It also seems fitting for a snake, since when you read it as it's spelled, it sounds like a hissing sound.

But yeah, shedding can be a stressful time for a snake. Their eyes get obstructed by fluid, so they can't see well, and I'm sure the stages of shedding can't be too comfortable. So yeah, it's best to leave them be for the week or so that they're in the shed stages. Just bump their humidity up to 70-80%, and leave them be to do their thing.
