Did you know that our brains are hardwired to wake us up in the presence of certain wavelengths of light?  Did you know that electronic screens, such as televisions, iPads, and smartphones all emit that kind of light?  It’s true!  In addition to stimulating our minds, watching screens before (or worse, while in) bed actually sends signals to the part of our brain that tell us it’s time to wake up.  So for greater ease falling and staying asleep it’s essential to turn off all screens at least an hour before bedtime.
