The Source

A study of 10,000 British civil servants published in Sleep found that cutting sleep from seven to five hours in-creased the risk of cardiovas-cular mortality and increasing sleep from seven to more than eight increased the risk of death from other causes.

The research controlled for age, sex, marital status, employment grade, smoking status, physical activity, alcohol consumption, self-rated health, body mass index, blood pres-sure, cholesterol, and other physical illness.

Expert view

Dr Chris Idzikowski, director of the Edinburgh Sleep Centre said he didn't think the study told us anything new.

"It's almost impossible to try and disentangle what's happening. One does wonder if there are minor systems failures that occur in a lifetime of sleep deprivation."

But he added that asking people how they were sleeping was useful.

"The attitude is it's not important but it is important."
