Sleep apnoea greatly increases risk of stroke, US scientists find

Stanford study shows that people with the common sleep disorder are also five times more likely to develop atrial fibrillation

Snoring loudly and feeling tired even after a full night's sleep could leave people at an increased risk of a stroke, a study has shown.

Hundreds of millions of people globally have sleep apnoea, a disorder with symptoms including stopping and starting breathing, making snorting noises, waking up a lot and loud snoring. Many have the condition but are undiagnosed.
