The best way to sleep when congested is usually to elevate your head and upper body and, if one side is more blocked, sleep with the congested side facing up so drainage is easier. Keeping the room a bit humid and using saline before bed can also help reduce nighttime blockage.

Best sleeping setup

  • Use 2–3 pillows or a wedge pillow so your head, neck, and upper chest are raised about 30–45 degrees.
  • If one nostril is worse, sleep on the opposite side so the blocked side is higher and can drain better.
  • Avoid lying completely flat, since that can make mucus pool and worsen pressure.

What helps before bed

  • Try a saline spray or rinse to clear mucus gently.
  • Run a humidifier if the air is dry, especially at night.
  • A warm shower or steam can make breathing easier for some people.

When to be careful

  • If congestion comes with trouble breathing, chest pain, high fever, or lasts more than about 10 days, it’s worth getting medical advice.
  • If you use decongestant sprays, don’t use them longer than recommended, because overuse can worsen congestion.

Simple bedtime routine

  1. Use saline.
  2. Take a warm shower or breathe steam for a few minutes.
  3. Sleep propped up.
  4. Choose the side that leaves the blocked nostril uppermost.

If you want, I can also give you a very short “tonight only” routine for getting to sleep faster when your nose is blocked.
