What Is Red Light Therapy?

Red light therapy, also known as low-level light therapy or photobiomodulation, has gained popularity in recent years as a non-invasive, drug-free treatment for a variety of conditions. This therapy involves exposure to red light wavelengths, which penetrate the skin to promote cellular repair and regeneration. While red light therapy can benefit people of all ages, it's particularly beneficial for seniors and older adults.

Red light therapy works by triggering a cellular response in the body. The red light stimulates the mitochondria, which are the energy centers of cells, to produce more ATP (adenosine triphosphate), the molecule that provides energy to cells. This increased production of ATP helps to improve cellular function and repair, leading to a range of benefits for the body.

#1

Skin

One of the main benefits of red light therapy is improved skin health. As we age, our skin loses elasticity and collagen, leading to wrinkles, fine lines, and sagging. Red light therapy can help to promote collagen production, leading to smoother, firmer skin. Additionally, red light therapy can help to reduce the appearance of age spots, sun damage, and other skin discoloration.  A study published in Photomedicine and Laser Surgery found that red light therapy could improve skin health in older adults. The study involved participants aged 50 to 80 who underwent red light therapy for 12 weeks. The results showed that the therapy led to improvements in skin elasticity, firmness, and texture.

Joints

Another benefit of red light therapy is improved joint health. Older adults are more prone to conditions like arthritis, which can cause joint pain and stiffness. By increasing blood flow, red light therapy can help to reduce inflammation in the joints, which can lead to improved mobility and reduced pain. The Journal of Clinical Medicine published a study which concluded that red light therapy could help reduce inflammation and pain in older adults with knee osteoarthritis. The study involved participants aged 65 to 83 who underwent red light therapy for six weeks. The results showed that the therapy led to a reduction in knee pain and improved knee function.

Cognitive

As we age, our cognitive function can decline, possibly leading to memory loss and other cognitive impairments. Red light therapy has been shown to promote neuroplasticity, or the brain's ability to adapt and change, leading to improved cognitive function. A study published in the Journal of Gerontology: Biological Sciences found that red light therapy could help  improve cognitive function in older adults. The study involved participants aged 55 to 80 who underwent red light therapy for three months. The results showed that the therapy led to improvements in memory and executive function.
