “to calm down”.

What to do now

  1. Get into the safest breathing position. Sit upright on the edge of the bed or in a chair, feet on the floor. Support your arms on your thighs or a table. Loosen tight clothing.
  2. Check quickly for emergency red flags — and act immediately if any are present.
    Call 999 if you have any of these:
    • severe difficulty breathing (gasping, choking, or struggling to speak)
    • chest tightness/heaviness or pain (especially spreading to arm/back/neck/jaw)
    • lips, tongue, face or skin turning blue or grey (on brown or black skin, check lips, gums, tongue, palms/soles)
    • sudden confusion, you’re very drowsy, very dizzy, or you feel like you might pass out
    • a fast new swelling of face/lips/tongue, or a severe allergic reaction
  3. If you have a prescribed reliever inhaler (e.g., salbutamol), use it exactly as you’ve been told. If you have an asthma/COPD action plan, follow the “breathless” steps on it.
  4. If there are no 999 red flags but you are still short of breath at rest, get urgent same-day advice. Call NHS 111 and say:
    “I woke up short of breath and I can only breathe comfortably sitting up. It’s new/worse than usual.”
    If you already have a heart or lung condition, say that early in the call.
  5. Prepare for help to arrive (or for an urgent assessment).
    • Keep sitting up; avoid lying down again.
    • Gather your medications/inhalers, a list of conditions, and any recent readings (peak flow, oxygen sats, BP) if you have them.
    • If you live with someone, tell them what’s happening and ask them to stay nearby.
  6. If symptoms worsen at any point, upgrade to 999. A change from “uncomfortable” to “struggling” matters.

What can wait

  • You do not need to work out the cause right now (there are several possible causes, some serious).
  • You do not need to decide about tests, referrals, or long-term treatment today.
  • You do not need to message multiple people or search the internet for reassurance while you’re still breathless.

Important reassurance

Waking up breathless and needing to sit up is frightening, and it can make you feel panicky very quickly. You’re not “overreacting” by treating this as urgent — getting assessed promptly is the safest move.

Scope note

These are first steps to stabilise you and get you to the right level of care. Follow-up and prevention depend on what clinicians find.
