I have found that bumping the humidity and leaving the snake alone from when he/she turns opaque has worked best for my snakes when it's time for them to shed. I always make sure the water bowl is filled appropriately so the snake can fit and soak when/if THEY CHOOSE to do so. I don't handle them or stress them any further than the shedding process already stresses them. Just think, if your body was going through something like that, and your eyes were clouded over and you were more or less blind, would you want to be bothered and dropped into a pool? I wouldn't want that done to me. The only time my snakes seem a little scared or defensive is while they are in shed and I'm cleaning/watering their enclosures. Otherwise they tend to be absolute sweethearts. This leads me to believe they prefer to be left alone during sheds. Since they aren't able to speak, I "listen" to their body language, and it seems to be working well for me, and primarily, the animals.
