A lot of Superstition was bound to the night of Lucia, which was considered as the longest night of the year. Which it was during some parts of the medieval in course of the displacement in the calendar. From Lucia they usually associated to the name of the devil Lucifer and thought that "Lussepär" or the frightened " trip of lusse" under the commando from Lucifer marched thru the night. Other use was the similarity between the word louse (Swedish lus) and Lucia - that night could you tell flies and lice to move out. The Day of Lucia was in common a day with working prohibition, it wasn't allowed to for example chop wood or make deeds, which were a good thought if you consider the drinking party from the morning.
