Sleep apnoea, related with snoring and dangerous pauses in inhalation, could almost double the risk of fatal cancer threat as those who sleep deeply, says a study.
The largest study of its kind found that fatalities with the highest oxygen deficiency in apnoea were at the highest risk. The sleep disorder is already related to fatness, heart disease, diabetes, day-time weakness and high blood pressure.
Sufferers are advised action because maintaining oxygen levels at night may cut the risk of developing related illnesses. At least half a million Britons are affected, typically middle-aged, overweight men, who may stop inhalation hundreds of times a night.
The condition causes the muscles in the airway to crumple during sleep, cutting off breathing for 10 seconds or more before brain signals force the muscles to work once more, the Daily Mail reported.
