Managing high blood pressure comes down to a combination of daily habits and, when needed, medication. Most people can lower their numbers meaningfully through changes to diet, exercise, weight, and alcohol intake. For some, those lifestyle shifts are enough on their own. For others, they work alongside medication to bring blood pressure into a safer range. The key is knowing your numbers, understanding what moves them, and building a plan you can actually stick with.
Know Your Numbers
Blood pressure falls into four categories. Normal is below 120/80 mmHg. Elevated is 120 to 129 systolic with diastolic still under 80. Stage 1 hypertension is 130 to 139 systolic or 80 to 89 diastolic. Stage 2 hypertension is 140/90 or higher. If your systolic and diastolic readings land in different categories, the higher one is the one that counts.
A single high reading doesn’t necessarily mean you have hypertension. Your doctor will want to see a pattern across multiple visits. Home monitoring helps fill in the picture between appointments and gives a more accurate sense of your day-to-day blood pressure than occasional office readings.
How to Measure Accurately at Home
Home monitors are widely available and straightforward to use, but technique matters. Sit in a comfortable chair with your back supported for at least five minutes before taking a reading. Rest your arm on a table at chest height with the cuff snug against bare skin, not over clothing. Take at least two readings one to two minutes apart and record both. Measure at the same time each day for consistency, ideally in the morning and evening.
Bring your log to every doctor’s appointment. Patterns over weeks are far more useful than any single number, and your provider can use this data to decide whether to adjust treatment or stay the course.
Reshape Your Diet
The DASH eating plan (Dietary Approaches to Stop Hypertension) is the most well-studied dietary pattern for lowering blood pressure. It emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while cutting back on saturated fat and added sugars. It’s not a fad diet. It’s a long-term framework that reliably lowers blood pressure even without medication changes.
Sodium is a major lever. The standard recommendation is to stay under 2,300 milligrams per day, roughly one teaspoon of table salt. Cutting further to 1,500 milligrams produces even larger drops in blood pressure. Most excess sodium doesn’t come from the salt shaker. It hides in bread, deli meat, canned soups, frozen meals, and restaurant food. Reading labels and cooking more meals at home are the most effective ways to reduce intake.
Potassium works in the opposite direction of sodium, helping your body flush out excess salt and easing tension in blood vessel walls. Most adults need about 2,600 to 3,400 milligrams per day, depending on sex. Bananas get all the credit, but potatoes, spinach, beans, yogurt, and avocados are equally good sources. One important caveat: people with kidney disease, or those taking certain blood pressure medications that affect potassium levels, can develop dangerously high potassium. If either applies to you, talk with your provider before increasing your intake or using salt substitutes, which are often potassium-based.
Move More, Consistently
Regular aerobic exercise lowers blood pressure by 5 to 8 points diastolic and 4 to 10 points systolic. That’s comparable to what some medications deliver. The target is 150 minutes per week of moderate-intensity activity, things like brisk walking, cycling, or swimming, or 75 minutes of vigorous activity like running or high-intensity interval training.
You don’t need to do it all at once. Splitting it into daily 20- to 30-minute sessions works just as well. The effect is dose-dependent, meaning more activity generally produces better results, but even modest increases from a sedentary baseline make a real difference. Consistency matters more than intensity. A daily walk you actually take beats a gym membership you never use.
Lose Weight If You Need To
Excess body weight is one of the strongest predictors of high blood pressure, and losing it is one of the most effective non-drug interventions. A meta-analysis of 25 studies found that every kilogram of weight lost (about 2.2 pounds) is associated with roughly a 1 mmHg drop in blood pressure. That means losing 10 kilograms, or about 22 pounds, could lower your systolic pressure by around 10 points.
You don’t need to reach an ideal weight to see benefits. Even a 5 to 10 percent reduction in body weight can meaningfully improve your numbers. The combination of dietary changes and regular exercise tends to be more sustainable and more effective than either approach alone.
Limit Alcohol
Drinking too much raises blood pressure and can blunt the effectiveness of medication. The general guideline is no more than one drink per day for women and two for men. One drink means 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of spirits. Exceeding these limits regularly can push blood pressure higher over time, and heavy drinking episodes cause temporary spikes that stress the cardiovascular system.
Other Habits That Help
Stress doesn’t directly cause chronic hypertension, but it triggers temporary spikes and can drive behaviors (overeating, drinking, skipping exercise) that do. Techniques like deep breathing, meditation, and regular physical activity help blunt the stress response over time.
Sleep is underappreciated. Obstructive sleep apnea, a condition where breathing repeatedly stops during sleep, is present in roughly 82 percent of people with resistant hypertension, the kind that doesn’t respond well to standard treatment. If you snore heavily, wake up gasping, or feel exhausted despite a full night’s sleep, getting evaluated for sleep apnea could be the missing piece. Treating it with a CPAP machine can improve blood pressure, particularly in people with higher readings who use the device consistently.
Smoking doesn’t appear in the blood pressure categories the way sodium does, but it damages blood vessels and accelerates the cardiovascular harm that high blood pressure already causes. Quitting won’t directly lower your reading, but it dramatically reduces your overall risk of heart attack and stroke.
When Medication Is Needed
Lifestyle changes are the foundation, but many people also need medication, especially at stage 2 or when cardiovascular risk is already elevated. There are four first-line classes your provider will typically choose from, each working through a different mechanism:
- Thiazide diuretics widen blood vessels and help your kidneys flush extra fluid and salt.
- ACE inhibitors block your body from producing a chemical that constricts blood vessels.
- ARBs prevent that same chemical from tightening vessels, through a slightly different pathway than ACE inhibitors.
- Calcium channel blockers relax the muscle in blood vessel walls by limiting calcium from entering those cells.
Your provider may start with one medication and adjust based on how you respond. Some people end up on two or three drugs from different classes. This isn’t a sign that something is wrong. It just means the condition needs more than one approach, the same way diet plus exercise works better than either alone. Side effects vary by class, so if one medication causes problems like a persistent cough, dizziness, or swelling, alternatives usually exist.
Blood Pressure Targets
For most adults, the treatment goal is below 130/80 mmHg. A major NIH-funded trial called SPRINT found that pushing systolic pressure below 120 in adults age 50 and older significantly reduced cardiovascular events and death. That more aggressive target isn’t right for everyone, though. For older adults, especially those managing multiple health conditions, the ideal target depends on overall fitness, fall risk, and medication tolerance. Your provider will balance the benefit of lower numbers against the practical risks of pushing too hard.
Managing blood pressure is a long game. The habits that lower it take weeks to show full effect, and medications sometimes need adjustment over months. Tracking your readings at home, staying consistent with lifestyle changes, and keeping regular follow-ups gives you the clearest path to keeping your numbers where they need to be.
