Is it possible to go to a sauna if you have high or low blood pressure?

Relaxing in a sauna is not only enjoyable but also has a positive impact on well-being. Sauna treatments have a comprehensive effect on the body, including the cardiovascular system and blood pressure.

People with hypertension or hypotension should know how sauna treatments affect their condition and whether they can safely use a sauna. For those with hypertension, such a sauna can trigger a rise in blood pressure, which can lead to a hypertensive crisis, stroke, or heart attack. For those with hypotension, the sudden dilation of blood vessels due to heat can cause an even greater drop in blood pressure, even leading to fainting. Therefore, people with blood pressure regulation issues should approach the sauna with caution.

In this article, we will examine the factors that determine changes in blood pressure and provide recommendations for safe sauna use.

How does a sauna affect blood pressure?

Exposure to excessively warm and humid air triggers a number of physiological changes, including changes in the cardiovascular system and blood pressure.

When entering a steam room, a short-term increase in hypertension (high blood pressure) may be observed. This is due to the body’s response to high temperatures, increasing heat loss by dilating peripheral blood vessels, which leads to an increase in blood volume in the vascular bed and, consequently, an increase in blood pressure.

After the initial increase, blood pressure begins to gradually decrease. This occurs due to vasodilation and increased blood flow in the skin and subcutaneous fat. Vasodilation reduces peripheral resistance to blood flow, easing the work of the heart and contributing to a decrease in blood pressure.

After leaving the steam room, gradually cooling down, and resting, blood pressure gradually returns to its baseline level. In healthy individuals, this process occurs within 15-20 minutes.

It is worth noting that regular use of the steam room and sauna has a long-term positive effect on blood pressure. A study conducted in Finland found that people who used a sauna 4-7 times a week had a 46% lower risk of developing hypertension.

Thus, saunas can have both short-term and long-term effects on blood pressure. People with hypertension and hypotension should exercise caution when visiting a sauna and consult a physician or cardiologist beforehand.

Blood pressure changes during sauna use

People with hypertension have a more pronounced reaction to sauna treatments. A study showed that after sauna use, patients with hypertension experienced an average decrease in systolic blood pressure (the upper number) by 7 mmHg, and diastolic blood pressure (the lower number) by 5 mmHg. However, people with underlying cardiovascular conditions or after contrast treatments (ice water dousing, cold plunges, etc.) may experience a rapid increase in blood pressure. This increases the risk of hypertensive crisis, myocardial infarction, or stroke.

In people with hypotension, sauna treatments can cause an even greater drop in blood pressure, which can lead to dizziness, weakness, and even loss of consciousness. Therefore, people with hypotension should exercise caution when visiting a sauna, limit their time spent there, and closely monitor their well-being.

In healthy people, the body usually quickly adapts to changes in temperature and humidity, allowing it to maintain stable blood pressure. In people predisposed to hypertension or other medical conditions, this adaptation may be impaired.

During a steam bath, the body loses a significant amount of fluid through sweating. This can cause temporary hypotension (low blood pressure), especially if the lost fluid is not replaced. Dehydration can also cause dizziness and weakness.

A sauna can be beneficial for your health if you monitor your well-being and take into account your individual body’s characteristics. The right approach will allow you to enjoy all the benefits of sauna treatments without any health risks.

How does steam affect blood vessels?

Steam has a powerful effect on blood vessels, promoting their dilation, improving blood flow, and lowering blood pressure.

Vasodilation. When a person is in a steam room, the high temperature stimulates the skin’s thermoreceptors, which send signals to the hypothalamus, the part of the brain responsible for thermoregulation. In response, the hypothalamus stimulates the dilation of peripheral blood vessels, especially capillaries and arterioles, to increase blood flow to the skin and enhance heat transfer.

Increased Blood Flow. Vasodilation leads to increased blood flow in the skin and subcutaneous fat. This improves the delivery of oxygen and nutrients to cells and accelerates the removal of metabolic waste and toxins.

Vascular training. Under the influence of high temperature, blood vessels dilate, and upon leaving the steam room, they constrict. This vascular exercise helps maintain their elasticity and improves cardiovascular function.

Sauna for High Blood Pressure

A sauna is a popular way to relax and improve your health, but people with hypertension should exercise caution. The microclimate of a steam room can further increase blood pressure, which can lead to complications. Following certain rules will help make sauna treatments a beneficial and relaxing experience.

1. Consult a doctor. Before visiting a sauna, consult a doctor. They will assess your health and give you personalized recommendations.
2. Monitor your blood pressure. Measure your blood pressure before visiting a sauna. If it is too high, it is best to postpone sauna treatments. During periods of hypertension exacerbation, this type of relaxation is contraindicated.
3. Choose a time for relaxation. For hypertension, it is best to visit a sauna in the morning, when stress levels are lower. Try to avoid evening visits, as they can negatively impact the quality of sleep.
4. Limit your time. People with hypertension are advised to limit their time in the sauna. Start with short sessions (5-7 minutes) and gradually increase the duration, carefully monitoring any negative changes in your condition.
5. Rest between sessions. Take breaks between steam room visits to rest and recover. But don’t overcool! Put on a towel or robe in the relaxation room.
6. Temperature and Humidity. When visiting a sauna if you have hypertension, choose a moderate temperature in the sauna (no higher than 70-80°C) and medium humidity. Excessive stress on the body can cause a spike in blood pressure and a deterioration in well-being.
7. Drink enough fluids. Drink plenty of fluids (preferably warm) to avoid dehydration. Herbal tea helps lower blood pressure.
8. Avoid sudden temperature changes. Choose sauna programs that avoid strong and profound contrasts. After warming up and steaming, do not dive into a cold pool or immerse yourself in an icy plunge pool. Such procedures can cause a sudden increase in blood pressure, so cool down gradually.
9. Listen to yourself. If you experience weakness, blurred vision, nausea, rapid heartbeat, or shortness of breath, leave the steam room immediately and rest in a place with ample fresh air.

Remember that a sauna puts stress on the cardiovascular system. Visiting a sauna with high blood pressure is possible, but you should be especially careful and cautious during the procedures. Regular blood pressure monitoring, a healthy lifestyle, and following your doctor’s recommendations will help reduce risks and ensure a safe sauna experience.

Rules for visiting a banya if you have low blood pressure

People with hypotension, like those with high blood pressure, should exercise caution when visiting a steam room. The sudden dilation of blood vessels due to heat can cause an even greater drop in blood pressure, which can lead to fainting and dizziness. Certain rules must be followed to avoid any unpleasant consequences. Here are some recommendations:

1. Consult a doctor. Before visiting a banya, consult a doctor to ensure that your visit will not lead to any negative consequences. Your doctor will assess your health and provide recommendations for a safe experience.
2. Choose a time to relax. It is best to visit a banya in the morning or afternoon, when your energy levels are highest. Avoid evening visits, as fatigue can worsen symptoms of hypotension.
3. Limit your time in the steam room. Avoid staying in the steam room for too long. Start with short sessions (5-10 minutes) and gradually increase the time as your health allows. Take 15-20 minute breaks between sessions to allow your body time to recover and adapt to the temperature changes.
4. Use contrast treatments with caution. If you want to try contrast treatments, do so carefully and monitor your condition closely. Sudden temperature changes can cause dizziness and loss of consciousness in those with low blood pressure.
5. Maintain your fluid balance. Avoid dehydration. Drink warm liquids (water, herbal tea, or fruit juice) before and after your sauna session, between visits to the steam room.
6. Rest between sessions. Between visits to the steam room, rest in a cool room or outdoors. This will help stabilize your blood pressure and improve your well-being.
7. Avoid visiting the sauna on an empty stomach. A light meal rich in carbohydrates and proteins will help maintain your energy levels.
8. Listen to your body. If you experience dizziness, weakness, or other unpleasant symptoms, leave the steam room immediately and rest in a cool place.
