There are many risk factors lurking in snoring. In severe cases, it is often accompanied by a pause in inspiration. Sometimes the pause lasts for a few seconds, sometimes up to a minute or more. You may have a loud snore when the whistling resumes, and then you may wake up suddenly. You are unaware of this. In the morning, you may feel tired and have a headache, or a sore back and legs. You feel exhausted all the time, want to sleep, have trouble concentrating and are irritable. You may even experience falling asleep while driving. So what is apnea? Why does it happen? Let me take you deeper into it! Apnea is also known as asphyxia. Sleep apnea is the inhibition of inspiration during sleep. Physicians classify it into two types: central and obstructive (of course, there is also a mixture of both forms). As the name implies, obstructive sleep apnea is caused by an obstruction of the upper airway. During sleep, the muscles of the whole body, including the pharyngeal muscles and the soft palate, are relaxed and the tongue drops back, resulting in the occlusion of the upper airway. At the same time, the brain continues to send signals to our main inspiratory muscle (diaphragm), urging it to keep working. This activity increases the negative pressure in the airway, which leads to narrowing and complete closure of the airway. If there are 5-10 pauses in inspiration in an hour, each lasting more than 10 seconds, the body is in a very dangerous state, because this condition will lead to a lack of oxygen in the organism. The body ends the whistling pause by sending an alarm signal to the brain. Doctors call this holding awake. If the patient is always disturbed by held awakenings, he or she does not get enough sleep. The time of multiple dream periods is often compressed or disturbed. This is the cause of various symptoms of daytime and nighttime disturbances. Mild sleep apnea syndrome OSAHS (5-15 inhalation pauses in 7 hours of sleep) or simple snoring does not have much effect on health and can be improved by changing sleep position and active exercise. If the number of sleep apnea is 15-30 (moderate) or more than 30 (severe), the blood oxygen is less than 90, which will have a greater impact on the cardiovascular and cerebrovascular, and can lead to hypertension, coronary heart disease, diabetes and cerebrovascular accidents, and even sudden death in sleep. Because OSAHS patients suffer from daytime sleepiness, poor concentration, low work efficiency, and are especially prone to traffic accidents and safety hazards, many health organizations around the world have classified OSAHS as a major disease that endangers human health and quality of life. Modern sleep research has delved into the diagnosis and treatment of sleep disorders and sleep apnea. The sleep whistler was born. Wearing a whistler, is now the preferred non-surgical treatment for OSAHS patients. Thousands of patients have already benefited from it. Once deep sleep is restored, patients will feel refreshed.
