Warmth with care

WHAT YOU SHOULD CONSIDER WHEN USING A SAUNA IF YOU HAVE HIGH BLOOD PRESSURE

Having high blood pressure doesn’t mean you have to avoid the sauna altogether. In fact, with the right sauna climate, mindful breaks, and gentle cooling down, sauna bathing can support the cardiovascular system, helping the body return to a balanced state without placing it under strain.

Should I go to the sauna with high blood pressure?

Not everything is allowed – but many things are possible

High blood pressure affects over 30 percent of adults making it one of the most significant health risks of our time. In addition to exercise, a healthy diet, and stress reduction, more and more people are discovering the power of heat as a gentle support for high blood pressure. Targeted heat treatments are now considered an effective and natural method for gently regulating blood pressure, without the use of medication, and with noticeable results. Regular sauna use promotes vascular elasticity, activates the cardiovascular system, and supports inner balance. The sauna becomes not just a place of relaxation, but part of a holistic prevention program.

Perhaps you're wondering whether regular sauna use is even advisable for people with high blood pressure, or whether it should be approached with caution. The research is clear, that when used correctly, regular sauna bathing can have positive effects on the cardiovascular system and contribute to long-term blood pressure stabilisation. Gentle saunas, such as the SANARIUM®,have demonstrated particularly convincing results and offer new possibilities such as less stress, more balance.

In this guide, we’ll explain when sauna bathing is suitable for people with high blood pressure, which types of sauna are especially recommended, and what to keep in mind to ensure a safe and beneficial experience. The advice is scientifically supported and practically explained, ideal for those who want to actively and mindfully support their health.

Did you know that regular sauna visits can lower high blood pressure?

A study by the renowned Charité* in Berlin (download PDF with German study) has shown that gentle warmth and a circulatory-friendly climate in the SANARIUM® can lower high blood pressure and alleviate circulatory disorders. Twice-weekly visits to the low-temperature sauna (temperature: 55°C, humidity: 48%) significantly reduced the blood pressure of hypertensive patients, an effect equivalent to that of mild drug therapy.

Is a sauna good for high blood pressure? What science says

The positive effects of sauna baths on the cardiovascular system are now well documented, both in the short term after a sauna session and in the long term with regular use. International studies, such as those from Finland, as well as assessments by the German Hypertension League show that, when used correctly, sauna bathing can be a useful supplement to blood pressure regulation, provided it is individually tailored and practiced responsibly. 

The heat of the sauna triggers a range of physiological responses, many of which are similar to the effects of moderate exercise. If you have high blood pressure and want to enjoy sauna bathing safely, it’s important to understand how these reactions work, and why the benefits are felt after, and not during, your sauna session.

Physical, direct reactions during sauna use:

  • The core body temperature rises to up to 40°C, medically this is referred to as “artificial fever”.
  • The blood vessels under the skin expand (vasodilation) to release excess heat.
  • In order to keep blood pressure stable despite the dilation of the blood vessels, the heart increases its performance by up to 50%.
  • The heart rate increases to 120–150 beats per minute, similar to that experienced during light physical exertion (e.g. brisk walking)

Why does blood pressure only drop later?
Immediately after a sauna session, during the cooling and resting phase, blood pressure and heart rate drop significantly again and this is where the real effect unfolds:

  • Systolic blood pressure can drop from an average of 137 mmHg to 130 mmHg after a sauna session.
  • The diastolic value also decreases from 82 mmHg to about 75 mmHg.
  • Even 30 minutes after taking a sauna, blood pressure remains measurably lower than before.

This effect is partly due to fluid loss, but more importantly, it reflects a long-term adaptation of the vascular system. The endothelium, the inner lining of the blood vessels, responds to regular sauna use in a way similar to endurance training, becoming more elastic and functional. Sauna bathing also positively influences the regulation of stress hormones. Levels of cortisol and adrenaline decrease, which contributes to improved blood pressure control over time.

Good to know: Regular sauna use can prolong life

A long-term Finnish study shows that people who go to the sauna several times a week significantly reduce their risk of sudden cardiac death and coronary heart disease and statistically live longer. The overall risk of death and the likelihood of developing dementia were also noticeably reduced in the study. Saunas are good for you, and can do more than you may realise.
 

Stress, sleep and high blood pressure – why the sauna can be so valuable

When blood pressure is persistently elevated, there isn't always a physical cause. Stress often plays a role, whether at work, in everyday life, or due to persistent inner tension. Many people with high blood pressure report that they find it difficult to switch off and also lack restful sleep.

This is precisely where regular sauna bathing can help, not only physically, but also mentally. The soothing warmth relieves tension, calms the autonomic nervous system, and helps to relax the mind.

After a sauna session, stress hormone levels drop, muscles relax, and a natural feeling of tiredness sets in; the perfect conditions for a restful night. Those who sleep better recover faster. And in the long run, this also relieves the strain on the cardiovascular system.

If you live with high blood pressure, the sauna, when used correctly, can be far more than a place to relax. It can become an integral part of your personal health routine.

Multisensory environment ensures positive effects

A bonus for your wellbeing: The positive effects of a sauna session aren't solely due to the temperature. As researchers at Martin Luther University Halle-Wittenberg show, the combination of dim lighting, quiet music, and gentle scents can significantly deepen the relaxation experience. For people with high blood pressure, this tranquil, multisensory environment offers the opportunity to specifically reduce stress, without overtaxing the circulatory system. An environment that allows both body and mind to relax.

Gentle and effective – which sauna is suitable for high blood pressure

If you're not an experienced sauna user, the German Hypertension League recommends taking extra care when using a sauna with high blood pressure. Especially in the initial phase, moderate temperatures, a shorter stay, and as little circulatory strain as possible are essential. The decisive factor is not only the duration of the sauna session, but also which type of heat you choose.

  • The classic Finnish sauna, with temperatures up to 90°C, is intense and dry. It's more suitable for experienced sauna-goers with stable blood pressure and many people with hypertension find it too demanding.
  • The steam bath is significantly milder: At around 45 to 50°C and high humidity, it creates a gentle, humid climate that can be particularly pleasant for those with circulatory sensitivity. The heat feels soft, places less strain on the body, and yet still provides a soothing feeling of warmth and equally beneficial effects.
  • Infrared cabins offer an alternative form of heat treatment. The infrared radiation penetrates deep into the body. It promotes blood circulation, activates the metabolism, and relieves muscle tension. At the same time, it can significantly relieve circulatory stress, which many people with high blood pressure find very beneficial.
  • The SANARIUM® –, known as a bio sauna, from KLAFS offers a particularly versatile and circulatory-friendly heat treatment . Unlike the classic Finnish sauna, it operates at moderate temperatures between 40 and 75°C and a relative humidity of 40% to 55%, a climate that is perceived as pleasantly warm and significantly less stressful for the circulatory system. Different programmes can be set as needed, such as a tropically humid bath or an invigorating aroma bath.

A long-term study conducted at the Charité Berlin, led by Dr. Hans-Joachim Winterfeld, demonstrates that the SANARIUM® is not only relaxing but also medically effective. Over a period of two years, patients with high blood pressure regularly participated in circulatory-friendly SANARIUM® sessions twice a week, each session lasting eight to ten minutes. The result? More than a third of the participants experienced normalised blood pressure levels, without medication. Resting heart rate was also reduced. This is convincing evidence of how the gentle warmth can contribute sustainably to stabilising the cardiovascular system in patients with high blood pressure.

By the way, even those who tend to have low blood pressure and therefore frequently suffer from dizziness or fatigue can benefit from the gentle climate in the SANARIUM® . Doctors recommend this mild form of sauna bathing because it improves peripheral microcirculation: the blood flow to the small vessels in the arms and legs. After just a few weeks, circulation can stabilise. A wonderful remedy that not only offers soothing relaxation but also works wonders for your health.

Sauna safely with high blood pressure

With a little mindfulness, sauna use can be safe and beneficial, even if you have high blood pressure. These recommendations will help you take care of your circulation, without sacrificing the relaxing effects of the heat:

  • Choose moderate temperatures: Start with milder settings and only increase the intensity when you feel comfortable.
  • Limit the duration: Two short sauna sessions of eight to ten minutes each are often easier to tolerate than one longer stay.
  • Drink enough: After a sauna session, still water or isotonic drinks help to compensate for fluid loss.
  • Plan rest breaks: Your circulation benefits from conscious recovery phases between courses.
  • Consider medications: If you are taking blood pressure medications, talk to your doctor beforehand about possible complications.

And especially important: Opt for gentle cooling. It's an essential part of the process. To avoid high blood pressure after a sauna, the cooling down shouldn't be too abrupt. Cold plunge pools are too intense for many people with high blood pressure. Lukewarm showers or short periods in the fresh air are more suitable, gently bringing the body back into balance. 

It's precisely this interplay between heat and coolness that makes sauna bathing so effective. The heat dilates the blood vessels, while the subsequent cold causes them to contract again causing a gentle vascular workout that promotes elasticity and strengthens the cardiovascular system. This is how the sauna unfolds its holistic effect. Relaxing, stabilising, and regenerating all at once.

Going to the sauna with high blood pressure – what to consider regarding medication and individual risks

Many people with stable high blood pressure can enjoy the soothing warmth of a sauna without concern. The key is to listen to your body and avoid overexerting yourself. However, special care should be taken, especially if you are taking medication. Certain antihypertensive medications, such as beta-blockers, affect heart rate and can alter natural circulatory regulation during and after a sauna session.

This doesn't mean you have to avoid saunas, but it does mean it's a good idea to consult with your doctor. This way, potential risks can be assessed and recommendations regarding temperature, duration, and cooling down can be tailored specifically to your individual situation. And even if you're unsure, it's best to ask again. When used correctly, sauna bathing can not only be relaxing but also a beneficial companion on the path to greater balance and wellbeing, especially if your circulatory system needs special attention.

Important: If you have acutely uncontrolled or very high blood pressure, severe cardiovascular disease, or an infection, you should generally avoid using a sauna. Warning signs such as dizziness, rapid heartbeat, or malaise are also clear indicators. Give your body some rest - it's telling you what it needs.

Sauna and lowering high blood pressure – the effect comes with routine

Regular sauna bathing challenges the cardiovascular system, albeit in a gentle, steady way. Studies show that the physiological benefits of the sauna are comparable to those of light endurance training. The blood vessels are activated, and the circulation is stimulated, all without muscular strain.

For people with high blood pressure who are physically limited or less active, sauna bathing can therefore be a valuable addition to their daily routine. It's important to note that the positive effects, which are similar to that of exercise, don't occur immediately, but more so with regular use. Long-term observations show that in patients with cardiovascular disease, a significant reduction in blood pressure remained detectable, even after three years. It takes some patience and consistency for the body to adapt and benefit sustainably. Take your time. And let the heat work for you.

Finding balance with high blood pressure - how sauna bathing can gently support your health

High blood pressure can't simply be wished away but it can be consciously managed. Regular sauna use can help your body naturally relax and stabilise your blood pressure. It doesn't require a complex programme or major changes. Often, it's enough to simply give yourself regular breaks in an environment that promotes relaxation without adding stress.

Whether to complement therapy or as a conscious routine for increased wellbeing, going to the sauna can have more of an impact on high blood pressure than you might think. Gentle warmth, mindful application is how wellness works with impact.

FAQs about saunas for high blood pressure

Yes – if your blood pressure is well controlled and you don't have any acute symptoms, there's generally nothing medically wrong with taking a sauna. It's important to keep the temperature moderate, avoid overexerting yourself, and consult your doctor if in doubt.

If your blood pressure is well regulated and you feel comfortable during a sauna session, there's generally nothing wrong with staying in the sauna for 8 to 10 minutes per session. Two to three such sessions are well tolerated, with sufficient rest breaks in between. However, these times are only a guideline and your individual sensitivity to heat and your personal wellbeing are always crucial. If you feel unwell, you should stop the sauna at any time and give your body a rest. It's important to listen to your body, avoid striving for record heat levels, and seek medical advice beforehand if you're unsure. Also, make sure you cool down gently and drink plenty of fluids.

For high blood pressure, a gentle, well-tolerated heat experience is essential. Traditional high-temperature saunas aren't off limits, but for many people, milder versions are significantly more pleasant and gentler on the circulation. For example, a steam bath, with temperatures around 45°C and high humidity, offers a particularly gentle alternative that supports relaxation without placing undue strain on the cardiovascular system.

The SANARIUM® is particularly recommended as it combines moderate temperatures with increased humidity and allows for a customisable sauna experience through selectable climate zones. Studies show that regular SANARIUM® sessions can even lead to a lasting improvement in high blood pressure levels, without medication. The important thing is that you feel comfortable and don't overexert yourself. Listen to your body and choose the type of sauna that suits you best.

Yes, several scientific studies show this. With regular use, about two sauna visits per week, blood pressure can be lowered in the long term. The heat relaxes the blood vessels, regulates the heart rate, and supports the circulation. Important: The effects don't occur immediately but develop over weeks, similar to endurance training.
