Snoring is common in many people during nighttime sleep, but snoring with recurrent apnea, hypoxia, and frequent awakening during sleep is a sign of a pathological state. Snoring is called “sleep apnea syndrome”. According to the statistics, the snoring problem is more serious in men, and the ratio of men to women is “6:1”. On the other hand, snoring starts earlier in men, and may occur after the age of 20, while it is later in women than in men, mostly occurring after the age of 40. In medical theory, snoring is caused by the following three reasons: 1) central diseases; 2) obstructive diseases; 3) mixed diseases. Generally speaking, adults have the most mixed symptoms and minors have the most obstructive problems. Snoring: Since the airway of snorers is usually narrower than normal, the compensatory contraction of the muscles in the throat keeps the airway open during the daytime wakefulness and no blockage occurs. However, at night when sleeping, the neural excitability decreases, the muscles relax and the pharyngeal tissues are blocked, so that the upper airway collapses and when the airflow passes through the narrow part, it generates vortex and causes vibration, thus snoring occurs, and in serious cases, breathing can be temporarily stopped, thus affecting the health of people. There are also some people who snore because of central reasons Hazard: Patients with high blood pressure and cardiovascular disease have a higher chance of snoring Snoring is likely to be caused by other physical causes. The current medical research report shows that patients with high blood pressure and cardiovascular diseases have a higher chance of snoring, and with the development of snoring, some patients show a decrease in the function of room and even urine loss; those who are more obese than normal are also more likely to snore, and patients with diseases such as chest problems, diabetes, rheumatoid arthritis, etc. are more likely to have snoring problems. If snoring at night is accompanied by the following symptoms, it is a danger signal from the body and needs to be treated immediately: sleep snoring, open-mouth breathing, frequent respiratory arrest; repeatedly waking up from sleep, sleep restlessness, induced epilepsy; sleep without relief, daytime sleepiness, drowsiness; increased blood pressure after waking up from sleep; shallow sleep, headache after waking up from sleep; sleep angina at night, heart rhythm disorder; sleep loss at night, increased nocturnal urination; memory loss, Slow reaction, reduced ability to work and study; daytime sleepiness, sleepiness that is difficult to suppress even during work, meetings and meals; impotence, loss of libido; dementia. Prevention: sleep in a side-lying position and lose weight In addition to treatment, the following methods can be adopted in daily life to reduce snoring symptoms: sleep in a side-lying position and change the habitual supine sleep; try not to drink alcohol, strong tea and coffee before sleep, and do not take certain drugs, because alcohol, sedatives, sleeping pills and anti-allergic drugs will make breathing shallow and slow, and make muscles more relaxed than usual The reason is that alcohol, sedatives, sleeping pills and anti-allergy drugs can make breathing shallow and slow, and make muscles more relaxed than usual, leading to soft tissues in the pharynx blocking the airway more easily; develop the habit of regular exercise to reduce weight and enhance lung function. Snorers who have the habit of smoking need to quit smoking immediately. Because only by keeping the nasopharynx open can snoring be reduced, and the stimulation of the nasal mucosa by smoking will only make the already blocked nasal cavity and airway worse. In addition, snorers should also prevent colds and promptly treat nasal blockage diseases.
