People with bedtime snoring and breathing problems may be using up far more calories while they sleep.

Those with the worst sleep apnoea symptoms burned 373 extra calories a day compared with those with only mild symptoms, US researchers found.

Nervous system changes triggered by the condition may be responsible.

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

It has also been linked to a greater risk of high blood pressure and cardiovascular problems.
