Before the advent of electricity, humans interacted with light in its purest forms, limited to sunlight, the glow of a fire, or the flicker of candlelight. These natural sources emit red and near-infrared light, serving as vital nutrients for both mind and body. However, the shift towards modern, indoor-centric lifestyles has resulted in a chronic deficiency of this natural light, depriving us of its beneficial biological effects.
Living under artificial lighting for extended durations can gradually disturb our body’s natural cycles. Light of various qualities and wavelengths prompts distinct biological reactions. Our relationship with light requires a more thoughtful and sophisticated understanding.
Fortunately, individuals can enhance their exposure to beneficial light by acquiring specialized lighting. Four incandescent 250 watt red/infrared bulbs and clamp light fixtures work the best and are inexpensive. They can be purchased at most hardware stores. The expensive LED red/infrared panels utilize only a small number of frequencies compared to incandescent so tend to overstimulate and be less effective overall.
Red or near-infrared light therapy is a safe, non-invasive, and chemical-free method effective for treating various conditions. But what’s the mechanism behind it? The technique, known as ‘photobiomodulation,’ involves the absorption of red/near-infrared light energy by cells. This process boosts mitochondrial ATP (energy) production, improves cell signaling, stimulates the synthesis of growth factors, and reduces oxidative stress.
Mitochondria, often referred to as the cell’s powerhouses, generate ATP, a vital energy currency essential for cellular function and overall health. Studies have shown that cytochrome c oxidase, a mitochondrial enzyme, is activated by near-infrared light photons. This activation boosts ATP production in the mitochondria, leading to the release of signaling molecules. These molecules activate genes that protect the cell, combating cellular degeneration through the repair of damaged mitochondria and the release of antioxidants.
The efficacy of red light therapy is significantly attributed to its strong anti-inflammatory properties, which operate through both local and systemic actions. Research indicates that red light therapy can have a holistic impact on the body, suggesting a systemic response where light applied to one area can favorably affect tissues and organs located far from the site of application.
