Too much sleep linked to ill health

More than seven or eight hours a night of sleep is associated with higher risk of premature death

Sleeping longer than the recommended seven or eight hours a night has been linked with a higher risk of premature death, according to new research.

Researchers looked at data from 74 studies involving more than three million people and found those who slept for 10 hours were 30% more likely to die prematurely than those who slept for eight.
