Heavy snorers suffer damage to their DNA that can make their cells age faster and increase the risk of cancer, a study suggests.
It found they have shorter telomeres, tiny caps at the end of chromosomes – DNA molecules – that prevent genetic material from unravelling and fraying.
It is well known that shorter telomeres indicate rapid ageing and increased susceptibility to cancer.
But a team at West China Hospital in Sichuan wanted to see how DNA is affected by sleep apnoea, the snoring-related condition that disrupts breathing and makes sufferers wake dozens of times in the night.

Scientists pooled data from eight previous studies involving 2,640 patients.
The results revealed a ‘significant association’ between heavy snoring and reduced telomere length, they reported in the journal Sleep.
