Is Infrared or Finnish Sauna Better?

Stuck between the steamy tradition of Finnish saunas and the gentle glow of infrared? When it comes to outdoor saunas, infrared saunas win for detox and recovery, while Finnish saunas rule for heart health. Both heat up your wellness—read on to discover which sauna truly suits your vibe.

Understanding the Difference in Heat Technology and Experience

Traditional Finnish Saunas: High Heat and Humidity

A traditional Finnish sauna is a wooden room heated by stones or electric heaters. The air inside is dry, with temperatures ranging from 70°C to 100°C. You can pour water over the hot stones to create steam and briefly raise the humidity. This creates a sharp, warming experience many people love.

Finnish saunas have been part of Nordic life for generations and are used for both relaxation and social bonding.

How Convection Works: Heating the Air to Heat the Body

Finnish saunas work using convection heat. The heater warms the air, which then heats your body. This traditional method results in high ambient temperatures and an intense, whole-room heat experience.

It may take longer to heat up the space, but once it does, it creates a consistent environment. This is part of the reason Finnish saunas are so effective at encouraging sweat and circulation.

The "Löyly" Experience: Using Steam for Respiratory Health

“Löyly” refers to the soft steam created when water hits the hot stones. This temporary boost in humidity can soothe the airways and ease breathing. Many sauna-goers find the sudden steam burst invigorating.

It’s an important ritual in traditional Finnish sauna culture. It also adds a social and sensory dimension to the sauna session.

Temperature Ranges: Why 80°C–100°C is the Finnish Standard

Finnish saunas usually operate between 80°C to 100°C. This high heat level promotes deep sweating and detox. The intensity also supports cardiovascular health by raising heart rate and improving circulation.

Not everyone enjoys the heat, but those who do often find it addictive. It’s considered the “classic” sauna experience.

Infrared Saunas: Direct Radiant Heat and Lower Temps

Infrared saunas offer a modern take on the sauna tradition. Instead of heating the air, infrared saunas use special panels to emit radiant heat that warms the body directly. The result is a milder room temperature but still a deeply warming effect on the skin and muscles.

It’s a very different sensation from sitting in a traditional dry sauna.

How Light Waves Work: Heating the Body from the Inside Out

Infrared saunas use light waves to warm your body from the inside out. This allows for a more gradual and tolerable experience, even for longer sessions. Your body begins to sweat at a lower ambient temperature.

This is why infrared users often feel they get a better detox without enduring extreme heat. The deeper heat penetration also has other wellness benefits.

Dry Heat Benefits: Why People Who Hate Humidity Choose Infrared

Some people find the dry, high heat of Finnish saunas uncomfortable. Infrared saunas offer a solution—less intense air temperature with a still-powerful effect. This makes them easier to tolerate, especially for beginners or those with heat sensitivity.

Many users report feeling deeply relaxed rather than overwhelmed. It’s also a quieter and more low-maintenance sauna session.

Pre-Heat Times: Comparing Efficiency and Energy Consumption

Infrared saunas typically heat up faster than Finnish saunas. Because they don’t need to warm the air, they reach effective temperatures quickly. They’re also more energy-efficient since less power is needed overall.

This makes them ideal for home use or frequent sessions. Over time, this can also mean lower electricity bills.

Comparing Health Benefits and Practical Logistics

Which is Better for Your Health Goals?

Both sauna types provide significant wellness benefits. However, the kind of heat they produce affects the body differently. Some benefits overlap, while others are more specific to each sauna type. Here’s how they compare when it comes to health goals.

Cardiovascular Performance and Longevity: The Finnish Research

Finnish saunas have been studied for their impact on heart health. Regular use can improve blood flow, reduce blood pressure, and support long-term cardiovascular function.

A study published by the Journal of the American College of Cardiology showed regular sauna use is linked to reduced heart disease risk. This is likely due to the high heat and circulatory benefits. It’s especially helpful for those with a sedentary lifestyle or poor circulation.

Muscle Recovery and Deep Tissue Relaxation: The Infrared Advantage

Infrared saunas are popular among athletes and those with chronic pain. The gentle, deep-penetrating heat helps ease muscle soreness and joint stiffness. It reduces inflammation and promotes faster recovery after workouts or injury. Because the heat targets deep tissue, it’s highly effective without requiring high room temperatures.

This makes infrared saunas more accessible for people who can’t tolerate extreme heat.

Detoxification and Weight Loss Myths vs. Realities

Both saunas make you sweat, which helps release toxins through the skin. However, the lower temperature and longer duration of infrared sessions can result in a more sustained sweat. While some claim sauna use burns calories or promotes weight loss, results vary.

 Saunas should support a healthy lifestyle—not replace diet and exercise. Still, many people feel “lighter” and more refreshed after regular sauna use.

Installation, Budget, and Home Requirements

Power Demands: 13-Amp Plug-and-Play vs. 32-Amp Hardwiring

Infrared saunas are typically easier to install. Most models use a standard 13-amp plug, which means no major electrical work is needed. In contrast, Finnish saunas often require a 32-amp hardwired connection.

This may mean hiring a licensed electrician, especially for larger or commercial-grade models. Installation costs can vary based on your setup.

Indoor vs. Outdoor Suitability: Weatherproofing and Moisture Control

Outdoor saunas—whether Finnish or infrared—need proper protection against the elements. Finnish saunas often need more insulation and ventilation due to the higher heat and humidity. Infrared saunas can be installed in smaller, more flexible spaces.

However, both require moisture-resistant materials and stable flooring. A well-sealed cabin will extend the life of your sauna significantly.

Maintenance and Lifespan: Which System Lasts Longer?

Infrared saunas are generally lower-maintenance. They have fewer parts and don’t require stone replacement. Finnish saunas need periodic cleaning, checking of the heater, and sometimes replacing stones. 

In terms of durability, both can last many years with proper care. However, infrared panels may need replacement after extensive use, while Finnish heaters are built for longevity.

The Final Verdict: Choosing the Right Sauna for Your Lifestyle

Best for Athletes and Biohackers: The Infrared Choice

Infrared saunas are ideal for recovery, chronic pain relief, and detox. Their efficient design and lower heat make them appealing for regular personal use. If you’re after a modern, low-maintenance, and energy-efficient wellness tool, this might be your match. 

Great for biohackers, gym-goers, and anyone who wants health support without the heat stress.

Best for Social Wellness and Traditionalists: The Finnish Choice

Finnish saunas are perfect for those who love tradition, ritual, and a social vibe. The high heat and löyly experience are unmatched. They offer deep relaxation, cardiovascular benefits, and a sense of cleansing unlike any other.

For those who enjoy heat bathing as a cultural or meditative practice—especially in outdoor saunas—the Finnish sauna is hard to beat.
