Are you able to recall a health care provider’s appointment throughout which your blood strain wasn’t taken? In all probability not. It’s an important signal—together with coronary heart charge, respiration charge, and physique temperature—that displays how properly your physique is functioning. However except you’ve already been identified with hypertension or one other medical situation that requires you to watch it at dwelling, chances are high you don’t usually take your personal blood strain.
“Most people, the only time they get it checked is when they’re at the doctor’s office,” Dr. Joseph Ebinger, director of the coronary intensive care unit on the Smidt Coronary heart Institute at Cedars-Sinai Medical Heart in Los Angeles, tells Fortune. “Individuals, if they have their own history of having high blood pressure measurement, or a strong family history of high blood pressure, or, finally, cardiovascular risk factors—things like diabetes or peripheral arterial disease—I would recommend that they have a blood pressure cuff at home.”
Whereas your coronary heart charge is the variety of instances your coronary heart beats per minute, your blood strain measures the power with which your blood circulates and stresses your artery partitions. You probably have hypertension, additionally referred to as hypertension, your coronary heart has to work more durable than regular to pump blood all through your physique. Over time, hypertension can result in critical medical issues together with stroke, coronary heart assault, and kidney failure.
Regardless of the hazards of hypertension, its lack of signs means individuals might not know they’ve the situation till the injury has been executed. That’s why hypertension is a “silent killer.” Half of U.S. adults have hypertension, in response to the Nationwide Coronary heart, Lung, and Blood Institute (NHLBI), however solely two-thirds of them realize it.
“It’s the No. 1 most common cardiovascular risk factor in the country,” Ebinger says. “Discovering methods to regulate it’s actually necessary in minimizing your danger, and it could actually occur early on in life.
“We know that individuals who are at increased risk for developing [hypertension] later in life tend to have higher-than-normal blood pressures in their midlife—even in their thirties—and so regular screening and monitoring of your blood pressure is key.”
What’s the distinction between systolic and diastolic blood strain?
You’ve doubtless heard your well being care supplier say your blood strain is one thing like “120 over 80,” sometimes a bigger quantity over a smaller quantity. Collectively, the 2 are measured in millimeters of mercury, written as 120/80 mm Hg. Dr. Gregory Katz, a heart specialist at NYU Langone Well being, explains the distinction.
“Blood pressure is the pressure that your arteries are experiencing during the entirety of your life, and that’s going to differ when your heart is contracting versus when your heart is relaxing,” Katz tells Fortune. “That first number of blood pressure is called the systolic number. That’s the pressure in your arteries when your heart is ejecting blood into them, and then the bottom number is called the diastolic pressure, which is the pressure in your arteries when your heart is relaxed.”
Katz provides, “The overall pressure, which is going to be an average of both the systolic and the diastolic, that’s going to be adjusted based on the fact that your heart is more often relaxing than contracting. It’s called the mean arterial pressure (MAP).”
The American Coronary heart Affiliation (AHA) considers a systolic strain under 120 and a diastolic strain under 80 to be regular for adults. Hypertension is labeled into phases of severity; Stage 1 has a systolic studying of 130 to 139 or a diastolic studying of 80 to 89. A systolic measurement above 180 and/or a diastolic measurement above 120 constitutes a hypertensive disaster requiring emergency medical care.
Hypertensive emergencies apart, do not forget that your blood strain virtually adjustments minute to minute, Katz says, so don’t let a single irregular studying alarm you.
“Any type of physical activity raises your blood pressure. Exercise, you’re supposed to have a normal blood pressure elevation when you are exerting yourself,” Katz tells Fortune. “Changing the position that you’re in, going from sitting to standing, will change your blood pressure; being stressed out will change your blood pressure; rushing will change your blood pressure. There are a million different things that are going to have an impact on what your blood pressure is.”
In case your blood strain is frequently excessive while you’re at relaxation and ease, nevertheless, ask your physician about being examined for hypertension.

Kids and teenagers can have hypertension too. As with adults, blood strain under 120/80 is regular for teenagers. For these 12 and youthful, a studying under the ninetieth percentile of their friends is good, in response to the American Academy of Pediatrics.

As of 2017, the AHA now not defines hypertension otherwise for adults youthful than 65 and these 65 and older. (Beforehand, the hypertension threshold was 140/90 for youthful adults and 150/80 for older adults.) Nonetheless, most individuals expertise an increase in blood strain as they become older, Katz says.
“I think a lot of that is related to the arteries getting stiffer, just like everything else gets stiffer as we get older,” Katz says. “The way that our arteries are going to have different levels of stiffness versus elasticity, it’s going to be partly reflective of what is our lifestyle like, and how much physical activity are we doing.”
Katz provides, “I generally tell patients, ‘You probably need more physical activity as you get older to prevent your blood pressure from going up.’ And, unfortunately, most people do less physical activity as they get older.”
