The "bare" Essentials

So for this season we are following Survivor. I haven't watched it in a long time. We are hosting a small group in our home for youth who come, watch Survivor and then get into the word. It is a really good night.

However, is it just me or is it a bit over the top in the skin showing department? In the very first episode they were only in their scanties with blurred-out buns a few times. It seems even more so in the second. What more can they take off over the next few weeks?! I mean is it really that hot and if so how come no one is getting sunstroke or burns from too much sun exposure?
