Japanese Study: People with High Blood Pressure Who Get Less Than 7.5 Hours Sleep at Increased Risk of Heart Attack and Stroke

Reliable study of more than 1,200 Japanese adults with high blood pressure found that people who slept for less than 7.5 hours each night were more likely to suffer a heart attack or stroke or die of cardiac arrest over a 4-year period. Man women who slept less than 7.5 hours per night experienced a 68% higher risk of heart attacks, cardiac arrest or strokes.

“Short sleepers” — people who fail to have a blood-pressure dip that normally occurs overnight were at even higher risk.
