If you don't want to overdo it and you don't want to get a sunburn, I think I'd recommend you try and avoid the sun altogether.  Tanning is not an activity that’s going to increase your health or vitality, and I think it’s possible to have a sunburn from a few minutes of sitting in the sun.  If you’re worried about your skin health, it seems like an unnecessary risk.

Oh! Well, that does narrow down what you’re looking for. Sunburns are pretty unpleasant, so I’d say that if you don't want a sunburn you should definitely limit your time in the sun.

How long should I stay out in the sun for a tan?
user
I’m really not sure, since that’s really just a personal preference. Some people find tanning easier with a tan, others don’t. Some people think that if you have a nice tanned color then that makes you more attractive. It’s all about what you like.
