Hi all,
I've found my health starts to decrease in the winter months. During the summer with long evenings and pleasant temperatures I am extremely active, running most nights and spending a lot of time outdoors. I eat better and sunlight really does improve my mood. I'm more productive at work, even on hot and humid days. I'm better able to handle stress as I have more opportunities to go on long runs (which substantially improve my mental health). I get sick way less often and there is more colour everywhere, from bright greens to bright blues and everything in between.
This past winter has been particularly tough for me. The ground is sodden, which makes trail runs far more difficult. The wind, the rain and the darkness after work really make exercise outdoors more difficult. The lack of sun, where I literally need to self medicate with vitamin D to avoid deficiencies. The grey colour scheme to everything outside. I know some people love this time of year, but it personally crushes my soul. I am hoping to move abroad to do postdoctoral work after my postgraduate degree. It doesn't even need to be that warm in winter, just less wet and dark. There is a lot of work in my field of research in San Diego - 20C winters and 26C summers. That's my kind of climate!
