More sleep news to share today. Usually when I think about all the sleep I've missed since my son was born I think about the short-term effects of being tired, irritable (who, me?) and lower-functioning. But researchers are warning about the long-term effects of getting both less than 7 hours of sleep a day and also of getting more than 7. 7, it seems is the magic sleep number.
An article by researchers at West Virginia University just published in the journal Sleep (which we're thinking we should start subscribing to) describes the health risks (which include heart attack, stroke, angina and heart disease) for people who sleep less than seven hours a day including naps. In Goldilocks fashion, however, people who sleep nine or more hours a day also had an increased risk of cardiovascular disease (1.5 times more than 7-hour sleepers). Seven, apparently, is just right.
How many hours of sleep are you getting?
