It doesn’t take much to throw your circadian rhythm (your body’s internal sleep clock) completely off balance. Unfortunately, once you’ve done that, it can take quite a while to get your rhythm back so you can get a good night’s sleep once again. The really strange news, however, is that your alarm clock may even be one of the culprits keeping you up nights.
Kids these days! I never thought I’d say those words, but here I am worried about how much time kids spend on the computer and watching television. Screens have infiltrated our homes and they’re not going anywhere soon. They’ve become a ubiquitous part of our work lives, social lives, and home lives. And kids are not immune. An increasing number of children have televisions, computers, cell phones, and tablets in their bedrooms. I’ve written before about how light from phones, computers, and televisions can affect sleep. The blue light from theses devices simulates daylight, confusing the brain into thinking its time to wake up. This is bad news if it’s time to go to bed. New research shows this type of light has an even more deleterious effect on children.
