Snoring is a common phenomenon in people’s daily lives. Many ordinary people think that snoring is a sign of “good sleep”, but this is not the case. Modern medical research has confirmed that severe snoring can cause great damage to health. Severe snoring can cause temporary stoppage of breathing or reduction of airflow during sleep at night, resulting in a reduction of oxygen content in the blood, causing hypoxia and damage to tissue cells throughout the body, which can trigger or aggravate hypertension, coronary heart disease, diabetes, stroke, Alzheimer’s disease and other chronic diseases, and can cause sudden death at night in severe cases. In addition, repeated breathing at night caused by snoring temporarily stops will interfere with the normal sleep structure of the human body, and many physiological processes and the secretion of certain hormones are completed during a specific sleep period, and changes in the sleep structure can cause disruptions in these physiological processes and hormone secretion, resulting in daytime sleepiness, memory loss, metabolic disorders, delayed growth and development of children and a series of other problems. So, what kind of snoring can be dangerous to health? What kind of nighttime and daytime symptoms may be caused by snoring and need to be taken seriously and promptly seen? Usually people are used to classify snoring intuitively as “benign snoring” and “malignant snoring”. The so-called benign snoring refers to the short period of snoring caused by improper sleep position or cold and nasal congestion, this snoring will disappear naturally after the improper sleep position or cold and nasal congestion and other external factors, usually does not cause significant impact on the human body, so there is no need to go to the hospital. The “malignant snoring” refers to the presence of no clear external causes, the habitual snoring phenomenon for years. This is divided into two situations: one is simply habitual snoring all year round without a clear respiratory temporary stop or airflow reduction, and the other is accompanied by repeated respiratory temporary stop or airflow reduction during sleep, which is medically known as sleep apnea hypoventilation syndrome. For people who simply snore habitually, although there is no respiratory arrest during sleep, but also need to pay attention to, because this habitual snoring if not take timely and effective intervention will gradually aggravate and eventually appear breathing temporarily stop or airflow reduction phenomenon. When the habitual snorer has poor daytime energy, drowsiness, dry mouth in the morning, dizziness, and no relief after sleep, it is time to go to a professional and regular medical institution. For patients with sleep apnea hypoventilation syndrome, timely consultation and treatment at a professional and regular medical institution is a must, because a little snoring is seriously endangering your health. In short, when there is a perennial habitual snoring phenomenon, accompanied by repeated temporary stoppage of breathing or reduction of airflow during nighttime sleep, dry mouth and dizziness in the morning, poor energy and drowsiness during the day, no relief after sleep, and memory loss, it is time to seek timely medical attention. Finally, we remind our friends that although snoring is a common phenomenon, it is a very complex pathological process, so we must go to a regular professional medical institution to avoid affecting the treatment effect and causing unnecessary losses.
