Is snoring harmful to my health?
The severity of this disorder varies: It can be a mild nuisance that disturbs a restful night's sleep or a symptom of the more serious, progressive sleep apnea syndrome. A history of snoring may precede development of more serious sleep disorder symptoms, including excessive daytime sleepiness, memory impairment, morning headache, poor work performance and loss of sexual drive. While snoring by itself is not life threatening, it can interfere with a good night's sleep for you, the snorer, and also affect your partner's ability to get quality sleep. Scientific research has found that partners of snores lose up to an hour of sleep a night because of the nuisance.
