In life, snoring is a very common phenomenon. As this phenomenon is commonplace, many people do not take it seriously and even consider it a sign of a good sleep. Snoring is a small thing, but it is very harmful to health. Data show that for every 100 people, there are 3 to 5 people who snore, and for every 5 people who snore, there is one with obstructive sleep apnea syndrome. In fact, snoring is a disease. And more seriously, among the sleep disorders, sleep apnea syndrome (commonly known as snoring) is the most dangerous condition, with 3,000 people dying every day worldwide due to snoring, and more than 100,000 people dying every year alone as a result. In many epidemiological surveys on snoring, it can be found that overweight people account for a significant proportion of snorers, a result that is inseparable from the causes of snoring symptoms. In the process of breathing, air goes from the nose to the back of the mouth, then enters the lungs through the throat and trachea, and is later expelled. During this process, if the airway becomes narrow or blocked in some parts, resulting in increased airway resistance and inspiratory effort, small turbulences may be generated in the main airflow, which in turn resonate with some tissues and produce a very annoying noise. MRI has shown that obese individuals have increased fat deposits around the pharyngeal airway, especially in the soft palate and on the posterior sides of the airway. These fat deposits can squeeze the airway and lead to narrowing of the upper airway. Some centrally obese individuals have a significantly higher airway weight load when in the prone position, which increases the likelihood of airway obstruction during sleep. In addition, obesity can reduce lung function and can cause some abnormalities in neural activity. All of these can contribute to the increased susceptibility of obese people to sleep apnea syndrome. Moreover, fat people with sleep apnea syndrome are often accompanied by sleep defects, daytime napping, fatigue, as well as bradycardia or arrhythmia and EEG arousal state, poor sleep at night, feeling fatigue, sleepiness, lack of energy during the day, morning headache, sluggishness, and decreased memory, concentration, judgment and alertness. Depression, anxiety, dry mouth, loss of libido and high blood pressure may occur. Snoring is not a trivial matter, so be careful!
