Secrets Behind Scrolling: How Nighttime Screen Exposure Affects Sleep, Health, and Daily Life

We are exposed to blue light today more than ever in history. However, little is known about the long term impact of this societal shift. The objective of this review is to critically evaluate the health effects associated with exposure to light emitted from technological devices—particularly during the pre sleep period—with a focus on its impact on sleep quality, overall health, daily routines, and cognitive performance. The studies in this review demonstrate that light has a negative impact; therefore, we provide advice on navigating this in the real world. To minimize blue light’s effects, individuals should try restricting technology usage before bed and ensuring you have plenty of exposure to natural blue light during the day.
