It affects each person differently though. Personally, I don't notice it at all. It is a bit harder to get up in the morning if it's still pitch-dark outside, but otherwise, I have no SAD-type effects. Others can barely function without those lamps that are white-balanced to match sunlight and programmed to gradually brighten up in the morning.
