Many people sleep with their mouths covered at night to avoid the cold and feel warm. But this habit can cause many health problems. Let us know about the major disadvantages of doing so.
Covering the mouth limits the flow of air. This can increase the chances of getting less oxygen during sleep.
The air coming into contact with the pillow or blanket can cause sweating and dryness on the face. It can also cause spots and rashes on the skin.
In winter, many people sleep with their mouths covered with a quilt, but with the mouth covered, it is difficult to breathe. This can make sleep shallow and restless.
A covered mouth can breathe cold and stifling air. This can lead to throat irritation, cough and cold symptoms.
Sleeping with your mouth covered continuously can affect body temperature and oxygen levels. This can weaken the immune system and increase the risk of viral or bacterial infections in winter.
Dust and allergens are trapped in blankets or covering things. By sleeping with your mouth covered, it can enter the body with the air inhaled.
Having limited breathing space can aggravate respiratory problems such as asthma or bronchitis. Therefore, avoid sleeping with your mouth covered.
