For me, it doesn’t matter if it’s “cool” or truly cold outside. Once the temperature drops below 10°C, my body begins to protest. My shoulders feel heavy, I reach for anything warm, and my legs turn to lead.

From March through early October, I’m happy. I have energy, I want to go for walks, and I feel lighter and more motivated.

But once mid-October hits and the weather cools, I start to feel like a sloth. November is the hardest — I want to hibernate, and my energy disappears. I feel a little lift in mid-December because I love Christmas, and January 1st always brings a spark of hope. But by the second week of January, I’m right back in hibernation mode until March.

At least that was my pattern for years until I realized I was experiencing Seasonal Affective Depression (SAD).
