High blood pressure, or hypertension, affects about 33 percent of Americans — almost 78 million people.

If that stat seems staggering, consider athletes in the National Football League: 91 percent of the largest players have high blood pressure or prehypertension, and 78 percent of the smallest do.

We know you want to take control of your blood pressure, and the NFL for sure wants to protect its players from strokes and heart attacks that it can trigger.

With the multiple recalls of antihypertensive medications, there's no time like the present to focus on lifestyle adjustments to prevent or control high blood pressure.

But we don't want to pressure you about your blood pressure. In fact, we just want you to take a nap.

Research presented at the American College of Cardiology's 68th Annual Scientific Session found that a daily siesta (average length 49 minutes) lowers blood pressure as well as reducing salt and alcohol intake do.

And it works almost as well as taking low-dose antihypertensive medications.

The nappers (average age 62) saw their top number go down 5 mmHg. (Your targets: 120 mmHg over 75mmHg.)

That reduction matters, they explain, because “a drop in blood pressure as small as 2 mmHg can reduce the risk of cardiovascular events such as heart attack by up to 10 percent.”

So don't let anyone nag you about napping. Tell them it's a heart-healthy habit that will extend and increase your productivity.
