Preventing hypertension: How to reduce the risk of high blood pressure

Arterial hypertension doesn't develop overnight: it's often the result of a long-term combination of hereditary predisposition, a diet high in salt, low physical activity, weight gain, chronic sleep deprivation, stress, alcohol, smoking, and age-related vascular changes. Therefore, prevention should begin not when blood pressure is already consistently above normal, but earlier—with elevated or borderline blood pressure, a family history, diabetes, chronic kidney disease, excess weight, and other risk factors. [1]

The current 2025 guidelines from the American Heart Association and the American College of Cardiology explicitly consider the prevention, early detection, and treatment of high blood pressure as a holistic process: first, accurately measure blood pressure, then assess overall risk, and then implement lifestyle changes and, if necessary, promptly initiate medication. This approach is important because even moderately elevated blood pressure increases the risk of stroke, heart attack, heart failure, chronic kidney disease, and cognitive decline over time. [2]

In its 2024 guidelines, the European Society of Cardiology introduced a more understandable category of "high blood pressure" to avoid waiting until a person develops persistent hypertension. This reflects a modern understanding of risk: blood vessels, the heart, kidneys, and brain respond not only to an "official diagnosis" but also to years of living with blood pressure above the optimal level. [3]

Prevention doesn't mean abandoning medical monitoring. On the contrary, it includes regular blood pressure measurements, cardiovascular risk assessment, glucose and lipid metabolism testing, kidney function monitoring, and discussing a personalized strategy with a doctor. In 2026, the UK's National Institute for Health and Care Excellence specifically recommended providing healthy lifestyle advice to people with high blood pressure even when a diagnosis of hypertension has not yet been confirmed. [4]

The basic idea of prevention is simple: the sooner you reduce the load on your blood vessels, the less likely you are to need intensive treatment later. But "simple" prevention should be concrete: not abstract "less salt and more exercise," but clear goals for sodium, body weight, activity, alcohol, sleep, stress, and home blood pressure monitoring. [5]

Prevention direction	Practical purpose	Why is this important?
Regular blood pressure measurement	Know your normal values, not 1 random number	Allows to identify the risk of complications
Reducing salt	Less than 2,000 milligrams of sodium per day, as recommended by the World Health Organization	Salt increases blood pressure and vascular risk
Diet based on the principles of "Dietary approaches to stopping hypertension"	More vegetables, fruits, whole grains, legumes, fish, low-fat dairy products	This diet helps lower blood pressure.
Physical activity	At least 150 minutes of moderate activity per week and strength training 2 days per week	Improves vascular function and helps control weight
Weight	In case of excess body weight, a reduction of at least 5%	Even moderate weight loss helps blood pressure
Alcohol	It's better to refuse, or at least reduce consumption.	Alcohol increases blood pressure
Sleep and stress	Regular sleep and managed stress	Lack of sleep and chronic stress worsen blood pressure control

Who especially needs prevention?

Prevention is essential for all adults, but it's especially important for those whose blood pressure is already above the optimal range. Even if a doctor hasn't yet diagnosed hypertension, repeated readings above 120 over 80 mmHg require attention: this isn't a sign of panic, but rather a signal for early intervention. The 2025 guidelines define normal blood pressure as below 120 and 80, elevated blood pressure as 120-129 and below 80, and stage 1 hypertension as 130-139 or 80-89. [8]

Particular attention is needed for people with a family history of early strokes, heart attacks, or hypertension. Heredity cannot be changed, but the influence of modifiable factors can be reduced: salt intake, body weight, physical inactivity, alcohol, smoking, sleep deprivation, and poor diabetes control. Therefore, prevention should not be viewed as "general advice," but as a way to compensate for the innate vulnerability of the vascular system. [9]

Overweight and obese individuals are at increased risk because increased body fat is associated with insulin resistance, chronic inflammation, sympathetic nervous system activation, sodium retention, and increased cardiac strain. The 2025 guidelines recommend weight loss for adults with high blood pressure or hypertension, and for those who are overweight or obese, the practical goal is a weight loss of at least 5%. [10]

Diabetes mellitus, chronic kidney disease, lipid metabolism disorders, and existing cardiovascular disease dramatically increase the significance of even moderately elevated blood pressure. The UK's National Institute for Health and Care Excellence recommends assessing cardiovascular risk for hypertension, testing urine for albumin, blood for creatinine, estimated glomerular filtration rate, glycated hemoglobin, total cholesterol, and high-density lipoprotein cholesterol. [11]

A separate group includes pregnant and post-pregnancy women, especially those with a history of gestational hypertension or preeclampsia. The American College of Cardiology notes that the new 2025 guidelines place greater emphasis on high blood pressure during pregnancy because it is associated with the risk of complications during pregnancy itself and with the mother's future cardiovascular risk. [12]

A group of people	Why is the risk higher?	What to do as a preventative measure
Pressure 120-129 and below 80	This is no longer the optimal level.	Measure regularly, reduce salt, increase activity
Pressure 130-139 or 80-89	Corresponds to stage 1 hypertension in the American classification	Assess the risk and begin intensive lifestyle changes
Overweight	Weight increases vascular and metabolic stress	The goal is to lose at least 5% of your weight.
Diabetes mellitus	High blood pressure damages kidneys and blood vessels faster.	Control of blood pressure, sugar, kidneys and lipids
Chronic kidney disease	Kidneys and blood pressure increase each other's damage.	Monitoring of urine albumin, creatinine and potassium
Family history of early vascular events	Some of the risk is inherited.	Start prevention and measurements earlier
Pregnancy or hypertension in pregnancy in the past	The risk of complications and future hypertension is higher	Observation by a doctor and blood pressure monitoring

Nutrition: The Main Daily Tool for Prevention

Diet affects blood pressure every day because it determines the intake of sodium, potassium, saturated fat, dietary fiber, magnesium, calcium, and total calorie intake. The most studied diet for the prevention and treatment of high blood pressure is the "Dietary Approaches to Stop Hypertension" plan: it is based on vegetables, fruits, whole grains, low-fat dairy products, fish, poultry, legumes, nuts, and vegetable oils. [15]

This diet doesn't require special foods, health cocktails, or expensive supplements. Its purpose is to replace a diet high in salt, processed meats, sugary drinks, high-fat dairy, and saturated fats with a sustainable eating pattern that can be maintained for years. The National Heart, Lung, and Blood Institute (NHLBI) recommends the Dietary Approaches to Stop Hypertension plan as a flexible and balanced way to promote heart health. [16]

Salt is one of the most powerful dietary stressors. The World Health Organization recommends that adults consume less than 2,000 milligrams of sodium per day, which equates to less than 5 grams of salt. Meanwhile, the average global sodium intake for adults in 2021 was estimated at 4,278 milligrams per day, more than twice the recommended level. [17]

Most sodium often comes not from the salt shaker, but from bread, processed meats, snacks, sauces, prepared foods, cheese, canned goods, ready-made meals, and restaurant food. Therefore, prevention involves not only "undersalting" but also reading labels, choosing foods with less sodium, cooking more often at home, and gradually adjusting your taste buds so that less salty foods don't taste bland. [18]

Potassium helps counteract the harmful effects of sodium, but it's safer to get it from food sources: vegetables, fruits, legumes, potatoes, leafy greens, nuts, and dairy products. The World Health Organization recommends increasing dietary potassium intake to reduce blood pressure and the risk of cardiovascular disease, but people with chronic kidney disease or medications that reduce potassium excretion should not switch to potassium salts or supplements without consulting a doctor. [19]

Power supply component	What to do	Practical example
Salt and sodium	Aim for less than 2,000 milligrams of sodium per day	Less sauces, sausages, snacks, salty cheeses and processed foods
Vegetables	Eat daily	Add vegetables to 2-3 meals
Fruits	Use as a dessert or snack	Apples, berries, citrus fruits, bananas, unless there are contraindications
Whole grains	Replace refined carbohydrates	Oatmeal, buckwheat, whole grain bread
Legumes	Turn on several times a week	Beans, lentils, chickpeas, peas
Low-fat protein foods	Prefer fish, poultry, legumes	Less processed meat
Saturated fats	Limit	Less fatty meat, butter, and fatty dairy products
Sweet drinks	To shorten	Water, unsweetened tea, sugar-free drinks

Salt, Salt Substitutes, and Potassium: Benefits and Risks

Reducing salt is one of the most proven ways to prevent high blood pressure at the individual and societal levels. The World Health Organization considers sodium reduction a priority public health measure and recommends reformulating products, introducing front-of-pack labeling, improving nutrition in schools, hospitals, and workplaces, and conducting information campaigns. [23]

The 2025 U.S. guidelines recommend reducing sodium intake to less than 2,300 milligrams per day and, if possible, moving toward an ideal level of less than 1,500 milligrams per day. For the average person, this means prevention begins at the store: the more processed foods in the diet, the more difficult it is to keep sodium within a safe range. [24]

Potassium-containing salt substitutes may be beneficial if the bulk of the salt is added at home during cooking or at the table. In 2025, the World Health Organization conditionally recommended replacing regular table salt with low-sodium substitutes containing potassium for adults in the general population, but excluded pregnant women, children, people with impaired kidney function, and those with conditions that impair potassium excretion. [25]

This caveat is crucial: potassium is not beneficial for everyone, and not in every form. In people with chronic kidney disease, taking certain blood pressure medications, such as angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, and in some cardiac and endocrine conditions, excess potassium can be dangerous. Therefore, potassium salt and potassium supplements cannot be considered a "safe replacement for everyone." [26]

The best first step isn't to add new supplements, but to reduce sodium and increase whole foods. Eating more vegetables, legumes, fruits, and whole grains typically reduces sodium, increases potassium, and increases fiber, making blood pressure prevention more sustainable. [27]

Strategy	Who is it suitable for?	Restrictions
Less regular salt	Almost all adults	It is necessary to take into account hidden salt in prepared foods.
Reading labels	To everyone who buys prepared foods	Requires the habit of comparing sodium per 100 grams
Homemade food	Especially with high consumption of processed foods	You need to plan your shopping and cooking.
Herbs and spices instead of salt	Almost everyone	It is important to avoid ready-made mixtures with salt
Potassium-containing salt	Some adults without risk of potassium retention	Do not take if you have kidney disease or certain medications without a doctor's advice.
Potassium from food	For most people	Chronic kidney disease requires an individualized plan
Potassium supplements	For medical reasons only	Self-administration can be dangerous.

[28] [29] [30]

Physical activity and weight

Physical activity reduces the risk of hypertension not only through calorie expenditure. It improves vascular endothelial function, increases insulin sensitivity, helps control body weight, reduces vascular stiffness, improves sleep, and reduces stress reactivity. The US Centers for Disease Control and Prevention recommends that adults get at least 150 minutes of moderate aerobic activity per week or 75 minutes of vigorous-intensity activity, as well as muscle-strengthening exercise at least two days per week. [31]

Preventing hypertension doesn't require jumping straight into running or the gym. Brisk walking, cycling, swimming, dancing, active gardening, stair climbing, and regular short walks are all beneficial if done systematically. The Centers for Disease Control and Prevention (CDC) emphasizes that the 150 minutes can be spread out over the week and broken down into smaller segments. [32]

Strength training is also important: it maintains muscle mass, improves glucose metabolism, and helps with weight management. The 2025 guidelines indicate that a structured activity program for the prevention and treatment of high blood pressure may include aerobic and resistance exercise. [33]

Weight control is a key pillar of prevention. If you're overweight, even a 5% weight loss can improve your blood pressure and overall metabolic profile. This is a practical goal: for someone weighing 100 kilograms, it's not about reaching an immediate "ideal weight," but rather the first 5 kilograms, which can have clinical significance. [34]

The most sustainable strategy is a combination of moderate calorie reduction, a diet based on the principles of the "Dietary Approaches to Stopping Hypertension," increased daily activity, and regular strength training. Extreme diets, severe dehydration, uncontrolled use of diuretics, and weight-loss stimulants do not prevent hypertension and can be dangerous. [35]

Target	Minimum benchmark	How to start safely
Aerobic activity	150 minutes of moderate exercise per week	30 minutes of brisk walking 5 days a week
Intense activity	75 minutes a week	Only with sufficient preparation and no contraindications
Strength exercises	2 days a week	Exercises with your own weight, bands, or light weights
Less sitting	Breaks every 30-60 minutes	2-5 minutes of walking or light exercise
Weight loss	Minimum 5% for overweight	Gradually, without extreme diets
Long-term goal	Stable habits	Activity that can be maintained for years

Source for table: Physical activity and weight loss guidelines are based on the CDC's 2025 guidelines for high blood pressure.[36] [37]

Alcohol, smoking, caffeine, sleep and stress

Alcohol increases blood pressure dose-dependently and worsens control of existing hypertension. The 2025 guidelines recommend that people with high blood pressure or hypertension strive to abstain from alcohol, and if they continue to drink, at least reduce their consumption to no more than one standard drink per day for women and no more than two standard drinks per day for men. [38]

Smoking and nicotine don't always result in a sustained increase in blood pressure, but they do dramatically increase overall cardiovascular risk, damage vascular walls, and increase the likelihood of heart attack, stroke, and peripheral atherosclerosis. The UK's National Institute for Health and Care Excellence recommends that people with hypertension receive advice and support to quit smoking. [39]

Caffeine's effects vary from person to person: in some people, it causes a noticeable, short-term increase in blood pressure, especially with large doses, anxiety, lack of sleep, or infrequent coffee consumption. Therefore, a preventative approach doesn't require complete abstinence from coffee for everyone, but it does suggest avoiding excessive consumption of coffee and other caffeinated products, especially if they consistently increase blood pressure. [40]

Sleep is an underrated element of prevention. During normal sleep, blood pressure physiologically decreases, but with sleep problems, it remains elevated longer. The US Centers for Disease Control and Prevention notes a link between insomnia and high blood pressure and heart disease, and obstructive sleep apnea is associated with an increased risk of hypertension, heart attack, and stroke. [41]

Stress itself is not always the sole cause of hypertension, but it impairs behavior, sleep, nutrition, alcohol consumption, and treatment adherence. The 2025 guidelines allow the use of stress management techniques—meditation, breathing techniques, or yoga—as an adjunct to core preventive measures, but not as a substitute for salt control, weight management, physical activity, and medical monitoring. [42]

Factor	How does it affect blood pressure?	Preventive tactics
Alcohol	May increase blood pressure and interfere with control	Better to refuse, at least a strict restriction
Smoking and nicotine	Increase vascular risk	Complete cessation, doctor's help for addiction
Excess caffeine	In some people it causes a short-term increase in blood pressure.	Assess individual response and avoid excess
Lack of sleep	Blood pressure remains elevated for longer	Regular sleep and treatment of sleep disorders
Sleep apnea	Increases the risk of hypertension, heart attack and stroke	Examination for snoring, respiratory arrest and drowsiness
Chronic stress	Increases bad habits and vascular reactivity	Physical activity, breathing exercises, psychotherapeutic support if necessary

Measuring blood pressure as part of prevention

Prevention is impossible without knowing your numbers. High blood pressure often causes no symptoms, so a person can feel fine for years while their blood vessels, heart, kidneys, and brain are already under excessive strain. The World Health Organization explicitly includes regular blood pressure monitoring as part of measures to reduce the risk of hypertension. [46]

Home monitoring is beneficial not only for people with a confirmed diagnosis, but also for those whose blood pressure periodically rises in the doctor's office, who have a family history, or who already have risk factors. The American Heart Association, in its 2025 guidelines, recommends home monitoring to confirm office diagnoses, track progress, and tailor treatment plans. [47]

For measurements to be useful, they must be accurate. The UK's National Institute for Health and Care Excellence recommends that when confirming hypertension at home, two consecutive measurements should be taken at least 1 minute apart, while seated, morning and evening, for at least four days, preferably seven, then excluding the first day and averaging the remaining values. [48]

If a diagnosis of hypertension is not confirmed, but blood pressure remains elevated, measurements should not be neglected for years. British guidelines recommend measuring clinical blood pressure at least every 5 years, and if blood pressure is below 140/90 but still elevated, consider more frequent measurements. [49]

It's important to understand when prevention is no longer sufficient. If average blood pressure values are persistently elevated, or if diabetes, chronic kidney disease, target organ damage, or high cardiovascular risk are present, a doctor may recommend drug therapy in conjunction with lifestyle interventions. The 2025 guidelines indicate that for blood pressure levels of 130-139 or 80-89 in people with a low 10-year risk, drug therapy is considered if, after 3-6 months of lifestyle intervention, the blood pressure remains above the target. [50]

Situation	What to do
The pressure is usually below 120 and 80	Continue prevention and measure periodically
Pressure 120-129 and below 80	Strengthen your lifestyle and monitor your progress
Pressure 130-139 or 80-89	Assess the overall risk and initiate systemic prevention
Office pressure 140 to 90 and higher	Confirm with home or daily monitoring
High blood pressure plus diabetes or kidney disease	Do not delay medical evaluation
Blood pressure 180 to 120 or higher with symptoms	Urgent medical attention is needed

Source for table: The approach to monitoring, confirming blood pressure and early intervention is based on the UK National Institute for Health and Care Excellence (NIH) recommendations and the 2025 high blood pressure guidance. [51] [52]

Prevention in Real Life: How to Turn Recommendations into a System

The most common cause of failure is trying to change everything at once. A person suddenly cuts out salt, starts intense workouts, goes on a strict diet, sleeps poorly, and then returns to their old routine after two weeks. A more reliable approach is to choose two or three initial steps: for example, measuring blood pressure for one week, eliminating the saltiest foods, and adding 30 minutes of walking five days a week. [53]

The second principle is to measure not only blood pressure but also habits. If a person doesn't know how much salt they're getting from bread, cheese, sausage, sauces, and prepared meals, they may genuinely consider their diet "unsalted," even though sodium remains high. The World Health Organization points out that sodium is often found in high quantities in processed foods, bread, processed meats, snacks, and sauces. [54]

The third principle is to consider safety. Potassium salts, intense exercise, rapid weight loss, medication withdrawal, diuretics "for prevention," and potassium supplements can be dangerous in cases of kidney disease, heart rhythm disorders, pregnancy, old age, and the use of certain medications. Therefore, prevention should be medically sound rather than heroic. [55]

The fourth principle is that prevention should be family and household-based. If everyone at home buys salty processed foods, sugary drinks, snacks, and alcohol, it's difficult for one person to maintain a healthy lifestyle. It's much more effective to change the overall grocery basket, cooking methods, portion sizes, evening sleep patterns, and family outings. [56]

The fifth principle is not to pit lifestyle against medication. For some people, lifestyle can indeed delay the development of hypertension or reduce the need for medication, but for others, heredity, age, diabetes, chronic kidney disease, or organ damage require medication support. In such cases, prevention remains essential, but it works in conjunction with treatment, not instead of it. [57]

Stage	Specific action	How to understand that there is progress
Week 1	Measure your blood pressure according to the rules for several days	An understanding of the usual meanings has emerged
Week 2	Find the 3 main sources of salt in the diet	Reduced frequency of processed foods
Week 3	Add walking or other moderate activity	At least 150 minutes of movement per week
Week 4	Improve your sleep and reduce evening alcohol consumption	Fewer nighttime awakenings and morning blood pressure increases
2nd month	Switch to a diet rich in vegetables and legumes	The diet became less salty and richer in potassium
3rd month	Assess your weight, blood pressure, and blood tests with your doctor	Decision: continue prevention or intensify treatment

Frequently asked questions

Is it possible to completely prevent hypertension? For some people, the risk can be significantly reduced or the disease's development delayed, but it's impossible to completely guarantee the absence of hypertension due to age, heredity, kidney disease, endocrine factors, and other factors. Prevention is necessary not because it offers a 100% guarantee, but because it reduces the likelihood of the disease and its complications. [61]

At what pressure should prevention begin? It's best to start not with a diagnosis, but with a deviation from the optimal level: if the pressure is repeatedly above 120 over 80 mmHg, it's time to evaluate salt, weight, activity, sleep, alcohol, and family risk factors. In the 2025 American classification, pressure of 120-129 and below 80 is considered high blood pressure, while 130-139 or 80-89 is considered stage 1 hypertension. [62]

Should you completely eliminate salt? Eliminating sodium completely is impossible and practically unnecessary, but excess sodium should be reduced. The World Health Organization recommends that adults consume less than 2,000 milligrams of sodium per day, which equates to less than 5 grams of salt. [63]

Can you substitute potassium salt for regular salt? Sometimes it's possible, but not for everyone. The World Health Organization conditionally recommends low-sodium salt substitutes with potassium for adults in the general population, but not for children, pregnant women, people with impaired kidney function, or conditions that may impair potassium excretion. [64]

What physical activity is best for preventing high blood pressure? The basic goal is at least 150 minutes of moderate aerobic activity per week or 75 minutes of vigorous-intensity activity, plus muscle-strengthening exercises at least two days a week. For most people, brisk walking is the safest start, gradually increasing the intensity and maintaining regularity. [65]

Will losing weight help if your blood pressure is only slightly elevated? Yes, if you're overweight. The 2025 guidelines recommend weight loss for those with high blood pressure or hypertension, and a practical starting goal for those who are overweight or obese is at least 5% of their starting weight. [66]

Should I take potassium or magnesium supplements for prevention? Taking potassium, magnesium, or calcium supplements on my own to lower blood pressure is not recommended. British guidelines specifically advise against supplementing with calcium, magnesium, or potassium as a method for lowering blood pressure, and it is preferable to obtain potassium from food, taking into account the condition of my kidneys and medications I am taking. [67]

Is coffee prohibited if you're at risk for hypertension? A complete ban on coffee isn't a universal rule, but excessive consumption of coffee and other caffeinated products is not recommended. If your blood pressure rises significantly after drinking coffee, you should reduce your intake, avoid strong coffee during times of stress and sleep deprivation, and discuss the situation with your doctor. [68]

Why is sleep included in blood pressure prevention? During normal sleep, blood pressure decreases, but with insomnia, short sleep, and sleep apnea, it can remain elevated for longer. The US Centers for Disease Control and Prevention links sleep apnea to an increased risk of hypertension, heart attack, and stroke. [69]

When is prevention no longer sufficient and medication is needed? If blood pressure is persistently high, if there is target organ damage, diabetes, chronic kidney disease, previous cardiovascular events, or a high estimated risk, a doctor may recommend medication along with lifestyle changes. The 2025 guidelines for low-risk individuals with blood pressure of 130-139 or 80-89 allow for 3-6 months of intensive lifestyle modification, but if the goal is not achieved, drug treatment is considered. [70]

Key points from experts

Professor John William McEvoy, chair of the European Society of Cardiology's 2024 Guidelines Task Force, advocates an approach that views elevated blood pressure as an early risk signal rather than a harmless intermediate state. This approach advocates prevention before persistent hypertension, as cardiovascular risk increases gradually. [71]

Daniel W. Jones, MD, chair of the 2025 guidelines writing committee for the American Heart Association and the American College of Cardiology, made the key point: High blood pressure is the most common and most modifiable risk factor for heart disease. This means that preventing it is one of the most practical ways to reduce the future burden of stroke, heart attack, kidney disease, type 2 diabetes, and dementia. [72]

Cian P. McCarthy, MD, coordinator of the European Society of Cardiology's 2024 Guidelines Task Force, is part of the team that updated the European approach to high blood pressure and hypertension based on current evidence. This is important for prevention because the guidelines shift the focus from late treatment of complications to early detection and risk management. [73]

Rosa Maria Bruno, professor and coordinator of the European Society of Cardiology's 2024 Guidelines Task Force, is also among the authors of the document, which considers diagnosis, risk assessment, and lifestyle as interrelated elements in the management of people with high blood pressure. This approach supports prevention as a clinical strategy, rather than as an afterthought. [74]

In the 2026 update, experts from the UK's National Institute for Health and Care Excellence added a recommendation to provide healthy lifestyle advice to people with high blood pressure, even without a confirmed diagnosis of hypertension. This is an important practical shift: preventative counseling should begin at the risk stage, not only after a diagnosis. [75]

Result

Preventing hypertension isn't a single measure, but a system: accurate blood pressure measurement, reduced salt intake, a diet rich in vegetables, fruits, whole grains, and legumes, regular physical activity, weight control, smoking cessation, limiting or eliminating alcohol, normalizing sleep, and stress management. It is the combination of these measures that offers the greatest chance of delaying the development of hypertension and reducing the risk of complications. [76]

The most practical strategy is to start with measurable steps: checking your blood pressure at home according to guidelines, reducing sodium intake, adding 150 minutes of moderate activity per week, achieving at least a 5% weight loss if you're overweight, improving your sleep, and discussing your individual risk with your doctor. If your blood pressure is already persistently elevated, prevention remains essential, but it should be combined with a medical evaluation and, if indicated, medication. [77]
