A blood pressure of 106/72 is a good reading. It falls squarely within the normal category, which the American Heart Association defines as a systolic (top number) below 120 and a diastolic (bottom number) below 80. Both of your numbers sit comfortably in that range.
Where 106/72 Falls on the Chart
Blood pressure is classified into five categories based on the top and bottom numbers together:
- 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
- Severe hypertension: above 180 systolic or above 120 diastolic
At 106/72, you’re not close to any of the thresholds for concern on the high end. If one number fell in a higher category than the other, your reading would be classified by whichever category is higher. In your case, both numbers land in normal, so the classification is straightforward.
What the Two Numbers Mean
The top number (106) is your systolic pressure, the force your blood exerts against artery walls each time your heart beats. The bottom number (72) is your diastolic pressure, the force between beats when your heart relaxes. Together, they give a picture of how hard your cardiovascular system is working. A reading of 106/72 means your heart is pumping efficiently without placing excess strain on your blood vessels.
Could 106/72 Be Too Low?
For most people, no. There is no firm numerical cutoff where blood pressure becomes “officially” too low. Most healthcare professionals consider blood pressure problematic only when it causes symptoms. Those symptoms include dizziness or lightheadedness, blurred or fading vision, fainting, fatigue, trouble concentrating, and nausea.
If you feel fine at 106/72, there’s nothing to worry about. Some people naturally run on the lower end and feel perfectly healthy. The concern arises when blood pressure drops suddenly. A shift of just 20 mmHg from your usual reading can cause dizziness or fainting, even if the resulting number looks “normal” on paper. So context matters: 106/72 as your steady baseline is healthy, but 106/72 as a sudden drop from your usual 130/85 could feel uncomfortable.
Does Age Change the Target?
The normal category (below 120/80) applies to adults of all ages. For older adults being treated for high blood pressure, clinical guidelines generally recommend a target below 130/80 for those at higher cardiovascular risk, and below 140/90 for those at lower risk. A reading of 106/72 is well below both of those treatment targets, which means it’s a healthy number for adults whether they’re 30 or 70. For older adults taking blood pressure medications, though, readings on the lower end sometimes warrant a conversation about whether medication doses need adjusting, particularly if dizziness or falls become an issue.
During Pregnancy
Blood pressure naturally dips during the first and second trimesters, so a reading of 106/72 during pregnancy is expected and not a red flag. High blood pressure in pregnancy is defined as 140/90 or higher on two separate readings at least four hours apart. Your reading is far from that threshold.
Making Sure Your Reading Is Accurate
A single reading is a snapshot, not a diagnosis. To get the most reliable number, the CDC recommends sitting in a comfortable chair with your back supported for at least five minutes before measuring. Keep both feet flat on the floor with your legs uncrossed, and rest your arm with the cuff at chest height on a table. The cuff should sit against bare skin, snug but not tight. Don’t talk during the measurement.
If you’re monitoring at home, take two or three readings a minute apart and average them. Blood pressure fluctuates throughout the day based on stress, caffeine, physical activity, and even a full bladder. A pattern over several days gives you a much clearer picture than any single reading. If your numbers consistently land in the range you’re seeing now, you’re in good shape.
