Red Light Therapy Benefits And Applications

(7) Regulate immune function

The role of red light
Red light irradiation is to filter most of the red light, mainly in the red light band, and its biological function is mainly photochemical. Instead of heat. According to foreign scholars, mitochondria have the largest absorption in the red light region. After red light is irradiated, the catalase activity of mitochondria can be increased. This can increase cell metabolism, increase glycogen content, increase protein synthesis and increase the decomposition of adenosine triphosphate, so it can promote cell synthesis, can promote the healing of wounds and ulcers, promote hair growth, promote fracture healing, and accelerate damaged nerves Regeneration also increases the phagocytosis of white blood cells, so it can be used clinically to treat many diseases.

Treatment range
1. Anti-inflammatory and analgesic have curative effects on some acute

subacute and chronic inflammations. Because it can increase the phagocytosis of white blood cells, it also improves the body's immune function and increases the body's defense function. In addition, in the early and middle stages of inflammation, the content of serotonin in local tissues increases. This serotonin can cause pain in the body. After being irradiated with red light, the content of serotonin can be reduced, thus playing an analgesic effect. Indications: Furuncle, carbuncle, erysipelas, eczema, cervical erosion, vulvar itching, chronic pelvic inflammatory disease, postpartum infection, dysmenorrhea, phlebitis, frostbite, cholecystitis, prostatitis, periarthritis, paronychia, brachial plexus and its Peripheral nerve injury, anal itching, chronic cryptitis, anal fissure, cystic hyperplasia of the breast, acute mastitis; costochondritis, cervical spondylosis; pediatric pneumonia, infant diarrhea, rheumatoid arthritis, costal rheumatoid arthritis, bone Arthritis, ulcerative structural inflammation, bronchial asthma, jaw arthritis, laryngitis, nasal vestibulitis and other diseases.
2. Promote the healing of wounds and ulcers.

The stimulation of red light can increase the number of fibrocytes and increase the formation of glial cells, so it can strengthen cell regeneration and promote the growth of granulation tissue. For example, X-ray treatment has good curative effect on refractory ulcers, malnutrition ulcers caused by phlebitis, bedsores caused by long-term bed rest, and poor healing of surgical wounds.
3. Promote hair growth and accelerate callus healing.

Red light stimulation of nerve injury can accelerate hair growth. Therefore, it can be used to treat alopecia areata, seborrheic alopecia and other diseases. Red light irradiation can promote callus growth and fracture healing. Because red light can stimulate the growth of injured peripheral nerve axons, accelerate the formation of nerve myelination, and accelerate the reinnervation of skeletal muscles, it can treat peripheral nerve injury.
4. Photosensitive treatment

Use red light with photosensitive drugs to treat malignant tumors. It has certain characteristics, such as preventing tumor cells from splashing, and less damage to normal cells. Due to the high price of the laser or the low output power, it affects the development of this photosensitive treatment; and red light can replace this deficiency. . Because its output can reach the watt level, and the price is only 1/3 to 1/5 of the laser price. So it can be used to treat cancer. 48-72 hours after injection of hematoporphyrin derivatives, irradiate the tumor with red light (power density of 200mw/cm2). After 20-30 minutes, the tumor tissue will appear edema and congestion. After 24 hours, the tumor will become black and necrotic, one week Later, black scabs formed. After the black scabs fell off, the tumor tissue disappeared. This method can be used to treat skin cancer; oral cancer, cervical cancer and other cancers.

Features:
1. The output power is large, the penetration depth is deep (10-15mm), and the spot can be directly enlarged, and its power density can also meet the requirements of treatment. For a large area of diseased parts, it can be included in the spot range at a time, so that Uniform irradiation and shorten treatment time.
2. In addition to the treatment of body surface diseases, intracavitary treatment can also be carried out. Intracavitary treatment can be performed by irradiating the spot with a light guide system, such as treating chronic pharyngitis, cervicitis, chronic prostatitis and ulcerative colitis. Laser therapy has not been short for hair loss treatment, and it has achieved good results. It is a physical treatment that uses the thermal and photochemical effects of laser on human skin to treat abnormal hair loss on the head. The principle is to use soft laser light (red light and far red light) to penetrate into the subscalp cells (hair roots and hairs). Milk ball) the deepest layer, to accelerate blood circulation, regulate endocrine and improve hair quality. In addition to inhibiting shedding, it can also make hair grow back. Laser irradiation can increase skin temperature and strengthen local blood circulation, reduce the sensitivity of nerve endings, reduce scalp itching and local pain, and have a better control effect on oil secretion. Red light combined with topical medicine to treat eczema.
The main output of the red light therapy device is the red light band. Its biological effect is mainly photochemical effect, not thermal effect. After red light irradiation, the catalase activity of mitochondria can be increased. At the same time, it can increase the phagocytosis of white blood cells and improve the immune function of the body. The stimulation of red light can increase the number of fibroblasts, increase the formation of collagen, increase cell metabolism, and increase glycogen. Therefore, it can promote cell synthesis, promote the healing of wounds and ulcers, and has no side effects on the human body.
The application of the red light therapeutic apparatus in combination with external drugs to treat eczema has high curative effect, short treatment course, and can reduce the side effects of drugs, which is easy for patients to accept.

Observation on the effect of high-energy narrow-band red light irradiation on facial seborrheic dermatitis
Objective: To observe the clinical effect of high-energy narrow-band red light irradiation on facial seborrheic dermatitis. Methods: 48 patients were randomly divided into treatment group and control group. The treatment group was irradiated with red light, the treatment wavelength was 633nm, the energy density was 126J/cm2, and each time was irradiated for 20min, once every 3 to 4 days, and the curative effect was observed after 4 weeks; the control group was externally treated with 5% sulfur cream, twice a day , Observe the effect after 4 weeks. Results: The effective rate of the red light treatment group was 87.50%, and the effective rate of the control group was 37.50%. The difference between the two groups was significant (P0.05). Conclusion: Red light irradiation is effective, safe and has no obvious side effects in the treatment of facial seborrheic dermatitis. It is worthy of clinical application.
