Basically, "studies" can say whatever they want. I know for a fact that I can stay out in the sun a lot longer with a tan than I can with sunscreen alone.
The scientists have apparently not studied me.
I doubt you have a unique skin where all the typical biological damage and DNA repair mechanisms do not apply to you. Imagine if scientists had to do an experiment on every single person in the world to prove a medical point.
I'm not saying everyone is the same, but I do find that a scary number of people believe their situation is unique when, more often than not, it's not true. There's definitely a range of skin reactions to the sun, or to any radiation. However, base-tanning gives an SPF of 2-3 (.Andy's link from the Mayo Clinic says up to 4), and even if you miraculously got SPF 10 out of your base tan, a
good sunblock is still more effective, cheaper, and better for your skin's health.
And besides, you're paying a lot of money to get an SPF of 4. May as well just sit in the sun outside your house for 20 minutes. There you go --- base tan. You'll get less of the more penetrating UV-A, but a bit more exposure to the less harmful UV-B.
And I'm not trying to start an argument. I don't care if you go to a tanning salon, just like I don't care if you were a smoker. In my first post, I simply answered the OP's question without ever mentioning the harms of tanning. I don't care if you tan. But if someone wants to talk about the harm of tanning beds, well then lets talk about evidence uncovered in research and studies on humans (yes, a wide range of human skin). Otherwise, we'd be commenting on hearsay, old wives tales, etc.
Fear-mongering, much? If the sun were as bad as you'd like us to believe, then the human race would have died out ages ago. Humans spent a lot more time outside in the past than they do in the modern world, and the race is still thriving.
And 100 years ago, our average lifespan was around 60. Our average lifespan 1000 years ago was far shorter than that.
Our ozone layer also filtered out more of the UV.
Also, like Andy said, we're living in climates we're not really suited for. It's not a coincidence that people with the darkest skin come from near the equator.
Anyway, you're right in a way. Go out and get in the sun. Whatever. Just know the facts. I tan. Well, not purposely, but I was a 5 minute walk from 2 different beaches, so a tan is inevitable.
