You can lower blood pressure naturally by keeping a healthy weight, eating more vegetables and fruit, cutting down on salt, being active most days, limiting alcohol, not smoking and sleeping well. These habits can bring readings down by several points each, and together they also support any medicine your doctor prescribes.
What counts as high blood pressure?
The World Health Organization (WHO) says hypertension is diagnosed when readings taken on two different days show a systolic (top) number of 140 mmHg or more and/or a diastolic (bottom) number of 90 mmHg or more. Some countries and guidelines use different cut-offs, so ask your doctor what your own target is.
About 1.4 billion adults aged 30 to 79 had hypertension in 2024, and the WHO estimates that around 44% of them did not know it. Because it is usually silent, the only reliable way to find out is to have your blood pressure measured.
How to lower blood pressure naturally: 9 steps
1. Lose extra weight, if you need to
Mayo Clinic notes that blood pressure may fall by about 1 mmHg for every kilogram lost. Waist size matters too: more than 102 cm (40 inches) in men or 89 cm (35 inches) in women raises risk.
2. Eat more vegetables, fruit and whole grains
A healthy eating pattern such as the DASH or Mediterranean diet may lower the top number by up to 11 mmHg, according to Mayo Clinic. Fill half your plate with vegetables, choose fish, beans and nuts more often, and cut down on fatty and processed meats.
3. Cut down on salt
Mayo Clinic advises no more than 2,300 mg of sodium a day, and 1,500 mg or less for most adults, which may lower blood pressure by about 5 to 6 mmHg. The NHS advises avoiding salty foods and not adding salt to meals.
- Taste before you add salt, soy sauce, fish sauce or seasoning mixes.
- Limit instant noodles, canned and cured meats, chips and salty sauces.
- Read food labels and compare sodium between brands.
- Flavour food with garlic, onion, ginger, calamansi or lemon, herbs and pepper instead.
4. Move more and sit less
The WHO recommends at least 150 minutes of moderate aerobic activity (or 75 minutes of vigorous activity) a week, plus muscle-strengthening on 2 or more days. Mayo Clinic says regular aerobic exercise may lower blood pressure by about 5 to 8 mmHg. Brisk walking, cycling, swimming and dancing all count.
5. Limit alcohol
The NHS advises not regularly drinking more than 14 units a week, and Mayo Clinic suggests one drink a day or less, with alcohol-free days. If you do not drink, there is no need to start.
6. Stop smoking and vaping
Tobacco and nicotine raise the risk of heart disease and stroke. Avoid second-hand smoke too, and ask your health centre about stop-smoking support.
7. Sleep 7 to 9 hours
Mayo Clinic notes that regularly getting fewer than 7 hours of sleep over weeks can affect blood pressure. Shift workers can help by keeping a dark, quiet sleep space and a regular pre-sleep routine, and by avoiding caffeine close to bedtime.
8. Manage stress
Long-term stress can make healthy habits harder. Try slow breathing, short walks, time with supportive people or meditation. If work stress is building, our guide to the signs of nurse burnout may help.
9. Check your blood pressure at home and keep your appointments
Home blood pressure monitors are sold without a prescription and help you and your doctor see whether your changes are working. Follow the monitor’s instructions, write down each reading with the date and time, and bring the record to your check-ups.
If you already take blood pressure medicine
Lifestyle changes work alongside medicine, not instead of it. The WHO advises taking medicines as prescribed, not missing or sharing doses and keeping follow-up appointments. Tell your doctor if you have side effects, rather than stopping on your own.
When to get medical help
See a doctor or nurse to have your blood pressure checked if you have never had it measured, if home readings are often 140/90 or higher, or if you have diabetes, kidney disease or a family history of heart disease.
Seek emergency care immediately if your blood pressure is very high (the WHO mentions 180/120 or higher) and you have any of these:
- Chest pain
- Difficulty breathing
- Severe headache, confusion or vision changes
- An irregular heartbeat
- Sudden weakness or numbness of the face, arm or leg, or trouble speaking (possible stroke)
Frequently asked questions
How fast can you lower blood pressure naturally?
There is no fixed timeline, and the benefit lasts only while you keep the habits. Blood pressure also changes during the day, so one reading tells you little. Track your home readings over several weeks, look at the overall trend, and review it with your doctor or nurse at your next check-up.
Does drinking water lower blood pressure?
Staying well hydrated is part of good health, but water alone is not a proven treatment for high blood pressure. The changes with the strongest evidence are weight loss if needed, a lower-salt diet rich in vegetables and fruit, regular activity, less alcohol and not smoking. Ask your doctor about fluid limits if you have heart or kidney disease.
Can I stop my blood pressure medicine if my readings are normal?
No, not on your own. Normal readings often mean the medicine is working. Stopping suddenly can make blood pressure rise again. If your readings stay low or you feel dizzy, talk to your doctor, who may adjust or reduce the dose safely while you continue the healthy habits.
