Joint health infrared refers to the therapeutic application of light in the infrared spectrum, specifically near-infrared wavelengths, to the articular structures, including cartilage, ligaments, and the synovial membrane, to alleviate pain and promote tissue repair. This non-invasive approach is highly relevant in the hormonal health domain, as chronic inflammation and declining hormone levels, particularly estrogen, can contribute to joint degeneration and arthritic pain. Infrared light provides deep tissue penetration, targeting the cellular pathology underlying musculoskeletal discomfort and supporting long-term mobility.
Origin
The use of infrared radiation for thermal and non-thermal healing has a long history, but the specific, non-thermal, low-level laser and LED applications for joint health evolved from the broader field of photobiomodulation (PBM) in the late 20th century. Research focused on identifying the optimal wavelengths that could penetrate deep enough to reach the knee, hip, or shoulder joints while still eliciting a beneficial cellular response in the chondrocytes and surrounding soft tissues.
Mechanism
The mechanism is two-fold: photobiomodulation and mild thermal effect. The non-thermal effect involves the light photons being absorbed by mitochondrial chromophores in the joint tissue cells, increasing ATP production and modulating inflammatory cytokine release. This enhances cellular repair and reduces local inflammation, which is a major driver of joint pain. Concurrently, the mild thermal effect from the infrared energy can improve local circulation, facilitating the removal of metabolic waste and delivery of oxygen and nutrients essential for tissue regeneration and pain relief.
