Why do you sleep with your mouth open while sitting?

Everyone has different sleeping habits. Some people like to sleep lying on their backs, some like to sleep on their left sides, some like to sleep on their right sides, and some like to sleep on their stomachs. Of course, sleeping on your stomach is not recommended, as it is very bad for the heart. Most people breathe through their noses with their mouths closed when they sleep, which is normal. But why do some people sleep with their mouths open when they sit? Sleeping while sitting down relaxes the muscles of the jaw, making it easier to open your mouth.

1. Why do we like to sleep with our mouths open when sitting?

When you sleep sitting down, the muscles of your whole body are in a relaxed state. At the same time, the muscles controlling your mandible are also relaxed, and your mandible opens due to the control of gravity. At this time, people breathe air through their mouths. In addition, it is also possible that you cannot breathe through your nose when you sleep, which causes you to breathe through your mouth. The most likely possibility is rhinitis or an uncomfortable sleeping environment, which is a natural adjustment made by the human body.

2. The dangers of breathing through the mouth while sleeping

The human body breathes through the nose because the nasal hair and secretions in the nasal cavity have the function of filtering dust and debris, humidifying and heating the air. When you breathe through your mouth, your throat is more susceptible to pharyngitis. Many people with chronic pharyngitis have the habit of breathing through their mouths.
