Snoring itself, without the more serious sleep apnea disorder, does not increase mortality or cardiovascular disease.

A world-first study discovered that those who snored most of the night had no greater risk of death over the next 17 years than people who snored only 12% or less of the night, or not at all.

The study helps clarify long-term risks after some clinic or hospital-based studies that had found suggestions that snoring alone might increase stroke risk.
