Seven is your heart's lucky number


A new study just released by the American Academy of Sleep Medicine (AASM), says seven hours of sleep is optimal for heart health.

Doctors from West Virginia University studied more than 30,000 adults and found those that slept five hours total per day had more than twice the risk of suffering from angina, coronary heart disease, heart attack or stroke than participants who slept 7 hours a day.

But that doesn't mean the more the better. Those that slept 9 hours or more a day had one and a half times the increased risk of cardiovascular disease compared to the 7-hour a day sleepers.

And those that slept 6 or 8 hours a day? They had an "elevated but less dramatic risk."
