The human body is made up of trillions of cells, each containing structures called mitochondria. Often referred to as the “powerhouses” of the cell, mitochondria are responsible for producing the energy required for cells to function, repair, and regenerate. RLT uses specific wavelengths of red and near-infrared light that are absorbed by the mitochondria. One of the key molecules involved in this process is an enzyme called cytochrome c oxidase, which plays an important role in cellular energy production.

Research suggests that red and near-infrared light may help optimise the function of cytochrome c oxidase, supporting the mitochondria’s ability to produce adenosine triphosphate (ATP) — the primary energy currency of the cell.

As cellular energy production increases, a range of beneficial biological responses may occur, including: increased ATP (cellular energy) production, improved cellular oxygen utilisation, enhanced circulation and blood flow, support for tissue repair and regeneration, reduced oxidative stress, modulation of inflammation, improved recovery following physical activity and support for healthy cellular function.

By supporting mitochondrial function, red light therapy aims to enhance the body’s natural processes of repair, recovery, and regeneration. This is why it has become increasingly popular for applications such as skin health, muscle recovery, joint comfort, hair growth, wound healing, and general wellness.

While research into red and near-infrared light therapy is growing, individual responses vary, and red light therapy should not be considered a replacement for medical diagnosis, treatment, or professional healthcare advice.
