Learn how light therapy effectively relieves muscular pain by reducing inflammation, enhancing blood flow, and accelerating tissue repair.
Muscle pain is hard to avoid. With more than 600 muscles in the human body, discomfort can arise easily, and about one in three Americans experiences it each year.
Musculoskeletal pain affects roughly 116 million people in the United States, often leading to poor productivity, missed work or school, fatigue, and reduced motivation.
Current treatments include non-steroidal anti-inflammatory drugs, steroid injections, pain medications, and surgery, each carrying its own risk profile.
Low-Level Laser (Light) Therapy (LLLT) offers a non-invasive, low-risk, and potentially cost-effective option. Used in medicine for over four decades, LLLT may reduce inflammation and edema and can support healing in various musculoskeletal conditions. Because muscle pain has many causes, athletes, fitness enthusiasts, medical patients, and older adults might all consider this approach.
Red to near-infrared light (660 nm–905 nm) is applied to the skin. These wavelengths can penetrate soft and hard tissues, and clinical studies suggest beneficial effects on pain, inflammation, and tissue repair. A single session may last 30–120 seconds or longer, repeated weekly depending on severity, and treatment courses can extend for weeks or months based on tissue response.
Reported outcomes include reduced inflammation, pain relief, and accelerated tissue regeneration.
Many acute orthopedic problems—strains, sprains, muscular back pain, frozen shoulder, neck and back pain—may respond to LLLT.
Infra-red light can ease discomfort, promote relaxation, and soothe muscles. Laboratory work indicates that LLLT may enhance fibroblast, keratinocyte, endothelial-cell, and lymphocyte multiplication, supporting the inflammatory and repair phases of healing.
LLLT might also encourage neovascularization, angiogenesis, and collagen synthesis, aiding acute and chronic wound healing. LED sessions have been studied for effects on skin, nerves, tendons, cartilage, and bone. Low-intensity light can stimulate mitochondria and may improve mitochondrial membrane potential.
Peripheral nociceptor endings—thinly myelinated A-delta and unmyelinated C fibers—lie superficially within the epidermis, allowing red-to-near-infra-red photons to reach them easily.

As chronic pain becomes more common worldwide, validating cost-effective, low-risk ways to manage it—so people can stay active and productive—is increasingly important. Light therapy is being studied for easing muscle discomfort; small trials suggest it may improve muscular endurance and lessen soreness, joint pain, and inflammation.
Light therapy from LED masks is one option being explored.
