Pulse pressure is the difference between your systolic (top) and diastolic (bottom) blood pressure numbers. A normal pulse pressure sits around 40 mmHg. Readings above 60 mmHg are a risk factor for heart disease, particularly in older adults. Lowering pulse pressure involves a combination of dietary changes, exercise, weight management, and sometimes medication, all aimed at keeping your arteries flexible and reducing strain on your heart.
What Pulse Pressure Tells You
If your blood pressure is 130/80, your pulse pressure is 50 mmHg. That’s slightly above the healthy benchmark of 40 but below the danger zone of 60. The number matters because it reflects how stiff or flexible your arteries are. As you age, the elastic fibers in artery walls break down and calcium deposits build up. This makes arteries rigid, which forces your systolic pressure higher while your diastolic pressure stays the same or even drops. The growing gap between those two numbers is your pulse pressure widening.
A wide pulse pressure isn’t just a marker of stiff arteries. It actively increases the pounding force that blood exerts on your organs with every heartbeat. Data from the Framingham Heart Study shows that elevated pulse pressure combined with arterial stiffness is linked to higher rates of heart attack, stroke, heart failure, and thickening of the heart muscle. Bringing that number down reduces the mechanical stress on your cardiovascular system.
Cut Sodium to See Fast Results
Reducing salt intake is one of the most direct ways to lower pulse pressure, especially if your systolic number is already high. A combined analysis of four studies found that cutting daily salt from about 10 grams to 5 or 6 grams for one month lowered pulse pressure by 9 mmHg in people with isolated systolic hypertension (high top number, normal bottom number). That’s a meaningful reduction from a single dietary change. People with both numbers elevated saw a smaller but still significant 3 mmHg drop.
Salt reduction works disproportionately well on pulse pressure because it lowers systolic pressure more than diastolic. Most people consume far more sodium than they realize, since roughly 70% comes from processed and restaurant foods rather than the salt shaker. Reading labels and cooking more meals at home are the most practical starting points.
Eat More Potassium-Rich Foods
Potassium works alongside sodium reduction by helping blood vessels relax. It stimulates the production of nitric oxide in the cells lining your arteries, which widens them and improves flexibility. It also appears to slow the calcification process that stiffens arteries over time.
A study of over 2,000 adults found that for every additional 1,000 mg of daily potassium, pulse pressure dropped by about 1.5 mmHg. Those eating the most potassium (averaging around 3,800 mg per day) had pulse pressures nearly 3 mmHg lower than those eating the least. The recommended adequate intake is 2,600 mg per day for women and 3,400 mg for men. Good sources include bananas, potatoes, spinach, beans, avocados, and yogurt.
Aerobic Exercise Loosens Stiff Arteries
Regular aerobic exercise directly reduces arterial stiffness, the root cause of elevated pulse pressure in most people. Walking, jogging, cycling, and swimming all qualify. The key finding from exercise research is that you don’t need to work out intensely or for long sessions to see benefits. One study found that arterial stiffness decreased after just 15 minutes of aerobic exercise per day, three times a week, over eight weeks. There was no significant difference between low and moderate intensity, meaning a brisk walk is roughly as effective as a jog for this purpose.
Most studies showing reduced arterial stiffness use sessions lasting 20 to 60 minutes. If you’re starting from a sedentary baseline, even 15-minute walks three days a week is a reasonable beginning. The consistency matters more than the intensity.
Lose Weight to Improve Artery Flexibility
Carrying excess weight accelerates arterial stiffening. In overweight and obese young adults, lifestyle interventions that produced weight loss led to measurable improvements in arterial stiffness. Reductions in weight, BMI, and waist circumference were all independently associated with more flexible arteries during the study period. This means that losing weight through any combination of diet and exercise can help, and you don’t necessarily need to reach a “normal” BMI to start seeing vascular benefits. Even modest losses improve the elasticity of your blood vessels.
Omega-3 Fatty Acids and Blood Pressure
Omega-3 fatty acids from fish oil have a modest but real effect on blood pressure. A large meta-analysis of randomized trials found the optimal dose for lowering blood pressure was between 2 and 3 grams per day, which reduced systolic pressure by about 2.6 mmHg and diastolic by about 1.7 mmHg. Because omega-3s tend to lower systolic pressure slightly more than diastolic, they can nudge pulse pressure in the right direction. Higher doses (above 3 grams per day) may provide additional benefit for people at high cardiovascular risk. You can get omega-3s from fatty fish like salmon, mackerel, and sardines, or from supplements.
How Medications Target Pulse Pressure
The 2025 AHA/ACC blood pressure guidelines set an overall treatment goal of below 130/80 mmHg for all adults. When lifestyle changes aren’t enough, medication enters the picture. Not all blood pressure drugs are equally effective at lowering pulse pressure specifically. A comparison study found that ACE inhibitors, calcium channel blockers, and thiazide diuretics all reduced central pulse pressure significantly. Beta-blockers, by contrast, had no meaningful effect on central pulse pressure despite lowering peripheral blood pressure readings. This distinction matters if your primary concern is a wide pulse pressure rather than elevated blood pressure across the board.
Your doctor’s choice of medication will depend on your full cardiovascular picture, but if pulse pressure is a specific concern, it’s worth discussing which drug class is most appropriate for you.
When a Wide Pulse Pressure Has a Structural Cause
In some cases, a wide pulse pressure isn’t driven by arterial stiffness at all. Aortic regurgitation, a condition where the aortic valve doesn’t close completely and allows blood to leak backward into the heart, causes systolic pressure to climb and diastolic pressure to fall. This creates a characteristically wide pulse pressure that won’t respond to the usual lifestyle measures. Treatment for this condition typically involves surgical valve replacement or repair when the leak becomes severe enough to stress the heart. Certain blood pressure medications called angiotensin receptor blockers may be used if hypertension is also present, though they don’t fix the valve itself. Beta-blockers are used cautiously in this situation because slowing the heart rate can actually worsen the leak.
If your pulse pressure is notably wide and you haven’t been evaluated for valve problems, an echocardiogram can rule this out. This is especially relevant if you also notice symptoms like shortness of breath, a bounding pulse you can feel in your neck, or exercise intolerance.
Putting It Together
The strategies with the strongest evidence for lowering pulse pressure, ranked roughly by the size of their effect: cutting sodium intake in half (up to 9 mmHg reduction), regular aerobic exercise (measurable improvement in arterial stiffness within 8 weeks), increasing potassium intake (about 1.5 mmHg per additional 1,000 mg daily), losing excess weight, and supplementing with 2 to 3 grams of omega-3 fatty acids. These approaches work through overlapping mechanisms, so combining them produces larger benefits than any single change. If your pulse pressure remains above 60 mmHg despite consistent lifestyle modifications, medication that specifically targets central pulse pressure can close the remaining gap.
