The world of wellness has embraced sauna therapy for centuries, but modern technology has introduced an important choice for health enthusiasts: traditional or infrared saunas. Traditional saunas use heated stones or elements to warm the air around you, creating that classic hot, steamy environment. Infrared saunas, by contrast, use invisible light waves to directly heat your body without significantly warming the surrounding air. What is Sauna Therapy? has become a frequent question as more people discover these contrasting approaches to heat-based wellness.
This comprehensive guide will help you navigate the differences between these two popular sauna types, examining everything from their operating mechanisms and health benefits to practical considerations like cost and maintenance. By the end, you’ll have a clear understanding of which sauna experience aligns best with your wellness goals, health needs, and lifestyle preferences.
How do infrared and traditional saunas work?
Understanding the fundamental differences in how each sauna type operates is essential before making any decisions about which one might better serve your wellness routine.
Traditional saunas work through convection heat, typically using heated rocks or electric elements to warm the air to temperatures ranging from 170-200°F (77-93°C).
The high ambient temperature then heats your body from the outside in. These saunas often include water that can be poured over hot stones to create steam, increasing humidity and intensifying the heat sensation. This centuries-old approach, perfected in Finnish culture, creates an immersive hot-air experience that opens pores and induces profuse sweating.
Infrared saunas operate quite differently, using infrared heaters to emit radiation that directly warms your body without significantly heating the surrounding air.
Operating at lower temperatures of 120-140°F (49-60°C), these saunas warm you from the inside out as the infrared waves penetrate skin tissue directly. This allows for a more comfortable experience for heat-sensitive individuals while still producing therapeutic sweating.
Infrared wavelengths explained
Infrared saunas utilize different wavelengths along the infrared spectrum, each offering specific benefits:
- Near-infrared (NIR): The shortest wavelength penetrates the skin’s surface and is believed to help with wound healing and skin rejuvenation
- Mid-infrared (MIR): Penetrates deeper tissue, potentially helping with muscle recovery and improved circulation
- Far-infrared (FIR): Reaches deepest into the body, producing the most intense sweating and potentially supporting detoxification processes
The setup and installation requirements differ substantially between these sauna types. Traditional saunas typically require dedicated space, proper ventilation, and sometimes specialized electrical work. They’re often constructed from specific woods like cedar or hemlock that withstand high heat and humidity. Infrared saunas, meanwhile, generally require less space, standard electrical outlets, and don’t need specialized ventilation, making them more adaptable to different home environments.

Health benefits: infrared vs traditional sauna
Both sauna types deliver impressive wellness advantages, though they may excel in different areas based on their heating methods.
Traditional saunas have centuries of use supporting their benefits. The intense heat creates a pseudo-fever state that may strengthen immune function while the profuse sweating helps eliminate toxins through the skin. The high temperatures dilate blood vessels, potentially improving circulation and cardiovascular health. Research from Finland, where traditional sauna use is deeply ingrained in the culture, suggests regular sessions may support longevity and reduce cardiovascular disease risk.
The traditional sauna experience also creates a distinct mental health benefit through the intense heat-then-cool cycle that stimulates endorphin release. Many users report profound stress relief, improved sleep quality, and enhanced recovery after intense physical activity. The social aspect of traditional saunas in many cultures adds a community wellness dimension that shouldn’t be overlooked.
Infrared saunas provide many similar benefits through a different mechanism. The direct heating of body tissues without extreme ambient temperatures makes them accessible to those who find traditional saunas uncomfortable. The deeper tissue penetration of infrared waves may offer enhanced detoxification as they reach fat cells where many toxins are stored.
For muscle recovery and chronic pain management, infrared saunas show particular promise. The penetrating heat can reach deeper muscular tissues, potentially releasing tension and increasing blood flow to injured areas. Some research suggests infrared therapy may help with conditions like fibromyalgia, arthritis, and chronic fatigue syndrome, though more studies are needed for definitive conclusions.
Both sauna types support relaxation and stress reduction, though some users report infrared sessions feel less intense while still delivering therapeutic benefits. Benefits of Regular Sauna Use extend beyond the physical to include significant mental wellness advantages, regardless of which heating mechanism you choose.
Comparing research: what does science say?
Scientific research offers valuable insights into how these sauna types affect various aspects of health, though studies focusing specifically on comparing the two are still emerging.
For cardiovascular health, traditional saunas have the most robust research. Long-term studies from Finland show regular traditional sauna use is associated with reduced risk of fatal cardiovascular events, hypertension, and stroke. The intense heat stress appears to condition the cardiovascular system similarly to moderate exercise, improving endothelial function and vascular flexibility. One notable study followed men for over 20 years and found those using saunas 4-7 times weekly had significantly lower rates of sudden cardiac death compared to once-weekly users.
Infrared sauna research, while newer, shows promising cardiovascular benefits as well. Several studies suggest infrared sessions may help lower blood pressure and improve arterial stiffness. The more comfortable temperatures might make infrared saunas accessible for those with heat sensitivity or certain cardiovascular conditions, though anyone with heart issues should consult their physician before beginning any sauna routine.
For pain management and recovery, infrared saunas appear particularly effective. Research indicates far-infrared therapy may reduce pain in conditions like rheumatoid arthritis and fibromyalgia. The direct tissue penetration seems to affect pain mediators and reduce inflammation at a deeper level. Traditional saunas also show benefits for muscle recovery, though through the different mechanism of overall body temperature elevation.
Mental health research suggests both sauna types provide significant benefits. The heat stress induces changes in neurochemicals like endorphins, potentially explaining the mood enhancement many users report. Studies show regular sauna sessions may reduce symptoms of depression and anxiety, improve sleep quality, and enhance overall well-being. Traditional saunas might have a slight edge in some mental health applications due to their more intense heat experience and often more social environment.
Regarding detoxification, both sauna types promote sweating, which can help eliminate certain toxins through the skin. However, claims about “deep detoxification” require more scientific validation. The liver and kidneys remain the body’s primary detoxification organs, with sweating providing a supportive rather than primary role in eliminating toxins.
It’s important to note that sauna research often faces limitations including small sample sizes, varying protocols, and difficulty in creating controlled studies. Additionally, most longevity research has focused on traditional saunas simply because they’ve been used longer and more consistently in populations like the Finnish, where long-term health data is available.

Practical considerations: cost, installation & maintenance
Beyond health benefits, practical factors like budget, space requirements, and ongoing costs play crucial roles in determining the best sauna option for your lifestyle.
Initial purchase costs vary significantly between sauna types. Traditional saunas typically range from $3,000 to $8,000 or more, depending on size, quality, and features. Custom-built traditional saunas can exceed $15,000. Infrared saunas generally cost less, with quality options available from $1,500 to $5,000. The price difference largely reflects the more complex construction and materials needed for traditional saunas to withstand high temperatures and humidity.
Installation requirements present another important distinction. Traditional saunas often require:
- dedicated space with proper floor drainage
- specialized electrical work (240V circuits for many models)
- proper ventilation systems
- potentially water-resistant flooring modifications
- professional installation in many cases Infrared saunas, by comparison, generally need:
- standard 120V electrical outlet
- minimal ventilation requirements
- less specialized space preparation
- often can be self-installed with basic tools
Energy consumption represents an ongoing cost difference. Traditional saunas require significant electricity to heat stones and air to high temperatures, typically consuming between 6-12 kW per hour. They also need longer warm-up times (30-45 minutes) before use. Infrared saunas operate more efficiently, using approximately 1.5-3 kW per hour and warming up in just 10-15 minutes. This efficiency difference can translate to notably lower utility bills over time.
Maintenance requirements also differ. Traditional saunas need regular cleaning to prevent mold growth from humidity, occasional wood treatment, and periodic replacement of heating elements or stones. Infrared models generally require simpler maintenance—mainly wiping down surfaces and occasionally replacing infrared emitters, which typically last many years.
Space considerations may influence your decision significantly. Traditional saunas typically require more room—a minimum of 4×5 feet for a small model and often larger for a satisfying experience. Infrared saunas can function in smaller spaces, with some compact models fitting in areas as small as 3×3 feet, making them more versatile for homes with limited space.

Safety, risks, and who should avoid each sauna
While sauna therapy offers numerous benefits, understanding the risks and contraindications helps ensure a safe experience tailored to your health situation.
Both sauna types present some common risks, primarily related to heat exposure:
- dehydration if fluid intake isn’t adequate
- dizziness or fainting from rapid blood pressure changes
- overheating, especially for newcomers unaccustomed to heat therapy
- skin irritation in sensitive individuals
Traditional saunas carry slightly higher risks of dehydration and overheating due to their more extreme temperatures. The intense heat may be problematic for those with heat sensitivity or certain cardiovascular conditions. The higher temperatures can also make breathing more difficult for people with respiratory issues.
Infrared saunas, while generally considered gentler, have their own considerations. Some users express concern about electromagnetic field (EMF) exposure from infrared heaters, though quality models now feature low-EMF technology. The direct heating of tissues may potentially be problematic for those with certain implanted medical devices or active inflammation, though research on specific contraindications remains limited.
Specific populations should exercise caution with both sauna types:
- pregnant women (consult healthcare provider first)
- people with unstable heart conditions
- those with low blood pressure prone to fainting
- individuals taking medications that affect heat tolerance or sweating
- people with certain skin conditions that might worsen with heat
- anyone with implanted medical devices (especially with infrared saunas)
- children, whose temperature regulation systems are still developing
Essential safety tips for any sauna experience include:
- hydrate well before, during (if possible), and after sessions
- start with shorter sessions (5-10 minutes) and gradually increase
- exit immediately if feeling dizzy, nauseous, or excessively uncomfortable
- avoid alcohol before and during sauna use
- wait at least one hour after eating before sauna sessions
- shower after sessions to remove toxins released through sweat
- consult healthcare providers before beginning regular sauna use, especially with pre-existing conditions
When used appropriately with these precautions in mind, both sauna types can be incorporated safely into most wellness routines. The key is matching the sauna experience to your personal health profile and comfort level.
Choosing the best sauna for your wellness goals
Selecting the ideal sauna type ultimately depends on aligning your specific health objectives, practical circumstances, and personal preferences.
For cardiovascular health improvement, both sauna types offer benefits, though traditional saunas have the most established research backing their heart-health effects. The intense heat stress creates a cardiovascular training effect similar to moderate exercise. If improving heart health is your primary goal and you can tolerate high temperatures, traditional saunas might have a slight edge.
Those focused on pain management and muscle recovery might find infrared saunas particularly effective. The deeper penetration of infrared waves can reach muscular tissues directly, potentially offering more targeted relief for chronic pain conditions, arthritis, or post-workout recovery. Athletes often prefer infrared saunas for this reason, along with their shorter warm-up times that fit better into busy training schedules.
If stress reduction and mental wellness are your priorities, consider your temperature preferences. Some find the intense heat of traditional saunas creates a more powerful “reset” effect, forcing complete mental presence and followed by profound relaxation afterward. Others prefer the gentler experience of infrared saunas, allowing longer sessions without temperature discomfort while still receiving stress-reduction benefits.
For detoxification purposes, both sauna types promote beneficial sweating. Infrared advocates suggest the direct tissue heating may help release fat-stored toxins more effectively, though scientific confirmation of this specific advantage remains limited. Those with chemical sensitivities or detoxification concerns might explore both types through trial sessions before committing.
Practical lifestyle considerations often become deciding factors:
- budget constraints typically favor infrared options
- limited home space generally makes infrared more practical
- heat sensitivity usually points toward infrared’s lower temperatures
- desire for authentic traditional experience may justify higher costs
- energy efficiency concerns favor infrared technology
- commitment to traditional wellness practices might prioritize classic sauna design
Before making a significant investment, consider trying both sauna types multiple times. Many spas, gyms, and wellness centers offer both experiences, allowing you to compare their effects on your body and mind directly. Pay attention to how you feel during and after each session, which better addresses your specific health concerns, and which experience you find yourself looking forward to repeating.
Remember that either sauna type, used consistently and appropriately, will likely provide significant wellness benefits over no sauna use at all. The “perfect” choice is the one that fits seamlessly into your lifestyle, making regular sessions sustainable long-term.
Conclusion
