Why does my sore throat get worse at night?
Last updated September 3, 2026.
Three things gang up on your throat at night: lying flat lets postnasal drip pool onto it, dry bedroom air strips moisture, and congestion forces mouth breathing that leaves it raw by morning. Add less swallowing during sleep and nothing to distract you, and nights simply hurt more. What helps: an extra pillow to keep drip draining, a humidifier, warm salt-water gargles before bed, water sips overnight, and acetaminophen or ibuprofen before sleep when it is bad. See a doctor for a severe sore throat, one lasting past a week, or any trouble breathing or swallowing saliva. Pymander is a free AI doctor, 24/7 by text, and can help you pin down the cause.
What to do
- Sleep propped up: elevation keeps postnasal drip moving instead of pooling.
- Moisten the air: a humidifier, or even a bowl of water near a radiator, helps a dry room.
- Gargle warm salt water before bed: half a teaspoon of salt in warm water, gargle and spit.
- Get checked if it outlasts a week: or immediately for breathing or swallowing trouble.
