A blood pressure of 104/72 is a good reading. It falls squarely in the “Normal” category, which the American Heart Association defines as anything below 120/80 mmHg. Both your top number (systolic) and bottom number (diastolic) are well within the healthy range, and this reading is associated with lower cardiovascular risk.
Where 104/72 Falls on the Chart
The most current blood pressure guidelines, updated in 2025 by the American Heart Association and American College of Cardiology, break adult blood pressure into five 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
- Severe Hypertension: above 180 systolic and/or above 120 diastolic
At 104/72, you’re 16 points below the threshold for “Elevated” on the top number and 8 points below on the bottom number. That gives you a comfortable margin. If your two numbers ever land in different categories, the higher category is the one that counts, but in your case both numbers point to the same result: normal.
Why This Reading Is Better Than “Just OK”
Not all normal readings are equal. A systolic pressure of 118 with a diastolic of 79 is technically normal too, but it sits right at the edge. Your reading of 104/72 is closer to the middle of the normal range, which is where cardiovascular risk is lowest. As systolic pressure rises, even within the normal range, the strain on artery walls increases gradually. Being well below 120 means less wear on your blood vessels over time.
These guidelines apply the same way regardless of age or sex. Earlier versions of the blood pressure guidelines used different thresholds for people over 65, but the current standards treat all adults the same. The reasoning: large clinical trials found that lower blood pressure targets benefited patients across age groups. So whether you’re 25 or 70, 104/72 is a healthy number.
Is 104/72 Too Low?
Some people worry that a reading in the low 100s might be a sign of low blood pressure, or hypotension. It isn’t. Clinically, low blood pressure is defined as a reading below 90/60 mmHg, and your numbers are well above that threshold. More importantly, most health professionals consider blood pressure “too low” only when it causes symptoms. The number alone rarely tells the whole story.
If you feel fine at 104/72, there is nothing to be concerned about. Some people naturally run on the lower end of normal and feel perfectly healthy. This is especially common in people who exercise regularly, since physical fitness tends to lower resting blood pressure.
Symptoms that would make a low-normal reading worth investigating include dizziness or lightheadedness (especially when standing up), fainting, blurred vision, unusual fatigue, or trouble concentrating. These can signal that your brain or organs aren’t getting enough blood flow, and they warrant a conversation with your doctor. But without symptoms, a reading of 104/72 is simply a sign that your cardiovascular system is working efficiently.
What Keeps Blood Pressure in This Range
Your blood pressure reflects two things happening simultaneously: how forcefully your heart pumps blood and how much resistance your arteries put up against that flow. The top number (systolic) captures the peak pressure when your heart contracts. The bottom number (diastolic) measures the pressure between beats, when your heart is relaxed and refilling.
A reading of 104/72 suggests your heart is pumping at a steady, moderate force and your arteries are relatively flexible and relaxed. As people age, arteries tend to stiffen and accumulate plaque, which pushes systolic pressure higher. Maintaining a healthy reading now, through regular activity, a balanced diet, and managing stress, helps protect that arterial flexibility for the future.
Making Sure Your Reading Is Accurate
A single blood pressure reading is a snapshot, not a diagnosis. If you took this measurement at home, it’s worth confirming you followed the right steps, since small errors can shift the numbers by 5 to 10 points in either direction.
For the most reliable home reading, use an upper arm cuff rather than a wrist monitor. Sit quietly for five minutes before measuring, with your back supported against a chair and both feet flat on the floor. Rest your arm on a table at heart level, and place the cuff on bare skin rather than over a sleeve. A rolled-up sleeve that’s tight around your arm can distort the result. Empty your bladder beforehand, since a full bladder can nudge your reading upward. Don’t talk during the measurement.
Taking two or three readings a minute apart and averaging them gives you a more reliable picture than relying on a single number. If your average consistently lands around 104/72, you can feel confident that your blood pressure is genuinely in a healthy range.
Keeping It There
Having normal blood pressure now doesn’t guarantee it stays that way. Blood pressure tends to creep upward with age, weight gain, increased sodium intake, and reduced physical activity. The lifestyle habits that matter most for keeping your numbers low are the ones you’ve probably heard before: regular aerobic exercise (even 30 minutes of brisk walking most days makes a measurable difference), limiting sodium to around 2,300 mg per day or less, maintaining a healthy weight, moderating alcohol, and managing stress.
Checking your blood pressure periodically, even when you feel fine, helps you catch any gradual upward trend before it crosses into the elevated or hypertensive range. A reading of 104/72 is a strong starting point, and it’s worth protecting.
