Lack of sleep 'linked to early death'

It is enough to keep you up at nights.

Getting less than six hours sleep a night can lead to an early grave, UK and Italian researchers have warned.

They said people regularly having such little sleep were 12% more likely to die over a 25-year period than those who got an "ideal" six to eight hours.

They also found an association between sleeping for more than nine hours and early death, although that much sleep may merely be a marker of ill health.

Man, oh man.

One hour too much, an hour too little and it is sayonara, bub.

The research must have been paid for by the alarm clock industry.
