A blood pressure of 113/71 mmHg is a good reading. It falls squarely in the “normal” category, which both the American Heart Association and the American College of Cardiology define as below 120/80 mmHg. Both your top number (systolic) and bottom number (diastolic) are well within the healthy range, and well above the threshold for low blood pressure.
What 113/71 Means
The two numbers in a blood pressure reading measure different things. The top number, 113 in your case, is the systolic pressure: the force your blood exerts on artery walls when your heart beats. The bottom number, 71, is the diastolic pressure: the force between beats, when your heart is resting. Both numbers matter, and both of yours are in a healthy zone.
For context, here’s how the major categories break down:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic with diastolic still below 80
- Hypertension Stage 1: 130 to 139 systolic or 80 to 89 diastolic
- Hypertension Stage 2: 140 or higher systolic or 90 or higher diastolic
At 113/71, you’re not even close to the elevated range. This reading is considered ideal.
It’s Not Too Low, Either
Some people worry that a number like 113/71 might be on the low side. It isn’t. Low blood pressure, or hypotension, is generally defined as a reading below 90/60 mmHg. Your reading is comfortably above both of those thresholds.
That said, blood pressure that’s technically “normal” on paper can still cause symptoms if it represents a sudden drop from your usual level. A decrease of just 20 mmHg in systolic pressure, say from 110 down to 90, can cause dizziness or fainting. If you feel lightheaded, fatigued, or have trouble concentrating, those are worth mentioning to your doctor regardless of what the numbers say. Most healthcare professionals consider blood pressure too low only when it causes symptoms.
One Reading Isn’t the Whole Picture
Blood pressure fluctuates throughout the day. Caffeine, stress, poor sleep, and even body position can temporarily push your numbers up or down. Research has found that shorter sleep the night before a measurement and emotional stress both contribute to blood pressure variability. That’s why you’re typically advised to avoid caffeine and sit quietly for several minutes before taking a reading.
A single reading of 113/71 is reassuring, but what matters more is your pattern over time. If you’re checking at home, take readings at roughly the same time each day, sit with your feet flat on the floor, and rest for a few minutes first. A consistent pattern in the normal range is a stronger signal than any single measurement.
Does Age Change What’s “Good”?
For most adults, below 120/80 remains the definition of normal blood pressure regardless of age. Treatment thresholds do shift for older adults. Guidelines from the American Academy of Family Physicians recommend treating hypertension to a target below 140/90 for all adults, including those over 80. But when it comes to defining what’s healthy in someone without hypertension, 113/71 is a good number whether you’re 30 or 75.
Pregnancy is one situation where blood pressure targets and interpretation change significantly, so those readings are best discussed directly with an obstetrician.
How to Keep It This Way
If your blood pressure is already normal, the goal is to keep it there. The habits that matter most aren’t surprising, but the specifics are worth knowing. Aim for at least 30 minutes of moderate physical activity most days, plus strength training at least twice a week. On the diet side, keeping sodium below 2,300 mg per day is the general guideline, though closer to 1,500 mg per day is ideal for most adults. For reference, a single teaspoon of table salt contains about 2,300 mg of sodium, and most of the sodium people consume comes from processed and restaurant food rather than the salt shaker.
Maintaining a healthy weight, limiting alcohol, managing stress, and not smoking all contribute to long-term blood pressure stability. These aren’t just strategies for people with high blood pressure. They’re what keeps normal readings normal as you age, since blood pressure tends to creep upward over the years if left unchecked.
