Yes, in the real world, most people prefer nudity. Google, Facebook, and even TV platforms airing our content however, aren't nudity friendly, and we've had to do a lot of blurring in episodes. Not to mention, many middle eastern countries are very strict and may even deny airing the blurred content, so it's easiest to have the on-camera individuals clothed.

It depends on the culture, location, and whether or not it is public, private, or co-ed. Co-ed community sauna environments tend to do this, but many locations do not require this.
