A blood pressure of 98/72 is a good reading. It falls within the normal range, which is anything below 120/80 mmHg, and it sits well above the threshold for low blood pressure (hypotension), which is 90/60 mmHg. For most people, this number reflects a healthy cardiovascular system.
Where 98/72 Falls on the Scale
Blood pressure is measured in two numbers. The top number (systolic) measures pressure when your heart beats, and the bottom number (diastolic) measures pressure between beats. Here’s how the ranges break down:
- Normal: less than 120/80 mmHg
- Elevated: 120 to 129 systolic with a diastolic under 80
- High blood pressure: consistently at or above 130/80 mmHg
- Low blood pressure: below 90/60 mmHg
At 98/72, both your systolic and diastolic numbers are comfortably in the normal zone. Your systolic is 8 points above the hypotension cutoff, and your diastolic is 12 points above it. This is not a borderline reading in either direction.
Why a Lower Normal Reading Is Often a Good Sign
Blood pressure on the lower end of normal often reflects good cardiovascular fitness. Regular physical activity strengthens the heart so it can pump more blood with less effort, which naturally lowers resting blood pressure. Exercise also triggers the release of compounds that keep blood vessel walls elastic, allowing blood to flow through with less resistance. People who are physically active tend to have resting readings below 120/80 as a result.
Younger adults and women also tend to run lower than the population average. If 98/72 is typical for you and you feel fine, it’s a sign your heart and blood vessels are working efficiently.
One Thing Worth Checking: Your Pulse Pressure
Pulse pressure is the gap between your top and bottom numbers. For 98/72, that’s 26 mmHg. A normal pulse pressure is around 40 mmHg, and a reading is considered narrow when it drops to one-quarter or less of the systolic number. One-quarter of 98 is about 24.5, so your pulse pressure of 26 is slightly above that narrow cutoff but still on the low side.
A consistently narrow pulse pressure can sometimes indicate that the heart isn’t pumping as forcefully as expected. In isolation, a single reading of 26 is not alarming, especially if you feel well. But if you check your blood pressure regularly and notice the gap between the two numbers stays very tight, it’s worth mentioning at your next checkup.
When Lower Blood Pressure Becomes a Problem
Blood pressure only counts as “too low” when it causes symptoms. The number itself matters less than how you feel. Signs that your blood pressure may be dropping too low include lightheadedness, fainting, weakness, blurry vision, nausea, and fatigue. These symptoms tend to be most noticeable when you stand up quickly or after eating a large meal.
At 98/72, you’re above the clinical hypotension threshold, so these symptoms would be unusual. But blood pressure fluctuates throughout the day. Dehydration, heat, skipping meals, and certain medications can all push it lower temporarily. If you’re someone who naturally runs on the lower end, those additional dips can occasionally bring on symptoms even if your baseline reading looks fine.
What Could Push It Lower
Since your reading is already on the lower side of normal, a few things are worth being aware of. Standing up too quickly can cause a temporary drop, a phenomenon called orthostatic hypotension. Hot weather and hot showers dilate blood vessels and can lower pressure further. Alcohol and large carbohydrate-heavy meals can do the same. Staying well hydrated and eating smaller meals more frequently helps keep blood pressure steady if you notice any lightheadedness.
Some medications for other conditions, including antidepressants, certain heart drugs, and medications for prostate issues, can lower blood pressure as a side effect. If you start a new medication and begin feeling dizzy or weak, the combination with your already lower baseline could be the reason.
How to Get an Accurate Picture
A single blood pressure reading is a snapshot, not a diagnosis. Blood pressure varies based on time of day, stress, caffeine intake, hydration, and even whether you were sitting or standing. If you’re curious about your true baseline, take readings at the same time of day for several days, ideally while sitting quietly for five minutes beforehand. The pattern across multiple readings matters more than any individual number.
If your readings consistently cluster around 98/72 and you have no symptoms, you’re in a healthy range that most cardiologists would be happy to see. High blood pressure is a leading risk factor for heart disease and stroke, so being well below those thresholds is genuinely protective over the long term.
