What is the proper blood pressure, and is lower always better?

Normal blood pressure is below 120/80 mm Hg (read as "120 over 80"). The top number (systolic) measures pressure when your heart beats, while the bottom number (diastolic) measures pressure when your heart rests between beats.

What is the proper blood pressure, and is lower always better?

Normal blood pressure is below 120/80 mm Hg (read as "120 over 80"). The top number (systolic) measures pressure when your heart beats, while the bottom number (diastolic) measures pressure when your heart rests between beats.

Here's how blood pressure categories break down:

* Normal: Below 120/80 mm Hg
* Elevated: Systolic 120-129 and diastolic below 80 mm Hg
* Stage 1 Hypertension: Systolic 130-139 or diastolic 80-89 mm Hg
* Stage 2 Hypertension: Systolic 140 or higher or diastolic 90 or higher mm Hg

Lower isn't always better for everyone. Most healthy adults should aim for below 140/90 mm Hg, but if you have heart disease or are at high risk, your doctor may recommend keeping it below 130/80 mm Hg. Your target depends on your individual health situation. Should you log how you feel at different readings?

Yes, tracking how you feel alongside your blood pressure readings can be really helpful! A MyHeartDiseaseTeam member shared experiencing shortness of breath and dizziness with high blood pressure readings, which prompted them to reach out to their doctor.

When monitoring at home, consider noting:

* Your blood pressure numbers
* Any symptoms (dizziness, shortness of breath, headaches, chest discomfort)
* Time of day
* Recent activities or stress levels

For accurate home readings, rest quietly for five minutes first, take readings twice daily over 5-7 days with at least two readings each time, and avoid smoking, exercise, or caffeine for 30 minutes beforehand. Home monitoring is valuable because it avoids "white coat syndrome" where anxiety at the doctor's office can temporarily raise your readings.

If your blood pressure reaches 180/120 mm Hg or higher, seek medical help immediately.
