What Is Red Light Therapy?

In our last post, we shared a video on how dangerous infrared lasers can be for your eyesight, especially those that are invisible. And while infrared lasers have provided many benefits in many different aspects of life, we still have a lot to learn about their effects on humans. 

One thing we do know is that some types of lasers and light can be used on humans and they come with incredible health benefits.

Many of you may have heard of Red Light Therapy (RLT) a.k.a. Cold Laser Therapy, Soft Laser Therapy, Biostimulation, and Photonic Stimulation, a controversial type of therapy that produces red low-level wavelengths of light to help treat certain skin conditions. It is used both for cosmetic skin conditions as well as medical skin conditions such as slow-healing wounds.

In the early 1990s, scientists found that red light therapy was a great way to grow plants in space. They discovered that the intense light from the red diodes not only promoted growth in plants but also photosynthesis in the cells of plants. 

Once scientists saw the benefits this light had on growing plants they decided to study what it could do in the medical field to possibly increase the energy within human cells. They were hoping it might be a sure-fire way to treat conditions such as Muscle Atrophy and those with bone density issues. They have since found it to be useful in a form of therapy known as Photodynamic Therapy where it is used as an acting agent in medications which helps to photosynthesize them.

Today Red Light Therapy is used in both cosmetic and medical settings. Its cosmetic uses include: correcting skin issues such as stretch marks, wrinkles, and pigmentation. In medical settings it is used for the relief of psoriasis, to help with the side effects of chemotherapy, and to help slow-healing wounds. And while the effects of RLT seem to look promising up to this point, there is still a lot to be learned, researched, and experimented with.
