118/74 Blood Pressure: Is It Normal for Your Age?

A blood pressure of 118/74 is a good reading. It falls squarely in the “normal” category under current guidelines from the American Heart Association and the American College of Cardiology, which define normal blood pressure as below 120/80 mmHg. This applies to all adults regardless of age.

Where 118/74 Falls on the Chart

The 2025 AHA/ACC guidelines break adult blood pressure into four 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

At 118/74, both your top number (systolic) and bottom number (diastolic) sit comfortably inside the normal range. If those two numbers fell into different categories, you’d be classified in the higher one. In your case, both numbers agree: normal.

What the Two Numbers Mean

The top number, 118, measures the pressure in your arteries when your heart contracts and pushes blood out. The bottom number, 74, measures the pressure between beats, when your heart is relaxed and refilling. Together they give a picture of how much force your blood exerts against your artery walls throughout the cardiac cycle.

Cardiovascular risk starts rising at around 115/75 and roughly doubles with each jump of 20/10 mmHg above that point. At 118/74, you’re sitting just a few points above that baseline, which is about as low-risk as it gets.

Does Age Change the Interpretation?

It doesn’t. Older guidelines used different thresholds for people over 65, previously setting the hypertension cutoff at 150/80 for that age group. The current guidelines eliminated that distinction. All adults are now evaluated on the same scale, so 118/74 is considered normal whether you’re 25 or 75.

For pregnant women, the same classification applies. Normal blood pressure during pregnancy is below 120/80, and gestational hypertension isn’t diagnosed until readings reach 140/90 or higher after 20 weeks. A reading of 118/74 during pregnancy is reassuring.

Make Sure Your Reading Is Accurate

A single reading can be thrown off by surprisingly small things. Caffeine, alcohol, or exercise within 30 minutes of a measurement can push your numbers higher than they actually are. Even crossing your legs or letting your arm hang at your side instead of resting on a table can inflate the result. Talking during the reading, a full bladder, or a cuff placed over clothing can all skew things too.

For the most reliable number, sit in a comfortable chair with your back supported for at least five minutes beforehand. Keep both feet flat on the floor, rest your arm on a table at chest height, and place the cuff snugly against bare skin. Don’t eat, drink, or smoke for 30 minutes before measuring. If you’re checking at home, take two or three readings a minute apart and average them.

One good reading is encouraging, but a pattern of good readings over time is what really matters. Blood pressure fluctuates throughout the day based on stress, activity, and even the time of day.

Keeping Your Blood Pressure in the Normal Range

Since 118/74 is already normal, the goal is maintaining it rather than lowering it. The same habits that treat high blood pressure also prevent it from developing in the first place.

Regular aerobic exercise is one of the most effective tools. Aim for at least 30 minutes of moderate activity most days. Walking, cycling, swimming, and dancing all count. Adding strength training at least two days a week provides additional benefit. In people with high blood pressure, regular exercise alone can lower readings by 5 to 8 mmHg, and it’s similarly protective for keeping normal numbers stable over the years.

Diet plays an equally large role. Eating patterns rich in whole grains, fruits, vegetables, and low-fat dairy, while limiting saturated fat and sodium, can reduce blood pressure by up to 11 mmHg. The DASH diet and the Mediterranean diet are two well-studied versions of this approach. Potassium is particularly helpful because it counteracts the blood-pressure-raising effects of sodium. Getting 3,500 to 5,000 mg of potassium daily from foods like bananas, potatoes, beans, and leafy greens can lower blood pressure by 4 to 5 mmHg. On the sodium side, staying under 1,500 mg per day is ideal for most adults, though under 2,300 mg is a reasonable starting target.

These numbers may sound like they only matter for people with hypertension, but the protective effect is cumulative. Maintaining these habits now is what keeps 118/74 from gradually drifting into the elevated or stage 1 range over the next decade.
