Excess neck fat acts like a “noose,” compressing the airway. At night, relaxed muscles cause repeated airway collapse: breathing pauses hundreds of times nightly, up to 50 seconds each — repeated cycles of hypoxia → suffocation → awakening. This intermittent nighttime hypoxia: Raises heart workload，Triggers sympathetic overactivity，Causes nocturnal hypertension and arrhythmias，Increases sudden‑death risk.

Snoring is more than just noise.In short, the harm of snoring:It causes repeated nighttime hypoxia and fragmented sleep, increasing the risk and treatment difficulty of systemic diseases such as hypertension, heart disease, cerebral infarction, and diabetes. The earlier you get checked and treated, the better for your health.
