I'm at 52 deg N and an enthusiastic convert to D3 supplementation. Yet there are other factors which make going out into the sunshine pleasant. UV light causes nitric oxide to be released from the skin, relaxing the blood vessels. Also I think just seeing brightly lit outside objects and moving about feel good.
