Infrared saunas have become one of the most popular wellness investments for homes, studios, and professional recovery spaces. Many people first hear about them through fitness recovery, relaxation routines, or wellness clinics, but choosing the right infrared sauna can feel overwhelming. There are different heater types, safety terms like “low-EMF,” size decisions, installation requirements, and comparisons with traditional saunas.
This guide explains everything you need to know before buying an infrared sauna so you can make a confident and informed decision.
1. What Is an Infrared Sauna?
An infrared sauna uses infrared light to warm your body directly instead of heating the air around you. Traditional saunas heat the room to very high temperatures, while infrared saunas typically operate at lower temperatures and rely on radiant heat panels that penetrate the skin more directly.
Because the heat is delivered differently, many users find infrared saunas easier to tolerate, especially during longer sessions. Infrared units generally run around 45–60°C (113–140°F), compared to traditional saunas that can reach 80–100°C.
The goal is still the same: to warm the body, increase circulation, encourage sweating, and provide relaxation.
For most healthy individuals, infrared sauna use is considered safe when used responsibly, though people with medical conditions should consult a doctor before starting sauna routines.
2. Types of Infrared Saunas
Not all infrared saunas are the same. Understanding the heater types helps you choose the right experience.
Near-Infrared
Near-infrared heaters produce shorter wavelengths that stay closer to the skin surface. They are sometimes used for targeted warming or therapy-focused setups.
Far-Infrared
Far-infrared heaters are the most common. They produce longer wavelengths that warm the body more gently and evenly. These saunas are typically used for relaxation and daily wellness routines.
Full-Spectrum Infrared
Full-spectrum saunas combine near, mid, and far infrared heaters. This allows more flexibility in temperature control and heating style. They are often used in high-end or professional installations.
Each type can feel different in terms of warmth, session duration, and comfort, so the choice depends on your goals.
3. EMF and Safety
When researching infrared saunas, you will often see terms like “low-EMF” or “near-zero-EMF.” EMF stands for electromagnetic field, which is emitted by many electrical devices.
Modern infrared saunas are designed so EMF levels remain low and typically fall well within international safety guidelines when properly manufactured and installed.
Many companies reduce EMF exposure through shielding, improved wiring, and better heater design. In practice, EMF exposure from a quality sauna is often similar to or lower than many common household appliances.
For most users, EMF from properly built infrared saunas is unlikely to pose significant risk, though choosing certified equipment and proper installation is recommended.
The most important safety practices remain simple:
-
Choose certified equipment
-
Follow recommended session times
-
Stay hydrated
-
Consult a doctor if you have medical conditions
4. Size and Capacity Guide
Infrared saunas are usually categorized by how many people can sit comfortably.
A 2-person sauna is ideal for apartments, small homes, or personal use. It requires less power and space.
A 4-person sauna works well for families or shared wellness rooms.
A 6-person sauna is usually installed in dedicated home gyms, studios, or spa-style wellness rooms.
When planning size, consider not just seating capacity but also ceiling height, ventilation space, door swing area, and installation access.
Many buyers regret choosing too small a sauna, especially if they expect guests or shared use.
5. Installation Requirements
One advantage of infrared saunas is that they are easier to install than traditional saunas.
Most home units require only a standard electrical connection, while larger models may need a dedicated circuit. Always confirm electrical requirements before purchase.
Ventilation is helpful but usually minimal compared to traditional saunas. Good airflow around the sauna improves comfort and longevity.
You should also consider:
-
Floor strength
-
Room humidity
-
Door clearance
-
Distance from walls
Professional guidance can help avoid common installation issues.
6. Indoor vs Outdoor Use
Infrared saunas are usually installed indoors because electronics and heaters must be protected from weather. Outdoor infrared saunas are available but require proper insulation, roofing, and weather protection.
If you plan an outdoor installation, make sure the sauna is rated for exterior use.
Indoor saunas are easier to maintain and typically last longer.
7. Infrared vs Traditional Sauna
Many buyers compare infrared and traditional saunas before deciding.
Traditional saunas heat the air using stones or heaters, creating intense high-temperature dry heat. Infrared saunas heat the body directly at lower temperatures.
Some people prefer traditional saunas for cultural reasons or high-heat experiences. Others prefer infrared saunas for comfort and convenience.
Neither is “better” in every case. The right choice depends on your space, preferences, and wellness routine.
Many homes even install both types.
