Elizabeth learned she couldn't get her light at her breakfast table. Now she starts her day in a sunnier room and no longer has trouble falling asleep.

Working with her therapist, Mary found her depression was better when she got at least 70% of her daily light.

Steve, like many of our users, found that he got 0% of his light on a typical day in the office.

I work from home, typically paying zero attention to the world (or sun) outside my little dungeon. A few days of rocking my SunSprite has turned me into my dog: noticing all the sunny slivers in my apartment and basking in them a bit. I love it, even if she's getting annoyed that I'm stealing all the good spots. Added bonus is that I've also become a human sundial, which is a fun party trick.
