What Is the Difference Between Traditional (Steam) Saunas and Infrared Saunas?

People have been using heat for health for thousands of years. People all over the world have known for a long time that exposing yourself to heat on purpose can relax your muscles, clear your mind, and make you feel better. That old knowledge has turned into two different types of technology: traditional (steam) saunas and infrared saunas.

Both put the body into a hyperthermic state by raising core body temperature to trigger beneficial physiological responses, but they do so in very different ways.

Traditional saunas heat the air around you to very high temperatures. Infrared saunas, on the other hand, use radiant energy that goes directly into your body. This difference has an effect on everything, including comfort, session length, costs, and health benefits.

This guide explains how each type works, what they feel like, what their benefits are, and who they are best for. We at Health Mate Sauna think that people should make decisions based on their real health goals, not on marketing hype.

What Is a Traditional Sauna?

How Saunas Work the Old-Fashioned Way

High-capacity electric heaters (4.5 to 9.0 kW) filled with conductive stones, such as peridotite, are used in traditional saunas. Electric elements heat stones to more than 500°F, which then heats the air around them. Convection moves this hot air around, and eventually it warms your body as it comes into contact with it.

Löyly, which means pouring water over very hot rocks to make steam bursts, is the most important ritual. The baseline environment is dry (less than 10% humidity), but these steam bursts raise the humidity to 20–40%, which stops sweat from evaporating and makes you sweat a lot.

Normal Setting and Experience

The temperature in a traditional sauna is between 150°F and 195°F. The environment is thermally stratified, which means that the ceiling can be 20 to 30 degrees hotter than the floor. This is why there are benches on different levels.

The experience is short and very intense. Steam makes a “thermal sting,” which is sudden, very hot heat that doesn’t go away because of the humidity. Most people can only handle sessions that last 10 to 20 minutes. A lot of people say that this endurance challenge helps them mentally.

Cultural Background

The Finnish word “sauna” means “bathhouse,” which were the cleanest rooms in homes and were used for bathing, giving birth, healing, and getting together with others. Traditional saunas are part of Northern European culture and are still important for social health.

What Is an Infrared Sauna?

How Do Infrared Saunas Work?

Infrared saunas use special emitters to make infrared light wavelengths, which are electromagnetic radiation that is just outside of visible red light. These waves can move through air without heating it up, and your body can directly absorb them through conversion. When infrared energy hits water molecules in tissue, they vibrate and make heat inside.

This lets you sweat a lot even when the temperature is much lower, usually between 110°F and 150°F. Heat goes through the skin barrier instead of just warming the surface. This gives therapeutic benefits without the need for very hot air.

Different Kinds of Infrared Wavelengths

• Near-Infrared (NIR) – Near-Infrared (NIR) goes through the layers of skin, stimulating mitochondria to make energy for cells, encouraging collagen production, and speeding up the healing of wounds.
• Mid-Infrared (MIR) – Mid-Infrared (MIR) goes deeper into soft tissue, making blood vessels bigger, improving blood flow, and easing inflammation in muscles and joints.
• Far-Infrared (FIR) – Far-Infrared (FIR) has the longest wavelength and interacts with water molecules. FIR absorption works very well because bodies are made up of 60–70% water. This wavelength causes deep hyperthermia, detoxification, muscle relaxation, and conditioning of the heart and blood vessels.

Most home infrared saunas only use far-infrared light, but more advanced full-spectrum infrared systems use all three types of light.

Normal Experience

Infrared saunas feel very different. The air temperature stays between 120°F and 140°F, which is warm but not too hot. The air is still breathable, and there is no humidity or steam. The heat is soft and gets through.

Most people can easily spend 30 to 45 minutes in an infrared sauna. Longer sessions let your heart rate stay high and your body sweat for a longer time. The setting is good for reading, meditating, or just relaxing.

Air Heat vs. Radiant Heat: How They Work

How Heat Moves in a Traditional Sauna

Convection is how traditional saunas work: heater → air → body. Because air doesn’t conduct heat well, it needs to get to 180°F or higher. Your skin gets very hot before your core temperature rises, which makes you feel like you’re “baking” and makes your body cool down quickly.

Transfer of Heat by Infrared

Infrared uses direct radiant energy from the emitter to the body. Waves can go through air without making it very hot. When energy hits tissue that is rich in water, it turns into heat.

Traditional heat only goes a few millimeters into the body, but far-infrared waves can go up to 1.5 inches into muscle and subcutaneous tissue. The Journal of Applied Physiology published research that showed muscle temperature rises by 1.4 to 3.4 cm during far-infrared exposure. This warms tissue without making the air very hot.

Why This Is Important

Infrared warms deep tissues while keeping the air cool. This makes sessions last longer, makes breathing easier, and helps you target muscle and joint pain better. Traditional saunas are great for getting your heart and lungs in shape, but they can be too hot for some people.

Comparing Temperature and Humidity

To work, traditional saunas need to be between 150 and 195 degrees Fahrenheit. The baseline humidity is surprisingly low (less than 10%), but löyly raises it to 20–40%, which intensifies the “wet bulb” effect and shortens sessions.

Infrared saunas keep a steady dry heat between 120°F and 140°F. Without steam, the environment stays the same. Dry heat makes it easy for sweat to evaporate, which makes sessions of 30 to 45 minutes comfortable.

An infrared session at 120°F can make you sweat as much or more than a traditional session at 180°F because heat works inside the body, not just on the skin.

Health Benefits: What They Have in Common and What Makes Them Different

Benefits That Are Shared

Both dilate blood vessels, reduce arterial stiffness, and help keep blood pressure in a healthy range. The heart rate goes up to 100–150 beats per minute, which is like doing moderate aerobic exercise. Both help the body get rid of toxins by making you sweat, lowering stress, improving circulation, and helping your muscles heal.

Benefits of a Traditional Sauna

Very hot weather makes for very hard cardiovascular workouts. The Kuopio study found that using a traditional sauna four to seven times a week was linked to a big drop in the risk of sudden cardiac death and stroke.

Traditional saunas are great for helping with breathing. Steam inhalation clears up congestion, calms asthma, and eases bronchitis. Research indicates enhancements in forced vital capacity among individuals with obstructive lung disease.

Benefits of Infrared Saunas

Infrared is great for easing pain and helping muscles and bones heal. Far-infrared penetrates 3–4 cm and directly warms joints and muscles, which makes them less stiff. Studies show that FIR therapy speeds up recovery from delayed onset muscle soreness and lowers markers of muscle damage that are caused by exercise.

For long-term illnesses like fibromyalgia and rheumatoid arthritis, infrared’s ability to warm deep tissue provides steady relief. Waon therapy with infrared helps people with chronic heart failure by making their hearts work better through gentler conditioning.

Studies show that infrared sweat may have up to 20% toxins (cholesterol, fat-soluble toxins, heavy metals), while regular sweat only has 3%. Because infrared waves can get through subcutaneous fat, where toxins are stored, they may be better at moving around compounds that are stuck there, meaning infrared saunas can help with detoxification.

Full-spectrum infrared saunas with near-infrared light may help reduce wrinkles and improve the texture of the skin by increasing the production of collagen and elastin. These are benefits that traditional saunas can’t offer.

Important: Using a sauna is good for your health, but it’s not a medical treatment. Before starting sauna therapy, talk to a doctor, especially if you have heart problems, are pregnant, or are taking medications that affect how your body regulates temperature.

Comfort, Ease of Use, and User Experience

Traditional saunas take 30 to 45 minutes to heat up, while infrared saunas only take 15 to 30 minutes. Infrared is easier for people who are sensitive to heat, older adults, and people with mild heart problems to use because it works at lower temperatures (120°F to 140°F).

The breathable air gets rid of the “suffocation factor” that some people feel when they are in a traditional sauna at 190°F. You won’t be able to use a traditional sauna regularly if you can’t handle extreme heat, which means you won’t get its benefits.

The comfort of infrared makes it possible to use it every day, turning sauna therapy from a once-in-a-while ritual into a regular wellness habit.

Installation, Space, and Energy Savings

Traditional saunas need 220–240V power and separate 30–60 amp circuits, which means hiring licensed electricians, getting permits, and possibly upgrading the electrical panel, which can add $500–$1,500 to the cost. To keep moisture under control, they need floors, drains, and ventilation that won’t get wet.

Most infrared saunas for homes are plug-and-play, which means they work with regular 110–120V household current. You don’t need an electrician to plug them in. Because they don’t make steam, they don’t need floor drains or outside vents, so they can be safely installed on any type of flooring in bedrooms, basements, or spare rooms.

Infrared saunas use 1.5 to 2.5 kW of power, while traditional saunas use 4.5 to 9.0 kW. This is one-third to one-half the power. Infrared runs cost $5 to $10 a month for three sessions a week, while traditional runs cost $20 to $35. Infrared saves $1,500 to $2,500 on electricity over ten years.

Taking Care of and Owning Something for a Long Time

In humid places like traditional saunas, you have to be careful about mold. You need to scrub, clear the drains, and take care of wood staining on a regular basis. Most of the time, heating elements need to be replaced every 5 to 10 years.

Infrared saunas don’t need much care. Bacteria don’t grow well in dry places. Cleaning the benches with a solution of water and vinegar is part of the routine care of infrared saunas.

Advanced heater technology is important. Health Mate’s Tecoloy™ heaters are made of solid-state Incoloy alloy rods that don’t break when they get hot and come with lifetime warranties. Health Mate’s 100% solid eucalyptus wood is antimicrobial, resistant to rot, has a high density that keeps it from warping, and is hypoallergenic.

Price Comparison

The cost of a traditional sauna kit is between $4,000 and $10,000, plus $500 to $1,500 for installation. Infrared saunas that you put together yourself cost between $2,500 and $8,000.

Infrared is cheaper to run, costing $0.20 to $0.40 per session compared to $0.75 to $1.50 for traditional. Over the course of 10 to 15 years, infrared is cheaper because it doesn’t need to be installed, saves $200 a year on energy costs, and needs less maintenance.
