High blood pressure is the most common heart risk factor in men over 35, and most men who have it feel completely fine. The encouraging part is how responsive it is: a few specific changes to food, training, alcohol and sleep can lower your numbers by amounts that rival a single medicine. Here is how to lower blood pressure naturally, using the changes with the strongest evidence behind them.
Key takeaways
- Under US guidelines, 130/80 or higher counts as high blood pressure. Confirm it with home readings before drawing conclusions.
- In the DASH-Sodium trial, combining the DASH diet with lower sodium cut systolic pressure by 11.5 mmHg in people with hypertension.
- Aim for under 2,300 mg of sodium a day, ideally closer to 1,500 mg, and eat more potassium-rich foods.
- Isometric exercise such as wall squats and handgrip holds produced the largest average blood pressure drop in a 270-trial analysis. Aerobic and strength training also help.
- Each kilogram of weight lost lowers blood pressure by about 1 mmHg. Cutting back heavy drinking and treating sleep apnea also matter.
- Whether you need medication, and which one, is a decision for you and your doctor.
Know your category first
The 2025 American Heart Association and American College of Cardiology guideline kept the same categories it introduced in 2017. The top number (systolic) and bottom number (diastolic) are judged separately. Whichever falls in the higher category sets your category.
| Category | Systolic (top) | Diastolic (bottom) | Typical first step | |
|---|---|---|---|---|
| Normal | Below 120 | and | Below 80 | Keep healthy habits |
| Elevated | 120–129 | and | Below 80 | Lifestyle changes |
| Stage 1 hypertension | 130–139 | or | 80–89 | Lifestyle changes for 3–6 months; medicine if higher risk |
| Stage 2 hypertension | 140 or higher | or | 90 or higher | Lifestyle changes plus medication, per your doctor |
Under the 2025 guideline, people with stage 1 blood pressure and no heart disease, diabetes or kidney disease usually start with lifestyle changes for three to six months. Medicine is recommended if readings stay at 130/80 or above. Your doctor may advise medicine sooner if your estimated 10-year risk is high.
Step 1: Measure properly at home
A single reading at the clinic can be pushed up by nerves, a rushed walk from the car park or a full bladder. Guidelines recommend confirming the diagnosis with readings taken outside the office. Home readings also pick up “masked” hypertension, which is normal at the clinic but high at home.
The American Heart Association’s tips for accurate readings:
- Use a validated upper-arm monitor with a cuff that fits your arm. You can check models on validatebp.org.
- Avoid caffeine, exercise and smoking for 30 minutes beforehand, and empty your bladder.
- Sit quietly for five minutes with your back supported, feet flat and legs uncrossed. Do not use your phone.
- Put the cuff on your bare upper arm, resting on a table at heart level, and do not talk.
- Take two readings at least a minute apart, morning and evening, for a week. Then average them.
Step 2: Eat the DASH way
DASH (Dietary Approaches to Stop Hypertension) is the best-tested eating pattern for blood pressure. It is rich in vegetables, fruit, whole grains, legumes, nuts and low-fat dairy, and light on red and processed meat, sweets and sugary drinks.
In the DASH-Sodium trial, 412 adults ate a typical American diet or the DASH diet at three sodium levels. Compared with the typical diet at high sodium, DASH with low sodium lowered systolic pressure by 7.1 mmHg in people without hypertension and 11.5 mmHg in people with it.
DASH is easy to adapt for vegetarians and for Indian or Latin American kitchens:
- Fill half your plate with vegetables: sabzi, salads, grilled peppers, greens.
- Use beans, lentils, chickpeas, tofu, paneer or eggs as your main protein. Our guide to muscle-building foods lists more options.
- Swap refined flour and white rice for whole wheat, brown rice, millets or oats where you can.
- Use plain curd or yogurt and milk for dairy, and nuts or seeds for snacks.
Step 3: Less sodium, more potassium
The 2025 guideline recommends keeping sodium under 2,300 mg a day, ideally under 1,500 mg. That is roughly one teaspoon of salt in total, and most of it comes from packaged and restaurant food rather than the salt shaker.
The biggest sources tend to be bread, pickles and papad, instant noodles, chips and namkeen, processed meat and cheese, sauces and stock cubes, and takeaway meals. Reading labels and cooking at home more often makes the biggest difference.
Potassium works in the opposite direction. Good sources include beans and lentils, potatoes and sweet potatoes, leafy greens, tomatoes, bananas, oranges, yogurt and coconut water.
The guideline also recommends potassium-enriched salt substitutes. In the Salt Substitute and Stroke Study, almost 21,000 older adults in rural China with high blood pressure or a past stroke used a salt substitute containing potassium. Compared with regular salt, it lowered systolic pressure by about 3.3 mmHg and cut stroke by 14%.
Safety note: Potassium salt substitutes and potassium supplements are not safe for everyone. Avoid them unless your doctor approves if you have kidney disease, or if you take medicines that raise potassium, such as ACE inhibitors, ARBs, potassium-sparing diuretics or spironolactone. Do not stop or adjust blood pressure medication on your own, even if your home readings improve. A reading of 180/120 or higher, or high blood pressure with chest pain, breathlessness, severe headache, vision changes, weakness or confusion, needs emergency care.
Step 4: Train for lower blood pressure
A 2023 network meta-analysis in the British Journal of Sports Medicine pooled 270 randomised trials and almost 16,000 people. It compared how much each type of exercise lowered resting blood pressure against no exercise:
| Exercise type | Average systolic drop | Average diastolic drop |
|---|---|---|
| Isometric (wall squats, handgrip, planks) | 8.2 mmHg | 4.0 mmHg |
| Combined aerobic + resistance | 6.0 mmHg | 2.5 mmHg |
| Dynamic resistance (weights) | 4.6 mmHg | 3.0 mmHg |
| Aerobic (walking, running, cycling) | 4.5 mmHg | 2.5 mmHg |
| High-intensity interval training | 4.1 mmHg | 2.5 mmHg |
How to add isometric work
The trials typically used four 2-minute holds with 1–4 minutes of rest, three times a week. Handgrip trials commonly used about 30% of maximum grip strength. For wall squats, a self-selected knee angle was often used, with effort rising from moderate on the first hold to very hard on the fourth.
The authors urge caution because only a few wall-squat trials existed. Treat isometrics as an add-on to aerobic and strength training, not a replacement. Breathe steadily throughout. Never hold your breath during a hold, because that spikes blood pressure.
Keep your aerobic and strength base
For overall heart health, aim for at least 150 minutes of moderate activity a week plus two or more strength sessions. Easy zone 2 training builds your aerobic base, and our guide to strength training after 35 shows how to lift safely. If your blood pressure is in stage 2, get your doctor’s clearance before heavy lifting or maximal efforts.
Step 5: Lose some weight around the middle
A meta-analysis of 25 randomised trials in the journal Hypertension found that each kilogram of weight lost lowered systolic and diastolic pressure by roughly 1 mmHg each. Losing 5 kg can therefore be worth about 5 mmHg. The 2025 guideline strongly recommends weight loss for people with overweight. A steady approach that protects muscle, like the one in our lose fat, keep muscle guide, works best.
Step 6: Rethink alcohol
The 2025 guideline recommends no alcohol or as little as possible, and no more than two drinks a day for men who do drink. A 2017 meta-analysis in The Lancet Public Health found that cutting back did not noticeably lower blood pressure in people who drank two drinks a day or fewer. In heavy drinkers having six or more a day, halving their intake lowered systolic pressure by about 5.5 mmHg. If weekends involve a lot of drinks, that is a clear place to start.
Step 7: Check your sleep for apnea
Obstructive sleep apnea, where the airway repeatedly closes during sleep, is common in people with high blood pressure. An American Heart Association scientific statement puts its prevalence as high as 40–80% in people with hypertension, and recommends screening anyone whose blood pressure is resistant or poorly controlled.
Warning signs include loud snoring, pauses in breathing that a partner notices, waking up choking or gasping, morning headaches and daytime sleepiness. If that sounds familiar, ask your doctor about a sleep study. General sleep habits matter too, and our guide to sleeping better after 35 covers them.
Step 8: Manage stress
The 2025 guideline also includes mindfulness and meditation among its recommended approaches. Ten minutes of breathing practice or a daily walk without your phone will not replace the steps above, but it is low-cost and helps you stick with them.
Where medication fits
Lifestyle changes help everyone, including people already on medication. They can mean a lower dose, fewer drugs or better control. But they do not always bring blood pressure down far enough, and stage 2 readings or high overall risk usually call for medicine from the start. Your doctor will weigh your readings, kidney function, other conditions and preferences. Bring your home readings log to the visit.
FAQ
How quickly can I lower my blood pressure naturally?
In the DASH-Sodium trial, each diet period lasted 30 days and blood pressure changes were clear within that time. Exercise trials typically lasted several weeks or more. Expect to see a trend within a month or two of consistent change.
Is 130/85 high for a 40-year-old man?
Under US guidelines it counts as stage 1 hypertension, because the bottom number is between 80 and 89. Confirm it with a week of home readings, then discuss it with your doctor.
Are wall sits safe if I have high blood pressure?
Blood pressure rises during any hard effort. If your readings are in stage 2 or you have heart disease, get your doctor’s clearance first, start with shorter and easier holds, and never hold your breath.
Does coffee raise blood pressure?
Caffeine can raise blood pressure briefly, which is why you should avoid it for 30 minutes before measuring. Ask your doctor if your readings are high and you drink a lot of coffee.
Can I stop my medication once my numbers improve?
Not on your own. Share your home readings with your doctor, who can decide whether a dose change is safe.
