Sunburns are a defensive response which the body does itself.
The skin cells detect that theyve been damaged by the sun, so when it comes time to divide they instead kill themselves. This is to prevent the spread of its broken DNA and is a natural defense against cancer.
And every mammal can get sunburns, so its a trait that evolved long ago. The sweat of hippo's is actually brown and is a sunscreen. Large sun exposure over generations caused this all to evolve. This indirectly confirms that the sun kills and that sunburns prevent sun-based genetic illness.
The planets been exposed to this level of light forever, so life's adjusted, but if the sun cranked up out of nowhere (or the ozone depletes) it'd cause a mass extinction.
