Sleeping longer than the recommended seven or eight hours a night could be doing you more harm than good

Now another study says people who indulge in too much sleep, ten hours and above, have a bigger chance of dying.

"If excessive sleep patterns are found, particularly prolonged durations of eight hours or more, then clinicians should consider screening for adverse cardiovascular risk factors and obstructive sleep apnea, which is a serious sleep disorder that occurs when a person's breathing is interrupted during sleep".

Resting in bed for over 10 hours was connected to an increased risk of death from cardiovascular disease (49%), and from stroke (56%).

According to the findings, abnormal sleep is a "marker of elevated cardiovascular risk", and doctors should ask their patients during the appointments about their sleeping patterns.

"Researchers, who looked at data from 74 studies involving more than three million people, said their study suggests abnormal sleep could be 'a marker of elevated cardiovascular risk" and said Global Positioning System ought to ask questions about sleeping patterns during appointments'.

Researchers from the University of East Anglia, Leeds University, and Manchester concluded that people who sleep over eight hours a night saw an increase in heart disease by 44%.

Until now, there have only been studies on how too little sleep increases the risk of dying. The review found no difference between those who reported sleeping between seven and eight hours and those who got less than seven. Sleep affects everyone. The amount and quality of our sleep is complex.

"We further wanted to know how incremental deviation from recommended sleep duration altered risk of mortality and cardiovascular risk".

Lead researcher Dr Chun Shing Kwok, of Keele University's Institute for Science and Technology in Medicine, said: "Abnormal sleep is a marker of elevated cardiovascular risk and greater consideration should be given in exploring both duration and sleep quality during patient consultations".

"There are cultural, social, psychological, behavioural, pathophysiological and environmental influences on our sleep".
