All this happened, more or less.

People who get five to seven hours of sleep nightly are almost twice as likely to develop early signs of blood-vessel damage as those who get more rest, according to a five-year study published in today’s Journal of the American Medical Association. Those who regularly sleep less than five hours a night are at even higher risk.

Abnormal sleep patterns skew the release of appetite-related hormones, which may contribute to obesity and diabetes, earlier studies showed. Today’s research is the first to suggest a shorter night’s sleep may have a more direct and damaging effect on heart health, said Diane Lauderdale, the University of Chicago epidemiologist who led the research team.
