Whether for work or entertainment, the truth is that the mobile has become an essential element for a large part of society. Closer to a powerful computer than to a classic telephone, from the smartphone you can not only talk, you can also browse the Internet, save all kinds of data and even watch movies, series or football matches. The report of Mobile Status 2022published by the analysis company App Annie, assured that the daily use of the mobile rose in 2021 until 4.8 hours on average daily.
A study with flies
Scientists have found that when fruit flies exposed to blue light (in an amount greater than that emitted by phones and laptops) for 14 days, they show signs of impaired cell function and neurodegeneration, or aging.
The study divided into two groups to insects. One was exposed to blue light continuously for 10 to 14 days, while the second was kept in constant darkness. After this time, the researchers analyzed the cells in their heads for differences.
Those exposed to blue light for 14 days they had higher levels of the chemical succinate, suggesting poor energy production. They also had lower levels of glutamate, a key to cell-to-cell communication, which the scientists said indicated the onset of neurodegeneration.
Biologist Jadwiga Giebultowicz, who led the study, warns that this light could have a “detrimental effect on a wide range of cells in our body.” “Our study suggests that avoiding excessive exposure to blue light can be a good strategy anti-aging,” he adds.
Although the light the flies were exposed to was much stronger than that emitted by phones and laptops, and continuously for up to 14 days, rather than just a few hours, the scientists said their results suggested that light could trigger cell changes that accelerate aging. They even suggested that blue light could cause “premature death.”
