How are the holiday blues tied to SAD?
It’s not difficult to confuse holiday depression with SAD because of the timing. While some people with SAD begin to feel badly as early as September and October, a large number really don’t feel the major slump until after Thanksgiving and towards Christmastime. They’ll know, however, that there isn’t some emotional connection with the holidays that’s triggering their depression if it doesn’t let up until April or May, because a holiday depression will pass shortly after New Year’s. January and February are the worst months of the year for SAD symptoms.
