Comment Re:MIT natural alarm clock (Score 1) 417
I have used one for the last 5 years. The one I have is called SunUp (about $150 USD). I set the time of day I want "full dawn", attach a light. I've used 4 "flood" track lights, regular lamps, to a "pig light", and it slowly increases the light over 45 minutes, thus simulating a natural dawn.
As soon as I used it I immediately noticed I didn't have the groggy, punch drunk feeling of a normal alarm. I don't have SAD but I've always had a hard time getting up with an alarm, especially in winter when dawn comes much later.
According to a show I saw (Nova, TLC or something) the whole body, not just eyes, is sensitive to light. They put special "gel lights" behind test subject's knees and had the lights come on while they slept - had the same effect.
I can't recommend one enough.
