Before selecting a duration, review the variables that shape exposure. A responsible operator should be able to explain each of the following:
- Te irirangi: the optical power delivered over a defined area. Higher irradiance can reach a target dose in less time, but it does not justify guessing.
- Wavelength mix: red and near-infrared settings may be intended for different tissue depths or goals.
- Distance and position: even small changes can alter the light reaching the body, especially in systems with directional panels.
- Te waahi maimoatanga: a full-body red light therapy bed exposes more skin than a small panel, so the overall experience and heat load may differ.
- Pulse or continuous mode: some systems use programmed cycles that cannot be compared directly with a continuous-light session.
- Personal response: tairongo kiri, medication use, eye health, and medical history may affect whether a protocol is appropriate.
Ask for the red light therapy device’s technical specifications and the intended program rather than relying on the phrases “high power” or “professional strength.” Clear documentation helps prevent overexposure and makes the session easier to reproduce.
