Humans are not nocturnal...we are designed to set our body clocks to the rise and fall of the sun. Unfortunately, Mr. Edison invented the light bulb, and the "artifical sun" messes with our body clocks. Any bright light (TV, monitor, iPad, etc.) before bedtime fools your brain into thinking it's day. So ge the above out of the bedroom, dim the lights in the evening, read a book or listen to music. Then go into the bedroom for sleep.
