Suntans are unhealthy. It's true. I'm not sure that my Northern European and British Isles ancestors ever had to deal with this.
When you get a sun-BURN that means that the sun is actually BURNING YOUR SKIN. And the tan you get? That's your skin cells dying as they turn brown and then FALL OFF. And while it's happening it's incredibly itchy in places where you can't reach (like the middle of your back). And when your scalp peels it looks like dandruff to everyone else.
Feel sorry for me.
