Snorers have a higher risk of cancer.
A study has found that noisy sleepers are also more likely to develop blood clots and lose brain power faster as they grow older.
Around 1.5 million Brits suffer from obstructive sleep apnoea as the body is deprived of vital oxygen at night. The condition causes bad snoring, choking or gasping at night and experts have warned that it must be diagnosed and treated to prevent health damage.
Dr. Andreas Palm, from Uppsala University in Sweden, said: "Our findings show that oxygen deprivation due to obstructive sleep apnoea is associated with cancer.
"In the past it has not been clear whether this is due to the sleep apnoea itself or to related risk factors such as obesity, heart disease and lifestyle factors."
Sleep apnoea is a condition where someone's breathing stops for short periods while they are sleeping. It causes levels of oxygen in the blood to drop and can cause serious cell damage in some cases.
