Brief History of Photobiomodulation
Light therapy could be said to be hundreds, if not thousands of years old. There is evidence of ancient civilisations using and recommending sun exposure for therapeutic use. Modern ‘Light therapy’ or as it is now known ‘Photobiomodulation therapy’ goes back to the 1960’s to a Hungarian University where Endre Mester wanted to test if laser radiation would cause cancer in mice. Endre shaved the dorsal hair from the mice in his experiment and divided the mice into two groups. One group was given laser therapy using a low powered Ruby laser with the wave length of 694nm and the other group wasn't. As it turned out, the group that was given laser treatment did not get cancer. In fact the hair grew back faster in the group that had the laser treatment than in the mice with no treatment. This is said to have been the first ‘bio stimulation’ effect recorded.
Since that time, low power laser also known as Low Level Laser Therapy (or LLLT) has gone on to be a popular method of therapy used across a wide range of professions. It started as part of physio therapy and now is now widely used by Chiropractors, physiotherapists, race horse trainers, vets, dentists and other professionals as well as home users.
Many people have access to and use LLLT or Photobiomodulation therapy. In recent years, much research has turned to LED light therapy. It is much cheaper and safer to use for the home user. LED lights in the red and infra-red wave lengths are proving to be very effective in stimulating healing of injuries, reducing pain and inflammation that arise from various sources. The latest trend in photobiomodulation is the use of intra nasal LED and low level lasers .
Lu Lim, the founder of VieLight has some impressive clinical data and some on-going studies on Intra nasal and cranial use of light for the improvement of cognitive conditions. The world of Light and Laser therapy is snowballing and we can gain benefit from simply clipping a small LED light into the nose once per day for around 20 minutes. Although it may look a little odd, it is very convenient to use this way. There are a vast amount of blood vessels in the nasal cavity which allows the light or laser shone into that area to directly affect enough blood cells in the time span to have a great effect. Lu Lim suggests that this is as effective as intravenous light therapy that has been popular in Russia for many years, and far less expensive and invasive.
