Catching up on my vitamin D

The high-pressure nestled over our area has given us two days of beautiful sunshine this weekend.  Two drawbacks... it's February and temperatures are hovering around 12 degrees, and the sunshine competes with my ambition to spend time in the studio creating.  I just can't seem to force myself to go downstairs, out of the light.  I figure it's OK, my body probably needs the vitamin D.  I'll listen to my body and wait for my time in the basement until after the sun goes down.  Bring on the sun!
