The payback comes in the daytime, said a UK specialist, with sleep apnoea sufferers craving food and too sluggish to exercise.

Sleep apnoea, in which the airways are partially or completely obstructed during sleep, stops the person getting a good night's rest, making them very sleepy during the day. It has also been linked to a greater risk of high blood pressure and cardiovascular problems. Scientists have been probing the link between weight gain and sleep apnoea, and the team from the University of California, San Francisco, measured the number of calories burned "at rest" by 212 patients. On average, the volunteers expended 1,763 calories a day this way, but those with the worst apnoea symptoms expended 1,999, while those with the mildest form of the condition expended an average of 1,626.
