A few minutes exposure to UV isn't harmful, and is on balance likely benficial. Put it this way - I would get more UV collecting my mail in summer than you would on a tanning bed for a couple of minutes. And I haven't dropped dead. But a bright sunny day does make my mood brighter. Vitamin D deficiency and depression are much bigger issues than UV over exposure.
