A blood pressure of 116/64 is a good reading. It falls squarely within the normal category, which the American Heart Association and American College of Cardiology define as below 120/80 mmHg. Both your systolic number (116, the pressure when your heart beats) and your diastolic number (64, the pressure between beats) are comfortably inside the healthy range, with a few points of margin before reaching the next category.
Where 116/64 Falls on the Chart
The 2025 joint guidelines from the AHA and ACC break adult blood pressure into four categories:
- 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
If the two numbers land in different categories, you go by whichever one is higher. In your case, both numbers sit in the normal range, so there’s no ambiguity. A reading of 116/64 requires no treatment and no lifestyle changes beyond maintaining the habits that got you there.
Is the Diastolic Number Too Low?
Some people see 64 and wonder if it’s on the low side. Low blood pressure (hypotension) is generally defined as a reading below 90/60 mmHg. At 64, your diastolic pressure is well above that threshold. Most clinicians only consider low blood pressure a problem when it causes symptoms like dizziness, lightheadedness, fainting, or blurred vision. If you feel fine at 116/64, there is nothing to worry about.
Diastolic pressure naturally shifts over a lifetime. Population data shows it tends to rise until about age 50, levels off for roughly a decade, then gradually declines. So a diastolic reading in the low-to-mid 60s is common and perfectly healthy, especially in younger adults and people who exercise regularly.
How Age and Fitness Affect the Reading
Regular exercise lowers resting blood pressure throughout the day. People who are physically active often see readings in the range of 110 to 120 systolic with diastolic values in the 60s. A reading of 116/64 is typical for someone with a consistent exercise routine and is a sign the cardiovascular system is working efficiently.
As people age, systolic pressure tends to rise steadily while diastolic pressure can fall. For a younger adult, 116/64 is unremarkable in the best sense. For an older adult, this reading is still classified as normal, though absolute cardiovascular risk is higher at older ages regardless of blood pressure category. That means maintaining a normal reading becomes even more valuable the older you get.
During Pregnancy
The American College of Obstetricians and Gynecologists uses the same thresholds: normal is below 120/80 mmHg. A reading of 116/64 during pregnancy is healthy. Blood pressure is monitored at every prenatal visit because complications like preeclampsia can push numbers up quickly, but a baseline of 116/64 is exactly where you’d want to start.
Getting an Accurate Reading at Home
A single reading can be misleading. Blood pressure fluctuates throughout the day based on stress, caffeine, hydration, posture, and even whether you’ve recently used the bathroom. If you’re checking at home, a few steps make a real difference in accuracy.
Empty your bladder first. Sit quietly for five minutes before measuring. Your back should be supported against a chair, both feet flat on the floor, legs uncrossed. Place the cuff on your bare upper arm (not over clothing) so it sits at heart level, with the lower edge just above the crease of your elbow. Don’t talk or look at your phone during the reading. An upper-arm cuff is more reliable than a wrist model, and the cuff size matters: one that’s too small will give a falsely high number.
Taking two readings a minute apart and averaging them gives you the most dependable result. If you consistently see numbers below 120/80 across multiple readings on different days, you can be confident your blood pressure is genuinely normal.
Keeping It in the Normal Range
The official recommendation for people with normal blood pressure is simple: maintain or adopt a healthy lifestyle. That means regular physical activity, a diet with plenty of fruits, vegetables, and whole grains, limited sodium intake, moderate alcohol consumption, and a healthy weight. These are the same habits that lower elevated blood pressure, but starting from a normal baseline means you’re protecting a good position rather than trying to recover one.
Systolic pressure creeps upward with age in most people, so what’s normal today can shift into the elevated category over years. Periodic checks, whether at a pharmacy, at home, or during routine medical visits, help you catch any gradual climb early. At 116/64, you’re in a strong position.
