Here&#x27;s my &quot;N=1&quot; anecdote:<p>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&#x27;ve been noticeably happier.<p>Beyond that, I have two full-spectrum lamps at home.  I used to use one last year on my desk at home, but haven&#x27;t used them lately.  My desk doesn&#x27;t get a ton of natural light, so I&#x27;ve considered bringing one to the office since daylight savings makes it SOOO dark.<p>When I&#x27;m using the lamp, I experience a similar feeling to when I&#x27;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&#x27;t hurt...it is just energizing.<p>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&#x27;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?
