Blood Pressure Chart: Complete Guide to High, Low, and Normal Readings

Simple Guide To Understanding Blood Pressure Readings

Half of all American adults have high blood pressure, also called hypertension, yet many don’t even know it. High blood pressure occurs when blood flows through your arteries at higher-than-normal pressures. Recently, cases of high blood pressure have been rising rapidly in the U.S. and globally. As these numbers climb, regularly checking your blood pressure becomes essential.

According to the 2025 <span>American Heart Association Statistical Update</span>, nearly half of U.S. adults, around 122 million people, have high blood pressure, a leading preventable cause of heart disease, stroke, and early death. Shockingly, only about one in four have their condition under control. To help you stay on top of your numbers, here’s a detailed guide to understanding blood pressure.

<span>Blood Pressure Readings</span> ExplainedBlood pressure is written as two numbers separated by a slash, such as 120/80 mm Hg, which can be read as “120 over 80 millimeters of mercury.”

The first number, or systolic pressure, measures the force of blood against artery walls when the heart pumps.

The second number, or diastolic pressure, measures the pressure when the heart rests between beats.

Blood pressure naturally changes throughout the day depending on activity, stress, and other factors. A healthy reading is less than 120/80 mm Hg. Blood pressure is considered high when systolic readings are 130 mm Hg or higher or diastolic readings are 80 mm Hg or higher.

<h2><span rel="noindex">New Blood Pressure Guidelines</span> by the American Heart Association</h2>In August 2025, the AHA and ACC updated blood pressure guidelines to emphasize early intervention and personalized care. Key points include:

<ul><li>Earlier Treatment: People with a 10-year cardiovascular risk of 10% or more are advised to start medication along with lifestyle changes.</li><li>Personalized Risk Assessment: Doctors may use the PREVENT calculator to estimate 10-year risk of heart attack, stroke, or heart failure.</li><li>Expanded Lab Testing: Tests such as the urine albumin:creatinine ratio help tailor treatment plans.</li><li>Lifestyle First: Limit sodium intake to 1,500 mg per day, maintain a healthy weight, and stay physically active.</li><li>Alcohol Limits: Men: 2 drinks/day; women: 1 drink/day.</li></ul>

<h2><span rel="noindex">Blood Pressure Monitoring</span></h2>The American Heart Association recommends that everyone with high blood pressure monitor their readings at home. Home monitoring helps healthcare professionals track whether treatments are effective and can also help confirm a diagnosis of high blood pressure. However, it does not replace regular doctor visits, and you should never stop taking prescribed medication without consulting your healthcare provider, regardless of your home readings.

Home monitoring is particularly important for:

<ul><li>Anyone already diagnosed with high blood pressure.</li><li>People starting or adjusting high blood pressure treatments, to see if they are working.</li><li>Individuals who require closer monitoring, especially those with risk factors for high blood pressure or related health conditions.</li></ul>High blood pressure often shows no obvious symptoms, making regular monitoring crucial. Understanding your readings is the first step in protecting your heart and overall health. Adopting healthy habits, balanced eating, regular exercise, and stress management can significantly reduce your risk. Even small, consistent changes today can lower the chances of serious complications like heart disease and stroke in the future.
