Low Level Light Therapy (LLLT) or Photobiomodulation Facts
History of LLLT
Low level laser therapy (LLLT), also known as photobiomodulation, came into being in its modern form soon after the invention of the ruby laser in 1960, and the helium–neon (HeNe) laser in 1961. In 1967, Endre Mester, working at Semmelweis University in Budapest, Hungary, noticed that applying laser light to the backs of shaven mice could induce the shaved hair to grow back more quickly than in unshaved mice.
What is LLLT?
LLLT involves exposing cells or tissue to low levels of red and near infrared (NIR) light, and is referred to as “low level” because of its use of light at energy densities that are low compared to other forms of laser therapy that are used for cutting, and creating heat.
CELLULAR AND TISSULAR MECHANISMS OF LLLT
From observations, LLLT has a wide range of effects at the molecular, cellular, and tissular levels. Evidence here has shown support that LLLT acts on the mitochondria to increase adenosine triphosphate (ATP) production, which is where energy comes from.
How Often should I use Low Level Light Therapy?
LLLT is characterized by a biphasic dose response: lower doses of light are often more beneficial than high doses. 6 times in the first month for 10-15 min is recommended. And once per week for 15 min is considered maintenance level.
Should I do Cryotherapy with LLLT?
Yes. Cryotherapy works with the blood to increase oxygen and glucose in the blood stream it will only assist the LLLT by adding oxygen and glucose to the blood which is the fuel for the cells mitochondria that produces ATP.
Are there studies on LLLT and is it safe?
Yes. More studies have been done on LLLT than cryotherapy and it has been found to have no side effects. See studies here.
What is a summary of LLLT?
Low Level Light Therapy does one thing well and that is reduce oxidative stress. Oxidative stress (aging) is accepted as the underlying trigger for most diseases and degenerative conditions. It is also a component in the inflammatory phase of acute and chronic injuries.
