What Can Help High Blood Pressure: Diet, Exercise & More

High blood pressure responds to a combination of lifestyle changes that, taken together, can lower your numbers significantly. For some people, these changes are enough on their own. For others, they work alongside medication to bring blood pressure into a safer range. The most effective approaches target weight, sodium intake, physical activity, alcohol, sleep, and stress, each contributing a few points of reduction that add up.

Lose Weight, Even a Little

Weight loss is one of the most reliable ways to lower blood pressure. A meta-analysis of 25 studies published in the American Heart Association’s journal found that every kilogram of weight lost (about 2.2 pounds) corresponds to roughly a 1 mmHg drop in blood pressure. Some studies have found even larger effects: closer to 3 mmHg per kilogram in men with high blood pressure who weren’t also restricting sodium.

That means losing 10 pounds could lower your systolic pressure (the top number) by 4 to 7 points. You don’t need to reach an ideal weight to see benefits. Even modest, sustained weight loss makes a measurable difference, and the effects tend to hold as long as the weight stays off.

Cut Sodium Below 2,300 mg Per Day

The Dietary Guidelines for Americans set the daily sodium limit at 2,300 milligrams for adults, which is about one teaspoon of table salt. Most people consume well above that. Reducing sodium lowers blood pressure by decreasing the volume of fluid your blood vessels have to handle, which eases pressure on artery walls.

The biggest sources of sodium aren’t the salt shaker. They’re processed and restaurant foods: bread, deli meats, canned soups, pizza, sandwiches, and sauces. Reading nutrition labels and cooking more meals at home are the most practical ways to get sodium under control. If your blood pressure is already elevated, getting closer to 1,500 mg per day may offer additional benefit, though that’s a harder target to sustain.

Increase Potassium Intake

Potassium works as a counterbalance to sodium. It helps your kidneys flush excess sodium out through urine, which reduces fluid volume and lowers blood pressure. The CDC notes that increasing potassium intake can help decrease blood pressure in people with hypertension and reduce the risk of heart disease and stroke.

Good sources include bananas, potatoes, sweet potatoes, spinach, beans, yogurt, and avocados. Most adults fall short of the recommended 2,600 to 3,400 mg per day. If you have kidney disease, talk with your doctor before significantly increasing potassium, since your kidneys may not handle the extra load well.

Consider Magnesium

Magnesium supplementation has a modest but real effect on blood pressure. A large meta-analysis of randomized controlled trials in the AHA journal Hypertension found that magnesium lowered systolic pressure by about 2.8 mmHg and diastolic pressure by about 2 mmHg compared to placebo.

The effects were much larger in certain groups. People who already had high blood pressure and were taking blood pressure medication saw an additional systolic drop of nearly 8 mmHg when they added magnesium. Those with low magnesium levels to begin with saw a systolic reduction of about 6 mmHg and a diastolic reduction of nearly 5 mmHg. This suggests magnesium helps most when your body is actually deficient in it, which is common since many people don’t get enough from food alone. Dark leafy greens, nuts, seeds, and whole grains are the richest dietary sources.

Exercise Regularly

Aerobic exercise, the kind that raises your heart rate for a sustained period, consistently lowers blood pressure by 5 to 8 mmHg in people with hypertension. Walking, cycling, swimming, and jogging all work. The general target is 150 minutes of moderate-intensity activity per week, which breaks down to about 30 minutes on most days.

Resistance training (lifting weights, using resistance bands) also contributes, though the effect on blood pressure is slightly smaller than aerobic exercise. The combination of both types is ideal. Consistency matters more than intensity. A daily 30-minute walk does more for your blood pressure over time than occasional intense workouts.

Limit Alcohol

Alcohol raises blood pressure, and the more you drink, the higher it goes. The American Heart Association recommends no more than two drinks per day for men and one for women. If you have high blood pressure, your doctor may recommend cutting back further or stopping entirely. Reducing heavy drinking to moderate levels can lower systolic blood pressure by 2 to 4 mmHg. If you don’t currently drink, there’s no blood pressure benefit to starting.

Practice Slow Breathing

Slow, controlled breathing exercises activate the body’s relaxation response and reduce the nervous system activity that keeps blood pressure elevated. A 12-week study found that regular slow breathing practice lowered systolic pressure by about 2.4 mmHg on average. Among participants who started with systolic readings above 120 or diastolic above 90, the reduction was much more dramatic: systolic dropped by 10.3 mmHg and diastolic by 3.8 mmHg.

The technique is simple. Breathe in slowly for about 5 seconds, then out slowly for about 5 seconds, aiming for roughly 6 breaths per minute. Doing this for 15 to 20 minutes daily is the typical approach studied in trials. It’s free, has no side effects, and pairs well with every other strategy on this list.

Address Sleep Problems

Poor sleep, particularly obstructive sleep apnea, has a direct connection to high blood pressure. Sleep apnea causes repeated drops in oxygen throughout the night, which triggers spikes in stress hormones that persist into the daytime and keep blood pressure elevated. This is especially relevant for people whose blood pressure doesn’t respond well to medication, a condition called resistant hypertension. In those patients, untreated sleep apnea is a common underlying cause.

Short sleep duration (consistently under 6 hours) is also linked to a higher risk of developing hypertension, though much of that connection appears to run through weight gain. If you snore loudly, wake up gasping, or feel exhausted despite a full night’s sleep, getting evaluated for sleep apnea could be one of the most impactful things you do for your blood pressure.

When Lifestyle Changes Aren’t Enough

If your blood pressure stays elevated after making meaningful lifestyle changes, or if it’s very high at diagnosis, medication is the next step. Four classes of blood pressure drugs are considered appropriate as first-line options: thiazide diuretics (which help your kidneys release sodium and water), ACE inhibitors, ARBs, and calcium channel blockers. Each works through a different mechanism, and the best choice depends on your other health conditions, your age, and how your body responds.

A large real-world study published in The American Journal of Medicine found that these four classes performed comparably for blood pressure reduction, though thiazides had a slight edge in reducing the risk of heart attack, stroke, and heart failure compared to beta-blockers, which are sometimes used as an alternative. Most people start on one medication, and the dose or combination is adjusted over the following weeks based on how their numbers respond.

Medication and lifestyle changes aren’t competing strategies. They work best together. The same habits that lower blood pressure on their own also make medication more effective, sometimes allowing for lower doses over time.
