If your blood pressure is high, the most important things you can do are adjust your diet, move more, and work with a provider to decide whether you need medication. What counts as “high” starts lower than many people expect: a reading of 130/80 or above now qualifies as stage 1 hypertension under current guidelines. The steps you take depend on how high your numbers are and whether you’re experiencing symptoms.
Know Your Numbers First
Blood pressure falls into clear categories based on the top number (systolic) and bottom number (diastolic):
- Elevated: 120–129 systolic with a diastolic below 80
- Stage 1 hypertension: 130–139 systolic or 80–89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
If your reading hits 180/120 or above, that’s a hypertensive crisis. Call 911 if you also have chest pain, shortness of breath, blurred vision, confusion, or stroke symptoms like numbness or tingling on one side of your body. If you get a reading that high at home but feel fine, sit quietly for a few minutes and recheck. If it stays very high, seek medical care.
Measure Accurately at Home
A single reading can be misleading. Home monitoring gives you and your provider a much clearer picture over time. To get reliable numbers, sit in a comfortable chair with your back supported for at least five minutes before taking a reading. Rest the arm wearing the cuff on a table at chest height. Place the cuff against bare skin, not over a sleeve, and make sure it’s snug without being tight.
Check at roughly the same times each day, ideally morning and evening. Write down both numbers along with the date and time so you can spot trends rather than reacting to any single spike.
Change What You Eat
Diet is one of the most powerful tools for lowering blood pressure without medication. The DASH eating plan, developed specifically for this purpose, emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while cutting back on saturated fat and added sugar. The key target is sodium: staying under 2,300 mg per day produces measurable results, and dropping to 1,500 mg lowers blood pressure even further.
Most excess sodium comes from processed and restaurant food, not the salt shaker. Reading labels, cooking more meals at home, and choosing fresh or frozen vegetables over canned ones can cut your intake significantly without dramatic changes to what you enjoy eating.
Boost Your Potassium
Potassium works as a counterbalance to sodium. It helps your blood vessels relax and encourages your kidneys to flush out extra salt. The recommended daily intake is 3,400 mg for men and 2,600 mg for women, but most people fall short. In studies of people with hypertension, increasing potassium intake lowered systolic pressure by about 4.5 points and diastolic by about 3 points.
Some of the richest food sources per serving include dried apricots (755 mg per half cup), cooked lentils (731 mg per cup), baked potato (610 mg), kidney beans (607 mg per cup), and raisins (618 mg per half cup). Getting potassium from food is generally preferred over supplements, especially if you have kidney problems or take medications that affect potassium levels.
Move More, Consistently
Regular exercise lowers blood pressure by making your heart more efficient and keeping your blood vessels flexible. The target is at least 150 minutes of moderate aerobic activity per week, or 75 minutes of vigorous activity. Walking briskly, cycling, and swimming all count. Combining aerobic exercise with weight training provides the most benefit for heart health.
You don’t need long sessions to see results. Three 10-minute walks throughout the day offer the same benefit as one 30-minute session. The key is consistency. Exercising most days of the week matters more than occasional intense workouts.
Lose Weight If You Need To
Carrying extra weight forces your heart to pump harder with every beat. The relationship between weight loss and blood pressure is remarkably direct: for every kilogram (about 2.2 pounds) you lose, systolic blood pressure drops by roughly 1 point. That means losing 10 pounds could lower your top number by 4 to 5 points. For someone in stage 1 hypertension, that reduction alone might be enough to bring readings back into a healthier range.
You don’t need to hit an ideal body weight to benefit. Even modest weight loss, combined with the dietary and exercise changes above, can produce meaningful drops in blood pressure within weeks.
Cut Back on Alcohol
Alcohol raises blood pressure, and the effect is dose-dependent. If you have high blood pressure, the safest approach is to drink very little or not at all. For those who do drink, the general 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 distilled spirits. Regularly exceeding those amounts can both raise your baseline blood pressure and reduce the effectiveness of blood pressure medications.
Address Sleep Problems
Poor sleep does more than leave you tired. It activates your body’s stress response system, raising levels of hormones that constrict blood vessels and increase heart rate. These effects persist into daytime hours, keeping blood pressure elevated around the clock. Short sleep duration and fragmented sleep are both linked to stiffer arteries, impaired blood vessel function, and blood pressure that doesn’t dip normally at night.
Obstructive sleep apnea deserves special attention. When your airway repeatedly closes during sleep, oxygen levels drop and your nervous system floods your body with stress hormones. Over time, this drives up inflammation throughout the cardiovascular system and can lead to resistant hypertension that doesn’t respond well to medication alone. Treating sleep apnea with a CPAP machine or an oral appliance lowers both systolic and diastolic pressure by 2 to 4 points on average, with larger benefits in people who have more severe apnea. If you snore heavily, wake up gasping, or feel exhausted despite what should be enough sleep, getting evaluated for sleep apnea is a practical step toward better blood pressure control.
When Lifestyle Changes Aren’t Enough
For many people, especially those with stage 2 hypertension or additional risk factors like diabetes or existing heart disease, medication is part of the plan from the start. The four main classes of blood pressure drugs each work differently. Diuretics widen blood vessels and help your kidneys flush extra fluid and salt. ACE inhibitors and ARBs both target a hormone called angiotensin II that constricts blood vessels, blocking either its production or its effect. Calcium channel blockers relax the muscles in blood vessel walls by preventing calcium from entering the cells.
Your provider chooses a medication based on your overall health, other conditions you have, and how you respond. Some people do well on a single drug at a low dose. Others need a combination. It often takes some adjustment to find the right fit, and side effects like fatigue, dizziness, or frequent urination are worth reporting so your provider can make changes. Medication works best alongside the lifestyle changes above, not as a replacement for them.
