La High blood pressure is becoming established as the great silent enemy of cardiovascular health, both in Europe and the rest of the world. Data from large studies indicate that, in people who have suffered a heart attack or stroke, almost all had some prior risk factor and, around 95%, had elevated blood pressure before the event.
This problem becomes even more relevant when you consider that High blood pressure is the leading cause of premature death and disability globally. The good news is that the measures to prevent it and keep it under control They are well-known, well-studied, and, when applied consistently, they work. The key is for the population to actually put them into practice.
Guidelines and consensus: the role of lifestyle in hypertension
The main European scientific societies of cardiology and hypertension periodically review the evidence and develop Clinical guidelines that dictate how hypertension should be diagnosed, prevented, and treatedRecent documents, in line with consensuses such as the most up-to-date Argentine one, insist that changes in habits are not an optional complement, but the core of the approach to high blood pressure.
These consensuses highlight that Modifying lifestyle can reduce blood pressure, improve disease control, and enhance the effect of medications.The classic recommendations remain: lose weight when overweight, restrict salt, move more, eat a healthy diet, limit alcohol, and don't smoke. Emerging aspects such as the role of [the following are also important]: microbiota and probiotics, stress management and the influence of noise or air pollution.
In Europe, the European Society of Hypertension guidelines recommend that All people with high blood pressure should receive intensive advice on lifestyle habits.even when medication is necessary. The message is clear: pills alone are not enough if the other factors contributing to the problem are not addressed.
Body weight and salt: two basic pillars for lowering blood pressure
One of the points on which the different guidelines agree is that, when overweight or obesity is present, Losing a few pounds often results in a significant decrease in blood pressure.It is advisable to combine a balanced low-calorie diet with regular physical activity, always adjusted to each person's situation and with realistic goals.
In recent years they have gained prominence Obesity drugs that, in addition to helping with weight loss, also achieve small reductions in blood pressureThese treatments should always be prescribed under close medical supervision and within the context of a comprehensive approach. In cases of severe obesity, bariatric surgery is still considered an effective and lasting option, although not without risks.
In parallel, the Dietary sodium restriction remains a first-line recommendation. It is estimated that limit salt to about 6 grams per day (which is roughly equivalent to one level teaspoon) can reduce several millimeters of mercury in both systolic (the "high") and diastolic (the "low") pressure.
The problem is that most of the sodium doesn't come from the salt shaker, but from the processed and ultra-processed foods: cold cuts, sausages, savory snacks, prepared broths, sauces, crackers, or many types of packaged breadTherefore, in Spain and the rest of Europe, there is an emphasis on promoting home cooking, reading labels, and prioritizing fresh products.
Potassium, the DASH diet, and the role of the microbiota
Along with sodium reduction, there is increasing emphasis on Increase potassium intake from foodexcept in people with advanced kidney disease or a contrary medical indication. Dietary patterns such as the well-known DASH diet—very similar to a well-executed Mediterranean diet—include four or five servings of fruits and vegetables daily, such as oranges, which provides between 1.500 and 3.000 mg of potassium.
Furthermore, more attention is being paid to the Relationship between nutrition, gut microbiota and blood pressure controlThe available evidence indicates that sufficient fiber intake (above 28g per day in women and 38g in hypertensive men) promotes a healthier microbiota and the production of metabolites, such as short-chain fatty acids, with a beneficial effect on blood vessels.
Among the foods rich in fiber and especially beneficial for blood pressure are the oatsLegumes, leafy green vegetables, fresh fruit, nuts, seeds, or avocadoFurthermore, several meta-analyses suggest that incorporating probiotics into the diet can achieve a modest, but measurable, reduction in blood pressure, especially in people with hypertension and type 2 diabetes.
In Europe, these lines fit with the push to dietary patterns based on plant-based foodsminimally processed and high in fiber, which not only help with blood pressure but also with weight, cholesterol and overall metabolic health.
Exercise, alcohol, and tobacco: how much they matter in blood pressure
Another key area is movement. European guidelines propose the following objective: Perform between 150 and 300 minutes of moderate aerobic exercise per week (Brisk walking, cycling, swimming…) or between 75 and 150 minutes if the intensity is vigorous, or an equivalent combination. In addition, muscle-strengthening exercises are performed 2-3 times per week.
Studies show that different types of training—aerobic, dynamic strength, and even isometric exercises— They can provide pressure reductions comparable to some antihypertensive drugsFurthermore, when combined with medication, the effect is usually greater than with drug treatment alone.
Regarding alcohol, large-scale observational data indicate a direct relationship between amount of alcohol consumed and blood pressure readingsTherefore, the recommendations point to moderating alcohol intake as much as possible and even reserving several days a week completely free of alcohol, something especially relevant for people who already have high blood pressure or a high cardiovascular risk.
Tobacco, meanwhile, continues to be listed as the leading cause of preventable death and a powerful accelerator of vascular damageEach cigarette causes a temporary increase in blood pressure for about half an hour and increases blood pressure variability throughout the day. Furthermore, it can reduce the effectiveness of some antihypertensive medications, such as beta-blockers.
The expansion of electronic cigarettes has not solved the problem either: Recent analyses indicate that they acutely raise blood pressure and heart rate.For this reason, experts recommend that anyone with hypertension receive professional advice on quitting smoking and have access to structured smoking cessation programs.
Stress, noise and pollution: less visible but relevant factors
Beyond diet and exercise, cardiovascular research is increasingly paying attention to the role of Chronic psychological stress, anxiety, and emotional overload in hypertensionStress reduction programs based on mindfulness, breathing techniques, or cognitive-behavioral therapy have been shown to achieve small reductions in stress, which can add up when combined with other lifestyle changes.
Activities such as Yoga, certain relaxation techniques, or something as simple as listening to calming music regularly. They seem to help many people better manage their stress, provided they are integrated into a realistic and sustainable routine.
At the same time, other environmental factors are gaining importance, such as traffic noise, continuous exposure to loud sounds, or air pollution in urban areasClinical and experimental studies suggest that these exposures can induce vascular inflammation, endothelial dysfunction (the inner lining of blood vessels), and, over time, contribute to both the increase and maintenance of high blood pressure.
In European cities with high traffic density or frequent episodes of poor air quality, these findings reinforce policies of emissions reduction, low-emission zones and improvements in sound insulation as measures that not only benefit the environment, but also the cardiovascular health of the population.
Antibacterial mouthwashes and the risk of hypertension: what is known
Alongside the classic recommendations, others have emerged in recent years Striking data on the possible relationship between frequent use of antibacterial mouthwashes and the risk of hypertensionSeveral European cardiologists, including the Spaniard José Abellán, have spread concern on social media about the overuse of these products in daily hygiene.
They emphasize that there is scientific literature that It associates the regular use of oral rinses with intense antibacterial action with an increased risk of developing hypertension by up to 80-85%. compared to those who don't use them or only use them occasionally. The most striking thing is that the effect can be observed within minutes of use, and it seems more pronounced with mouthwashes containing chlorhexidine, a widely used antiseptic.
The proposed mechanism has to do with the oral microbiota, nitric oxide and blood pressure regulationSome bacteria in the mouth transform nitrates present in food into nitrites, a key step in the formation of nitric oxide in the body. This compound acts as a vasodilator: it helps relax blood vessels and contributes to maintaining blood pressure within appropriate ranges.
When mouthwashes that indiscriminately "sweep away" oral flora are used, Not only are microorganisms responsible for problems such as gingivitis or halitosis eliminated, but also beneficial bacteria involved in the production of nitric oxide.The result is a lower availability of this vasodilator, with a potential increase in pressure, greater oxidative stress, and more inflammation in the vascular system.
Despite the alarm this may generate, specialists point out that the effects seem reversible: when the continued use of these mouthwashes is discontinued, the oral microbiota tends to recover and with it the blood pressure levels normalize.Furthermore, to date this same risk has not been observed with conventional toothpastes or mouthwashes without aggressive antibacterial action.
How to choose a mouthwash if you have or fear you may have hypertension
Given this evidence, many experts recommend a critical review What type of mouthwash is used daily, especially in people with high blood pressure or cardiovascular riskAn antibacterial mouthwash is one that not only freshens breath or helps protect enamel, but also acts as a powerful antiseptic against most bacteria in the mouth.
In practice, this means paying attention to ingredients such as chlorhexidine (usually indicated for occasional use after surgery or in severe infections), cetylpyridinium chloride (CPC), or triclosanas well as claims on the packaging such as "eliminates 99% of bacteria," "intensive treatment," or "therapeutic use." Unless specifically advised by a dentist or doctor and for limited periods, it is advisable not to make these products a permanent daily habit.
Conversely, for everyday use it would be preferable to opt for Mouthwashes that respect the oral microbiota, without alcohol or harsh antisepticsIts main function should be to strengthen the enamel, help maintain a balanced pH and provide a feeling of freshness, without intending to completely "sterilize" the mouth.
Ingredients such as xylitol, fluoride, certain thermal waters or mild plant extracts These are considered more suitable for everyday use, provided the product doesn't promise extreme antibacterial action. In any case, the cornerstone of oral hygiene remains proper brushing, flossing, and regular dental checkups.
It is important to emphasize that a Good oral health is associated with a lower risk of cardiovascular events. such as myocardial infarction or serious heart infections, so it is not about abandoning hygiene, but about choosing the tools wisely and getting informed if you suffer from hypertension or have other risk factors.
Why does so much hypertension remain uncontrolled?
Despite having clear guidelines and effective treatments, A very high proportion of people with hypertension do not have their blood pressure levels properly controlled.Recent data from large health surveys show that, in developed countries, almost half of the adult population may meet the criteria for high blood pressure and that around 80% of those who suffer from it do not have it well regulated.
Among those with poorly controlled hypertension, A significant number don't even take antihypertensive medicationDespite the fact that it is known to reduce the risk of heart attack, stroke, and kidney damage, many of these patients have health insurance and access to medical care, suggesting that the problem is not solely due to a lack of healthcare resources.
In many cases, the obstacle lies in the lack of information or awareness about one's own illnessRecent studies indicate that a significant number of people with high blood pressure are unaware of it, or do not correctly interpret the readings from the blood pressure monitor.
In addition, changing habits such as Reduce salt, quit smoking, exercise more, lose weight, or moderate alcohol consumption. It's not always easy, and many people give up before seeing results. That's why specialists emphasize supporting the patient, tailoring the treatment to their individual needs, and setting achievable goals.
In Spain and other European countries, a more active approach to screening and follow-up is being promoted, both in primary care and cardiology, with the aim of Detect hypertension as early as possible and reduce the huge number of undiagnosed or poorly treated cases.
Drug treatment and habits: two sides of the same coin
Hypertension experts remind us that Medication and non-pharmacological measures do not compete with each other, but rather complement each other.In a person whose blood pressure is well controlled with one or more drugs, but who maintains other risk factors (smoking, sedentary lifestyle, very salty diet, sustained stress), the overall cardiovascular risk may still be high.
Even when antihypertensive treatment is well adjusted, The risk of suffering an event such as a stroke, heart attack, or heart failure does not disappear completely.This is because, in addition to high blood pressure, other factors such as diabetes and other conditions are often involved. high cholesterolsmoking or family history.
The most effective strategy involves addressing hypertension in a comprehensive way: Control the levels with medication when necessary, apply lifestyle changes sustainable over time and monitor the remaining risk factorsIt's not about becoming obsessed, but about identifying what can be improved and agreeing on a reasonable plan with the healthcare team.
In this context, seemingly minor decisions—such as the the type of mouthwash used daily, the noise level at home, or the air quality in the surrounding area— they are beginning to be seen as more pieces of the same puzzle. Although some recommendations are supported by stronger evidence than others, they all point in the same direction: taking care of your blood pressure means taking care of your overall health.
Thus, the current picture of hypertension in Spain and Europe shows a complex scenario but with room for maneuver: The risk factors are known, the tools to act exist, and the impact of changing habits, combined with appropriate pharmacological treatment when necessary, can be enormous in terms of quality and life expectancy.To a large extent, it remains to translate this evidence into people's daily lives, from what they eat and drink to how they manage stress, take care of their mouths, or interpret a blood pressure monitor reading at home.
