2. What Exactly is Light Therapy?

For the last 10.000 years we have absorbed sunlight. This main source of light plays a big role in our health and well-being. This was first discovered and used by the Egyptians, and also practiced by the ancient Greeks, Chinese and Indians.

Light has biological effects: in fact, the body needs light to be healthy. We humans know that our body is a powerhouse that needs fuel to be healthy and functional. So, what you surround yourself with, put into your body and work with on a daily basis impacts you more than you might care to admit. Under these circumstances it is even more important to acknowledge this basic correlation and make it a good one. Too much sunlight can be harmful for us, this is mainly because of its blue light and UV light contents.

All light falls along a spectrum of wavelengths. The biggest part of it is red and near-infrared light though, and this the beneficial light we chose to use in all our Luminousred devices. Red and near-infrared light that falls within the wavelength range of 650-850 nanometers (nm) is seen as extremely beneficial. These wavelengths of light have a biological effect on the body like antibiotics or vitamins and affect the function of our cells.

One key element of our cells is the mitochondria. They are round or oval, we can’t physically see them, but they affect everything we do such as cell signaling, steroid synthesis, cell apoptosis, and cellular energy. Often referred to as the “powerhouses of the cell”, because they facilitate the production of adenosine triphosphate (ATP), usually referred to as the “energy currency of life”.

Light therapy, therefore, is the therapeutic science of utilizing red and near-infrared light wavelengths to assist with the treatment of health conditions and promote general well-being. It’s also often referred to as low level light therapy (LLLT), photobiomodulation (PBM), low-power laser therapy or cold laser therapy.
