A comprehensive comparison of traditional Finnish saunas and infrared saunas, including benefits, differences, and which type suits your needs.
When choosing a sauna, you'll likely encounter two main types: traditional (Finnish) saunas and infrared saunas. Both offer significant health benefits, but they work differently and provide distinct experiences. This guide will help you understand the differences and choose the right type for your needs.
Traditional saunas, also known as Finnish saunas, heat the air around you using a stove (either wood-burning, electric, or gas). Rocks are heated on top of the stove, and water can be poured on them to create steam (löyly), increasing humidity.
Key characteristics of traditional saunas:
Air temperature: 70-100°C (158-212°F)
Humidity: Variable, 10-60% depending on water usage
Heating method: Convection (heated air)
Session length: Typically 15-20 minutes per round
Traditional experience with cultural roots
Infrared saunas use infrared light waves to directly heat your body rather than heating the air around you. The infrared spectrum is divided into near, mid, and far infrared, with most saunas using far infrared technology.
Key characteristics of infrared saunas:
Air temperature: 45-65°C (113-149°F)
Humidity: Low, typically dry heat
Heating method: Radiant heat directly to the body
Session length: Typically 30-45 minutes
Modern technology, less traditional feel
Traditional saunas provide intense heat through convection
Both types of sauna provide cardiovascular benefits, though the mechanisms differ slightly. Traditional saunas create a more intense heat stress, potentially leading to greater cardiovascular adaptation. However, infrared saunas have also shown positive effects on blood pressure and heart health in studies.
Both sauna types promote sweating and detoxification. Some proponents claim infrared saunas produce a deeper, more detoxifying sweat, though scientific evidence for this is limited. The key is that both types make you sweat, which helps eliminate toxins.
Infrared saunas may have an edge for deep tissue pain relief, as the infrared waves can penetrate 3-4cm into the body. This makes them popular for treating chronic pain conditions, fibromyalgia, and muscle recovery.
Infrared saunas are generally:
Less expensive to purchase and install
Easier to fit in smaller spaces
More energy-efficient to operate
Faster to heat up (15-20 minutes vs 30-45 minutes)
Traditional saunas typically require:
More space and ventilation
Higher initial investment
More energy to operate
Professional installation in many cases
The experience differs significantly between the two types. Traditional sauna enthusiasts often prefer the intense heat, the ritual of throwing water on stones, and the authentic cultural experience. Infrared sauna users often appreciate the gentler heat, which some find more tolerable for longer sessions.
Choose a traditional sauna if you:
Enjoy intense heat and higher temperatures
Appreciate the traditional Finnish sauna experience
Want the option of adding humidity
Have the space and budget for installation
Prefer the social aspect of larger shared saunas
Choose an infrared sauna if you:
Are sensitive to extreme heat
Have limited space at home
Want a more budget-friendly option
Primarily seek deep tissue pain relief
Prefer longer, more gentle sessions
There's no definitively 'better' option between traditional and infrared saunas. Both provide significant health benefits and can be valuable additions to your wellness routine. The best choice depends on your personal preferences, health goals, practical constraints, and budget. If possible, try both types before making a decision. Many people end up appreciating both for different reasons.
