Here's my "N=1" anecdote: Not sure if I technically have SAD, but I definitely used to get depressed during winter in Chicago because the sun was NEVER out. Since moving to the Bay Area I've been noticeably happier. Beyond that, I have two full-spectrum lamps at home. I used to use one last year on my desk at home, but haven't used them lately. My desk doesn't get a ton of natural light, so I've considered bringing one to the office since daylight savings makes it SOOO dark. When I'm using the lamp, I experience a similar feeling to when I'm basking in sunlight. I feel like I am gaining energy rather than losing it. Sometimes it can be a bit bright, but the brightness doesn't hurt...it is just energizing. Really hard to explain, and again, sample size of 1 here, but the lamps can help in some cases. When I used it most recently last winter on my desk at night after a long work day, it definitely helped. But I found that it made it more difficult to go to sleep, so instead I don't use it, have f.lux running, and just try to get outside into the natural sunlight when I can for a little bit when I can carve out some free time. I live in California so might as well take advantage of that right?
