Why do 18 and 19 century Europeans like to grow beards?

Not only18.6438+Europeans in the 9th century. European whites, especially those in high latitudes, have thick hair and many men have beards. And because of poor sanitation and ignorance, I made a mess of myself. Many men grow beards because they don't pay attention to hygiene, because shaving is bound to be associated with washing their faces, bathing and brushing their teeth. Moreover, in the Middle Ages, many people used beards as napkins, grabbed them with their hands when eating, and wiped their mouths with beards or hair after eating.
