Back Off of Blue Light
Smart phones, e-readers, tablets, computer screens, TVs, and digital clocks emit blue light, a short frequency of light that may be harmful to the eyes and disrupt sleep. Minimize screen time for several hours before bedtime to get a good night's rest. Wearing orange tinted glasses that block out blue light may also be helpful. Apps are available for your computer, tablet, and smartphones that prevent the screens from emitting blue light. Besides blue light exposure, it makes sense to power down several hours before bedtime to maximize your chances of getting a good night's rest. Cover up any displays that may be visible from your bed, like a digital clock. Black out curtains can block out ambient light from outside.
