Teens' sleep habits linked to high blood pressure

Researchers in Cleveland looked at the sleep habits of over 200 boys and girls ages 13 to 16. Eleven percent of them slept less than 6 1/2 hours a night and 26 percent had poor sleeping habits.

Results showed that one of every seven teens in the study had either hypertension or borderline high blood pressure. Teens with less than 85 percent sleep efficiency had nearly three times the odds of high blood pressure.

The study is published in the journal Circulation.
