How Does an Outdoor Sauna Work?

25 minutes read

An outdoor sauna works by using a heat source to warm up a small, insulated room, typically made of wood. The heat can be generated by various methods such as a wood-burning stove, electric heater, or gas heater. The interior is often designed with benches for sitting or reclining, allowing individuals to relax in the high heat environment. The sauna's temperature is usually maintained between 150 to 195 degrees Fahrenheit (65 to 90 degrees Celsius) with low humidity. Water can be poured over heated rocks to create steam, which temporarily increases humidity and enhances the sensation of heat. The overall effect of an outdoor sauna is to promote relaxation, improve circulation, and encourage sweating, which can aid in detoxification and muscle recovery. Proper ventilation is crucial to ensure the sauna remains safe and comfortable, and a cold shower or plunge into a cold pool afterwards is often recommended to cool down and refresh the body.

How to maintain an outdoor sauna?

Maintaining an outdoor sauna is essential to ensure its longevity, safety, and optimal performance. Here are some guidelines to help you keep your outdoor sauna in great condition:

  1. Regular Cleaning: Interior: Wipe down the bench surfaces and walls with a mild detergent or a solution of vinegar and water. Avoid harsh chemicals that can damage the wood. Exterior: Use a gentle soap and water to clean the exterior surfaces. If the sauna is made of wood, you might occasionally want to apply a sealant or stain (following the manufacturer's recommendations) to protect it from the elements.
  2. Inspection: Regularly check for signs of wear and tear, such as cracked wood or damaged elements. Respond to any issues promptly to prevent further deterioration. Inspect the heater periodically for any signs of rust or malfunction. Make sure the stones are in good condition and replace them if they start to crack or degrade.
  3. Ventilation: Ensure that vents and any air circulation systems are clean and functioning properly. Proper ventilation is crucial for maintaining the sauna's air quality and preventing moisture build-up.
  4. Wood Maintenance: Avoid painting or varnishing the interior wood surfaces as this can prevent the wood from breathing and can emit harmful fumes when heated. Sand any rough spots on benches or other areas to maintain a smooth, comfortable surface.
  5. Electrical and Heating System: If your sauna has electrical components, ensure that they are working properly and are regularly checked by a qualified electrician. Clear the heater of dust and debris, and make sure that the stones are evenly distributed and not too tightly packed.
  6. Protecting from the Elements: Consider using a weather-resistant cover or roofing to protect the sauna from rain, snow, and excessive sunlight when not in use. Ensure that the sauna’s foundation provides adequate drainage to prevent water damage.
  7. Natural Treatments: You can use natural oils such as linseed oil on the exterior wood to help maintain its appearance and protect it from weather conditions. Be cautious on using oils on the interior, as some can become sticky or emit smells when heated.
  8. Routine Check-Ups: Have a regular schedule for checking the sauna’s condition and carrying out necessary maintenance tasks. Routine checks will help in catching any issues early on.
  9. Usage Practices: Encourage users to sit on towels to reduce sweat absorption into the wood. This helps keep the sauna cleaner and makes maintaining it easier. Make sure to air out the sauna after each use by leaving the door open to allow moisture to escape.


By following these maintenance practices, you can ensure that your outdoor sauna remains a comfortable and enjoyable retreat for years to come.


How does long-term sauna use affect longevity?

Long-term sauna use has been associated with several potential health benefits that may contribute to increased longevity. These benefits include improved cardiovascular health, reduced risk of certain diseases, enhanced physical performance, and improved mental health. Here are some of the ways long-term sauna use could impact longevity:

  1. Cardiovascular Health: Regular sauna use has been shown to improve circulation and reduce blood pressure, both of which are important for heart health. Studies, particularly those from Finland, suggest that frequent sauna use may lower the risk of cardiovascular events like heart attacks and strokes.
  2. Reduced Risk of Disease: Sauna bathing has been associated with a reduced risk of neurodegenerative diseases, such as Alzheimer's and dementia. Some research also indicates a correlation between regular sauna use and reduced mortality from certain diseases, including heart disease.
  3. Detoxification and Immunity: The high temperatures in a sauna can aid in detoxification by promoting sweating, which is one way the body expels toxins. Some research suggests that saunas may help strengthen the immune system, potentially leading to fewer illnesses.
  4. Improved Mental Health: Regular sauna use may help reduce stress and improve mental well-being, potentially due to the relaxation and increased endorphin release associated with heat exposure. This can translate to a lower risk of chronic stress-related health issues.
  5. Physical Performance and Recovery: Saunas may help in muscle relaxation and recovery, reducing muscle soreness and improving joint movement. This can be especially beneficial for athletes or those who engage in regular physical activity.
  6. Inflammation and Pain Relief: The heat from saunas may help reduce systemic inflammation and provide relief from certain types of chronic pain, contributing to improved overall health and quality of life.


It's important to note that while there are many potential benefits, sauna use is not suitable for everyone. Individuals with certain health conditions, such as low blood pressure or cardiovascular instability, should consult with a healthcare professional before using a sauna. Additionally, moderation and safe practices should always be observed to avoid dehydration and overheating. Overall, while more research is needed to fully understand all the effects, sauna use appears to offer promising benefits for longevity when used appropriately.


What is a smoke sauna?

A smoke sauna, often referred to as a "savusauna" in Finland, is a traditional type of sauna that is characterized by its unique heating method. Unlike modern saunas that use an electric or continuously burning wood stove with a chimney, a smoke sauna is heated without a chimney. Here's how it works:

  1. Heating Method: Large stones are placed on top of a wood-burning stove inside the sauna. The wood is burned directly in the stove, and the smoke fills the sauna room as the fire heats the stones over several hours.
  2. Ventilation Process: Once the stones are sufficiently heated, the fire is extinguished, and the sauna is ventilated by opening doors and windows to allow the smoke to escape. This process can take some time to ensure that there are no lingering fumes.
  3. Sauna Experience: After the smoke has cleared, the residual heat from the stones provides the sauna's warmth. Water can be thrown onto the stones to produce löyly, the steam that enhances the sauna experience.
  4. Characteristics: Smoke saunas are known for their gentle heat and soft steam. Due to the wood smoke, these saunas often have a distinct, pleasant aroma and a dark, soot-lined interior, lending a rustic and authentic feel.


Smoke saunas are highly revered in Finnish culture and are considered a more traditional and authentic form of the sauna experience. They are often associated with rural or countryside settings and can be a rarity due to their labor-intensive setup and maintenance.


How does heat in an outdoor sauna improve health?

Using a sauna, particularly an outdoor one, can offer several health benefits due to the heat it provides. Here's how it can improve health:

  1. Improved Circulation: The heat from a sauna causes blood vessels to dilate, increasing blood circulation. Enhanced circulation can help with muscle regeneration, joint mobility, and overall cardiovascular health.
  2. Detoxification: Sweating in a sauna helps the body expel toxins through the skin. While the liver and kidneys primarily handle detoxification, sweating can complement these organs by eliminating salt, alcohol, nicotine, and heavy metals.
  3. Stress Reduction and Relaxation: The warmth of a sauna can help increase the levels of endorphins, which are the body's natural stress-relievers. This can lead to reduced stress and improved mood.
  4. Muscle Relaxation and Pain Relief: Heat from a sauna can soothe sore muscles, alleviate joint pain, and improve flexibility. This makes it a useful therapy for individuals with arthritis or muscle injuries.
  5. Improved Immune Function: Regular sauna use can stimulate the production of white blood cells, which play a key role in fighting infection. This can lead to a stronger immune system overall.
  6. Skin Health: Heat and sweating can open pores, helping to release dead skin cells and contributing to cleaner, softer skin. The increased blood flow to the skin can also promote healing.
  7. Respiratory Benefits: The heat and humidity of a sauna may help open airways and alleviate congestion, providing relief for individuals with respiratory issues such as bronchitis or asthma.
  8. Metabolic Rate Increase: The heart rate increases as your body works to cool itself, which can temporarily boost your metabolism, similar to light exercise.
  9. Cardiovascular Health: Regular sauna sessions have been linked to a reduced risk of death from cardiovascular events and may help regulate blood pressure.
  10. Improved Sleep: The relaxation experienced post-sauna can lead to deeper, more restful sleep, as sauna use can trigger a natural release of endorphins, followed by a decrease in body temperature.


It's important to stay hydrated and listen to your body while using a sauna, as excessive heat can pose risks, especially for individuals with certain medical conditions or those who are pregnant. Always consult with a healthcare professional before starting a sauna routine to ensure it's safe for you.
