Snow-lovers rejoice—winter is coming!

And no, this isn’t an allusion to Game of Thrones. With the end of Daylight Savings, the days are becoming darker earlier, which for some can mean the onset of the winter blues. The medical term for this is Seasonal Affective Disorder (SAD), a condition caused by a mélange of changes in our biological clocks, serotonin levels, and melatonin production, all of which affect our mood.

While many of us are familiar with SAD, there are, in fact, people that get SAD in reverse. For a small group of people, the dark days of winter don’t elicit depression, but renewed vigor and improved mood.
