Is Red Light Therapy Really Effective

What is red light and red light therapy?

Red light is taken from sunlight, it is red visible light with wavelength of 600~700nm, and the central wavelength is 650nm, accounting for only 3% of the sunlight. There is no ultraviolet and burning infrared, the red light will not harm the skin and has no side effects. Besides, the red light therapeutic instrument is a cold light source, can be used for early intervention treatment on the wound surface.

Red light therapy is a phototherapy method with photochemical action as the therapeutic mechanism. The red light therapeutic instrument filters most of the infrared light through the physical method, removes the thermal effect, and retains the red light in the 600~700nm band. Red light therapy has the characteristics of high output power, deep tissue penetration, and convenient operation.

Red light can penetrate the skin, which is called the "optical window" of the skin and the "light of life" in medicine. Red light is a safe and effective physiotherapy in modern fast-paced life.

Role of red light

1. Increased cell energy supply: the largest absorber of red light emitted by red light is mitochondria, which increases the catalase activity of mitochondria, thus leading to an increase in ATP production. Experiments have proved that red electromagnetic wave can increase the ATP of Hela cells by 190%.

2. Free radical scavenging: Modern medical research has confirmed that the aging and function decline of the human body are closely related to the increase of free radicals in the body, and a large number of free radicals will be produced when many diseases, such as cerebrovascular accidents, coronary heart disease and other diseases occur. Red light can significantly enhance the activity of superoxide dismutase (SOD), help to eliminate free radicals in patients, avoid lipid peroxidation etc. functional damage, and is conducive to disease treatment.

3. Promote wound healing: red light promotes the proliferation of fibroblasts and endothelial cells, increases cell metabolism, and promotes cell synthesis, thus accelerating wound healing.

4. Increase of blood oxygen carrying capacity: red light can improve the binding capacity of blood Hb and O2, and significantly increase the blood oxygen carrying capacity (7.6%).

5. Improve human microcirculation disorder: the occurrence and development of most cardio-cerebrovascular diseases are related to hemorheology disorders. Red light can improve the human microcirculation system by increasing the deformability and fluidity of red blood cells, improving the aggregation of platelets, regulating the lipoprotein spectrum, reducing blood lipids, reducing blood viscosity, and improving blood rheology disorders.

6. Increase of endogenous enkephalin: experiments show that red light can relax nervous tension, relieve brain pressure and eliminate chronic fatigue.

What are the effects of red light therapy?

1. It can effectively inhibit inflammation and relieve pain: red light irradiation can control staphylococcal infectious inflammation. Its main mechanism is to stimulate the body's defense ability, show the strengthening of immune function, promote and accelerate the production of tissue active substances and the metabolism of pain substances, and eliminate inflammation as soon as possible.

2. Red light irradiation can also effectively inhibit nerve excitation, relax muscles, make painful parts fully aerobic metabolism, block the vicious cycle of pain, and achieve the purpose of relieving muscle spasm, relieving pain and improving pain.

3. It can accelerate wound healing: the biological stimulation of red light can effectively promote the proliferation of tissue fibroblasts and endothelial cells, increase cell metabolism, promote cell synthesis, promote granulation tissue growth, and achieve rapid wound healing.

There is a research shows that 630-650nm red light wave can act on 10-15mm deep tissue, realize muscle vitality, and double maintenance the human body parts, such as neck, waist and abdomen etc. Pangao neck massager S20 and waist massager PG-2645L has function of red light to relieve muscle fatigued and pain. Apply to household massage and help you stay away from sub-health.
