"deciding that sitting underneath some fluorescent lights is better than going outside and getting some sunshine."
Has it occured to you that in certain climates, spending an hour outside every day in freezing winter temperatures isn't the best option, particularly when you have certain medical conditions like reynaud's syndrome?
Yes. Has it occurred to you that I don't need a professor and chairman of psychiatry at the University of North Carolina School of Medicine, supported by taxpayer money, to tell me that sunshine (that would be "broad spectrum light") is good for us? This has been known since the days of Columbus, for crying out loud.
By the way, I think it's called Raynaud's Syndrome.
