How to Lower Blood Pressure
Lower blood pressure with less sodium, more potassium, regular exercise, less alcohol, and weight loss, and track the results with a home monitor.
High blood pressure is one of those things that feels abstract until a doctor tells you yours is too high. Then it suddenly feels very real.
About 48% of American adults have high blood pressure, on the CDC's survey data from August 2021 to August 2023. It usually produces no symptoms at all. That is why it is called the silent killer. It quietly damages blood vessels, strains the heart, and increases the risk of stroke and heart attack over years.
You will end up with a short list of daily changes, each with the size of its effect from the studies that measured it, and a home log that shows whether they are working for you. None of this replaces medication your doctor has prescribed.
Reduce your sodium intake
Cutting sodium lowers blood pressure directly, because less sodium means your body holds less water in your bloodstream. The recommended limit is 2,300 mg (roughly one teaspoon of table salt) and the ideal target for blood pressure is 1,500 mg. The tricky part is that most sodium does not come from your salt shaker. About 70% comes from processed foods, restaurant meals, and packaged items. Start reading nutrition labels. Canned soups, deli meats, bread, frozen meals, and condiments are surprisingly high. Cooking at home gives you direct control over sodium content. You do not need to go salt-free. Reading labels is how you find where it hides.
Move for 30 minutes on most days
Regular physical activity strengthens your heart so it can pump blood with less effort, which lowers the pressure on your arteries. Walking counts. Swimming counts. Cycling counts. Dancing in your kitchen counts. The specific activity matters less than the consistency. Aim for 150 minutes of moderate activity a week, about 30 minutes on 5 days. A 2013 review of 93 exercise trials found that endurance training such as brisk walking lowered systolic pressure by about 8 points in people with high blood pressure and about 2 points in people whose pressure was only slightly raised. You do not need to join a gym. A daily 30-minute walk at a pace where you can talk but not sing is moderate intensity. If you are starting from zero activity, begin with 10 to 15 minutes and add 5 minutes each week.
Increase your potassium intake
Potassium helps your kidneys flush out excess sodium. When potassium intake is low, your body retains more sodium, which raises blood pressure. Bananas get the credit, but gram for gram, sweet potatoes, cooked spinach, white beans, and avocados all carry more potassium, according to USDA's food composition data. Aim for 3,500 to 5,000 mg per day from whole foods, not supplements. Potassium supplements can be dangerous if you have kidney issues or take certain medications. Get it from food and your kidneys will self-regulate.
Limit alcohol consumption
The 2025 AHA and ACC hypertension guideline asks for abstinence, or no more than one drink a day for women and two for men. Abstinence is first in that sentence for a reason. The evidence points one way, which is that the less you drink the lower your pressure runs, so treat those numbers as a ceiling rather than a target. The size of the payoff depends on where you start. A 2017 review of 36 trials found that cutting back lowered blood pressure in people drinking more than two drinks a day, and that halving intake from six or more drinks a day lowered systolic pressure by about 5.5 points. One drink means 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of spirits. Restaurant pours are often larger than these standard sizes.
Good to know: At lighter drinking the effect is small but real. In the Japanese study behind the ACC release linked above, men who stopped drinking one to two drinks a day saw their systolic pressure fall by about 1 point, and women by a little less.
Manage chronic stress
Chronic stress keeps your sympathetic nervous system activated, maintaining elevated levels of cortisol and adrenaline. These hormones constrict blood vessels and raise heart rate, both of which increase blood pressure. Build regular practices that activate your parasympathetic nervous system, such as slow breathing (4 seconds in, 7 seconds hold, 8 seconds out), meditation, yoga, time outdoors, and enough sleep. Do one of them every day. The evidence behind stress practices is thinner than for the sodium, exercise, and weight steps, so use this step alongside those, not instead of them.
Maintain a healthy weight
Blood pressure increases with body weight. A 2003 analysis of weight-loss trials in the journal Hypertension found systolic pressure fell by about 1 point for every kilogram (2.2 pounds) lost, and by about 2.7 points on average in trials where people lost less than 5 kilograms (11 pounds). You do not need to reach a "perfect" weight to see a change. Focus on sustainable changes rather than crash diets. A moderate caloric deficit of 300 to 500 calories daily produces steady, maintainable weight loss of up to about 1 pound per week.
Monitor your blood pressure at home
Buy an upper-arm blood pressure monitor. Wrist monitors are less accurate. Take readings at the same time each day, ideally in the morning before coffee or exercise. Sit quietly for 5 minutes first with your arm supported at heart level. Take two readings 1 minute apart and average them. Record the numbers in a log or phone app. This data shows trends that a single doctor's office reading cannot reveal. It also reveals "white coat hypertension," where blood pressure spikes just from being in a medical setting.
Pick the two or three steps that fit your life most easily, start them this week, and add the others once they stick. Track your numbers at home and judge by the average over weeks, not any single reading. Bring your home log to your next appointment, because it shows your doctor your pressure outside the office. If your home average stays at 130/80 or higher, the stage 1 line in the FAQs below, tell your doctor rather than waiting for your next routine visit.

Questions we get asked about this
Answers from experience, not a textbook.
Normal is below 120/80 mmHg. Elevated is 120 to 129 systolic with less than 80 diastolic. Stage 1 hypertension is 130 to 139 systolic or 80 to 89 diastolic. Stage 2 hypertension is 140 or higher systolic or 90 or higher diastolic. These ranges come from the American Heart Association. A single high reading does not mean you have hypertension. Diagnosis requires consistently elevated readings over multiple visits or confirmed by home monitoring.
We could not find a published week-by-week timeline, so we will not invent one. The exercise trials in step 2 all lasted at least 4 weeks, and weight loss lowers pressure in step with the weight you lose (step 6). How much you see also depends on how high your pressure is to begin with. Check your home average every couple of weeks and bring the log to your doctor.
Never stop or reduce blood pressure medication without your doctor's guidance. Lifestyle changes can sometimes reduce or eliminate the need for medication, but that decision requires medical supervision. Stopping suddenly can cause a dangerous rebound spike. If your home readings are consistently improving, bring the data to your next appointment and discuss medication adjustment with your doctor.
In people with high blood pressure, a 2011 review in the American Journal of Clinical Nutrition found that 200 to 300 mg of caffeine raised systolic pressure by about 8 points on average, starting within the first hour and lasting at least 3 hours. After 2 weeks of regular coffee, the same review found no rise. Current research suggests that moderate coffee consumption (3 to 4 cups daily) does not cause long-term blood pressure increases in most people. If your blood pressure is already high, cut back for 2 weeks and compare your home average. Avoid caffeine before blood pressure readings for the most accurate numbers.
Both matter, but for different reasons. The top number (systolic) indicates the pressure when your heart beats and is a stronger predictor of cardiovascular risk, especially over age 50. The bottom number (diastolic) indicates pressure between beats and is more relevant for younger adults. Treatment guidelines now focus primarily on systolic pressure, but both numbers inform the overall picture.
