Understanding Your Blood Pressure

不可不知的血壓
Find out what your blood pressure numbers really mean 血压数据学问大 by Pamela Osment

You go for a doctor’s visit. When you see the doctor, a nurse wraps a blood pressure cuff around your arm. The cuff squeezes your arm and gives the nurse two numbers. These numbers are your blood pressure.
Both numbers measure the amount of pressure placed on the inside of your blood vessels. The top number measures the pressure while your heart is pumping. And the bottom number measures the amount of pressure while your heart is resting between beats.

Watch those numbers!
In adults, healthy blood pressure numbers should be 120/80 or less. These numbers show that blood moves easily through your body at the right rate. High blood pressure begins at 140/90, putting you at risk for heart disease. The higher your blood pressure, the greater the risk.

Keep it low
In order to prevent high blood pressure, you should maintain a healthy weight. Exercise regularly and eat healthy foods. Don't eat too much salt, and avoid alcohol and cigarettes. By doing these simple things, you should pass your blood pressure test with flying colors!

More Info
Accounting to the website HeartHub, about one in three adults in the U.S. has high blood pressure but one third of them don't even know it. That's why high blood pressure is sometimes called the "Silent" killer. Uncontrolled high blood pressure can lead to stroke, heart attack, heart failure or kidney failure. The only way to know if you have high blood pressure is to get it checked.
