You can lower high blood pressure through a combination of dietary changes, regular exercise, stress reduction, and, when needed, medication. Most people see measurable improvements within weeks of making lifestyle changes, and stacking several strategies together produces the largest drops. Normal blood pressure is below 120/80 mmHg. Stage 1 hypertension starts at 130/80, and Stage 2 begins at 140/90.
Cut Sodium and Increase Potassium
Sodium is the single most impactful dietary target. The World Health Organization recommends staying under 2,000 mg of sodium per day, which works out to just under a teaspoon of table salt. Most people consume well above that, largely from processed and restaurant foods rather than the salt shaker at home. Bread, deli meats, canned soups, frozen meals, sauces, and cheese are among the biggest hidden sources.
Reducing sodium works especially well when paired with the DASH diet, a pattern built around fruits, vegetables, whole grains, lean protein, and low-fat dairy. In the landmark DASH-Sodium trial funded by the National Heart, Lung, and Blood Institute, combining the DASH diet with low sodium intake reduced systolic blood pressure (the top number) by an average of 8.9 mmHg. Even at higher sodium levels, the DASH diet alone dropped systolic pressure by about 5.9 mmHg. Those are meaningful reductions, comparable to what some medications achieve.
Potassium plays a balancing role against sodium. It helps your body regulate fluid and blood volume, and most Americans don’t get enough of it. Good sources include bananas, potatoes, sweet potatoes, spinach, beans, yogurt, and avocados. If you have kidney disease, check with your provider before significantly increasing potassium, since your kidneys may not clear it efficiently.
Get at Least 150 Minutes of Exercise Per Week
Aim for at least 150 minutes of moderate aerobic activity per week, or 75 minutes of vigorous activity. Walking, cycling, swimming, dancing, and even active gardening all count. The key is raising your heart rate consistently, not choosing a specific sport. A combination of aerobic exercise and weight training appears to provide the greatest heart-health benefits, so adding two sessions of resistance work per week is worth considering.
You don’t need to do it all at once. Spreading activity across the week in 20- to 30-minute sessions works just as well. Blood pressure often starts to drop within a few weeks of regular exercise, and the effect continues as long as you maintain the habit. If you’ve been sedentary, starting with brisk walking is a practical first step that requires no equipment or gym membership.
Lose Weight If You’re Carrying Extra
Excess weight forces your heart to work harder with every beat. A meta-analysis of 25 studies found that every kilogram of body weight lost (about 2.2 pounds) corresponds to roughly a 1 mmHg drop in blood pressure. Some studies have shown reductions as high as 3 mmHg per kilogram lost. That means losing 10 pounds could lower your systolic reading by 4 to 6 points on its own, and the benefit compounds with other lifestyle changes.
You don’t need to reach an “ideal” weight to see results. Even modest weight loss of 5 to 10 percent of your body weight can produce a clinically meaningful difference in blood pressure. The method matters less than consistency: any sustainable approach to eating fewer calories or burning more energy will help.
Manage Stress With Structured Practices
Chronic stress keeps your body in a state that narrows blood vessels and raises heart rate. While occasional stress is unavoidable, how you respond to it can influence your blood pressure over time. An American Heart Association study tested a structured mindfulness program that included weekly group sessions, meditation, self-awareness exercises, and daily practice of about 45 minutes. Participants in the mindfulness group saw their systolic blood pressure drop by an average of 5.9 mmHg, compared to just 1.4 mmHg in the control group. They also reduced sedentary sitting by nearly six hours per week, which likely contributed to the benefit.
You don’t need to follow that exact protocol to gain something. Regular deep breathing, meditation apps, yoga, or simply building recovery time into your week can help. The underlying principle is shifting your nervous system out of its “fight or flight” mode more often throughout the day.
Limit Alcohol
Alcohol raises blood pressure both acutely and over time with regular use. The American Heart Association recommends no more than two drinks per day for men and one for women. A “drink” means 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of spirits. If you’re already above these limits, cutting back is one of the simpler changes that produces relatively fast results, often within days to weeks.
Consider Magnesium-Rich Foods or Supplements
Magnesium helps blood vessels relax, and low magnesium levels are common. A large meta-analysis of randomized controlled trials found that magnesium supplementation lowered systolic blood pressure by about 2.8 mmHg and diastolic by about 2 mmHg on average. The effect was more pronounced in people who were already low in magnesium, with systolic drops of nearly 6 mmHg. People already taking blood pressure medication who added magnesium saw the largest reductions: roughly 7.7 mmHg systolic.
Before reaching for a supplement, try increasing dietary magnesium through dark leafy greens, nuts, seeds, legumes, and whole grains. These foods also deliver potassium and fiber, reinforcing the overall dietary pattern that lowers blood pressure.
When Medication Becomes Necessary
Lifestyle changes are the foundation, but many people with Stage 1 or Stage 2 hypertension also need medication, particularly if their readings stay elevated after several months of consistent effort. Four main classes of drugs are used as first-line treatment. Diuretics help your kidneys flush extra fluid and salt. ACE inhibitors and ARBs both work by blocking a hormone that constricts blood vessels, just at different points in the process. Calcium channel blockers relax the muscles lining your blood vessel walls.
Your provider will typically start with one medication and adjust from there. It’s common to try a couple of options before finding the right fit, since side effects vary by person. Some people eventually need two or three medications working together, especially if their blood pressure started well above target. Medication works best as an addition to lifestyle changes, not a replacement for them.
Check for Underlying Causes
If your blood pressure stays high despite medication and lifestyle changes, an underlying condition could be driving it. Sleep apnea is one of the most common culprits. Studies show that obstructive sleep apnea is present in roughly 82% of people with resistant hypertension, the kind that doesn’t respond to standard treatment. Symptoms include loud snoring, waking up gasping, and persistent daytime fatigue. Treating sleep apnea with a breathing device worn at night often brings blood pressure down significantly.
Other possible causes include thyroid disorders, kidney disease, and adrenal gland problems. If you’re doing everything right and your numbers aren’t budging, it’s worth asking for further evaluation rather than simply adding another medication.
Monitor Your Blood Pressure at Home
Home monitoring gives you a more accurate picture than occasional office visits, since blood pressure fluctuates throughout the day and often spikes in clinical settings (a phenomenon called “white coat hypertension”). Use a validated upper-arm cuff rather than a wrist monitor. Before each reading, sit in a comfortable chair with your back supported for at least five minutes. Keep both feet flat on the floor with legs uncrossed, and rest your arm with the cuff on a table at chest height.
Take two readings about a minute apart, morning and evening, and record the results. Tracking trends over days and weeks is far more useful than reacting to any single reading. Share your log with your provider so they can make more informed decisions about treatment.
