Do you wake up every morning with a dry, sticky mouth, even when you drank water before going to bed? This experience is common, but when it happens regularly, it may be worth understanding the possible causes.
1. Sleeping with your mouth open: Breathing through your mouth during sleep allows moisture to evaporate, leaving your mouth and throat dry.
2. Nasal congestion: A blocked nose caused by allergies, a cold or sinus problems can make you breathe through your mouth at night.
3. Not drinking enough fluids: Dehydration can reduce saliva production. You may notice dryness alongside thirst, darker urine or headaches.
4. Certain medications: Some medicines used for allergies, depression, high blood pressure and other conditions can cause dry mouth as a side effect.
5. Diabetes: Persistently high blood sugar can cause increased thirst and frequent urination. Some people also experience a dry mouth.
6. Sleep apnoea: This condition causes repeated interruptions in breathing during sleep. Loud snoring, gasping and daytime tiredness may occur alongside morning dry mouth.
What can help?
Drink enough water throughout the day, maintain good oral hygiene and address nasal congestion with appropriate medical advice. Sugar-free gum may also stimulate saliva during the day.
If dry mouth continues, causes difficulty swallowing or comes with excessive thirst and frequent urination, speak with a healthcare professional.
Persistent dry mouth should not simply be dismissed as a normal part of waking up.
