If you have ever considered stepping into a sauna, you might be surprised to learn about the extensive list of benefits that come along with it. From pain relief to improved cardiovascular health, saunas offer a wide range of advantages for both your body and mind. In this article, we will explore these benefits and shed light on why saunas have become a beloved practice for many.
What is a Sauna?
A sauna is a small room or enclosure that is heated to high temperatures, typically using dry heat or steam. Saunas are often made of wood and can be found in different styles, including traditional saunas, infrared saunas, and even portable saunas.
Types of Saunas
There are various types of saunas available that offer different experiences and benefits. Let’s explore the most common types:
1. Wood-Burning Saunas: These saunas are heated by burning wood, typically logs or firewood. They create a traditional and rustic sauna experience, with temperatures ranging from 150°F to 190°F (65°C to 88°C). The heat is dry, and the humidity levels are relatively low. Wood-burning saunas are favoured by enthusiasts who enjoy the natural ambiance and aroma.
2. Electrically Heated Saunas: Electrically heated saunas use heating elements to produce heat. They are easier to control and maintain steady temperatures, typically ranging from 120°F to 150°F (49°C to 66°C). The heat is dry, and the humidity levels are moderate. Electric saunas are popular for their convenience and ease of use.
3. Steam Rooms: Steam rooms, often found in gyms or wellness centres, use a steam generator to produce high humidity and lower temperatures ranging from 100°F to 120°F (38°C to 49°C). The moist heat envelops the body, creating a soothing and relaxing experience. Steam rooms are known for their ability to open up pores and promote detoxification.
4. Infrared Saunas: Infrared saunas use infrared heaters to emit radiant heat, which is directly absorbed by the body without significantly heating the surrounding air. Temperatures in infrared saunas typically range from 120°F to 150°F (49°C to 66°C). The heat is dry, and the humidity levels are low. Infrared saunas are praised for their ability to penetrate deeper into the muscles, providing a focused therapeutic experience.
Each type of sauna offers unique benefits, and personal preference plays a significant role in determining which one suits your needs.
What are the Benefits of a Sauna?
Beyond the enjoyable experience of sitting in a sauna, there are numerous potential health benefits associated with regular sauna use. These benefits extend to both physical and mental well-being.
Easing Pain
Saunas are not only a place to relax and unwind, but they can also provide relief from pain and discomfort. By increasing circulation and reducing muscle soreness, sauna use can effectively ease pain and improve joint movement.
The heat in a sauna causes blood vessels to dilate, which in turn increases blood flow to muscles and other tissues. This increased circulation can help deliver oxygen and nutrients to the affected areas, promoting healing and reducing pain. Furthermore, saunas can aid in reducing muscle soreness by helping to relax tense muscles and reducing inflammation.
Individuals with chronic musculoskeletal diseases, such as rheumatoid arthritis and ankylosing spondylitis, can benefit greatly from sauna use. Research has shown that regular sauna sessions can improve symptoms such as pain, stiffness, and fatigue in these conditions. The heat from the sauna can help to alleviate joint pain and increase flexibility, making movement easier for individuals with these conditions.
For individuals experiencing lower back pain, saunas can be a potential solution for relief. By stimulating blood flow to the lower back, saunas can help reduce pain and improve mobility. It is recommended to conduct a trial session to determine if sauna use effectively alleviates symptoms. Every individual’s experience may vary, so it is important to listen to your body and consult with a healthcare professional if needed.
In short, incorporating sauna sessions into your wellness routine may help you find respite from pain and enjoy a better quality of life.
Reducing Stress Levels
Saunas not only provide physical health benefits but can also have a significant impact on reducing stress levels. The heat in a sauna promotes relaxation by easing tense muscles and calming the mind. This relaxation response helps alleviate stress and allows individuals to unwind and find a sense of tranquility.
Additionally, saunas improve circulation throughout the body, which can further contribute to stress reduction. The increased blood flow to muscles and tissues helps deliver oxygen and nutrients, enhancing overall well-being.
A prospective cohort study published in the Journal of Human Hypertension found that sauna bathing can lead to a decrease in cortisol, the hormone associated with stress, by 10 to 40 percent. This suggests that regular sauna sessions can have a direct impact on reducing stress levels.
By incorporating sauna sessions into your routine, you can create a regular practice that helps manage and reduce stress. Whether it’s a weekly or monthly habit, taking the time to relax in a sauna can provide a mental and emotional break, promoting a more balanced and stress-free lifestyle.
Improving Cardiovascular Health
Saunas offer several potential health benefits, especially when it comes to improving cardiovascular health. A notable study conducted in Finland over a 20-year period found a link between regular sauna use and a lower risk of cardiovascular disease and sudden cardiac death.
Sauna use has been shown to potentially reduce blood pressure, enhance heart function, and increase cardiorespiratory fitness. Spending time in a sauna can cause blood vessels to dilate, promoting better blood flow and reducing hypertension. This effect may also improve overall heart health by reducing the workload on the heart and increasing its efficiency.
Regular sauna use can also lead to an increase in cardiorespiratory fitness. This is because the elevated heart rate experienced in a sauna session mimics the benefits of moderate exercise. This can help improve endurance and strengthen the cardiovascular system.
It is important to note that while sauna use can be beneficial for heart health, it should not be seen as a substitute for regular exercise. Exercise has its own unique benefits for cardiovascular health, including improved heart function, weight management, and increased circulation.
Improving Skin Problems
Sauna use can also be advantageous for individuals with skin problems. Regular sauna sessions can help improve skin strength, promote better circulation, and more.
The dry heat in a sauna helps to open up pores and cleanse the skin, which can be beneficial for those dealing with skin conditions such as acne, eczema, or psoriasis. The heat helps to promote sweating, which can contribute to a clearer complexion.
Furthermore, saunas stimulate blood circulation, bringing oxygen-rich blood to the surface of the skin. This increased blood flow can contribute to a healthier and more robust appearance, helping to nourish the skin and promote a natural glow.
Additionally, sauna sessions can help enhance collagen production, which is crucial for maintaining youthful and supple skin. Collagen is responsible for skin elasticity and strength, and the heat from the sauna can stimulate its production, potentially reducing the appearance of fine lines and wrinkles.
It is important to note that individuals with specific skin conditions should consult with their healthcare provider before incorporating sauna use into their routine. However, for many individuals, regular sauna use can provide potential benefits for their skin health, contributing to a clearer, more radiant complexion.
Relieving Asthma Symptoms
Asthma is a chronic respiratory condition that affects millions of people worldwide. It is characterised by inflammation and constriction of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath. While there is no cure for asthma, various management strategies can help control symptoms and improve quality of life.
Sauna bathing has been found to offer potential benefits for individuals with asthma. The heat and humidity in a sauna can help open up the airways and promote relaxation, which may provide relief from asthma symptoms. The high temperature in the sauna helps to dilate the bronchial tubes, allowing for improved airflow and easier breathing. This can be particularly beneficial during an asthma attack or when experiencing respiratory congestion.
In addition to opening up the airways, sauna use can also help loosen phlegm and mucus, making it easier to clear the respiratory passages. This can alleviate coughing and improve lung function in individuals with asthma.
Furthermore, sauna bathing has been shown to reduce stress, which is a common trigger for asthma symptoms. The relaxing environment of a sauna, coupled with the release of endorphins and improved blood circulation, can help lower stress levels and potentially reduce the frequency and intensity of asthma attacks.
It is important to note that sauna use should be approached with caution and discussed with a healthcare professional, particularly for individuals with severe or poorly controlled asthma. The duration and frequency of sauna sessions should be tailored to individual needs and preferences.
Lowering the Risk of Alzheimer’s
Sauna bathing has also shown potential in promoting cognitive health and reducing the risk of Alzheimer’s disease. A study conducted on a group of Finnish adults found that frequent sauna bathing was linked to a reduced risk of dementia and Alzheimer’s disease over a 20-year follow-up period.
According to the study’s findings, participants who used saunas 4-7 times per week had a 66% lower risk of developing dementia and a 65% lower risk of Alzheimer’s compared to those who used saunas only once a week. These findings highlight the potential protective effects of regular sauna use on cognitive health.
One of the key reasons sauna bathing may be able to lower the risk of Alzheimer’s is that, by promoting blood flow, saunas help deliver essential nutrients and oxygen to the brain. This aids in clearing out toxic plaques called amyloid plaques, which are abnormal protein deposits that are a characteristic feature of Alzheimer’s disease.
Furthermore, sauna bathing has been found to promote the production and release of brain-derived neurotrophic factor (BDNF), a protein responsible for the growth and maintenance of neurons in the brain. Low levels of BDNF have been associated with an increased risk of cognitive decline and neurodegenerative diseases such as Alzheimer’s. By increasing BDNF levels, sauna use may help protect against the loss of brain cells and improve overall cognitive function.
In addition to these direct effects on the brain, sauna bathing also provides other health benefits that indirectly support Alzheimer’s prevention. Regular sauna sessions have been shown to reduce chronic inflammation, which is believed to play a significant role in the development of Alzheimer’s disease. By decreasing inflammation, saunas help protect against the damage and degeneration of brain cells.
Moreover, saunas have been found to promote relaxation and improve sleep quality, both of which are crucial for cognitive health. Adequate sleep is essential for the brain to process and consolidate memories. By facilitating better sleep, sauna bathing may help enhance memory and cognition, reducing the risk of Alzheimer’s disease.
However, it is important to note that the study mentioned above has its limitations. The research was conducted on a specific population in Finland, where sauna use is a common practice. Therefore, the results may not be generalisable to other populations. Additionally, the study did not establish a direct cause-and-effect relationship between sauna use and decreased risk of dementia but rather observed an association.
Given the preliminary nature of these findings, more research is needed to confirm the potential benefits of sauna use for reducing the risk of Alzheimer’s disease. Future studies should include diverse populations and explore the underlying mechanisms by which saunas may exert their protective effects on cognitive health.
It is also crucial to consider individual factors and consult with a healthcare professional before incorporating sauna use into one’s routine, especially for individuals with pre-existing medical conditions or concerns. While sauna bathing shows promise, it is always advisable to approach it with caution and prioritise personal safety and well-being.
Sauna Risks
Blood Pressure Risk
Saunas have long been recognised for their potential health benefits, but it’s important to understand that there are some risks associated with their use, particularly in relation to blood pressure. While sauna sessions can provide a relaxing and enjoyable experience, they can also cause changes in blood pressure that may be concerning for certain individuals.
One potential risk is that sauna use may cause a drop in blood pressure. This can be especially problematic for individuals with low blood pressure or those who have recently had a heart attack. The sudden decrease in blood pressure can lead to symptoms such as dizziness, lightheadedness, or even fainting.
It is crucial to consult with a doctor before using a sauna, especially for individuals with existing blood pressure issues. Healthcare professionals can assess an individual’s medical history, current health conditions, and medications to determine if sauna use is safe for them. They may recommend adjusting the duration or frequency of sauna sessions or advise against using saunas altogether.
Dehydration Risk
Sauna use can pose a risk of dehydration due to increased fluid loss through sweating. It is important to be aware of this potential risk and take steps to avoid dehydration during and after sauna sessions.
Sweating is a natural response to the dry heat in saunas, which can cause a significant amount of fluid loss from the body. Signs of dehydration include increased thirst, dry mouth, fatigue, dizziness, and dark-coloured urine. To mitigate these risks, it is crucial to ensure proper hydration before and after using a sauna.
Drinking water before a sauna session helps to increase body fluid levels, while post-sauna hydration replenishes the fluids lost through sweating. Additionally, avoiding alcohol and caffeine, both of which can contribute to dehydration, is recommended.
Sauna Precautions
When using a sauna, it’s important to take precautions to ensure a safe and enjoyable experience. Here are some key steps to consider:
1. Avoid alcohol: Alcohol can increase the risk of dehydration and lower blood pressure, which can be dangerous when combined with the heat of a sauna. It’s best to avoid alcohol before and during sauna use.
2. Limit sauna time: To prevent overheating and dehydration, it is recommended to limit sauna sessions to around 20 minutes. Remember, it’s always better to start with shorter sessions and gradually increase the time as your body becomes more accustomed to the heat.
3. Hydrate properly: Stay hydrated before and after using a sauna. Drink plenty of water before entering the sauna to increase your body fluid levels. Rehydrate afterwards to replenish the fluids lost through sweating.
4. Avoid sauna use when ill: If you’re feeling unwell, it’s best to avoid using a sauna. Illness can affect your body’s ability to regulate temperature, increasing the risk of overheating.
5. Supervise children: Ensure that children using a sauna are supervised at all times. Their bodies may be more sensitive to heat, and they may not be able to recognise signs of discomfort or the need for hydration.
Sauna Myths
False: Sweating Removes Toxins
There is a common misconception that sweating removes toxins from the body. However, scientific evidence suggests otherwise. Sweating is the body’s natural response to regulate body temperature and cool down, but it is not a primary method of detoxification.
Toxins are primarily eliminated through the kidneys, liver, and intestines. These organs play a crucial role in breaking down and eliminating harmful substances from the body. While saunas can induce sweating, they do not significantly contribute to toxin elimination.
A study published in the Journal of Environmental and Public Health examined the effects of sauna bathing on toxin elimination. The results showed that while there were small amounts of certain heavy metals and other impurities present in sweat, the levels were much lower than what is excreted through urine and faeces.
Therefore, while sweating in a sauna can provide temporary relief and promote relaxation, it should not be seen as a reliable method of detoxification. It is essential to focus on supporting the natural detoxification processes of the liver, kidneys, and intestines by maintaining a healthy lifestyle, staying hydrated, and consuming a balanced diet.
False: Sauna Use Aids Weight Loss
There is a common belief that sauna use can aid in weight loss. However, it is important to separate fact from fiction when it comes to the effects of saunas on weight loss.
One common misconception is that sweating in a sauna leads to long-term weight loss. While it is true that you may experience temporary weight loss due to the loss of water through sweating, this weight loss is not sustainable. As soon as you rehydrate, the pounds lost will be regained.
It is also important to note that sweating in a sauna does not directly burn fat or boost your metabolism. While sauna sessions may raise your heart rate and increase blood circulation, they do not lead to significant fat loss.
For sustainable weight loss, it is crucial to focus on a healthy and balanced diet, regular physical exercise, and overall lifestyle changes. These factors, along with a caloric deficit, contribute to long-term weight loss.

Far-infrared saunas: do they work?
Far-infrared saunas have gained popularity in recent years due to their potential benefits for individuals with mobility problems and health issues that make it difficult for them to tolerate high temperatures. These saunas use far-infrared radiant heat to penetrate the body, providing a gentle and comfortable heat that is easier to withstand compared to traditional saunas.
One potential benefit of far-infrared sauna use is the improvement in high blood pressure. Some studies have shown that regular sessions in a far-infrared sauna can help lower blood pressure levels. Additionally, individuals with congestive heart failure, a condition where the heart is unable to pump enough blood to meet the body’s needs, may experience improved cardiovascular function and exercise tolerance with the use of far-infrared saunas.
Furthermore, far-infrared saunas have shown promise in reducing oxidative stress, a process linked to the development of chronic diseases. They may also provide relief from chronic pain and chronic fatigue syndrome. Though these benefits have been observed in some studies, it’s important to note that the evidence is limited and further research is needed to fully understand the effectiveness of far-infrared saunas.
