Snoring is what people usually call snoring while sleeping, which is considered commonplace by most people, and some people see snoring as a sign of good sleep, so it is rarely taken seriously or linked to health and disease. However, among the huge snoring population, a large proportion of them have transient sleep apnea-hypopnea syndrome (OSA). In fact, snoring is the enemy of health, because snoring makes sleep breathing repeatedly suspended (i.e. OSA), can cause serious lack of oxygen to the brain, blood, the formation of hypoxemia, and induce hypertension, cerebral heart disease, heart rate disorders, myocardial infarction, angina, etc., and serious cases may even occur sudden death during sleep. Common causes 1, obesity: weight more than 20% of the standard weight or more, body mass index (body mass index, BMI) R25%kg/m2. 2, age: the prevalence increases with age after adulthood; the prevalence increases after menopause in women, and stabilizes after age 70. 3.Gender: There are significantly more men than women with the disease. 4.Anatomical abnormalities of the upper airway: including nasal obstruction (nasal septum deviation, turbinate hypertrophy, nasal polyp, nasal tumor, etc.), tonsillar hypertrophy above II°, soft palate relaxation, excessive length and thickness of the uvula, pharyngeal cavity narrowing, pharyngeal tumor, pharyngeal mucosa hypertrophy, tongue body hypertrophy, tongue root recession, mandibular recession, temporomandibular joint dysfunction and small jaw deformity, etc. 5, family history. 6, history of alcohol and drugs: long-term heavy alcohol consumption and/or sedative-hypnotic drugs. 7, history of smoking: long-term heavy smoking. 8, other related diseases: deviated nasal septum, nasal polyps, nasopharyngeal adenoid hypertrophy, tonsillar hypertrophy, soft palate relaxation, excessive length and thickness of the uvula, pharyngeal cavity narrowing, pharyngeal tumor, pharyngeal cavity mucosal hypertrophy, tongue hypertrophy, backward tongue root, mandibular recession, chronic obstructive pulmonary disease, long-term heavy smoking, long-term heavy alcohol consumption, sedative-hypnotic drugs, acromegaly, hypopituitarism, amyloidosis Vocal cord paralysis, post-polio or other neuromuscular disorders (such as Parkinson’s disease), long-term gastroesophageal reflux, etc. Clinical manifestations If you snore at night and have the following manifestations, you should be alert to the possibility of sleep apnea syndrome. Nocturnal manifestations: snoring and irregular snoring, open-mouth breathing during sleep, sleep rhythm disorder or recurrent apnea, repeated awakening from sleep, sleep restlessness, restless sleep at night, sleepwalking, sweating, nocturnal sleep loss, increased nocturnal urination, teeth grinding, irregular movement of hands and feet. Daytime manifestations: elevated blood pressure after waking up from sleep, morning headache, dry mouth, disorientation, significant daytime drowsiness, memory loss, slow reaction, reduced ability to work and study, inability to concentrate, emotional instability, agitation, dementia. Other: may be combined with hypertension, coronary heart disease, pulmonary heart disease, stroke and other cardiovascular and cerebrovascular pathologies, and may have progressive weight gain, serious heart, intelligence, behavioral abnormalities. Prevention and health care 1.Control weight and strengthen exercise: For obese people, we should actively reduce weight and strengthen exercise, the probability of snoring for fat people is three times that of thin people. 2. Avoid alcohol and quit smoking: alcohol has anesthetic effect, which can cause muscle relaxation and lead to snoring like thunder. Habitual snorers should be prohibited from drinking alcohol before going to bed, especially strong alcohol, and the poison in smoke stimulates the respiratory tract, causing swelling of the respiratory tract and leading to poor airway. 3.Sleep on a hard bed: For those who snore seriously, the mattress should not be too soft, and it is better to sleep on a hard bed. 4.Choose a suitable pillow: Choose a proper pillow with thickness of unilateral shoulder width as appropriate. Some people think that cushioning the pillow high helps to improve breathing, but in fact, this has the opposite effect. It is recommended to choose a pillow that is soft, elastic and of the right height to facilitate smooth breathing. 5, avoid taking certain drugs: some drugs, such as sedatives, sleeping pills, can relax the muscles, should try to avoid taking. 6, sleeping position to the right side of the best: to take a lateral sleep position, especially the right side of the sleep position is appropriate to avoid the tongue, soft palate, uvula relaxation back during sleep, aggravating the upper airway blockage. 7, keep the nasal cavity moist: use humidifier, keep the bedroom air moist can avoid dry throat and mouth, can also prevent the accumulation of excessive nasal stool in the nasal cavity. 8, bedtime maintenance: eat some honey before bedtime, honey helps lubricate the throat and smooth the airways, so you can add some honey to the tranquilizer tea you drink before bed to prevent snoring. 9, maintain healthy habits: maintain healthy habits, strengthen exercise, and maintain a good figure, all of which help solve the snoring problem that plagues sleep and quality of life.
