Winter is upon us, and for those that live far north of the equator, it can be a time of year we brace ourselves for. It is the season that bridges the end of year to the new, and a time to truly rest and reset. Along with that, there are naturally fewer sunnier days, shorter days, and less movement. These changes can impact our circadian rhythm, as well as our serotonin and melatonin levels. For some this causes symptoms of Seasonal Affective Disorder (SAD).
