Many of us are used to falling asleep with the television or computer screen on. Perhaps you’ve even replaced the traditional bedtime book with the Kindle screen or the iPad, but these routines are depriving us all of some well-needed rest.
Neuroscientists suspect that the glowing lights of our laptops and smart phones affect our body’s internal light cues and in turn counteract natural sleep-inducing hormones. Staring at a computer screen late at night can trick your body into thinking its day time and, in the long run, can drastically alter the body’s circadian rhythms. Laptop screens and screens in general emit a specific type of blue light that makes it harder for our bodies to fall asleep.
