Infrared saunas heat the body directly through radiant panels rather than warming the surrounding air first, and that difference is what draws a growing number of homeowners toward them as a home wellness investment. They run at lower temperatures than traditional saunas, fit into spare rooms and home gyms, and offer a gentler way to build a regular heat therapy habit.
Key Takeaways
- Infrared saunas typically operate between 110 and 135°F, compared with 150 to 195°F for traditional saunas.
- Research suggests possible benefits for muscle recovery, chronic pain, relaxation, sleep and heart health, though most long-term evidence comes from traditional saunas.
- Beginners should start with short sessions of around five to 10 minutes and build up gradually, staying well hydrated.
- People who are pregnant, have heart conditions or blood pressure issues, or have multiple sclerosis should speak to a doctor before using a sauna.
- Infrared saunas suit indoor installation, but electrical requirements, room size and flooring should all be confirmed before purchase.
How Infrared Saunas Work

The main difference between infrared and traditional saunas is how the heat reaches you. Understanding that difference makes it easier to judge which format suits your space and how you plan to use it.
Infrared vs Traditional Saunas
A traditional sauna uses a wood-burning, gas or electric heater to raise the air temperature in the room, which then warms your body. An infrared sauna uses infrared lamps or panels to warm your body more directly, without heating the air to the same degree. Northwestern Medicine compares it to how sunlight warms your skin on a cool day, without the harmful UV rays.
That lets infrared saunas run at much lower air temperatures. According to Cleveland Clinic, infrared saunas operate at 110 to 135°F, while traditional saunas run between 150 and 195°F. Functional medicine specialist Melissa Young, MD, notes that both will make you sweat, but infrared tends to feel gentler and more comfortable.

Panel Types and Spectrum
Not all infrared saunas use the same wavelengths. Mayo Clinic notes that infrared saunas are sometimes called far-infrared saunas, with “far” describing where the waves sit on the light spectrum. Some systems go further: Northwestern Medicine explains that full-spectrum infrared combines far, mid and near wavelengths for a broader heating effect.
Health Benefits of Infrared Saunas
Infrared saunas are linked with a range of possible health benefits, but the evidence is still developing. Northwestern Medicine notes that most long-term research has been done on traditional saunas, and that infrared research is mostly limited to small, short-term studies. Mayo Clinic says studies have found some evidence that infrared saunas may help with conditions such as high blood pressure, heart failure and arthritis, but that larger, more rigorous studies are needed.
Heart Health
Within minutes in an infrared sauna, your blood vessels widen, blood flow increases and your heart rate rises. Cleveland Clinic describes this as similar to the effects of exercise, a kind of “passive cardio,” though it stresses that some studies suggest sauna use may support cardiovascular function and that more research is needed, especially on infrared saunas. Both Cleveland Clinic and Northwestern Medicine are clear that a sauna session isn’t a substitute for a workout.
Muscle Recovery

The added blood flow that comes with heat exposure may help ease muscle soreness after exercise by delivering oxygen and nutrients to tired muscles, according to Cleveland Clinic. Nike points to a small 2015 study of 10 physically active men, which found that 30 minutes in an infrared sauna after a tough endurance workout improved neuromuscular recovery.
Pain and Joint Comfort
Some research suggests infrared sauna use may help reduce pain and stiffness, especially for people with conditions like rheumatoid arthritis, according to Northwestern Medicine. Nike cites a small 2008 study in which patients with rheumatoid arthritis and ankylosing spondylitis felt more comfortable after eight sauna sessions over four weeks. Cleveland Clinic notes that many studies on chronic pain are small and need confirming.
Relaxation and Sleep
Many people find saunas relaxing, and some research suggests they may help reduce stress and improve mood. Sleep may benefit too: Cleveland Clinic explains that your body naturally cools down after an infrared session, and when used in the hours before bed, that cooling may support your body’s natural temperature drop ahead of sleep. More research is needed to understand exactly how saunas affect sleep.

Separating Fact From Marketing
Some claims about infrared saunas go further than the evidence. Northwestern Medicine warns that much infrared marketing borrows from traditional sauna research and may overstate the benefits. It also lists sauna detox as a myth: sweating removes only small amounts of toxins, and the liver and kidneys do most of that work. Healthline adds that using an infrared sauna doesn’t burn body fat.
Using an Infrared Sauna Safely
Infrared saunas are generally safe for most healthy adults, and Mayo Clinic notes that no harmful effects have been reported. Even so, heat exposure carries some risk, so it pays to start gently and know when to hold back.
Session Length and Frequency
Cleveland Clinic suggests starting at around 110°F for five to 10 minutes, then building from there, and keeping sessions to around 20 to 30 minutes even once you’re experienced. Northwestern Medicine says most people use infrared saunas two to four times a week for 15 to 30 minutes per session, and notes that most studies use 15-minute sessions.
Hydration matters throughout. Drink water before, during and after a session, avoid alcohol, and get out straight away if you feel dizzy or nauseated. Healthline advises seeking medical attention if you develop a headache, a fever of 104°F or higher, confusion or a racing heart after a session, as these can be signs of heatstroke.
Who Should Check With a Doctor First
Cleveland Clinic advises caution or avoidance if you have multiple sclerosis, are pregnant, are trying to conceive, or are unwell. Northwestern Medicine adds that people with heart conditions or high blood pressure should discuss sauna use with their doctor, and Healthline flags low blood pressure as another reason to avoid saunas. Nike lists severe aortic stenosis, chest pain from heart disease, and a recent heart attack or stroke as further reasons to stay out.
Infrared Saunas at Home
Infrared saunas have become popular in wellness spaces, fitness centers and homes. Their lower operating temperature and compact builds make them a practical option for indoor spaces where a traditional sauna room would be harder to fit.
Standalone Cabins and Room Kits
There are two main ways to bring infrared heat into your home. A standalone infrared cabin arrives ready to assemble, and the infrared saunas at Heracles Wellness are designed to be quick to heat up, with space-saving builds for a variety of home settings. Alternatively, infrared room kits include infrared panels and essential components, letting you turn a spare room, home gym or wellness area into a working infrared sauna.
Planning Your Installation
A few details are worth settling before your sauna arrives:
- Room dimensions: Make sure the cabin fits your floor space, with the clearance the manufacturer specifies on all sides.
- Electrical supply: Confirm the unit’s voltage and amperage requirements with the manufacturer, and have a qualified electrician check your panel capacity and install any supply needed.
- Ventilation: The room should have adequate air circulation, even though no flue is needed.
- Flooring: Check that the floor can support the unit’s weight, particularly in upper-floor rooms.
Choosing the Right Infrared Sauna
Choosing an infrared sauna involves more than comparing prices. Capacity, spectrum and where you buy all affect how well the unit fits your home and routine.
Capacity
Infrared saunas range from compact one-person cabins to larger multi-person units. A one or two-person model suits solo or paired sessions, while a larger cabin suits families or households where several people use it in a day.
Spectrum and Hybrid Options
Full-spectrum saunas deliver near, mid and far infrared in a single session. The Finnmark FD-1 Full-Spectrum Infrared Sauna, listed at $4,695.00, is one example. If you want both infrared warmth and steam, hybrid models combine the two. The Finnmark FD-5 Trinity XL Infrared and Steam Sauna Combo, listed at $8,995.00, pairs infrared with steam in one cabin. Combination units broaden the experience but may also add to the electrical load, so confirm the requirements before ordering.
Buying With Confidence
A sauna is a significant purchase, so it’s worth buying from an authorized dealer with the original manufacturer’s warranty in place. Heracles Wellness is an authorized dealer, includes the manufacturer warranty on every purchase, and ships across the continental US.
Pairing an Infrared Sauna With a Cold Plunge
Many people pair sauna sessions with cold exposure as part of a contrast routine. If you plan to do this, give your body a moment to adjust between the two. Nike shares a tip from nutritionist Shaina Painter to cool down gradually after a sauna session, taking a two to five-minute break before a cold shower or plunge to avoid swings in blood pressure. An infrared sauna’s compact footprint also makes it easier to place near a cold plunge without major building work.
