It's not a matter of stress -- it's a matter of contributing to cataracts and skin cancer.
UV light is used for vitamin D synthesis in many organisms, including humans. However, all UV light is damaging to body cells. There is NO SUCH THING as a "safe" tan where UV is involved. For humans, there are any number of ways to obtain vit D without sunexposure as it is included in most vitamin supplements and some foods are fortified with it (especially milk and cereals).
