A blood pressure of 106/63 is a good reading. It falls squarely within the normal category, which is defined as a systolic (top number) below 120 and a diastolic (bottom number) below 80. It’s also well above the threshold for low blood pressure, which starts at 90/60.
Where 106/63 Falls on the Scale
The American Heart Association breaks blood pressure into five categories:
- Normal: below 120/80
- Elevated: 120 to 129 systolic, with diastolic still below 80
- Stage 1 hypertension: 130 to 139 systolic, or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
- Severe hypertension: above 180 systolic or above 120 diastolic
At 106/63, both numbers sit comfortably in the normal range. You’re not close to elevated territory on the top number, and your bottom number has plenty of room before reaching any concerning threshold.
Is It Too Low?
Some people see a number in the low 100s and wonder if it’s too low. It isn’t. Clinically, low blood pressure (hypotension) is defined as a reading below 90/60. Your systolic of 106 is 16 points above that cutoff, and your diastolic of 63 is 3 points above it.
That said, there is one number worth watching. Some research has found a J-curve relationship between blood pressure and cardiovascular risk, meaning that very low readings in treated patients (those on blood pressure medication) can be associated with increased risk. The threshold where this effect appeared was roughly below 110/70. If you’re taking blood pressure medication and consistently reading around 106/63, it’s worth mentioning to your provider so they can make sure your dose is appropriate. If you’re not on medication and feeling fine, this reading is simply healthy.
The Diastolic Number Matters Too
Most people focus on the top number, but the diastolic reading of 63 deserves a glance. One clinical definition of hypotension uses a diastolic below 60 as a cutoff. At 63, you’re above that line, but not by a wide margin. A single reading of 63 is perfectly normal. If your diastolic regularly dips into the mid-to-low 50s, or you notice symptoms like lightheadedness, that would be worth tracking more carefully.
Symptoms That Would Change the Picture
Blood pressure in the normal range is only a concern if it’s paired with symptoms. A reading of 106/63 with no symptoms is simply a sign of a healthy cardiovascular system. Many younger adults, women, and physically active people run blood pressures in this range as their baseline.
The symptoms that would make any normal-range reading worth investigating include persistent dizziness or lightheadedness, feeling faint when you stand up, blurred vision, unusual fatigue, or nausea. These can signal that your blood pressure is dropping too low when your body changes position. The clinical term for this is orthostatic hypotension, defined as a drop of at least 20 points systolic or 10 points diastolic within three minutes of standing up. If you feel dizzy when you get out of bed but your seated reading looks fine, the issue may be positional rather than your resting number.
Getting an Accurate Reading
If you took this reading at home, a few factors can shift the result by several points in either direction. Sit with your back supported and feet flat on the floor for about five minutes before measuring. Rest your arm on a flat surface at heart level. Don’t measure right after exercise, caffeine, or a meal. Take two or three readings a minute apart and average them for the most reliable number.
A single reading is a snapshot, not a diagnosis. Blood pressure fluctuates throughout the day based on activity, stress, hydration, and even the temperature of the room. If you’re curious whether 106/63 represents your true baseline, take readings at the same time of day over a week or two. The pattern matters more than any single measurement.
What This Reading Means Long Term
For most adults, a resting blood pressure around 106/63 is close to ideal. It means your heart isn’t working harder than it needs to, and your blood vessels aren’t under excess pressure. Over time, maintaining readings in the normal range significantly reduces your risk of heart disease, stroke, and kidney damage compared to people with readings in the elevated or hypertensive categories. There’s nothing you need to “fix” about this number. The goal is simply to keep it where it is through the usual channels: staying active, eating a balanced diet, managing stress, and limiting sodium and alcohol.
