The Red Light therapy has different names like
- Photobiomodulation (PBM) Therapy,
- Lower Level Laser (Light) Therapy (LLLT),
- Soft-Laser Therapy,
- Cold-Laser Therapy,
- Bio-stimulation Therapy,
- Photonic-Stimulation Therapy,
- Lower-Power (LP) Laser Therapy (LPLT).
These names are after the light and method used for this therapy.
Process or treatment
Red Light treatment, the human body, or a particular part of the body made to expose to the Red Light. The Redlight penetrates through the skin and reaches the cell’s power generator called mitochondria. It soaks in that light, which helps to increase its energy to function faster. Thus these mitochondria produce more ATP (adenosine triphosphate), which carries energy molecules. Therefore with these more quickly creating ATPs’s the cell in the body can regenerate and repair themselves at a faster rate than the standard time, leading to more rapid production of cells.
Red Light therapy is a natural one with no pain and no invasive. Red Light is harmless to skin. It doesn’t cause any damage to any cells, tissues, or muscles. This light penetrates up to 5 millimeters of skin without stimulating the skin.
Benefits of Red Light
Infrared (low level) light is helpful in human body cells and tissues to regenerate and repair them, and also low-level infraRed Light also improves the circulation of oxygen-rich blood in the body.
In a study, some particular wavelength in infrared is useful for the human body. Like 830nmand 633nm is the specific wavelength give benefits to the human body, i.e., is mainly on skin cell and muscles.
