What are the dangers of chronic snoring? Snoring is bad for yourself, for other people and for society. When you snore at night, it will affect the rest of others and affect your study, work and social interaction during the day. In addition, because of the narrowing or obstruction of the airway, it can cause breath-holding during sleep, or obstructive sleep apnea syndrome, which are potentially life-threatening. The prolonged occurrence of this asphyxia can be ischemic heart disease and predispose to angina pectoris or myocardial infarction, which are some important risk factors for these diseases.
