why does my throat hurt at night
Last updated September 6, 2026.
Your throat hurts more at night mainly because lying flat lets mucus, dry air, or stomach acid sit against your throat for hours instead of being swallowed away. Postnasal drip from allergies, sinus congestion, or a cold pools in the back of the throat once you're horizontal. Dry indoor air, especially with heating or AC running, dries out throat tissue overnight. Acid reflux (GERD) is a common but under-recognized cause, since lying down makes it easier for stomach acid to travel up the esophagus. Mouth breathing or snoring, common with nasal congestion or sleep apnea, dries the throat further. A humidifier, sleeping with your head slightly elevated, and treating the underlying cause (allergies, reflux, or congestion) usually help within a few nights.
What to do
- Run a humidifier: Add moisture to your bedroom air, especially in winter or with heating or AC running overnight.
- Elevate your head: Prop yourself up with an extra pillow to reduce acid reflux and postnasal drip pooling in your throat.
- Time your last meal: Avoid eating, alcohol, or caffeine within 2 to 3 hours of bedtime if reflux may be the cause.
- Treat congestion: Use saline rinses or an antihistamine before bed if allergies or a stuffy nose are driving postnasal drip.
- Watch for mouth breathing: Note if you snore or wake with a very dry mouth, which can point to nasal blockage or sleep apnea.
- Get checked if persistent: See a clinician if soreness happens most nights, includes heartburn, or lasts beyond two weeks.
