Blood pressure refers to the force of blood pushing against the walls of your arteries as your heart pumps. It’s a vital sign of overall cardiovascular health — and when levels get too high or too low, the risk of serious complications rises. Problems like heart attack, stroke, and kidney damage can all stem from abnormal blood pressure. The good news? Monitoring and managing your blood pressure is straightforward with the right tools and habits. Here’s what to know about healthy ranges, key risk factors, and the lifestyle changes that can help keep your numbers in check.
Home blood pressure monitors make checking levels easy, but manual methods can work too. To measure manually, wrap the cuff around the upper arm and rest the arm, palm up, on a level surface. Inflate the cuff to 20–30 mm Hg above the expected pressure. Using a stethoscope at the inner elbow, listen for the first whooshing sound of blood flow — this marks the systolic pressure. When the sound disappears, note the diastolic pressure. These two numbers reflect your heart’s activity during and between beats.

Blood pressure is measured using two numbers. The top number (systolic) reflects pressure when the heart beats. The bottom number (diastolic) shows pressure between beats. Both are measured in millimeters of mercury (mm Hg), a unit carried over from early pressure gauges. Together, these numbers offer a snapshot of how hard your heart is working to pump blood.

A normal blood pressure reading falls between 90/60 mm Hg and 120/80 mm Hg. Readings above 120/80 but below 140/90 are considered elevated and may signal prehypertension. Anything over 140/90 is classified as high blood pressure, or hypertension, which raises the risk of cardiovascular problems. Levels below 90/60 are considered low blood pressure and may cause symptoms like dizziness or fainting.

To track blood pressure accurately, take readings at different times throughout the day and use the highest as a baseline for future checks. Measure with your arm supported and relaxed at heart level. Avoid caffeine, exercise, or smoking for 30 minutes beforehand. Monitoring during symptoms, such as dizziness or lightheadedness, is also helpful.

A heart-healthy diet can significantly impact blood pressure. Reducing sodium intake and increasing potassium — from foods like bananas and leafy greens — helps balance fluids and ease pressure on arteries. Limiting processed foods, saturated fats, and refined carbs also supports healthy levels. Keeping a food journal may help track and maintain beneficial eating habits.

Physical activity is a proven way to support healthy blood pressure. Aim for at least 150 minutes of moderate aerobic exercise weekly — activities like walking, swimming, or cycling. Strength training can also help, especially when combined with cardio. A doctor or trainer can recommend routines tailored to your fitness and cardiovascular goals.

Yes. Excessive alcohol consumption can raise blood pressure. Heavy drinking, even short-term, causes spikes that may become long-lasting. To minimize risk, limit intake to one drink per day for women and men over 65, or two for younger men. Alcohol can also contribute to weight gain, which indirectly affects blood pressure.

Managing stress is essential for controlling blood pressure. Activities like yoga, meditation, and listening to music can reduce tension and help keep levels in check. Because stress responses vary, each person should explore techniques that fit their needs and lifestyle.

Blood pressure often rises in cold weather because narrowed blood vessels require the heart to work harder. In contrast, it may drop slightly in warmer temperatures. Other weather conditions — like humidity, wind, or atmospheric pressure — can also cause fluctuations. Maintaining consistent indoor temperatures can help stabilize readings.

One popular claim is that red wine is good for your heart, but regular alcohol consumption may raise blood pressure. Another is that kosher or sea salt contains less sodium — in reality, all table salts have roughly the same sodium content. If in doubt, talk to a doctor to separate fact from fiction.
