Most people can lower their blood pressure meaningfully through a combination of dietary changes, regular exercise, and a few key lifestyle shifts. Some of these changes can reduce your systolic pressure (the top number) by 5 to 8 points on their own, and stacking several together can rival the effect of medication. The specific strategies that work best depend on where your blood pressure sits right now and what’s driving it up.
Know Your Numbers First
Blood pressure falls into four categories based on the 2025 guidelines from the American Heart Association and American College of Cardiology:
- Normal: below 120/80
- Elevated: 120 to 129 systolic, with diastolic still under 80
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
If your systolic and diastolic numbers fall into different categories, the higher category is the one that applies. Knowing where you stand helps you gauge how aggressively you need to act. Someone with elevated pressure might bring it back to normal with diet alone. Someone in stage 2 territory will likely need multiple changes working together, and possibly medication as well.
Cut Back on Sodium
Reducing sodium is one of the most reliable ways to drop your blood pressure. In a clinical trial funded by the National Institutes of Health, participants who ate roughly 500 mg of sodium per day saw an average systolic drop of 6 points compared to their usual diet. Nearly three out of four people responded to the low-sodium diet, meaning this works for most people, not just a select few.
You don’t need to hit 500 mg to see results. The biggest gains come from moving away from the typical American intake of 3,400 mg per day toward something closer to 1,500 mg. Most of the sodium in your diet comes from packaged and restaurant food, not the salt shaker. Reading labels, cooking more at home, and choosing fresh or frozen vegetables over canned ones are the most practical starting points. Bread, deli meat, pizza, canned soup, and cheese are the biggest stealth sources.
Follow the DASH Eating Pattern
The DASH diet (Dietary Approaches to Stop Hypertension) is the most studied dietary pattern for blood pressure. It emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while limiting saturated fat, red meat, and added sugars. In clinical trials, people on the DASH diet had greater blood pressure reductions than those who simply added more fruits and vegetables to a typical American diet.
Combining DASH with low sodium intake produces bigger results than either approach alone. In the DASH-Sodium trial, the combination of the DASH diet with 1,500 mg of sodium per day lowered blood pressure more than any other combination tested. A later study called OmniHeart found that swapping about 10% of the carbohydrates in the DASH diet for either protein or unsaturated fat (think nuts, olive oil, avocado, or fish) improved results even further.
The practical takeaway: fill half your plate with fruits and vegetables, choose whole grains over refined ones, eat beans or fish several times a week, and use olive oil instead of butter. This pattern works partly because it’s naturally high in potassium, which directly counters sodium’s effect on blood pressure.
Get Enough Potassium
Potassium helps your body flush excess sodium through urine and relaxes blood vessel walls, both of which bring pressure down. The effect is strongest in people who are sensitive to salt. The recommended daily intake is 3,400 mg for men and 2,600 mg for women, but most Americans fall well short of that.
Good sources include bananas, potatoes, sweet potatoes, spinach, white beans, yogurt, salmon, and avocados. A single medium baked potato with the skin delivers about 900 mg. Getting your potassium from food rather than supplements is generally safer, since very high doses from pills can cause problems for people with kidney disease.
Exercise Regularly
Regular physical activity lowers both the top and bottom blood pressure numbers. Studies show reductions of 4 to 10 points systolic and 5 to 8 points diastolic, which is comparable to what some blood pressure medications deliver. The target is at least 150 minutes of moderate aerobic activity per week, or 75 minutes of vigorous activity. That breaks down to about 30 minutes of brisk walking five days a week.
You don’t need to do it all at once. Three 10-minute walks spread through the day count. Cycling, swimming, dancing, and even vigorous yard work all qualify. Resistance training (lifting weights, bodyweight exercises) also helps, though its effect on blood pressure is somewhat smaller than aerobic exercise. The combination of both is ideal. Consistency matters more than intensity. A person who walks every day will see more benefit than someone who runs hard once a week and sits the rest of the time.
Lose Weight If You Need To
Carrying extra weight forces your heart to pump harder, which raises blood pressure. A meta-analysis of randomized trials found that blood pressure drops by about 1 point systolic and 1 point diastolic for every kilogram (roughly 2.2 pounds) of weight lost. That means losing 10 pounds could reduce your systolic pressure by 4 to 5 points.
You don’t need to reach an ideal body weight to benefit. Even modest weight loss of 5 to 10% of your starting weight can make a noticeable difference. The PREMIER clinical trial showed that combining the DASH diet with increased physical activity produced the greatest reductions in both weight and blood pressure, which makes sense since the strategies reinforce each other.
Limit Alcohol
Drinking above moderate levels raises blood pressure and can blunt the effect of other lifestyle changes you’re making. The American Heart Association recommends no more than two drinks per day for men and one for women. One drink equals 12 ounces of regular beer, 5 ounces of wine, or 1.5 ounces of 80-proof liquor.
If you’re currently drinking more than these amounts, cutting back can produce a measurable drop in blood pressure within weeks. If you don’t drink, there’s no benefit to starting.
Sleep 7 to 8 Hours a Night
Sleep has a stronger connection to blood pressure than most people realize. Compared to sleeping 7 to 8 hours, regularly getting fewer than 6 hours per night is associated with a 36% to 66% higher risk of hypertension. But oversleeping isn’t protective either: averaging more than 9 hours is linked to an 11% to 30% increased hypertension risk. The sweet spot for the lowest hypertension rates is 7.5 to 8 hours.
Sleep regularity matters too. Going to bed and waking up at roughly the same time each day is associated with lower blood pressure independent of total sleep time. If you suspect sleep apnea (loud snoring, gasping during sleep, feeling exhausted despite enough hours in bed), getting it treated can significantly improve your blood pressure.
Supplements That May Help
A few natural supplements have enough clinical evidence to be worth considering, though none replaces the strategies above.
- Hibiscus tea: Drinking two teaspoons steeped daily has been linked to a systolic drop of about 7.5 points. It has a tart, cranberry-like flavor and is widely available.
- Cocoa flavanols: The compounds in dark chocolate can lower blood pressure by roughly 4.7 systolic and 2.8 diastolic points. About a quarter of a dark chocolate bar (look for 70% cocoa or higher) provides enough.
- Magnesium: At doses of 200 to 600 mg daily, magnesium is associated with a modest drop of about 2 systolic points. The effect is larger in people with chronic conditions. Many people are mildly deficient, so this can serve double duty.
How to Measure Accurately at Home
Tracking your blood pressure at home gives you a more reliable picture than occasional office visits, since many people’s readings spike in a clinical setting. To get accurate numbers, follow these steps from the CDC: don’t eat, drink, or exercise for 30 minutes beforehand. Empty your bladder. Sit with your back supported and both feet flat on the floor for at least 5 minutes before measuring. Rest the cuffed arm on a table at chest height, with the cuff against bare skin. Keep your legs uncrossed, and don’t talk during the reading.
Take at least two readings 1 to 2 minutes apart and average them. Measure at the same time each day, ideally morning and evening, and keep a log. A week or two of consistent readings is far more informative than any single measurement. These numbers are what you’ll want to share with your healthcare provider, and they’re a reliable way to see whether the changes you’re making are actually working.
