If your blood pressure is high, the most effective things you can do are lose excess weight, change how you eat, exercise regularly, and work with your doctor on whether you need medication. Most people with high blood pressure need a combination of lifestyle changes, not just one fix. The good news: these changes can lower your numbers meaningfully, sometimes enough to avoid or reduce medication.
Know Your Numbers First
Blood pressure is measured in two numbers: systolic (the top number, when your heart pumps) and diastolic (the bottom number, between beats). The 2025 guidelines from the American Heart Association and American College of Cardiology define the categories like this:
- Normal: below 120/80
- Elevated: 120 to 129 systolic, with diastolic still below 80
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140/90 or higher
If your reading falls into two different categories (say, stage 1 systolic but normal diastolic), you go by the higher one. A single high reading doesn’t necessarily mean you have hypertension. Your doctor will want multiple readings over time to confirm the diagnosis.
How to Take Accurate Readings at Home
Home monitoring gives you and your doctor a much clearer picture than the occasional office visit. But technique matters a lot. Sit quietly for three to five minutes before you measure. Plant your feet flat on the floor, lean back against the chair, and rest your arm on a table so it’s level with your heart, palm facing up.
Place the cuff on your bare upper arm, about one inch above the bend of your elbow. The tubing should run down the front center of your arm so the sensor is properly positioned. Tighten it so you can just slip two fingertips under the top edge. After your first reading, wait one to two minutes before taking a second one. Recording both numbers gives you a more reliable average.
Change How You Eat
The DASH eating plan (Dietary Approaches to Stop Hypertension) is the most studied dietary pattern for blood pressure. It emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while cutting back on saturated fat and added sugars. The key target: keep sodium under 2,300 milligrams per day. Dropping to 1,500 mg daily lowers blood pressure even further.
For context, 2,300 mg is roughly one teaspoon of table salt. Most people consume well over that, largely from processed and restaurant foods, not from the salt shaker. Reading nutrition labels and cooking more at home are the two most practical ways to cut sodium without overthinking it.
Potassium works as a natural counterbalance to sodium. The more potassium you eat, the more sodium your body flushes through urine. Potassium also relaxes blood vessel walls, which directly lowers pressure. The American Heart Association recommends 3,500 to 5,000 mg of potassium daily for people managing high blood pressure, ideally from food rather than supplements. Bananas get all the credit, but potatoes, beans, spinach, yogurt, and avocados are all rich sources.
Lose Weight, Even a Little
If you’re carrying extra weight, even modest loss makes a real difference. A meta-analysis of 25 studies found that every kilogram of weight lost (about 2.2 pounds) drops blood pressure by roughly 1 mmHg. That means losing 10 pounds could reduce your systolic pressure by 4 to 5 points. It won’t solve everything on its own, but combined with dietary changes and exercise, the effects add up quickly.
Move More, Consistently
Regular aerobic exercise can lower systolic blood pressure by 4 to 10 points and diastolic by 5 to 8 points. That’s comparable to what some medications achieve. The target is at least 150 minutes per week of moderate-intensity activity (brisk walking, cycling, swimming) or 75 minutes of vigorous activity (running, high-intensity interval training).
Consistency matters more than intensity. Thirty minutes of brisk walking five days a week hits the 150-minute mark and is sustainable for most people. If you haven’t been active, start with 10- to 15-minute walks and build from there. The blood pressure benefits show up within a few weeks but disappear if you stop.
Cut Back on Alcohol
Alcohol raises blood pressure, and the effect is dose-dependent. For people managing hypertension, the recommended limit is up to one drink per day for women and up to two for men. One drink means 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of liquor. Drinking above these limits raises your blood pressure and can also interfere with the effectiveness of blood pressure medications.
Address Sleep Problems
Poor sleep, particularly obstructive sleep apnea, is one of the most overlooked drivers of high blood pressure. Sleep apnea causes your airway to repeatedly close during sleep, triggering stress responses that spike blood pressure. Among people with resistant hypertension (blood pressure that stays high despite taking three or more medications), roughly 82% have sleep apnea, and more than half have moderate to severe forms.
If you snore heavily, wake up gasping, or feel exhausted despite sleeping enough hours, sleep apnea is worth investigating. Treatment with a CPAP machine, which keeps the airway open overnight, has been shown to reduce blood pressure in people who use it consistently. The benefit is greatest in people with the highest blood pressure and best adherence to the therapy.
When Medication Is Needed
Lifestyle changes are the foundation, but many people also need medication, especially at stage 2 hypertension or when lifestyle changes alone don’t bring numbers down enough. Four classes of blood pressure drugs are considered appropriate first-line options: thiazide diuretics (which help your kidneys flush excess sodium and water), ACE inhibitors and ARBs (which relax blood vessels by targeting a hormone system that constricts them), and calcium channel blockers (which relax the muscles in blood vessel walls).
Which one your doctor starts with depends on your age, other health conditions, and how your body responds. Some people do well on a single medication. Others need two or three working in combination. It often takes some trial and adjustment to find the right fit. Blood pressure medication works only while you take it, so if your numbers look good, that’s a reason to keep going, not to stop.
Recognize a Hypertensive Crisis
A blood pressure reading of 180/120 or higher is a hypertensive crisis. If that number comes with symptoms like severe headache, chest pain, blurred vision, confusion, shortness of breath, nausea, or seizures, it’s an emergency that requires immediate medical attention. Organ damage can happen quickly at these levels.
If you get a reading that high but feel fine, wait five minutes and measure again. If it’s still at or above 180/120, contact your doctor or go to an urgent care facility. Don’t assume it will come down on its own.
Putting It All Together
No single change will fix high blood pressure for most people. The real power comes from stacking several changes together: eating more potassium-rich foods while cutting sodium, walking 30 minutes most days, losing even a small amount of weight, and sleeping well. Each of these might lower your systolic pressure by 4 to 10 points individually. Combined, they can rival or exceed the effect of medication. Track your home readings consistently, share them with your doctor, and treat this as a long-term project rather than a quick fix.
