One of the main reasons for drooling is a blocked nose, which makes a person breathe through their mouth and may lead to drooling. Cleaning and unblocking nasal sinuses could be a good way out of having a wet pillow every night. Here are some ways that can help unclog your sinuses:
a hot shower will clear the nose and allow normal breathing at night;
essential oils, especially ones containing eucalyptus, will help you breathe more freely and also help you get better sleep;
using products that help clear sinuses like Vick’s Vaporub will unclog the nose and allow for better airflow.
