What are the benefits of red light in the solar spectrum?

Red light is considered to be the spectrum of life, because red light waves can easily penetrate the human body and reach germs, anti-inflammatory, sterilizing, improving protein solidification in the affected area, promoting blood circulation, enhancing immunity and metabolism, etc.

 

After experiencing COVID-19, people are gradually realizing the benefits of basking in the sun. Some studies show that people today receive almost 1,000 times less light than their ancestors received. Our ancestors bathed in the sun all day and then gathered around red bonfires at night. But today, with the widespread use of artificial light sources and the increase in indoor activities, healthy sunlight has been far away from people.

 

Sunlight is the healthiest light. The recognition, understanding, analysis and application of sunlight by human scientists has lasted for thousands of years. The establishment of the wave-particle duality theory has also confirmed the in-depth research of sunlight by human scientists. Light is biologically active and can actually enter cells and affect mitochondrial function. The longer the wavelength of light, the deeper it can penetrate into cells. Light is composed of electromagnetic waves. From this perspective, it makes sense that light can penetrate cells, similar to X-rays and other radiation.

 

Sunlight has a very rich spectrum, and each type of spectrum has its own unique health effects, such as red light for the liver's construction, green light for the balance of the human body, blue light for the calmness of the human body, yellow light for muscle stimulation, purple light for The suppression of pain, the growth of bones by ultraviolet rays, the supply of heat by infrared rays... Human beings are born, evolve, grow and expand under the irradiation of sunlight. Human health has long been closely related to sunlight.

 

In today's artificial light sources, people have paid attention to the adverse effects of blue light and the sterilization and disinfection of ultraviolet light, but the health effects of red light have been too neglected. In our daily lighting, the red light component is seriously missing. This is because the lighting sources used daily are artificial light sources. Currently, they are mainly LED light sources. The spectrum of many light sources is incomplete, not full, and lacks red light components, which leads to the emergence of people who work and live under this light source for a long time. Various symptoms. Actually modern medicine has long proven that red light has a significant impact on human health.

 

Research by Professor He Mingguang and his team from the Sun Yat-sen University Eye Center shows that in myopic children aged 8-13, repeated low-intensity red light therapy can effectively control the progression of myopia in children. As a new alternative therapy, red light therapy has good user acceptance and no functional and structural damage was observed.

 

Research by Professor Pan Jiyang, Director of the Psychiatric Department of the First Affiliated Hospital of Jinan University, and his team shows that a sunny environment has a good effect on the prevention and treatment of depression, and the red light component in the spectrum can effectively control the progression of depression.A 2019 foreign study showed that red and near-infrared light can reverse depression in 60% of participants in just 4 weeks of treatment.

 

Red light can also reverse skin aging.Red light stimulates the production of collagen and elasticity, which can make skin look reverse-aged and help heal the damage that accumulates with age. At the 10th National Laser Biology Academic Conference of the Genetics Society of China, He Yanyan’s team from the State Key Laboratory of Laser Technology at Huazhong University of Science and Technology reported that they used red LEDs with a wavelength of 650 nm to irradiate the human liver cancer cell line HepG2 for different times. The results It shows that using low-dose low-intensity red LED can promote the proliferation of tumor cells, while high-dose low-intensity red LED can inhibit cell growth.In other words, red light has a certain effect in treating liver diseases.

 

Michael Richard Hamblin, a professor at Harvard Medical School in the United States, is an expert in the field of photodynamic therapy. He believes that when our cells are hit by stress, as they are today, nitric oxide can actually bind to CCO and displace oxygen. This ultimately blocks ATP production. Red/Near Infrared spectroscopy can separate NO from the enzyme and allow oxygen to recombine with it, actually enhancing ATP production.

 

Red light is considered to be the spectrum of life, because red light waves can easily penetrate the human body and reach germs, anti-inflammatory, sterilizing, improving protein solidification in the affected area, promoting blood circulation, enhancing immunity and metabolism, etc.In human cells, mitochondria absorb red light the most. After being irradiated by red light, the catalase activity of mitochondria increases, which promotes metabolism, increases glycogen content, increases protein synthesis and increases decomposition of adenosine triphosphate, thus strengthening the cell's metabolism. Regenerates and promotes the healing of wounds and ulcers. At the same time, it also increases the phagocytosis of white blood cells and improves the body's immune function. Therefore, red light plays a very important role in human health.
