It's time to start thinking about light as a powerful medicine -- capable of providing tremendous benefit when used correctly, but requiring care and education in that use.

I sleep like a baby, which is to say I sleep in short spurts throughout the night and wake up abruptly at inconvenient hours feeling kind of cranky. For years now, I have fallen asleep easily but rarely am able to stay asleep. I wake up at the slightest noise or light. I wake up when my husband moves the top sheet a millimeter.
