People whose mouths feel dry when sleeping at night need to know these 8 reasons

1. Digestive Issue

Eating certain types of food before bed—especially greasy, spicy, or salty foods—can irritate the digestive system. These foods absorb water and increase fat and blood pressure levels, which disrupt digestion during the night.

As your body continues to digest the food while you sleep, it pulls water from your system, leading to a dry sensation in your mouth.

2. Liver Problems

The liver plays a vital role in filtering toxins from the body. When it is inflamed or not functioning properly, toxins can build up in the system.
