The Blue Light Emitted by Screens Damages Our Sleep
University of HaifaA new joint study by the University of Haifa and Assuta Sleep Clinic has found that exposure of two hours prior to sleep to the blue light emitted by screens damages the quality of sleep. Exposure to screens that emitted "ordinary" red light, yielded similar results to sleep without exposure to light at all. “Fortunately there are various applications that filter the problematic blue spectrum and apply a weak red filter, reducing the damage to the darkness hormone melatonin,” explains Prof. Abraham Haim, one of the authors of the study
