Sleep snoring is not to be taken lightly! Snoring like thunder, beware of the silent sleep health killer ~ sleep apnea quietly, sleep apnea is a common, but under-diagnosed health problems, sleep, breathing repeated interruptions in the suspension and resumption of invisible hypoxia, in addition to low blood oxygen, the brain is prone to wake up the body, resulting in shallow sleep or sleep and wake up, frequent fluctuations in blood oxygen throughout the night will also affect the blood pressure, cardiac and other new vascular health, during the day! In addition to excessive fatigue, irritability, or difficulty concentrating, it will also increase the risk of cardiovascular disease, neurodegenerative disease, and metabolic disease. If the brain's hypoxia awakening mechanism is weak, long-term sleep hypoxia is likely to increase the risk of dementia by two times. The reasons for the lack of medical diagnosis of sleep apnea mainly come from the inability to visually connect the symptoms with the disease, the lack of awareness of the potential patients, and the inconvenient limitations of the overnight sleep polyphysiological examination of PSG (polysomnography) in sleep centers such as the presence of many interferences, the high cost, and the high rate of error, etc. In addition to the unfamiliar environment of difficulty in falling asleep during the sleep examination, it is also easy to wear the polyphysiological patches in the same time. In addition to the difficulty of sleeping in an unfamiliar environment, wearing multiple physiological patches at the same time may cause discomfort and increase sleep disturbance, or the test device may fall off due to rolling over, etc. All of the above interfering factors may lead to a high error rate of the data from a one-night, single test, or the inability to comprehensively understand the patient's condition, and in addition to a small number of beds in the sleep centers, which makes it time-consuming to make a reservation and difficult to find a bed, and a high cost of the one-night, single test, and inability to monitor and track the patient's condition in a long period of time.
