Sunlight is the healthiest light. The recognition, understanding, analysis, and application of sunlight by human scientists have a history of thousands of years. The establishment of the "wave particle duality" theory also confirms the in-depth research of human scientists on sunlight. Light has biological activity and can actually enter cells, affecting 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 unique health effects, such as the construction of the liver by red light, the balance of the human body by green light, the calmness of the human body by blue light, the stimulation of muscles by yellow light, the inhibition of pain by purple light, the growth of bones by ultraviolet light, and the supply of heat by infrared light. Humans are born, evolved, grown, and strengthened under the irradiation of sunlight, and human health has long been closely related to sunlight.
In today's artificial light sources, people have noticed the adverse effects of blue light and the sterilization and disinfection effects of ultraviolet light, but the health benefits of red light have been too neglected. In our daily lighting, the red component is severely lacking. This is because the lighting sources used in daily life are artificial light sources, currently mainly LED light sources. Many light sources have incomplete and incomplete spectra, lacking red light components, which leads to various symptoms in people who work and live under such light sources for a long time. In fact, modern medicine has already proven that red light has a significant impact on human health.
According to research conducted by the Eye Center of Sun Yat sen University, repeated low-intensity red light therapy can effectively control the progression of myopia in children aged 8-13. As a new alternative therapy, red light therapy has good user acceptance and no functional or structural damage has been observed.
The research conducted by the director of the Department of Psychiatry at the First Affiliated Hospital of Jinan University 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 study conducted abroad in 2019 showed that red and near-infrared light can reverse depression in 6 out of 10 participants in just 4 weeks of treatment.
Red light also has the effect of reversing skin aging. Red light can stimulate the production of collagen and elasticity, which can make the skin look anti-aging and help heal the accumulated damage with age. In addition, 650 nm red light has been shown to promote hair growth in men with androgenic alopecia. Even foreign studies have shown that both red and near-infrared light therapies are effective in improving male and female fertility. This extraordinary study shows that red light/near-infrared phototherapy successfully impregnates 22% of severely infertile women, with a live birth success rate of 50%. Male gonads also like red light. In the study of sperm, near-infrared light therapy at 830nm significantly improved sperm motility.
At the 10th National Laser Biology Academic Conference of the Chinese Society of Genetics, the team of He Yanyan from the State Key Laboratory of Laser Technology of Huazhong University of Science and Technology reported that the human liver cancer cell line HepG2 was irradiated with a red LED with a wavelength of 650 nm for different times. The results showed that the use of low-dose low-intensity red LED can promote the proliferation of tumor cells, while high-dose low-intensity red LED can inhibit cell growth. That is to say, red light has a certain effect on treating liver diseases.

Red light is considered to be the spectrum of life because its light waves can easily penetrate the human body and directly reach bacteria, providing anti-inflammatory, antibacterial, protein solidification improvement, promoting blood circulation, enhancing immune function, and metabolism effects on the affected area. In human cells, mitochondria have the highest absorption of red light. After being irradiated with red light, the peroxidase activity of mitochondria increases, promoting metabolism, increasing glycogen content, protein synthesis, and adenosine triphosphate decomposition, thereby strengthening cell regeneration and promoting wound and ulcer healing. At the same time, it also increases the phagocytic function of white blood cells and enhances the body's immune function. Therefore, red light plays a very important role in human health.
