But what exactly is red light therapy, and how does it work? Red light therapy, also known as photobiomodulation, is a non-invasive treatment that uses specific wavelengths of red and near-infrared light to stimulate cellular activity and promote healing. It’s gaining popularity for its potential benefits in treating various conditions, including skin rejuvenation, wound healing, and pain management. The science behind red light therapy is rooted in the concept of photobiomodulation, which suggests that light can be used to modulate cellular processes. This modulation occurs at the cellular level, affecting the mitochondria, the powerhouses of the cells. Mitochondria are responsible for producing energy for the cells.

This finding suggests that red light therapy could be a valuable tool for astronauts in space, potentially aiding in wound healing, tissue regeneration, and even bone density. Dr. Hammer further explains that red light therapy can be used to stimulate the production of collagen, a protein that plays a crucial role in wound healing and tissue regeneration. Collagen is essential for the growth and repair of tissues, and its production is often hampered by the microgravity environment of space.

“They’ve been using red light therapy for decades to treat skin conditions like acne, rosacea, and psoriasis.”

This explanation is supported by numerous scientific studies that have shown the effectiveness of red light therapy in treating various skin conditions. For example, a study published in the Journal of Investigative Dermatology found that red light therapy significantly reduced the severity of acne lesions. Another study published in the* The Lancet* found that red light therapy was effective in treating rosacea. These studies demonstrate the efficacy of red light therapy in targeting specific skin conditions. Beyond skin conditions, red light therapy has also been shown to have positive effects on other areas of the body.
