Sauna Health Benefits: Why Sauna Use is Becoming Increasingly Popular

In recent years, the popularity of saunas has surged, especially among those looking to improve their health and wellbeing. From gym-goers to those seeking relaxation, saunas are widely regarded as an excellent addition to any health routine. But why has this centuries-old practice, which originated in colder climates, become so relevant today?

The Growing Popularity of Saunas: A Path to Better Health and Wellness

Saunas have long been a part of various cultures’ wellness routines, but in recent years, they’ve gained significant traction as people look for holistic ways to enhance their physical and mental well-being. From detoxification to cardiovascular health, traditional saunas offer a range of proven benefits, with research increasingly highlighting their role in modern health strategies.

The tradition of sauna use dates back thousands of years, particularly in Finland, where saunas are deeply embedded in daily life. An estimated 65-70% of Finnish households have a sauna, reflecting how ingrained this practice is in their culture . Saunas are used not only for relaxation but also as part of regular health routines, with many Finns using saunas several times a week. While there is no definitive data linking sauna use directly to the overall health of the Finnish population, Finland does have one of the lowest rates of cardiovascular disease in Europe , and many researchers hypothesise that regular sauna use may play a role in this.

General Overview of Health Benefits

Sauna use has become a focal point for those looking to support their overall health. From professional athletes to wellness influencers, many are recognising the numerous physical and mental health benefits associated with regular sauna sessions. Advocates like Dr. Andrew Huberman, a neuroscientist and host of the popular podcast Huberman Lab, highlight how sauna use can improve everything from cardiovascular health to cognitive function .

Saunas offer a unique combination of benefits, from enhancing circulation to aiding detoxification. The heat exposure increases heart rate, mimicking the effects of moderate exercise. Regular sauna use has been linked to improved heart health, lower stress levels, and faster recovery from physical stress. This has made saunas a staple in both fitness and wellness routines globally.

Specific Health Benefits

1. Cardiovascular Health

One of the most well-documented benefits of sauna use is its positive impact on cardiovascular health. Studies from the University of Eastern Finland found that people who use saunas 4-7 times a week have a significantly lower risk of cardiovascular diseases . This is primarily due to the way saunas promote circulation by dilating blood vessels, reducing blood pressure, and improving heart function. Over time, regular sauna use can contribute to overall heart health and reduce the risk of heart attacks and strokes.

2. Mental Wellbeing

Saunas also play a critical role in improving mental health. The heat exposure triggers the release of endorphins, which act as natural mood lifters, and helps reduce cortisol levels, which are linked to stress. Dr. Andrew Huberman has frequently discussed the mental benefits of sauna use, noting that regular sauna sessions can help reduce symptoms of anxiety and depression by regulating neurotransmitters in the brain . This makes saunas an excellent addition to any routine for those seeking both mental clarity and relaxation.

3. Pain Relief for Chronic Conditions

Saunas have been shown to offer relief for people with chronic pain conditions such as arthritis and fibromyalgia. A 2019 study in the Journal of Clinical Rheumatology found that individuals with rheumatoid arthritis experienced reduced joint stiffness and improved mobility after regular sauna sessions . Similarly, people suffering from fibromyalgia reported significant reductions in muscle pain and overall discomfort. Saunas are believed to ease pain by improving blood flow and reducing inflammation.

4. Detoxification

One of the most widely recognised benefits of sauna use is detoxification. Sweating in a sauna helps flush out toxins such as heavy metals, which accumulate in the body over time. A study published in the Archives of Environmental & Occupational Health showed that regular sauna sessions aid in eliminating heavy metals like lead, mercury, and cadmium . Detoxifying the body in this way helps reduce the toxic load, supporting the immune system and preventing long-term health issues.

5. Muscle Recovery

For athletes and fitness enthusiasts, saunas offer a natural method to promote faster muscle recovery. The increased blood flow helps flush out lactic acid and reduces muscle soreness, allowing for quicker recovery post-exercise. By aiding in recovery, saunas can enhance athletic performance and help prevent overuse injuries.

New Research and Developments

Recent research has begun to explore even more potential benefits of regular sauna use. Several studies are investigating how saunas might support neurological health and reduce the risk of diseases like Alzheimer’s and dementia. Improved circulation to the brain and the production of brain-derived neurotrophic factor (BDNF) are believed to contribute to cognitive health. Preliminary research suggests that regular sauna sessions could help protect against neurodegenerative diseases by promoting brain function and resilience.

Emerging research is also exploring the potential benefits of sauna use for sexual health, particularly in men. Improved blood flow, which is a core benefit of sauna use, is linked to enhanced erectile function. Although the research is in its early stages, these findings suggest saunas may have a positive impact on sexual health.

Influencer Insights

Dr. Andrew Huberman

Dr. Andrew Huberman, a neuroscientist at Stanford University and host of the Huberman Lab podcast, is a well-known advocate of sauna use. With a PhD in neuroscience, his work has been featured in major publications such as The New York Times and Men’s Health. Dr. Huberman’s sauna protocol involves sessions 4-7 times a week for around 30 minutes at temperatures between 80-100°C. He emphasises the mental and physical benefits, including improved cardiovascular health and cognitive function .

Dr. Rhonda Patrick

Dr. Rhonda Patrick, a biochemist and researcher, has also been pivotal in highlighting the health benefits of sauna use. With a PhD in biomedical science, she’s appeared in numerous publications, including Forbes and Men’s Journal. Dr. Patrick has referenced Finnish studies that show regular sauna use may reduce all-cause mortality by up to 40%, attributing these benefits to the impact saunas have on cardiovascular health .

Tim Ferriss

Tim Ferriss, best known for his book The 4-Hour Body, has publicly praised sauna use as a tool for both physical and mental wellbeing. Ferriss calls saunas a “secret weapon” for staying fit and mentally sharp in today’s fast-paced world .

Traditional vs. Infrared Saunas

While both traditional and infrared saunas offer health benefits, research tends to favour traditional saunas, particularly in cultures like Finland. Traditional saunas heat the body through the surrounding air, offering a more intense and complete heating experience compared to infrared saunas, which rely on infrared panels to heat the body directly. Many studies, including those focusing on the Finnish population, show that traditional saunas offer superior cardiovascular and detoxification benefits .

Cold Therapy Integration

There is increasing evidence that alternating between hot saunas and cold therapy, such as ice baths, may enhance overall health benefits. The practice of moving between extreme heat and cold helps improve circulation, reduce inflammation, and support the immune system. A study from the European Journal of Applied Physiology found that cold exposure after a sauna session can increase the body’s ability to repair damaged tissue and may enhance recovery from exercise-induced stress . This combination of heat and cold is becoming a popular practice in the wellness space, with more research underway to understand its full potential.
