You just sat down in that crinkly paper-covered chair, the nurse cinched the Velcro cuff around your arm, and the machine whirred to life. The numbers pop up: 110 over 70. Most people see those digits and feel a wave of relief, but then you start wondering. Is it actually too low? Is it perfect?
Honestly, it's a great spot to be in.
When you ask is 110/70 a good blood pressure, you’re looking at what the American Heart Association (AHA) and most cardiologists consider "Ideal." It’s comfortably below the 120/80 threshold that marks the beginning of the "Elevated" category. You aren't just passing the test; you're basically an honors student in the world of cardiovascular health.
The Breakdown of 110 over 70
Blood pressure isn't just one number because your heart is a pump that works in cycles. The top number, 110, is your systolic pressure. That’s the force against your artery walls when your heart beats. The bottom number, 70, is your diastolic pressure—the pressure when your heart is resting between those beats.
Think of it like a garden hose. If you turn the spigot on full blast, the pressure is high. If you turn it down, it’s lower. 110/70 means your "pump" is moving blood with plenty of force to reach your brain and toes, but not so much force that it’s scarring your arteries or wearing out your heart muscle.
According to the 2017 ACC/AHA guidelines, anything under 120/80 is "Normal." But "Normal" is a broad range. If you were at 90/60, you might feel dizzy. If you were at 135/85, you’d be venturing into Stage 1 Hypertension territory. 110/70 is that "sweet spot" many athletes and healthy adults naturally maintain.
Why 110/70 is better than 120/80
For decades, we were told 120/80 was the gold standard. We practically memorized it. But medicine changes as we get better data.
The SPRINT trial (Systolic Blood Pressure Intervention Trial), a massive study funded by the National Institutes of Health, changed the game. It showed that for many people, especially those at higher risk for heart disease, aiming for a systolic pressure below 120 (like your 110) significantly reduced the risk of cardiovascular events and death compared to aiming for 140.
Basically, if your body naturally sits at 110/70 without medication, your blood vessels are likely flexible and clear. Your heart doesn't have to work overtime. You're giving your kidneys, brain, and eyes a break from the constant pounding of high-pressure blood flow.
Can it ever be too low?
Context matters.
If you feel great, 110/70 is fantastic. However, if you're a 90-year-old grandmother who feels faint every time she stands up, or if you're an athlete who suddenly dropped from 130/80 to 110/70 while feeling exhausted, a doctor might take a second look.
True hypotension (low blood pressure) usually isn't diagnosed by a specific number alone, but by symptoms. If you aren't experiencing dizziness, blurred vision, or fainting, 110/70 isn't "low"—it's efficient.

Factors that keep you in the 110/70 range
Nobody just "gets" a perfect reading by accident forever. It’s usually a mix of genetics and lifestyle.
If you're seeing 110/70 on your home monitor, you’re probably doing a few things right. Maybe you're hitting that 150 minutes of moderate exercise a week. Or perhaps your diet isn't loaded with the hidden sodium found in processed deli meats and canned soups.
Sodium is a huge factor here. It makes your body hold onto water, which increases the volume of your blood. More fluid in the same size "pipes" means higher pressure. By staying around 110/70, your salt-to-potassium balance is likely in a pretty good place.
Potassium is the unsung hero. It helps your blood vessels relax. Foods like bananas, spinach, and sweet potatoes are basically natural "anti-pressure" meds.
The "White Coat" effect and 110/70
Sometimes people get a 110/70 reading at home but a 135/85 at the doctor’s office. This is "White Coat Hypertension." Your nervous system kicks into high gear because you're in a clinical setting.
If your home average is 110/70, trust that more than a single high reading at the clinic. The most accurate way to know your "true" number is to take it at the same time every day—maybe right after you wake up—and keep a log.
Make sure you’re sitting correctly when you check. Feet flat on the floor. Back supported. Arm at heart level. No talking. If you're scrolling through stressful work emails while the cuff is squeezing, you might see 125/82. Put the phone down, breathe, and you'll likely see that 110/70 return.

Real-world risks of ignoring the numbers
High blood pressure is called the "silent killer" for a reason. You don't feel it. It doesn't hurt. But over years, it causes tiny tears in your artery walls. Your body tries to fix these tears with plaque, which narrows the arteries.
This leads to:
- Strokes: When a clot blocks blood to the brain or a vessel bursts.
- Heart Attacks: When the heart muscle can't get enough oxygen.
- Kidney Disease: The tiny filters in your kidneys are extremely sensitive to pressure.
- Vision Loss: High pressure can damage the delicate vessels in your retinas.
By having a reading of 110/70, you are actively avoiding this damage. You're keeping your "pipes" smooth and your organs well-perfused without the trauma of high-velocity flow.
Is 110/70 good for everyone?
Age changes things.
As we get older, our arteries naturally stiffen. It’s a process called arteriosclerosis. Because of this, it’s much harder for an 80-year-old to maintain 110/70 than it is for a 20-year-old.
In fact, some doctors are a bit more relaxed with older patients. If a senior's blood pressure is too low, they might fall, which is a huge risk. But even then, 110/70 is generally seen as a sign of excellent vascular health regardless of age, provided there’s no lightheadedness involved.
Pregnancy is another outlier. During pregnancy, your circulatory system expands rapidly, and blood pressure often drops. A reading of 110/70 is usually very healthy for an expectant mother, but doctors watch it closely because sudden spikes can signal preeclampsia.
What you should do next
If you've confirmed your blood pressure is 110/70, the goal is maintenance. You don't need to change your life to "fix" a number that isn't broken.

Keep doing the "boring" stuff. Walk. Eat your greens. Watch the salt. Most importantly, keep tracking it occasionally. Blood pressure isn't a static thing; it's a moving target. It changes with stress, sleep, and even the weather.
If you see it start to creep up consistently—say, hitting 125/80 for a few weeks—that's your signal to tighten up the diet or talk to a professional. But for now? 110/70 is a "win." You’ve got the kind of numbers that keep cardiologists happy and keep your heart beating strong for the long haul.
Actionable Steps to Maintain 110/70:
- Monitor at home twice a month. Don't become obsessed, but stay aware. Use a validated arm cuff monitor, not a wrist one, as wrist monitors are notoriously finicky.
- Focus on Magnesium and Potassium. These minerals are natural vasodilators. Reach for pumpkin seeds, almonds, and leafy greens.
- Manage "Hidden" Stress. Even if you feel fine, chronic high cortisol can slowly nudge those numbers up. Try five minutes of box breathing if you’ve had a rough day at work.
- Stay Hydrated. Dehydration can actually cause blood pressure to fluctuate wildly. Drinking enough water helps maintain consistent blood volume.
- Limit Alcohol. More than a drink or two a day is one of the fastest ways to see your 110/70 turn into a 135/90.
By sticking to these basics, you're not just celebrating a good number today—you're protecting your future self from the complications that come with hypertension.
