Sleep v stroke.

Dr Alan Flint of the Harvard School of Public Health found that long sleep was associated with an increased risk of stroke in women, but short sleep was not.

Dr Flint tracked 70,000 female nurses, aged 40-65, from 1986 to 2006, checking on hours of sleep and incidents of stroke, whether fatal or non-fatal.

After adjusting for other known factors, sleep of 10 hours or more per night was linked to a 63% increase in the risk of stroke, compared to those on 7 hours a night. Women sleeping 6 hours or less per night, or 8 to 9 hours, did not appear to be at higher risk than the 7 hour group.

The research team could not find any biological pathway between long sleep and stroke, so the association remains unexplained.

The study was presented at the American Heart Association meeting in Chicago and has not yet been published in a peer-reviewed journal.

Dr Flint stated that he is performing the same analysis for a large group of males, as no research on this topic has yet been reported.
