In the period when the Crew Dragon Demo-2 mission was initially docking with the ISS, before the hatches were open, one of the tasks was to "dry the suits". They reported on the status later, indicating they had been drying for over an hour.
Is that to remove humidity from wearing the suits? Or some other reason?
Sorry, I can't get timestamps, but it's while docked and (only) the first hatch is opened.
