If you having trouble breathing while you sleep and wake up the next morning with a dry, itchy throat, you may have a chronic mouth breathing problem. According to Dr. Joseph Sarkissian, DDS, mouth breathing, if left untreated, can result in undesired side effects like snoring and future health issues like immune deficiencies. Although you are able to control your mouth breathing during the day, you may suffer from it unconsciously at night. Many people suffer from mouth breathing, which can be addressed with several methods.
Wash your bedding and clean or replace your home's air filters. Nasal congestion can be caused by allergens on bed sheets and in the air. Keep your house clean to help reduce pollen and other irritating particulates that can affect your nasal passages.
Wear an over-the-counter nasal strip, use a nasal spray or put on a chin strap. Chin straps restrict your mouth from opening while you sleep so you are able to breath through your nose. Nasal strips and nasal sprays allow constricted nasal passages to open up so you don't have to use your mouth as your primary airway.
Elevate your head's resting position. Sleeping on your back with your head in a certain position can cause your mouth to open while you sleep. Certain pillows are designed to elevate your head and reduce and neck strain while maintaining comfort. Elevating your head can help reduce nasal drip and open up nasal passages to eliminate congestion.
Consult a physician if nasal congestion or mouth breathing problems persist. Constant mouth breathing while sleeping can be caused by dental issues, sleep apnoea and other conditions.
