Researchers from Oregon State University have found evidence that light from the screens of smartphones and other digital devices can affect basic cellular functions of the human body. Senior author of this study, Dr. Jadviga Gibultovich states that mobile devices, laptops, televisions can negatively affect many cells in the body, including brain cells, skin cells and fat cells.
Using the example of fruit flies, scientists have shown that when exposed to blue light, the amount of certain metabolites, i.e. chemicals necessary for cells to function properly, changes. As a result, flies activate genes that protect them from stress. At the same time, insects kept in complete darkness lived longer.
Especially during the study, it was revealed that the level of metabolite succinate increased and glutamate levels decreased in flies. According to Gibultovich, succinate is needed to create the necessary fuel for every cell to grow and function. Glutamate is responsible for communication between brain neurons.
The results of this study show that cells die sooner after exposure to blue light. This can cause premature aging of the body if it is exposed to too much light.
At the same time, the expert noted that humans are still not heavily exposed to blue light compared to flies. Therefore, the damage to their cells may not be that severe.
