A blood pressure of 105/67 mmHg is a good reading. It falls squarely within the “normal” category under the current guidelines from the American Heart Association and American College of Cardiology, which define normal blood pressure as below 120/80 mmHg. You’re well under both thresholds, and this reading is associated with low cardiovascular risk.
Where 105/67 Falls on the Scale
The 2025 AHA/ACC guidelines break adult blood pressure into four categories based on office readings:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic or 90 or higher diastolic
At 105/67, both your top number (systolic) and bottom number (diastolic) sit comfortably in the normal range. The systolic number reflects the pressure in your arteries when your heart contracts, and the diastolic number reflects the pressure between beats. Both matter, and both of yours look healthy.
These categories apply to all adults regardless of age. The current guidelines don’t set different thresholds for younger versus older people, a change from older recommendations that used to allow higher readings for people over 65.
Cardiovascular Risk at This Level
Maintaining a systolic pressure in the low 100s is generally protective against heart disease and stroke. Research from the National Heart, Lung, and Blood Institute has examined cardiovascular risk across blood pressure ranges and found that risk begins to climb as systolic pressure rises above the low 100s. For context, your reading of 105 sits right in a range that carries minimal additional cardiovascular risk compared to even lower numbers.
The relationship between blood pressure and heart risk is continuous, meaning there’s no magic cutoff where danger suddenly appears. But practically speaking, people who maintain readings like yours over time tend to have significantly lower rates of heart attack, stroke, and heart failure than those with readings in the elevated or hypertensive ranges.
When a Low-Normal Reading Could Be a Concern
A reading of 105/67 is not considered low blood pressure (hypotension) by clinical standards. However, blood pressure is personal. What matters more than the number itself is how you feel. If you’re experiencing any of the following symptoms regularly, your blood pressure may be running too low for your body:
- Dizziness or lightheadedness, especially when standing up
- Blurred or fading vision
- Fainting or near-fainting episodes
- Persistent fatigue or feeling sluggish
- Trouble concentrating
- Nausea
If none of those sound familiar, your reading is simply healthy. Many people naturally run in the low 100s systolic and feel perfectly fine. This is especially common in people who exercise regularly, since consistent aerobic activity lowers resting blood pressure throughout the day. Younger adults and women also tend to have lower baseline readings.
Factors That Shift a Single Reading
One thing worth knowing: a single blood pressure reading is a snapshot, not a diagnosis. Your numbers fluctuate throughout the day based on hydration, physical activity, stress, caffeine, body position, and even the time of day. A reading taken right after exercise, first thing in the morning, or while dehydrated can be noticeably different from one taken mid-afternoon at rest.
If you took this reading at home, the most accurate approach is to sit quietly for five minutes, keep your feet flat on the floor, rest your arm at heart level, and take two or three readings a minute apart. The average of those readings gives you a more reliable picture. A one-off reading of 105/67 is reassuring, but tracking your numbers over a few days or weeks gives you and your doctor much better data to work with.
What This Means During Pregnancy
If you’re pregnant and wondering about this reading, the American College of Obstetricians and Gynecologists uses the same threshold: normal blood pressure during pregnancy is below 120/80 mmHg. A reading of 105/67 fits that definition. Blood pressure often dips slightly during the first and second trimesters before rising again closer to delivery, so a reading in this range is typical and expected during those stages. The numbers your care team watches for are readings above 140/90, which can signal complications like preeclampsia.
