Red light therapy, also known as low - level light therapy (LLLT), is a non - invasive treatment that uses red or near - infrared light to improve various aspects of health.

Red light therapy employs light - emitting diodes (LEDs) or lasers to emit red light with wavelengths typically ranging from 600 to 950 nanometers. This light penetrates the skin at different depths depending on the wavelength. Near - infrared light penetrates deeper into the body compared to red light.

Cellular Level Interaction:

• Mitochondria, often referred to as the "powerhouses" of cells, absorb the red or near - infrared light.
• When weak mitochondria in cells are exposed to red light with specific wavelengths (such as 880nm and 660nm as shown in the diagram), they can become more active.

ATP Production:

• The activation of mitochondria leads to an increase in adenosine triphosphate (ATP) production. ATP is the primary energy currency of cells, and higher ATP levels mean cells have more energy to perform their functions.

Protein Synthesis:

• Red light therapy can also stimulate protein synthesis. The enhanced production of proteins helps in cell repair, growth, and regeneration.

Other Benefits:

• On a broader scale, red light therapy can have various other positive effects such as reducing inflammation, promoting wound healing, improving skin health by increasing collagen production, and potentially enhancing muscle recovery and performanc
