Ways to improve the quality of sleep are once again being debated by scientists, with a number of studies being conducted to help people sleep better during the festive period.

They found that patients using a continuous positive airway pressure (CPAP) machine helped to lower cholesterol, blood pressure and stomach fat. As a result there may be a significant improvement in the health of the heart.

They analysed data from 1992, 1997 and 2006 which showed very little change in the amount of time people spent in bed.
