If your mouth feels dry at night, several factors could be to blame.
Poor food choices before bed — like greasy, spicy, or salty meals — can irritate your digestive system and pull water from your body as it works to process them, leaving your mouth dry by morning.
Liver issues may also cause toxins to build up, and one subtle warning sign is waking up repeatedly with a dry mouth. If this occurs often, it’s important to speak with a doctor.
Dehydration is another common cause. Your body still loses water while you sleep, so not drinking enough throughout the day can easily lead to dryness at night.
