If your blood pressure is high, the most important thing to do right now depends on how high it is. A reading of 180/120 or above with symptoms like chest pain, blurred vision, or shortness of breath is a medical emergency. Anything below that threshold calls for a combination of lifestyle changes and, in many cases, medication to bring your numbers down and keep them there.
Know Your Numbers First
Blood pressure falls into four categories based on the 2025 guidelines from the American Heart Association and American College of Cardiology:
- Normal: below 120/80
- Elevated: 120 to 129 systolic (top number) and below 80 diastolic (bottom number)
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
Where you fall on this scale shapes what comes next. Elevated blood pressure and Stage 1 hypertension can often be managed with lifestyle changes alone, at least initially. Stage 2 typically calls for medication alongside those same changes. A single high reading doesn’t necessarily mean you have hypertension, though. Your doctor will want to see a pattern across multiple readings before making a diagnosis.
When High Blood Pressure Is an Emergency
A reading of 180/120 or higher is called a hypertensive crisis. If you see that number on your monitor and you’re experiencing chest pain, shortness of breath, confusion, blurred vision, or stroke symptoms like sudden numbness or tingling on one side of your body, call 911 immediately. Don’t wait to see if the number comes down on its own.
If your reading hits 180/120 but you feel fine, wait five minutes, sit quietly, and measure again. If it’s still that high, contact your doctor’s office for guidance the same day.
Change What You Eat
Diet is one of the most powerful tools you have. The DASH eating pattern (Dietary Approaches to Stop Hypertension) emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while limiting saturated fat and sweets. In clinical trials, people following the DASH diet lowered their systolic blood pressure by about 11 points on average compared to a standard diet. That’s a meaningful drop, roughly equivalent to what some medications achieve.
The core of this approach is straightforward: more produce, more whole grains, less processed food. You don’t need to follow a rigid meal plan. Even partial shifts toward this pattern help.
Cut Back on Sodium
The American Heart Association recommends no more than 2,300 milligrams of sodium per day, with an ideal limit of 1,500 milligrams for most adults with high blood pressure. For context, a single teaspoon of table salt contains about 2,300 milligrams, and most sodium in the American diet comes from restaurant meals, packaged foods, and deli meats rather than the salt shaker at home. Reading nutrition labels and cooking more meals yourself are the two simplest ways to cut sodium significantly.
Get More Potassium
Potassium helps counterbalance sodium’s effect on blood pressure. The World Health Organization recommends at least 3,510 milligrams per day for adults. Good sources include bananas, potatoes, spinach, beans, yogurt, and avocados. If you have kidney disease, though, your potassium needs are different, so talk with your doctor before deliberately increasing your intake.
Move Your Body Regularly
Aim for at least 150 minutes of moderate aerobic activity per week, or 75 minutes of vigorous activity. That works out to about 30 minutes on most days. Walking, swimming, cycling, and dancing all count. If 30 minutes at once feels like too much, three 10-minute sessions throughout the day deliver the same benefit.
A combination of aerobic exercise and weight training provides the strongest benefit for heart health. You don’t need a gym membership. Bodyweight exercises like squats, push-ups, and resistance bands at home work well. The key is consistency over intensity, especially when you’re starting out.
Lose Weight If You Need To
Carrying extra weight makes your heart work harder to pump blood, which raises pressure in your arteries. A meta-analysis published in the AHA’s journal Hypertension found that for every kilogram (about 2.2 pounds) of weight lost, systolic blood pressure drops roughly 1 point and diastolic drops about 0.9 points. That means losing 10 kilograms (22 pounds) could lower your systolic reading by around 10 points, a substantial improvement.
You don’t need to reach an ideal body weight to see results. Even modest weight loss of 5 to 10 percent of your current weight can make a real difference in your blood pressure readings.
Limit Alcohol
Alcohol raises blood pressure, and the effect compounds with heavier drinking. If you have high blood pressure, the safest approach is to avoid alcohol entirely or keep it to a minimum: 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 80-proof spirits. Regularly exceeding those limits can both raise your blood pressure and reduce the effectiveness of blood pressure medication.
Medication: What to Expect
When lifestyle changes aren’t enough, or when blood pressure is already at Stage 2, your doctor will likely prescribe medication. The four main classes of blood pressure drugs each work differently. Some help your body get rid of excess fluid, others relax blood vessel walls, and others reduce the effect of hormones that tighten your arteries. Your doctor chooses based on your overall health, other conditions you have, and how your body responds.
Most people start on one medication. If that doesn’t bring your numbers to target, a second drug from a different class is often added because two medications working on different systems tend to be more effective together than doubling down on one approach. Finding the right combination can take a few weeks or months of adjustments. Blood pressure medication is typically a long-term commitment, not a short course you take until things improve.
Monitor Your Blood Pressure at Home
Home monitoring helps you track whether what you’re doing is working and gives your doctor better data than occasional office visits alone. To get accurate readings, follow a consistent routine:
- Avoid caffeine, smoking, and exercise for 30 minutes before measuring.
- Empty your bladder before sitting down.
- Sit quietly for five minutes before taking a reading. No talking, no phone.
- Position your arm correctly: rest it on a flat surface at heart level, with the cuff on bare skin just above the bend of your elbow.
- Measure at the same time each day, ideally morning and evening.
Write down your readings or use an app to log them. A single high reading isn’t cause for panic, but a pattern of consistently elevated numbers tells you and your doctor that something needs to change. Bring your log to every appointment so your doctor can see the full picture rather than relying on a single in-office measurement, which can be artificially high due to the stress of being in a medical setting.
