Both red light therapy and infrared saunas are popular recovery tools, but they work very differently. Here’s a detailed comparison.
How They Work
Red Light Therapy
- Uses specific wavelengths of light (630-850nm)
- Light is absorbed by mitochondria
- Boosts cellular energy (ATP) production
- Non-thermal — no heat involved
- Works at the cellular level
Infrared Sauna
- Uses infrared radiation to heat the body
- Raises core body temperature
- Induces sweating and cardiovascular response
- Thermal effect — heat is the primary mechanism
- Works through systemic heating
