There’s something to be said for getting your (natural) dose of Vitamin D, beyond what the vitamin itself provides.
The sun has that uncanny ability to pick up one’s mood (just as, sometimes, those rainy days can make you feel more glum. No offense, rain, we love you…but the dreary coloring and lack of direct light can definitely weigh on the temperament!) I don’t ever sit out, per say – not so gentle on the peau – but it is incredibly important to get outside and jam in the sunbeams every so often.
I knew someone once who was prone to down moods…often. One day she called me and said “I was looking at the shades in my room – they were down. They’ve ALWAYS been down. But I thought of you for some reason, and that you would say I needed to show the sun my face… So I opened them… I felt the difference right away! I couldn’t actually believe it.” She was truly and sincerely taken by the immediate flood of warmth and good feeling – it can actually be instantaneous.
