Spent extended time in the sun today. Really transforms my outlook, after 45 min.
I must be sorely Vitamin D-deficient these days.
We hardly get sun here. Got a depression last fall, probably lack of vitamin D. Been staying on top of getting supplements.
Need UVB light on your skin for vitamin D, and you need blue light in your eyes for helping with seratonin levels. Both are key. I got a SAD lamp at work I use in the morning or at the start of a night shift.
The one thing I don't like about winter is how it's dark all the time. It never actually affected my mental health, but it did last year, so it's something I try to be more aware of now. On my days off I try to get up earlier so I can catch some natural day light and bundle up and go for a walk. Have not been doing it as much as I should though. On days where I work, well I don't see any daylight at all so just have the SAD light.
