Students exposed to blue light from computer screens or other digital devices including smart phones, got less restful sleep in a study by researchers at the University of Haifa in Israel. Data in the study show that, besides getting 16 fewer minutes of sleep, those exposed to blue light from screens also woke up more often during the night and woke up groggy in the morning.
