New Study Says Light Emitted from Smartphone Screens and Taking Selfies  Can Cause Premature Aging and Wrinkles

A new study says light emitted from smartphone screens and taking selfies  can cause premature aging and wrinkles

Blue light exposure also decreased amounts of the energy molecule ATP in addition to impairing cell activity. Blue light also reduces the amount of molecules necessary for cell communication. The fruit flies age more quickly as a result of these impacts, and they also pass away too soon.

Blue light research involves fruit fly experiments, which are important, but there is still no data on how blue light affects people. Jadwiga Giebultowicz, lead author of the study hopes that her research will be taken up by a medical professional who will use it to treat people. She believes the consequences won’t be as dramatic. The blue light that the fruit flies were exposed to was quite intense—more so than what people normally experience. Giebultowicz stated, “Humans can argue that blue light is an environmental stressor, like other stresses that we encounter, such harmful substances and so forth.”

Although there are several advertisements for blue light-blocking eyewear, the issue extends beyond vision. Fruit flies were chosen for these research because they can test “mutant flies” that have no eyes at all, in addition to having cells that are comparable to those of humans. The effects persisted even in the absence of eyes, and the light was still absorbed by skin and fat cells.

The NIH reports, the widespread use of light emitting diodes (LEDs) and the rapidly increasing use of smartphones, tablets, laptops and desktop computers have led to a significant rise in the exposure of human eyes to short-wavelength visible light. Recent studies show that exposure of human skin cells to light emitted from electronic devices, even for exposures as short as 1 hour, may cause reactive oxygen species (ROS) generation, apoptosis, and necrosis. The biological effects of exposure to short-wavelength visible light in blue region in humans and other living organisms were among our research priorities at the Ionizing and Non-ionizing Radiation Protection Research Center (INIRPRC).

Recent studies aimed at investigating the effect of exposure to light emitted from electronic device on human skin cells, shows that even short exposures can increase the generation of reactive oxygen species. However, the biological effects of either long-term or repeated exposures are not fully known, yet. Furthermore, there are reports indicating that frequent exposure to visible light spectrum of the selfie flashes may cause skin damage and accelerated skin ageing.

In this paper we have addressed the different aspects of potential effects of exposure to the light emitted from smartphones’ digital screens as well as smartphones’ photoflashes on premature aging of the human skin. Specifically, the effects of blue light on eyes and skin are discussed. Based on current knowledge, it can be suggested that changing the spectral output of LED-based smartphones’ flashes can be introduced as an effective method to reduce the adverse health effects associated with exposure to blue light.
