People who snore and suffer from disturbed sleep may have a heightened risk of dying from cancer, a study has shown.
Snoring is one of the main symptoms of sleep disordered breathing (SDB).
New research has shown an association between SDB and cancer death.
Experts think the link may be due to problems causing an inadequate supply of oxygen.
SDB covers a range of disorders that lead to interrupted breathing during sleep.
The latest research from the University of Wisconsin-Madison in the US also points to a connection with cancer mortality.
Scientists looked at 22 years’ worth of data on a total of 1,522 people who took part in a study of sleep problems.
The results showed an association with cancer death that increased sharply with SDB severity.
People with mild SDB were just 0.1 times more likely to die from cancer than those without the problem. But moderate SDB doubled the chances of cancer death, while severe SDB increased the risk 4.8 times.
