It's been linked to everything from age to weight and smoking and booze.
But research now suggests snoring – as well as tiredness – could be down to traffic pollution.
A study has shown those living close to busy roads or whose bedrooms are nearer highways are more likely to snore.
And the noise from vehicles rattling by is also believed to disrupt sleeping patterns, leaving us tired and restless.
The toxic gases and particles released by engines, particularly those powered by diesel, are said to be the cause.
A study of 12,000 people found 25 per cent of men snored heavily at least three nights a week, with those exposed to traffic pollution being at the highest risk.
Around a quarter of women admitted feeling sleepy during the day, which increased if exposed to traffic pollution.
Ane Johannessen, an epidemiologist at Bergen University in Norway, said: 'We know that people exposed to secondary cigarette smoking are more likely to snore, so we wondered if the toxins from traffic pollution might also be linked to snoring.'
