High blood pressure(hypertension) is called the “silent killer” for good reason. It often has no symptoms but is a major risk of heart disease and stroke. And these diseases are among the leading causes of death in the United States (
Almost half of U.S. adults have high blood pressure (
Your blood pressure is measured in millimeters of mercury, which is abbreviated as mm Hg. There are twonumbersinvolved in the measurement:
- Systolic blood pressure.The top number represents the force of the pressure when your heart pushes blood into the arteries throughout the rest of your body.
- Diastolic blood pressure.The bottom number represents the pressure in your blood vessels between beats, when your heart is filling and relaxing.
Your blood pressure depends on how much blood your heart is pumping, and how much resistance there is to blood flow in your arteries. The narrower your arteries, the higher your blood pressure.
Blood pressure lower than 120/80 mm Hg is considered normal. Blood pressure that’s 130/80 mm Hg or more isconsidered high.
If your numbers are above normal but under 130/80 mm Hg, you fall into the category of elevated blood pressure. This means you’re at risk of developing high blood pressure (3).
The good news aboutelevated blood pressureis that you can make changes to significantly reduce your numbers and lower your risk — without requiring medications.
Here are 17 effective ways to lower your blood pressure levels.
A meta-analysis of 65 studies suggests that aerobic and resistance exercise can significantly lower blood pressure, especially for men (
In a 2013 study, sedentary older adults who participated in aerobic exercise training lowered their blood pressure by an average of 3.9 percent systolic and 4.5 percent diastolic (5). These results are as good as someblood pressure medications.
As you regularly increase your heart and breathing rates, over time your heart gets stronger and pumps with less effort. This puts less pressure on your arteries and lowers your blood pressure.
How much activity should you strive for?
A 2019 report by the American College of Cardiology and the American Heart Association advises moderate- to vigorous-intensity physical activity for 40-minute sessions, three to four times per week (
If finding 40 minutes at a time is a challenge, there may still be benefits when the time is divided into three or four 10- to 15-minute segments throughout the day (
The American College of Sports Medicine makes similar recommendations (8).
But you don’t have to run marathons. Increasing your activity level can be as simple as:
- using the stairs
- walking instead of driving
- doing household chores
- gardening
- going for abike ride
- playing a team sport
Just do it regularly and work up to at least half an hour per day of moderate activity.
One example of moderate activity that can have big results is tai chi. A 2017 review on the effects of tai chi and high blood pressure shows an overall average of a 15.6 mm Hg drop in systolic blood pressure and a 10.7 mm Hg drop in diastolic blood pressure compared with no exercise at all (
2014年回顾运动和降低血液出版社ure found that there are many combinations of exercise that can lower blood pressure (
These exercises include:
- aerobic exercise
- resistance training
- high-intensity interval training
- short bouts of exercise throughout the day
- walking 10,000 steps a day
Ongoing studies continue to suggest that there are still benefits to even light physical activity, especially for older adults (11).
If you’re overweight, losing 5 to 10 pounds can reduce your blood pressure. Plus, you’ll lower your risk of other potential medical problems.
A review of several studies reports thatweight loss dietsreduced blood pressure by an average of 3.2 mm Hg diastolic and 4.5 mm Hg systolic (12).
Many studies show thatrestricting sugarandrefined carbohydratescan help you lose weightandlower your blood pressure.
Sugar, especially fructose, may increase your blood pressure more than salt, according to one 2014 review. In trials lasting at least 8 weeks, sugar increased blood pressure by 5.6 mm Hg diastolic and 6.9 mm Hg systolic (13).
A 2020 study that compared various popular diets found that for people who with more weight or obesity,low carbandlow fatdiets lowered their diastolic blood pressure by an average of about 5 mm Hg and their systolic blood pressure 3 mm Hg after 6 months (
Another benefit of a low carb, low sugar diet is that you feel fuller longer, because you’re consuming moreproteinand fat.
Best foods for high blood pressure
Increasing yourpotassiumintake and cutting back on salt can also lower your blood pressure (15).
Potassium is a double winner: It lessens the effects of salt in your system and eases tension in your blood vessels. However, diets rich in potassium may be harmful to people withkidney disease, so talk with your doctor before increasing your potassium intake.
It’s easy to eat more potassium. So manyfoodsare naturally high in potassium. Here are a few:
- low fat dairy foods, such asmilkandyogurt
- fish
- fruits, such asbananas,apricots,avocados, andoranges
- vegetables, such assweet potatoes,potatoes,tomatoes, greens, andspinach
Note that people respond tosaltdifferently. Some people are salt-sensitive, meaning that a higher salt intake increases their blood pressure. Others are salt-insensitive. They can have a high salt intake and excrete it in their urine without raising their blood pressure (16).
The National Institutes of Health recommends reducing salt intake using the DASH (Dietary Approaches to Stop Hypertension) diet (
- low sodium foods
- fruitsandvegetables
- low fat dairy
- whole grains
- fish
- poultry
- beans
- fewer sweets and red meats
Most of the extra salt in your diet comes fromprocessed foodsand foods from restaurants, not your salt shaker at home (
- deli meats
- canned soup
- pizza
- 芯片
- other processed snacks
Foods labeled “low fat” are usually high in salt and sugar to compensate for the loss of fat. Fat is what gives food taste and makes you feel full.
Cutting down on — or even better, cutting out — processed food will help you eat less salt, less sugar, and fewer refined carbohydrates. All of this can result in lower blood pressure.
Make it a practice to checknutrition labels. According to the Food and Drug Administration (FDA), a sodium listing of 5 percent or less on a food label is considered low, while 20 percent or more is considered high (
It can be difficult to do, but it’s worth it:Stopping smokingis good for your all-around health.Smokingcauses an immediate but temporary increase in your blood pressure and an increase in your heart rate (20).
In the long term, the chemicals in tobacco can increase your blood pressure by damaging your blood vessel walls, causing inflammation, and narrowing your arteries. The hardened arteries cause higher blood pressure.
The chemicals in tobacco can affect your blood vessels even if you’re aroundsecondhand smoke.
A study showed that nonsmokers who were able to go to smoke-free restaurants, bars, and workplaces had lower blood pressure than nonsmokers in areas that had no smoke-free policies affecting public places (
We live in stressful times. Workplace and family demands, national and international politics — they all contribute to stress. Finding ways toreduce your own stressis important for your health and your blood pressure.
There are lots of ways to successfully relievestress, so find what works for you. Practicedeep breathing, take a walk, read a book, or watch a comedy.
Listening to music daily has also been shown to reduce systolic blood pressure (22).
A 20-year study showed that regularsaunause reduced death from heart-related events (23).
And one small 2015 study has shown thatacupuncturecan lower both systolic and diastolic blood pressure (24).
Mindfulnessandmeditation, including transcendental meditation, have long been used — and studied — as methods to reduce stress.
Yoga, which commonly involves breathing control, posture, and meditation techniques, can also be effective in reducing stress and blood pressure.
2013年回顾发现瑜伽和血压average blood pressure decrease of 3.62 mm Hg diastolic and 4.17 mm Hg systolic when compared with those who didn’t exercise.
Studies of yoga practices that included breath control, postures, and meditation were nearly twice as effective as yoga practices that didn’t include all three of these elements (25).
Yes, chocolate lovers:Dark chocolatehas been shown to lower blood pressure.
But the dark chocolate should be 60 to 70 percent cacao. A review of studies on dark chocolate has found that eating one to two squares of dark chocolate per day may help lower the risk of heart disease by lowering blood pressure and inflammation.
The benefits are thought to come from the flavonoids present in chocolate with more cocoa solids. The flavonoids help dilate, or widen, your blood vessels (26).
Herbal medicineshave long been used in many cultures to treat a variety of ailments.
Some herbs have even been shown to possibly lower blood pressure. However, more research is needed to identify the doses and components in the herbs that are most useful.
Always check with your doctor or pharmacist before taking herbal supplements. They may interfere with your prescription medications.
Here’s a partial list of plants and herbs that are used by cultures throughout the world to lower blood pressure:
- black bean (Castanospermum australe)
- cat’s claw(Uncaria rhynchophylla)
- celery juice(Apium graveolens)
- Chinese hawthorn (Crataegus pinnatifida)
- ginger root
- giant dodder (Cuscuta reflexa)
- Indian plantago (blond psyllium)
- maritime pine bark (Pinus pinaster)
- river lily (Crinum glaucum)
- roselle (Hibiscus sabdariffa)
- sesame oil (Sesamum indicum)
- tomato extract (Lycopersicon esculentum)
- tea (Camellia sinensis), especiallygreen teaandoolong tea
- umbrella tree bark (Musanga cecropioides)
Your blood pressure typically dips down when you’re sleeping. If you don’t sleep well, it can affect your blood pressure.
People who experiencesleep deprivation, especially those who are middle-aged, have an increased risk of high blood pressure (
对一些人来说,获得一个良好的睡眠是“t easy. These are some of the many ways to help youget restful sleep(
- Try setting a regular sleep schedule.
- Spend time relaxing before bedtime.
- Exercise during the day.
- Avoid daytime naps.
- Make your bedroom comfortable.
The 2010 national Sleep Heart Health Study found that regularly sleeping fewer than 7 hours a night and more than 9 hours a night was associated with an increased rate of high blood pressure.
Regularly sleeping fewer than 5 hours a night was linked to a significant risk of high blood pressure long term (29).
Freshgarlicor garlic extract are both widely used to lower blood pressure.
A meta-analysis found that for people with high blood pressure, garlic supplements reduced their systolic blood pressure by up to about 5 mm Hg and reduced their diastolic blood pressure as much as 2.5 mm Hg (
According to a 2009 clinical study, a time-release garlic extract preparation may have a greater effect on blood pressure than regular garlic powder tablets (31).
A long-term study concluded in 2014 found that people who ate more protein had a lower risk of high blood pressure. For those who ate an average of 100 grams of protein per day, there was a 40 percent lower risk of having high blood pressure than those on a low protein diet (32).
Those who also added regularfiberinto their diet saw up to a 60 percent reduction of risk.
However, ahigh protein dietmay not be for everyone. Those with kidney disease may need to use caution. It’s best to talk with your doctor.
It’s fairly easy to consume 100 grams of protein daily on most types of diets.
High protein foodsinclude:
- fish, such assalmonorcanned tunain water
- eggs
- poultry, such aschicken breast
- beef
- beans andlegumes, such askidney beansandlentils
- nutsornut butter, such aspeanut butter
- chickpeas
- cheese, such as cheddar
A 3.5-ounce serving of salmon can have as much as 22 grams of protein, while a 3.5-ounce serving of chicken breast might contain 30 grams of protein.
With regard to vegetarian options, a half-cup serving of most types of beans contains 7 to 10 grams of protein. Two tablespoons of peanut butter would provide 8 grams (33).
These supplements are readily available and have demonstrated promise for lowering blood pressure:
Omega-3 polyunsaturated fatty acid
Addingomega-3 polyunsaturated fatty acidsorfish oilto your diet can have many benefits.
A meta-analysis of fish oil and blood pressure found a mean blood pressure reduction in those with high blood pressure of 4.5 mm Hg systolic and 3.0 mm Hg diastolic (34).
Whey protein
This proteincomplex derived from milk may have several health benefits in addition to possibly lowering blood pressure (
Magnesium
缺镁is related to higher blood pressure. A meta-analysis found a small reduction in blood pressure withmagnesiumsupplementation (36).
Citrulline
Oral L-citrullineis a precursor toL-argininein the body, a building block of protein, which may lower blood pressure (
Alcoholcan raise your blood pressure, even if you’re healthy.
It’s important to drink in moderation. According to a 2006 study, alcohol can raise your blood pressure by 1 mm Hg for each 10 grams of alcohol consumed (38). A standard drink contains 14 grams of alcohol.
What constitutes a standard drink? One 12-ounce beer, 5 ounces of wine, or 1.5 ounces of distilled spirits (
Moderate drinking is up to one drink a day for women and up to two drinks per day for men (
A review found that although drinking more than 30 grams of alcohol may initially lower blood pressure, after 13 hours or more, systolic blood pressure increased by 3.7 mm HG and diastolic blood pressure increased by 2.4 mm Hg (41).
Caffeine raises your blood pressure, but theeffectis temporary.
In a 2017 study, the systolic blood pressure of 18 participants was elevated for 2 hours after they drank 32 ounces of either a caffeinated drink or an energy drink. Blood pressure then dropped more quickly for the participants who drank a caffeinated drink (
Some people may be more sensitive to caffeine than others. If you’re caffeine-sensitive, you may want to cut back on your coffee consumption, or trydecaffeinated coffee.
Research oncaffeine, including its health benefits, is in the news a lot. The choice of whether to cut back depends on many individual factors.
One older study indicated that caffeine’s effect on raising blood pressure is greater if your blood pressure is already high. This same study, however, called for more research on the subject (43).
If your blood pressure is very high or doesn’t decrease after making these lifestyle changes, your doctor may recommendprescription drugs.
They work and will improve your long-term outcome, especially if you have other risk factors (
Talk with your doctor about possible medications and what might work best for you.
