Reducing high blood pressure is possible through a combination of dietary changes, regular exercise, weight management, and, when necessary, medication. Most people with stage 1 hypertension (130 to 139 systolic or 80 to 89 diastolic) can make meaningful progress with lifestyle changes alone. Stage 2 hypertension (140/90 or higher) typically requires medication alongside those same habits.
Rethink What You Eat
Diet is the single most impactful lifestyle change for blood pressure. The DASH diet (Dietary Approaches to Stop Hypertension) centers on fruits, vegetables, whole grains, lean protein, and low-fat dairy while cutting back on saturated fat and added sugar. In clinical trials, people with hypertension who followed the DASH diet with low sodium intake saw systolic blood pressure drop by about 11.5 mmHg. A large meta-analysis found average reductions of roughly 6.7 mmHg systolic and 3.5 mmHg diastolic. When the DASH diet was combined with a weight management program, systolic pressure dropped by over 16 mmHg.
Sodium is the other half of the equation. The American Heart Association recommends no more than 2,300 milligrams per day, with an ideal target of 1,500 mg for most adults who have high blood pressure. For context, a single teaspoon of table salt contains about 2,300 mg. Most excess sodium comes not from the salt shaker but from packaged foods, restaurant meals, bread, deli meats, canned soups, and condiments. Reading nutrition labels and cooking more at home are the most effective ways to cut your intake.
Potassium works as a natural counterbalance to sodium. When you eat more potassium-rich foods, your kidneys excrete more sodium in urine rather than reabsorbing it back into your bloodstream. Low potassium intake does the opposite: your body holds onto more sodium, which raises blood pressure. Good sources include bananas, potatoes, spinach, beans, avocados, and yogurt. If you have kidney disease, talk to your care team before increasing potassium significantly.
Move More, Consistently
Aim for at least 150 minutes of moderate aerobic activity per week, or 75 minutes of vigorous activity. That breaks down to about 30 minutes on most days, and you don’t have to do it all at once. Three 10-minute sessions provide the same benefit as one 30-minute session. Walking, swimming, cycling, dancing, and even yard work all count, as long as your heart rate and breathing rate go up.
A combination of aerobic exercise and strength training offers the most benefit for heart health. You don’t need a gym membership. Bodyweight exercises, resistance bands, or carrying groceries up stairs all build the kind of functional strength that supports healthy blood vessels. The key is consistency over intensity. A daily 20-minute walk does more for your blood pressure over time than a single intense weekend workout.
Lose Even a Small Amount of Weight
Every kilogram of weight lost (about 2.2 pounds) can reduce systolic blood pressure by 1 to 4 mmHg and diastolic by 1 to 2 mmHg. That means losing just 5 kilograms, roughly 11 pounds, could lower your systolic reading by 5 to 20 points. You don’t need to reach an “ideal” weight to see results. Even modest, sustained weight loss shifts blood pressure in the right direction, especially when combined with the dietary and exercise changes described above.
Limit Alcohol
Alcohol raises blood pressure both acutely and over time. Keeping intake moderate means no more than one drink per day for women and two for men. One drink equals 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of distilled spirits. Regularly exceeding these amounts can blunt the effectiveness of blood pressure medications and contribute to weight gain, compounding the problem.
Manage Stress and Protect Your Sleep
Chronic stress keeps your body in a state of heightened alertness, with elevated heart rate and constricted blood vessels. Mindfulness-based stress reduction has measurable effects: in a clinical trial of women with hypertension, an eight-week mindfulness program lowered systolic pressure by about 9 mmHg and diastolic by about 7 mmHg. Deep breathing exercises, meditation, and even regular time spent on hobbies you enjoy can help bring those stress responses down.
Sleep matters more than most people realize. Obstructive sleep apnea, where breathing repeatedly stops and restarts during sleep, is one of the most common and underdiagnosed causes of resistant hypertension. Each time breathing pauses, oxygen drops and the body triggers a surge of adrenaline-like activity. Over time, this doesn’t just spike blood pressure at night. It rewires the nervous system to keep blood vessels constricted around the clock, even during waking hours. If you snore heavily, wake up feeling unrested, or your partner has noticed you stop breathing during sleep, getting evaluated for sleep apnea could be the missing piece in controlling your blood pressure.
When Medication Is Needed
Lifestyle changes are powerful, but some people need medication to reach a safe blood pressure range, particularly those with stage 2 hypertension or additional risk factors like diabetes or kidney disease. Four main classes of drugs are used as first-line treatment, and each works differently:
- Diuretics help your kidneys flush out excess sodium and water, reducing the volume of fluid your heart has to pump.
- ACE inhibitors block a hormone pathway that tightens blood vessels, allowing arteries to relax and widen.
- Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels, which relaxes vessel walls and can slow heart rate.
- Beta-blockers reduce the effects of adrenaline on your heart, lowering both heart rate and the force of each heartbeat.
Most people start on one medication. If blood pressure doesn’t reach the target range, a second drug from a different class is often added because combining two mechanisms tends to work better than increasing the dose of a single drug. Finding the right medication or combination can take weeks or months of adjustments. Side effects vary by class, so if one medication causes problems like fatigue, dizziness, or a persistent cough, switching to another class usually resolves it.
Putting It Together
No single change works as well as several changes stacked together. Following the DASH diet can lower systolic pressure by 7 to 11 mmHg. Adding regular exercise, losing some weight, cutting sodium, and managing stress can each contribute additional points. Together, these changes can rival or even exceed the effect of a single blood pressure medication, which typically lowers systolic pressure by about 8 to 10 mmHg. For people already on medication, the same lifestyle changes often allow for lower doses or fewer drugs over time.
Blood pressure responds to sustained habits, not short bursts of effort. Most people see noticeable improvements within two to four weeks of consistent dietary and exercise changes, with continued progress over three to six months.
