How can red light help relax stiffness?

According to research by foreign scholars, red light and near-infrared rays have the deepest penetration depth to human skin. According to research by YY. Huang and many scholars, when 600~900nm red light and near-infrared rays are irradiated, the mitochondrial chromophore in biological skin cells will absorb photons, trigger electron transmission, and release the human body’s smallest energy unit ATP (Adenosine triphosphate) and NO (nitric oxide) to help increase blood flow and ROS (reactive oxygen) content, guided by different physiological signals, to help the health of biomolecules, while maintaining blood circulation, to achieve positive help for organisms and the human body.

Higher-band infrared rays cannot be seen by the naked eye, while the visible red light has a wavelength between 620-770nm. Although the penetration depth of the skin is not as deep as infrared rays, research has found that red light will not be absorbed by water molecules in tissues and It generates heat, and the absorption of its mitochondria is equivalent to that of infrared rays. It can be called light that can be absorbed by organisms and the human body. It helps maintain the microcirculation of the human body, and it does not store heat like near-infrared rays. If you use it for an extended period of time, you may be worried about the possibility of burns. Light, red light, etc. can be absorbed by the human body or organisms through mitochondrial cytochrome C oxidase (Cytochrome C Oxidase), maintain health factors such as ATP energy, and help organisms and human health maintenance (Begum et al., 2013).

Why is it hard?

The energy source of the cell is located in the mitochondria, from which cellular energy or adenosine triphosphate (ATP) is produced. When human tissues are under stress or ischemia, mitochondria themselves produce mitochondrial nitric acid (MtNO) to compete with oxygen, combine with cytochrome C oxidase (CCO), and reduce ATP synthesis.

How does Low Level Lighting (LLLT) help positively?

When these tired cells are exposed to low-level light (LLLT), it affects the human body in several stages

1. Light energy is absorbed by cytochrome C oxidase, causing multiple downstream effects;
2. Release nitric oxide (NO);
3. ATP increase;

These biochemical intermediates help the internal operation of biomolecules to be healthy and normal, help maintain blood circulation, and provide health care.

So a simple description is,Through the irradiation of LLLT red light, the human body inhibits the combination of cytochrome C oxidase and nitric oxide (NO), and replaces it with oxygen to release nitric oxide (NO), thereby maintaining healthy molecules such as ATP and oxygen (ROS).
