Snoring, also called snoring, can cause apnea syndrome, which can easily induce sudden death. According to statistics, the chance of sudden death in snoring is three times higher than that in non-snoring people, because snoring can lead to general lack of oxygen and great damage to cardiovascular and cerebrovascular. If the patient is older and has cardiovascular disease, snoring at night will lead to apnea syndrome, which greatly increases the chance of sudden death. 5-year mortality rate for people aged 40-70 who snore is 11%-13%, 7-year mortality rate is 16%, and 8-year mortality rate is 37%, so the chance of sudden death for people who snore is 3 times higher than that for people who do not snore, regardless of age.
