There are some people I know who could be considered to be addicted to tanning. They don’t have SAD or anything, they just like to be tan all year round. It’s a bit obvious when you’re that way all year round, and frankly with the whole orange look you sometimes see, not a pretty thing. One of my neighbors as a kid was notorious for it as his skin was always orange and he looked like a withered up prune, it wasn’t natural, and even 10 year old kids noticed it. It was never said to his face, but it’s embarrassing. This being said, of course, with tanning beds, you run serious risks of cancer. You may think it’s not a big deal now. But just wait until you are undergoing radiation and otherwise to try to kill off the damaged cells. Then it won’t be so fun or worth it. But basically they say that if people annoy you by criticizing your tan or tanning habits, you have ever felt guilty or like you need to cut down on tanning, you’ve thought about it first thing in the morning, or otherwise, you are probably addicted. Not wearing sunscreen and tanning beds are always harmful. But if you have an addiction, it obviously increases the risk substantially because you are more likely to do it more.
