Several lifestyle changes can meaningfully lower your blood pressure, some by as much as 8 to 10 points on the systolic (top number) reading. The 2025 guidelines from the American Heart Association define Stage 1 hypertension as 130 to 139 systolic or 80 to 89 diastolic, and Stage 2 as 140/90 or higher. If your numbers fall in either range, the strategies below can help bring them down, whether you’re trying to avoid medication or working alongside it.
Isometric Exercise May Be the Most Effective Option
Exercise is one of the most reliable ways to lower blood pressure, but not all types are equal. A large meta-analysis in the British Journal of Sports Medicine compared aerobic exercise, resistance training, and isometric exercise (holding a static position without moving the joint). Isometric training came out on top, reducing systolic blood pressure by an average of 8.24 points and diastolic by 4 points. That’s nearly double the effect of aerobic exercise, which lowered systolic pressure by about 4.5 points.
The single most effective exercise studied was the isometric wall squat, sometimes called a wall sit. People who practiced wall sits saw systolic drops of about 10.5 points and diastolic drops of 5.3 points. Running was the most effective submode for lowering diastolic pressure specifically. A practical approach is to combine both: regular cardio like brisk walking or jogging for overall cardiovascular health, plus a few minutes of wall sits several times a week for the added blood pressure benefit.
Cutting Sodium, Adding Potassium
The World Health Organization recommends a maximum of 2 grams of sodium per day (about 5 grams of salt, or roughly one teaspoon). Most people consume well above that. For every meaningful reduction in daily sodium, systolic blood pressure drops about 1 point. That sounds modest, but sodium reduction compounds with other changes, and the effect is larger in people who start with higher intakes.
Potassium works as sodium’s counterpart. Both are electrolytes that help regulate fluid balance and blood volume. When potassium intake is adequate, your body excretes sodium more efficiently. The easiest way to shift the balance is to eat more fruits, vegetables, beans, and potatoes while cutting back on processed and packaged foods, which account for most dietary sodium. You don’t need a supplement for potassium in most cases. The food sources provide it in the amounts and forms your body handles best.
Lose Weight, Even a Little
Weight loss has one of the most consistent and well-documented effects on blood pressure. A meta-analysis published by the American Heart Association found that for every kilogram (about 2.2 pounds) of weight lost, systolic blood pressure drops roughly 1 point and diastolic drops about 0.9 points. Lose 10 pounds and you’re looking at a potential 4 to 5 point systolic reduction. The benefit comes from the weight loss itself, regardless of the specific diet used to achieve it.
Breathing Exercises and Stress Reduction
Slow, deep breathing directly influences blood pressure by calming the sympathetic nervous system, the part of your nervous system responsible for the “fight or flight” response. Practicing slow breathing for about 15 minutes a day can produce noticeable reductions.
One particularly well-studied technique is inspiratory muscle strength training, which involves breathing in against resistance using a small handheld device. A study published in the Journal of the American Heart Association found that doing just 30 resisted breaths per day, six days a week, lowered systolic blood pressure by an average of 9 points within six weeks. That’s comparable to what many people achieve with a first-line blood pressure medication. Even without the device, slow diaphragmatic breathing at a rate of about six breaths per minute for 15 minutes daily has shown benefits.
Sleep More Than Six Hours
Short sleep is an underappreciated driver of high blood pressure. Among people studied with sleep disorders, sleeping five to six hours per night increased the odds of hypertension by 45%. Sleeping fewer than five hours raised it by 80%. The American Heart Association considers short sleep, generally defined as six hours or less, a risk factor for hypertension based on strong epidemiological evidence. In fact, extremely short sleep duration was more harmful for blood pressure than the sleep disorder itself, suggesting that total hours of sleep matter enormously.
If you consistently sleep under seven hours and have elevated blood pressure, improving sleep may be one of the highest-impact changes you can make. Keeping a consistent wake time, limiting caffeine after midday, and keeping your bedroom cool and dark are straightforward starting points.
Alcohol: Less Is Better
Alcohol raises blood pressure in a dose-dependent way, meaning the more you drink, the higher the effect. Current guidance from the Mayo Clinic suggests up to one drink per day for women and up to two for men as the threshold for maintaining healthy blood pressure. If you regularly exceed those limits, cutting back can produce a measurable drop within weeks. For people who drink heavily, the blood pressure benefit of reducing alcohol can rival that of medication.
Magnesium Supplementation
Magnesium plays a role in blood vessel relaxation, and supplementation has been studied extensively. A meta-analysis published by the American Heart Association reviewed trials using doses ranging from about 80 to 637 milligrams of elemental magnesium daily, with a median dose of 365 milligrams over a typical 12-week period. The results varied significantly by form. Magnesium chloride produced the strongest reductions: about 6.3 points systolic and 5 points diastolic. Other commonly available forms like magnesium oxide showed no statistically significant effect on blood pressure.
Interestingly, higher doses didn’t produce greater reductions. The benefit appeared to be relatively constant across dosage levels, suggesting that the form of magnesium matters more than the amount. If you’re considering supplementation, magnesium chloride has the best evidence behind it for blood pressure specifically.
Dark Chocolate and Cocoa Flavanols
Cocoa contains compounds called flavanols that help blood vessels relax and dilate. But the dose needed for a real blood pressure effect is higher than most people assume. While the European Food Safety Authority recommends 200 milligrams of cocoa flavanols per day (achievable from about 10 grams of high-flavanol dark chocolate), research suggests that meaningful blood pressure reductions require closer to 900 to 1,000 milligrams of flavanols daily. In one trial, only the group consuming 1,052 milligrams per day saw significant results: a 5.3 point drop in systolic and a 3 point drop in diastolic pressure over six weeks.
That’s a lot more than a small square of dark chocolate provides. High-flavanol cocoa powder or concentrated cocoa supplements are more realistic ways to reach those levels. Standard dark chocolate bars, even those labeled 70% or higher, vary widely in flavanol content because processing destroys much of it.
Watch the Sodium in Your Water
One lesser-known factor is sodium in drinking water. Research published by the American Heart Association found that for each 100 milligrams per liter increase in water salinity, systolic blood pressure rose by 4.5 points and diastolic by 3.3 points. That same increase tripled the risk of developing Stage 1 or Stage 2 hypertension. Your gut detects the salt concentration of what you drink and signals the brain to adjust nervous system activity and blood pressure accordingly. If you live in an area with high-sodium tap water or you drink mineral water, checking the sodium content on the label is worth the effort. Sodium from water bypasses the usual awareness people have about salt in food.
