One can water, the Tobbe, a river, lake or sea.The middle-century did not wash themselves, and naked was not done childish at the time. About sex anyway. The prudery would only come with the Reformation and the Victorian era. Most people find dirt and old sweat not smell attractive, which is probably an evolutionary mechanism. After all, clean people are getting sick less quickly and are also more likely to reproduce.
The myth that mediators were unhygienic viezeriks is mainly due to the cities that were indeed not too fresh.However, this was also the same for ancient cities. Dirt was peamed on the streets, and pigs and dogs were roost in their hearts. The shit lay everywhere (either from dogs, horses or pigs, either from people because all the garbage was tated on the street), as well as decaying waste. Horse and dog carcasses just rot away where they lay, no one bothered to clean them up.
The stench must have been terrible but everything gets used.Whoever has been in a city in a developing country may have an idea what I mean. Everywhere a lot of people pronounce live on each other it becomes a nasty mess, unless daily cleaning and dirt drainage is ensured.
Furthermore, science was still not so far.For example, cats were desponded or killed (a folk amusement was a cat living in a sack burning alive), not knowing they were feeding rats who soiled food and spread the plague. And instead of avoiding rats and their fleas when the plague broke out, they turned against the Jews. Only in the 19th century, John Snow would lay the link between pollution of water with stools and cholera, before that it was often drunk from the same water as in which one dumped animal carcasses and human toilet waste. In fact, because religion claimed to be able to declare the whole world, religious declarations were sought in diseases; It would be a punishment of God and as in the story of Job you have to undergo it.
I realise that I went beyond answering the question, where I wanted to go into the image of the ‘ unhygienic middle-century ‘.
In contrast to what is generally thought, people did wash themselves in the Middle Ages.Also soap was not unknown. How one did that lay at the place and time in which one lived. One lived near a river, the sea or one more than one went there in bathing and swimming. Especially in the warm months. In cities and Rotere villages there were also bathhouses. In The early Middle Ages, it was often the Roman baths. You can compare such a bathhouse with the current sauna. There was a hot room to sweat, a cold bath to cool off and a lukewarm bath. Richer humans had often themselves a bath possibility. In the northern countries, a remote home often had a sauna (Badestoa, Bastu, Banja) In Finland This is still the rule. Also remember that sweating in a sauna cleanses the skin more thoroughly than soap. (Also a sauna is sterile, this can counteract diseases. In Finland, women in the sauna, although with the stove out but still in a sterile room, were
The bathhouse disappeared in Western Europe in the sixteenth and seventeenth centuries, partly because of the syphilis epidemic which, it was believed, was scattered through bathhouses.(One bathed just like now in the sauna indeed naked and mostly mixed) Then also took the habit to wash himself off, in any case under the richer top layer. Handworkers were more likely to wash. To expel the stench, one went to use odour waters
In cities washed themselves in bath houses against payment in more rural areas a family had often its own wooden bath.
It is a misconception that hygiene in the Middle Ages did not exist.
Instead of water from the faucet one can filled with water.Instead of every day under the shower, occasionally in bath.
There was also no toilet paper.So food you did only with the right hand. Later in the Middle Ages, there were special servants for the richest to cleanse your posterior. Really a job
Then the rich did not have to use one hand, but the use remained quite a long time.
Soap already exists much longer than you think.It was only costly and was used perhaps by ordinary man weekly instead of daily:-)
