Several studies in the past have pointed out that spending too much time on gadgets can impact your eyesight or mental health. However, a new study suggests that it could also affect your aging process. The animal model study, published in the journal “Frontiers in Aging”, indicated that excessive blue light from gadgets, including smartphones and laptops, can accelerate the aging process.
“Excessive exposure to blue light from everyday devices, such as televisions, laptops and phones, can have adverse effects on a wide range of cells in our body, from skin and fat cells to sensory neurons,” said study co-author Jadwiga Giebultowicz of Oregon State University in the United States.
“We are the first to show that levels of specific metabolites – chemicals essential for proper cell function – are altered in fruit flies exposed to blue light,” Giebultowicz added.
Researchers had previously shown that fruit flies exposed to light “turn on” stress protection genes and those kept in constant darkness live longer.
To understand why high-energy blue light is responsible for accelerating the aging of fruit flies, the team compared metabolite levels in flies exposed to blue light for two weeks to those kept in complete darkness. .
Exposure to blue light caused significant differences in the levels of metabolites the researchers measured in the cells of the fly heads. In particular, they found that levels of the succinate metabolite were increased, but glutamate levels were lowered.
The changes recorded by the researchers suggest that the cells are functioning at a suboptimal level, which can lead to their premature death, and further explain their previous findings that blue light accelerates aging.
