Right, it's a trade-off. The benefits of vitamin D, infrared spectrum light on the immune system, and blue light on hormone signaling likely outweigh some increased skin cancer risk if you are smart about your exposure patterns.

And obviously there's a lot more than just cancer that a healthy body and immune system is protecting you from.
