How Frequently to Monitor Your Blood Pressure

Blood pressure can fluctuate more than many people realize. A reading at your doctor’s office may tell one story, while another at home could say something quite different. This variation can be especially challenging if you're managing high blood pressure (hypertension), a condition that affects nearly half of U.S. adults, according to the CDC.

That’s why many healthcare professionals now recommend regular at-home monitoring not just for those already diagnosed, but also for older adults or anyone at risk for heart disease.

How Often Should You Check It?

If you're just starting to track your blood pressure at home, aim to check it twice a day once in the morning and once in the evening for seven consecutive days. This gives you and your healthcare provider a more comprehensive view of your blood pressure patterns.

Once you’ve gotten the hang of it, you can shift to once daily at the same time each day, unless your provider recommends more frequent checks.

Remember, blood pressure naturally changes throughout the day. A single number taken in a clinical setting may not reflect your usual state. That’s why routine monitoring can be a valuable tool in long-term heart health.

Who Should Monitor at Home?

• People diagnosed with elevated or high blood pressure

• Adults over the age of 65

• Individuals with a family history of heart disease

• People managing other risk factors like diabetes, obesity, or kidney issues

Tips for Getting Accurate Readings at Home

Using a home monitor is simple, but getting reliable results requires attention to detail. Follow these steps each time you take a reading:

• Empty your bladder and rest for at least 5 minutes beforehand.

• Sit comfortably with your back supported, feet flat, and legs uncrossed.

• Keep your arm at heart level on a flat surface.

• Ensure the cuff is snug and positioned properly on your upper arm.

Managing High Blood Pressure Starts With Daily Habits

If your readings trend high, the first step is adjusting your lifestyle. These simple shifts can make a big difference:

• Cut back on sodium: Aim for under 1,500 mg per day.

• Exercise regularly: Try for at least 150 minutes of moderate activity per week.

• Reduce stress: Practices like deep breathing, yoga, or mindfulness can help.

• Limit alcohol and caffeine: These can raise blood pressure in some individuals.

For many, lifestyle changes are enough to lower blood pressure into a healthy range. But if that’s not the case, medications may be necessary. It’s important to follow your prescribed plan even if you don’t feel symptoms.

"Some patients stop their blood pressure medication because they feel fine," explains Yuan Lu, ScD, an assistant professor at Yale School of Medicine. "But hypertension is often symptomless, and medication must be taken consistently to be effective."

If you notice side effects, speak with your provider. Adjusting your dosage or switching medications may help improve how you feel without sacrificing control over your blood pressure.

Monitoring your blood pressure regularly empowers you to take an active role in your heart health. It’s a small habit that can make a big impact.
