What happened to reading a book at night as a way to unwind? Last night, I caught my son fixated to his iPod, at bedtime, when he should have been ramping down from his day, preparing his body for a good night’s sleep. I know Peter is not alone in the habit of using electronic devices before retiring in the evening. When the eyes are exposed to bright light at night, it signals the brain that it is time to wake up to milk the cows. Is it any wonder why half of all Americans have difficulty sleeping?
