Red Light Therapy vs. Infrared Sauna: What's the Difference?
Red light therapy (RLT) and infrared sauna are both popular wellness technologies that use light-based energy. They work differently and are often confused. Here is a side-by-side comparison to help you choose, or use both.
The Core Difference
| Feature | Red Light Therapy | Infrared Sauna |
|---|---|---|
| Primary wavelength | 660nm (red) + 850nm (NIR) | Far infrared |
| How it works | Low-level light exposure (photobiomodulation) | Radiant heat |
| Heat | Not designed to heat the body | Designed to warm the body |
| Session length | 10 to 20 minutes | 20 to 45 minutes |
| Typical use | Face or targeted body areas | Whole-body warmth |
| FSA/HSA eligible? | Yes (AWA devices) | Yes (AWA HL300) |
Red Light Therapy: How It Is Used
Red light therapy uses low-level light energy, not heat. Devices come in several formats:
- Face masks: worn on the face
- Panels: cover larger areas of the body
- Handheld and wrap devices: used on smaller or targeted areas
Best AWA devices: FX300 Panel, FX500 Panel, LX300 Face Mask
Infrared Sauna: How It Is Used
Infrared saunas use far-infrared wavelengths to warm the body. A portable sauna blanket offers a whole-body warm-up at home, with sessions commonly lasting 20 to 45 minutes. Follow the instructions for your device and stay hydrated.
Best AWA device: HL300 Portable Far Infrared Sauna Blanket
Can You Use Both Together?
Some people use both in the same routine. One common order:
- Red light therapy session (10 to 20 min)
- Infrared sauna session (20 to 30 min)
- Cool down and hydrate
Follow the instructions for each device, and check with a healthcare provider if you have a medical condition.
Both Are FSA & HSA Eligible at AWA
AWA red light therapy panels, face masks, and the HL300 infrared sauna blanket are FSA and HSA eligible. Eligibility depends on your plan administrator.
