The display screens equipped with contemporary electronic products almost inevitably produce blue light. Previous academic studies have shown that blue light can affect the normal secretion of melatonin by humans. Melatonin is a hormone that regulates the normal working hours of humans or regulates the circadian clock. Long-term use of electronic devices at night can lead to insomnia or delayed sleep. The latest research reveals that the potential hazards of blue light are greater, which may accelerate human aging, cause retinal damage and damage brain cells.
The research team at Oregon State University used Drosophila for blue-light damage testing. Drosophila has the same cellular and developmental mechanisms as other animals and humans. The researchers placed the flies under a blue LED for 12 hours, and the blue light emitted by the fixture was the same as the blue light emitted by smartphones and tablets. In the control experiment, the fruit flies were placed in an environment of complete darkness or filtered blue light, while the fruit flies irradiated by blue light showed brain neuron damage compared with the control group. At the same time, the retinal cells of Drosophila are damaged by blue light. The ability of the fruit fly to climb the outer shell or wall after the retinal cell damage is also significantly reduced.
The research team said that the blue-light accelerated aging of fruit flies is a shock to everyone, and the research team also conducted in-depth research. While blue light will greatly shorten the overall lifespan of fruit flies, it is clear that blue light will also cause the same situation for humans, and blue light will eventually accelerate human aging. Especially nowadays, more and more electronic devices and the popularity of LED lighting, more and more human exposure to blue light for a long time will inevitably affect the overall life of human beings.
