Red light therapy dose explained

Dose is one reason red light therapy cannot be reduced to a single power specification. The amount of energy delivered depends on output and exposure time, along with practical factors such as distance and treatment area.

Why this matters when reading studies

A study result belongs to a specific protocol. Changing the wavelength, dose, distance, schedule, or target can change the treatment being discussed. That is why we avoid turning one study into a promise about every red light device.
