Red light therapy works through a process called photobiomodulation. Certain wavelengths of light are absorbed by components inside the cell, which may influence how the cell produces and uses energy.
Researchers have proposed that red and near-infrared light may be absorbed by cytochrome c oxidase, ett enzym i mitokondriernas andningskedja. This interaction has been studied for its potential influence on cellular energy metabolism, inflammatorisk signalering, och cirkulation.
This matters for usage because light therapy follows a dose-response relationship. För lite exponering kan inte ge någon effekt, while excessive exposure provides no additional benefit and can unnecessarily warm the skin.
Det är därför rätt sessionslängd, konsistens, and skin exposure are more important than simply staying under the lights for as long as possible.
