Several lifestyle changes can lower blood pressure by meaningful amounts, and combining them often works as well as medication for people with mildly elevated readings. The most effective strategies target diet, exercise, weight, sodium intake, alcohol, and stress. Here’s what the evidence shows for each, including the actual numbers.
Know Your Numbers First
The 2025 guidelines from the American Heart Association define four blood pressure 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 fall into different categories, the higher one applies.
These categories matter because a drop of even 5 mmHg in systolic pressure significantly reduces the risk of heart attack and stroke at a population level. Many of the strategies below deliver that kind of reduction on their own, and they stack when you combine them.
Change What You Eat
The most studied dietary pattern for blood pressure is the DASH diet, which emphasizes fruits, vegetables, whole grains, lean protein, and low-fat dairy while limiting saturated fat and sweets. In a large meta-analysis of randomized controlled trials, people following the DASH diet lowered their systolic pressure by an average of 3.2 mmHg and diastolic by 2.5 mmHg compared to a control diet. Those reductions were larger in people who already had hypertension.
The DASH diet works partly because it’s naturally high in potassium, magnesium, calcium, and fiber. The World Health Organization recommends adults get at least 3,510 mg of potassium per day, which most people fall short of. Good sources include bananas, potatoes, spinach, beans, and yogurt. If you have kidney disease, talk to your doctor before increasing potassium, since impaired kidneys can’t clear it efficiently.
Cut Back on Sodium
Reducing sodium has one of the most reliable effects on blood pressure. According to a WHO analysis, cutting salt intake by about 6 grams per day (roughly one teaspoon) lowered systolic pressure by 5.8 mmHg on average. The effect was nearly twice as large in people with hypertension: 10.8 mmHg. Even in people with normal blood pressure, the same reduction dropped systolic readings by 4.3 mmHg.
Most dietary sodium doesn’t come from the salt shaker. It’s hidden in bread, deli meats, canned soups, sauces, and restaurant food. Reading labels and cooking at home more often are the two most practical ways to bring your intake down. The current recommendation is no more than 2,300 mg of sodium per day, and closer to 1,500 mg if you already have high blood pressure.
Move More
Regular aerobic exercise, things like brisk walking, cycling, or swimming, lowers systolic blood pressure by 3 to 5 mmHg in people with normal readings and by about 7 mmHg systolic and 5 mmHg diastolic in people with hypertension. That’s comparable to what some blood pressure medications achieve.
Even people with resistant hypertension (blood pressure that stays high despite medication) benefit. In one study published in the AHA journal Hypertension, a structured aerobic exercise program lowered daytime systolic pressure by about 6 mmHg in this hard-to-treat group. Most guidelines recommend at least 150 minutes of moderate-intensity aerobic exercise per week, spread across most days rather than crammed into one or two sessions.
Lose Weight If You Carry Extra
Weight loss has a dose-dependent effect on blood pressure. A meta-analysis of randomized trials found that every kilogram (about 2.2 pounds) of weight lost reduces systolic pressure by roughly 1 mmHg and diastolic by about 0.9 mmHg. That means losing 10 pounds could drop your systolic reading by 4 to 5 points. The effect is consistent whether the weight comes off through diet, exercise, or both.
You don’t need to reach an ideal body weight to see results. Even modest weight loss of 5 to 10 percent of body weight produces clinically meaningful blood pressure improvements, especially if you’re starting with elevated readings.
Drink Less Alcohol
There’s no safe threshold for alcohol when it comes to blood pressure. A large dose-response meta-analysis found that the relationship between alcohol and systolic pressure is linear: the more you drink, the higher it goes, with no level of consumption that’s neutral. As little as one standard drink per day (12 grams of alcohol) was associated with systolic pressure 1.25 mmHg higher than nondrinkers. At four drinks per day, the gap widened to nearly 5 mmHg systolic and 3 mmHg diastolic.
If you currently drink regularly, reducing your intake is one of the simpler ways to bring your numbers down. The benefit starts quickly, often within weeks of cutting back.
Manage Stress
Chronic stress keeps your body in a state that constricts blood vessels and raises heart rate, both of which push blood pressure up. Mindfulness-based stress reduction programs lasting eight weeks have been shown to lower systolic pressure by about 7 mmHg and diastolic by roughly 2.5 mmHg. Breathing-focused meditation practiced over 12 weeks reduced systolic pressure by about 4 mmHg.
You don’t need a formal program. Slow, deep breathing for 10 to 15 minutes a day, regular physical activity (which also reduces stress hormones), and consistent sleep all help regulate the body’s stress response. The key is consistency over weeks and months rather than occasional sessions.
Check for Sleep Apnea
Obstructive sleep apnea, where your airway repeatedly collapses during sleep, is one of the most common and overlooked contributors to high blood pressure. It’s especially worth investigating if your blood pressure stays elevated despite lifestyle changes or medication, if you snore heavily, or if you wake up feeling unrested.
Treatment with a CPAP machine (which keeps your airway open at night) lowers blood pressure by about 2 mmHg on average across studies, though certain people see much larger drops. The modest average likely reflects the fact that many patients struggle to use CPAP consistently. Those who wear it regularly throughout the night tend to get the biggest benefit.
Try Hibiscus Tea
Among natural supplements, hibiscus tea has some of the strongest clinical evidence. In a controlled trial with people who had prehypertension or mild hypertension, drinking three cups of brewed hibiscus tea daily for six weeks lowered systolic blood pressure by 7.2 mmHg compared to a 1.3 mmHg drop with placebo. The diastolic reduction was smaller and didn’t reach statistical significance. It’s a low-risk option that can complement other changes, though it won’t replace the bigger-ticket items like exercise and dietary overhaul.
Stacking Strategies Adds Up
None of these interventions works in isolation as well as they work together. Someone who adopts a DASH-style diet (3 mmHg), reduces sodium meaningfully (5 to 6 mmHg), exercises regularly (5 to 7 mmHg), loses some weight (4 to 5 mmHg), and cuts back on alcohol could see a combined systolic reduction of 15 to 20 mmHg or more. That’s enough to move many people from Stage 1 hypertension back into the normal range without medication.
The reductions aren’t always perfectly additive, since these habits influence some of the same biological pathways. But they’re close enough that the combination is consistently more powerful than any single change. Start with whichever feels most achievable, build the habit, and layer in additional changes over time.
