The Blue Light Emitted by Screens Damages Our Sleep
The short-wavelength blue light, emitted by the screens we watch, damages the duration, and even more so, the quality of our sleep. This is the conclusion of a new study undertaken by the University of Haifa and Assuta Sleep Clinic. The study also found that watching screens that emit red light does not cause damage, and sleep after exposure to it was similar to normal sleep. “The light emitted by most screens – computers, smartphones, and tablets – is blue light that damages the body’s cycles and our sleep,” explains Prof. Abraham Haim from the University of Haifa, one of the authors of the study. “The solution must be the use of the existing filters that prevent the emission of this light.” Previous studies have already shown that watching screens before going to sleep damages our sleep. It has also been found that exposure to blue light with wave lengths of 450-500 nanometers suppresses the production of melatonin, a hormone secreted at night that is connected with normal body cycles and sleep.   ...more
