A blood pressure of 104/69 is a good reading. It falls squarely in the normal category, which is defined as a systolic (top number) below 120 and a diastolic (bottom number) below 80. You’re well within that range on both counts, and comfortably above the low blood pressure threshold of 90/60.
Where 104/69 Falls on the Chart
The 2025 guidelines from the American Heart Association and American College of Cardiology break blood pressure into these 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+ systolic or 90+ diastolic
At 104/69, both numbers sit in the normal range. The top number (systolic) reflects the pressure in your arteries when your heart beats. The bottom number (diastolic) measures the pressure between beats, when your heart is resting. Neither number needs to be closer to 120/80 to be “better.” In fact, lower within the normal range is generally associated with less strain on your blood vessels over time.
Why Some People Run on the Lower Side
A reading of 104/69 is common in younger adults, people who exercise regularly, and those with a naturally lean build. Endurance training, for example, lowers resting blood pressure through several mechanisms: blood vessels become more relaxed (reducing resistance by about 7%), resting heart rate drops, and the hormonal signals that constrict arteries quiet down. Trained athletes can show stress hormone levels roughly 29% lower than their untrained levels, which translates directly to lower resting pressure.
This doesn’t mean you need to be an athlete to have a reading of 104/69. Plenty of people sit at this level without any particular fitness routine. It simply reflects how their cardiovascular system operates at rest.
When a Lower Reading Could Be a Problem
Blood pressure is only considered too low when it drops below 90/60 or when it causes symptoms. At 104/69, you’re above that threshold. But if you regularly experience dizziness, lightheadedness, blurry vision, unusual fatigue, or fainting, those symptoms are worth paying attention to regardless of the number on the cuff. Older adults are particularly prone to drops in blood pressure when standing up or after meals, which can cause falls even when their seated reading looks fine.
The key distinction: blood pressure that’s low on paper but causes no symptoms is not a medical concern. It only becomes a problem when your organs aren’t getting adequate blood flow, which shows up as noticeable symptoms first.
Making Sure Your Reading Is Accurate
A single reading is a snapshot, not a diagnosis. Blood pressure fluctuates throughout the day based on stress, caffeine, hydration, posture, and even whether you’ve been talking. To get a reliable picture of where you actually sit, a few basics matter.
Sit quietly for five minutes before measuring. Keep your feet flat on the floor with legs uncrossed, and rest your arm on a surface so the cuff is level with your heart. A cuff that’s too small or too large will throw off the reading, sometimes by 10 points or more, so make sure yours fits your arm circumference. Taking two or three readings a minute apart and averaging them gives you a more trustworthy number than relying on a single measurement.
What to Expect as You Age
Systolic blood pressure tends to rise with age. Large arteries stiffen over time, and plaque gradually accumulates on vessel walls, both of which push the top number higher. Someone reading 104/69 in their twenties or thirties may see that creep toward 115 or 120 over the following decades, even with a healthy lifestyle. That’s a normal trajectory, and staying under 120/80 remains the goal at any age.
Keeping an eye on your numbers over the years, rather than fixating on any single reading, is the most useful habit. If your blood pressure is consistently normal and you have no symptoms, periodic checks at routine medical visits are sufficient to track any changes.
