Blood Pressure Archive

Blood pressure is the push of blood through the body, like water through a hose. Pressure depends on how hard the heart pumps, how much blood there is, and how tight small vessels are, all influenced by hormones, salt, fluids, and stress.

Many home blood pressure monitors are not validated for accuracy, which means there's no way to know if information they provide is correct. Relying on inaccurate measurements can affect decisions people make about medical treatment. Fortunately, reliable organizations have developed lists of blood pressure monitors that have demonstrated clinical accuracy. If a blood pressure monitor isn't listed, it's probably not validated.

Pregnancy complications such as gestational diabetes and preeclampsia—marked by high blood pressure that can impair organ function and affect blood vessels—are increasingly tied to higher lifetime cardiovascular risks. Women with these complications face greater odds of heart attack, stroke, and diabetes.

When it comes to managing blood pressure, doctors tend to focus on lowering the top (systolic) number, but the bottom (diastolic) number also plays an essential role in heart health. Diastolic pressure is the pressure during the resting phase between heartbeats, and helps coronary vessels supply oxygen to the heart muscle. It's important to keep both blood pressure numbers low per guidelines, but research suggests the diastolic number should not fall too low.

An “enlarged” heart on an X‑ray doesn’t always mean trouble. Further heart imaging can help reveal what’s really going on.

Chronic pain is linked to an increased risk of high blood pressure, which may be driven in part by depression, according to a 2026 study. Mind-body therapies and medications may help.

Both systolic and diastolic readings matter. But large studies have shifted focus toward the top number. See what each reveals about heart risk.

Seasons can affect blood pressure. But winter chills, holiday weight gain, and salty comfort foods can also push readings higher as warm weather gives way to cold.

An analysis shows less than 7% of adults in the US meet the criteria for optimal cardiometabolic health. Taking small steps to help control and improve key risk factors can reduce the odds of a heart attack or stroke.

For people with high blood pressure, practicing slow, deep breathing for 15 minutes a day can potentially lower blood pressure. Helpful techniques include 4-7-8 breathing, box breathing, and belly breathing. Devices to guide breathing exercises may also be useful.
