A blood pressure of 113/70 is a good reading. It falls squarely in the normal category, which the American Heart Association defines as below 120/80 mmHg. Both your numbers are comfortably within that range, so this reading is not a cause for concern.
Where 113/70 Falls on the Scale
Blood pressure is measured in two numbers. The top number (113 in your case) is systolic pressure, the force of blood pushing against artery walls when your heart beats. The bottom number (70) is diastolic pressure, measured between beats when the heart is refilling. Both numbers matter.
Here’s how the categories break down:
- 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
At 113/70, you’re in the normal range with room to spare. These thresholds apply to all adults regardless of age. The 2017 AHA/ACC guidelines eliminated the older, more lenient cutoffs that had previously been used for people over 65.
Is There Such a Thing as Too Low?
Normal blood pressure ranges from 90/60 up to 120/80. Your reading of 113/70 sits well above the lower boundary, so it’s not considered low. Hypotension, the medical term for low blood pressure, typically causes noticeable symptoms like dizziness, blurry vision, fainting, nausea, or unusual fatigue. If you feel fine, a reading on the lower end of normal is generally a sign of good cardiovascular health.
That said, diastolic pressure deserves a closer look. Research published in the Journal of the American College of Cardiology, drawing on over 11,000 adults tracked for three decades, found that diastolic readings between 60 and 69 mmHg were associated with a higher risk of subtle heart damage compared to readings of 80 to 89. At 70, your diastolic pressure sits right at the boundary, not in the concerning range. But if future readings consistently dip into the low 60s, it’s worth mentioning to your doctor, especially if you’re on blood pressure medication that could be pushing it lower than necessary.
One Reading Is a Snapshot, Not a Diagnosis
Blood pressure fluctuates throughout the day based on activity, stress, caffeine, and even the position of your arm. A single reading of 113/70 is encouraging, but a pattern of readings over days or weeks gives a much clearer picture of your cardiovascular health.
If you’re monitoring at home, accuracy depends on technique. The AHA recommends using an automatic, cuff-style monitor that wraps around your upper arm. Wrist and finger monitors give less reliable results. Before taking a reading, avoid caffeine, exercise, and smoking for at least 30 minutes, and empty your bladder. Sit quietly for five minutes with your feet flat on the floor and your arm supported at heart level. Take the reading over bare skin, not over clothing. It’s also a good idea to bring your home monitor to a doctor’s appointment once a year to verify it’s reading accurately against clinical equipment.
Taking two or three readings a minute apart and averaging them will give you a more stable number than relying on any single measurement.
How to Keep Your Numbers Where They Are
Maintaining normal blood pressure is easier than lowering it once it climbs. The same habits that protect against hypertension also benefit heart health broadly.
Diet plays a measurable role. The DASH eating pattern, which emphasizes fruits, vegetables, whole grains, and lean protein while limiting sodium, has been shown to lower systolic pressure by about 3 to 5 points and diastolic pressure by about 2 points on average. That effect is modest for someone already at 113/70, but it illustrates how dietary choices directly influence your numbers. Keeping sodium intake below 2,300 mg per day (and ideally closer to 1,500 mg) is one of the most impactful single changes for blood pressure.
Regular physical activity, maintaining a healthy weight, limiting alcohol, managing stress, and getting adequate sleep all contribute to keeping blood pressure in the normal range over the long term. These factors become increasingly important with age, since arteries naturally stiffen over time and systolic pressure tends to creep upward.
What This Reading Means for Your Risk
A blood pressure of 113/70 puts you in a favorable position for cardiovascular health. High blood pressure is a leading contributor to heart attack, stroke, kidney disease, and heart failure, and your numbers suggest none of that added risk. The closer your systolic pressure stays to the 110 to 120 range over the years, the lower your lifetime risk of these conditions.
Keep in mind that blood pressure is just one piece of the picture. Cholesterol levels, blood sugar, family history, smoking status, and physical activity all factor into overall cardiovascular risk. A normal blood pressure reading is genuinely good news, but it works best as part of a broader pattern of healthy habits.
