Too much blue light can accelerate aging ... at least for flies
Excessive blue light can cause accelerated aging in flies because this exposure can cause cellular damage, according to a study released Wednesday.
Excessive blue light can cause accelerated aging in flies because this exposure can cause cellular damage, according to a study released Wednesday.
Because the signaling chemicals in the cells of flies and humans are the same, this discovery suggests another possible way blue light can harm people, said lead author Jadwiga Giebultowicz, a professor in the department of integrative biology at Oregon State University. These findings were published in the journal Frontiers in Aging.
However, even if scientists eventually discover a similar effect on human cells, it’s important to note that the extent of damage felt by people would be minimal compared to that seen on flies.
“What we are trying to convey is a word of caution,” Giebultowicz said. “The less blue light, the better.”
People are exposed to blue light from artificial sources, like electronic devices and indoor lights, and naturally from the sun. While exposure to blue light during the day can help with alertness and cognitive performance, it can also disrupt a person’s circadian rhythm if people spend time with screens before sleep. This can lead to several negative health effects.
