How does screen time affect your sleep cycle?

People who use these devices while lying down might be putting themselves more at risk since this position could aggravate reflux disease (heartburn) where acid flows up into the esophagus causing pain. Another harmful effect is related to blue LEDs used on all kinds of screens including mobile phones, tabs, and computers. These blue light LEDs have been found to be a potential health hazard for retina cells and might increase the risk of age-related macular degeneration, one kind of eye disease where central vision becomes gradually damaged.
