Can Red Light Help the Body Heal?

For centuries, sunlight has been associated with health and healing—and we are now learning more about why natural light may be so important. Sunlight contains red and near-infrared wavelengths, the same portions of the light spectrum now being studied therapeutically through photobiomodulation. Researchers have proposed that these naturally occurring wavelengths may contribute to some of the beneficial effects associated with sunlight, while controlled red-light therapy allows them to be delivered in a more targeted way.

Scientists believe red and near-infrared light may work partly by influencing the mitochondria—the structures inside our cells responsible for producing much of the energy they use. Certain wavelengths of light can affect mitochondrial activity and cellular signaling, potentially increasing ATP production and triggering biological responses involved in repair, circulation, and inflammation.

Research on red light is especially promising in several areas. Studies suggest that red and near-infrared light may help reduce pain and inflammation, particularly in some musculoskeletal conditions, while other research points to benefits for tissue repair and wound healing. It has also attracted attention in dermatology, where clinical studies have explored its ability to support skin rejuvenation and hair growth, including in people with androgenetic hair loss.

Whenever possible, healthy exposure to natural sunlight provides red and near-infrared light as part of the full spectrum of light God has placed in our environment. Red-light devices can be useful but should not replace time outdoors—or the other foundations of good health such as nutritious food, movement, and rest. As the research continues to develop, red light appears to have a meaningful place alongside these foundational lifestyle practices.
