The term photobiomodulation (PBM) therapy refers to the use of non-ionising irradiation, frequently in the red or near-infrared light spectrum, to trigger changes in cellular structures receptive to photons. Typically, the light energy is absorbed by the mitochondria (the power house of the cell) and converted to ATP. In the process, mild oxidants and nitric oxide (a signalling molecule) are released triggering a cascade of processes that inhibit inflammation and promote healing, regeneration, and rejuvenation of tissue. This has been found to be particularly beneficial for tissue that has either been injured, inflamed, or is degenerating as a result of age, stress, lifestyle or a combination of these factors.
The human brain is the most complex organ in the human body and as such is, unsurprisingly, most susceptible to damage. Stressful work life, poor sleep and lack of sufficient relaxation opportunities are among the factors that trigger cell aging, inflammation, reduced energy production and inefficient connectivity within brain cells and networks.
Photobiomodulation offers us a potential non-invasive direct route to improving cell metabolism and vasodilation, and to supporting cell vitality and longevity.
