I don't know that gillyweed will have done anything particularly for the temperature. Presumably they equipped them all with some sort of warming charm. Or perhaps they were expected to be able to manage that themselves.
None of them seem to be suffering hypothermia, however. Cold as it is, that would have done for them quite quickly.
