Some people feel that a high volume of snoring is a proof of good sleep quality. In fact, snoring at too high a decibel level is a disease that can negatively affect a person’s health. 1, people with inflammation of the throat. When there is inflammation in the throat, the throat mucosa has symptoms of congestion. This is when the throat channel becomes narrow. When the airflow passes, it produces sound. If you do not normally snore, and snoring occurs after symptoms of suspected pharyngitis such as an itchy throat and foreign body sensation in the throat, you may be suffering from pharyngitis rather than improved sleep quality. 2. Mental excitement. Some people carry out mentally exciting activities before going to bed, and even after going to sleep, the nerves are still in an excited state. Another part of the people are overworked during the day, the spirit and muscles are still in a tight state at bedtime. 3, the sleeping position. Some sleep on their backs, some back who, both types of sleeping posture will make the airway is not smooth enough. After sleeping on the side, the probability of snoring will be reduced. Too much snoring represents a narrower airway, affecting the quality of one’s sleep, making one listless and experiencing a decline in learning and work efficiency. Heavy cases can have obstructive sleep apnea, which requires further polysomnography to clarify the diagnosis.
