Infrared Sauna vs. Infrared Light Therapy — What Is the Difference?

Both infrared sauna and infrared light therapy use infrared energy. They are offered at many of the same wellness centers. And people often ask if they are really that different — or whether they are essentially the same thing with different marketing.

They are genuinely different. They use different wavelengths, work through different mechanisms, and are useful for different goals. Here is a clear breakdown.

The Basic Difference

An infrared sauna is a heat experience. The infrared panels heat the air and your body to produce sweat. The goal is warmth, relaxation, and the physical effects of raising your core temperature — loosened muscles, increased circulation from the heat response, and the general restorative feeling that comes from a good sweat.

Infrared light therapy — specifically near-infrared — is not primarily about heat. It uses specific wavelengths of near-infrared light that penetrate below the skin surface and are absorbed at a cellular level. The goal is to support the body's energy production and recovery processes, not to produce significant heat or sweat.

Wavelengths — Why It Matters

Infrared energy spans a range. Saunas typically use far-infrared wavelengths, which are longer and are absorbed primarily at the skin surface — producing the warmth you feel.

Near-infrared wavelengths are shorter and penetrate deeper. They are what devices like the NovoTHOR bed use. The body's tissues absorb this light differently than heat, and the mechanism of action is related to how cells process and use energy — not temperature elevation.

The practical takeaway: one is a heat therapy, the other is a light therapy. They happen to both involve the word "infrared" because they both use parts of the infrared spectrum — just different parts, with different effects.

What Each One Is Good For

Infrared Sauna

• Relaxation and stress relief
• Loosening muscles before or after physical activity
• A comfortable, low-temperature sweat session
• Wind-down and recovery at the end of a long day or week
• People who want the sauna experience without extreme heat

Infrared Light Therapy (NovoTHOR)

• Supporting recovery at a deeper level without heat
• Post-workout muscle and tissue recovery
• People dealing with soreness, fatigue, or inflammation
• Athletes who want efficient full-body light sessions
• Those who want recovery support without working up a sweat

The Session Experience

In an infrared sauna, you sit or lie in an enclosed wooden cabin. The temperature climbs — usually to somewhere between 120 and 150 degrees Fahrenheit, which is noticeably lower than a traditional steam sauna. You will sweat. Sessions typically run 30 to 45 minutes. It is a warm, quiet, private experience.

In the NovoTHOR near-infrared bed, you lie inside the bed fully clothed (or in light clothing) while the near-infrared panels work around you. It is not hot in the same way a sauna is — you may feel gentle warmth, but you are not going to be sweating. A full-body session runs around 12 minutes.

Can You Do Both?

Yes, and many people do. They serve different purposes and complement each other well. A common combination is to do a NovoTHOR session for recovery support and an infrared sauna session for relaxation and the heat experience — either on the same visit or on different days, depending on your goals and schedule.

If you are unsure where to start, the simplest approach is to think about what you are actually trying to accomplish: if you want to sweat and relax, start with the sauna. If you are focused on post-workout recovery or managing soreness, start with the infrared light therapy.
