A blood pressure of 104/62 mmHg is a good reading. It falls well within the normal category, which the American Heart Association defines as below 120/80 mmHg. Both your top number (104) and bottom number (62) sit comfortably under those thresholds, meaning your heart and blood vessels are working efficiently without excessive force.
What the Two Numbers Mean
The top number (104) is your systolic pressure, the force in your arteries each time your heart beats and pushes blood out. The bottom number (62) is your diastolic pressure, the force in your arteries between beats, when your heart is resting and refilling. Both numbers matter, and both of yours are in a healthy range.
Where 104/62 Falls on the Scale
The 2025 guidelines from the American Heart Association and American College of Cardiology break adult blood pressure into four categories:
- Normal: below 120 systolic and below 80 diastolic
- 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
At 104/62, you’re not just normal. You’re on the lower, more favorable end of normal. A large 2015 study found that keeping systolic pressure around or below 120 significantly reduced the risk of heart attacks and strokes. Research published in Nature Medicine also linked blood pressure below 130/80 to a 16% reduction in cognitive impairment and a lower risk of dementia. In other words, readings like yours are associated with long-term protection for both your heart and your brain.
Is 104/62 Too Low?
Some people see a number like 104/62 and worry it might be on the low side. There is no fixed cutoff where blood pressure becomes “too low.” Most health professionals only consider blood pressure problematically low if it causes symptoms. What counts as low for one person can be perfectly fine for another.
If you feel fine at 104/62, there’s nothing to be concerned about. But if you regularly experience dizziness, lightheadedness, blurred vision, fainting, fatigue, or trouble concentrating, those could be signs your pressure is dropping too low for your body. A sudden drop of just 20 mmHg can be enough to make you feel faint, even if the final number still looks “normal” on paper. The change matters as much as the number itself.
Who Typically Runs This Low
Readings in the low-normal range are common in younger adults, women, and people who exercise regularly. Research on adult athletes shows their resting blood pressure tends to run a few points lower than non-athletes, with female athletes averaging around 116/75 and endurance or speed-sport athletes trending even lower. Regular physical activity reduces resting blood pressure by about 3 to 4 mmHg on average.
Blood pressure also dips during pregnancy, particularly in the first and second trimesters, before rising again closer to delivery. Normal blood pressure during pregnancy is defined the same way: 120/80 or lower. A reading of 104/62 during pregnancy is not unusual and generally not a concern on its own.
Making Sure Your Reading Is Accurate
A single reading can be misleading. Blood pressure fluctuates throughout the day based on stress, caffeine, meals, hydration, and even how you’re sitting. If you’re measuring at home, the CDC recommends a few steps to get a reliable number:
- Timing: Avoid eating, drinking, or exercising for 30 minutes beforehand. Empty your bladder first.
- Position: Sit with your back supported and both feet flat on the floor, legs uncrossed, for at least five minutes before measuring.
- Cuff placement: Rest your arm on a table at chest height. The cuff should sit against bare skin, snug but not tight.
- Silence: Don’t talk during the reading.
- Repeat: Take at least two readings one to two minutes apart and note both.
If your two readings differ by more than a few points, the average of the two gives you a better picture. Tracking your blood pressure over several days or weeks is more meaningful than any single measurement.
The Bottom Line on 104/62
This reading places you in the normal, heart-healthy range with no indication of elevated risk. It’s the kind of number that cardiologists like to see. As long as you feel well and aren’t experiencing symptoms of low blood pressure, 104/62 is not just good. It’s excellent.
