Hygiene in Colonial America:

In colonial times in North America, most people did not have good hygiene. Since there was not very much water, they didn't bathe or brush their teeth that much. Many people had wooden teeth and people only washed every like 2 to 3 weeks or washed off with a wet cloth everyday.

Hygiene in Europe and Asia:

Europe: In colder places in Europe, they shower less than other cultures because it isn't as hot where they live. It happens to be a myth that European women don't shave but, a vast majority of them actually do. Another myth that Americans created is that all Europeans have bad teeth, but in reality they have mostly the same hygiene except Europeans are more natural and use less cosmetics than Americans. 

Asia: In some of the poorer places in Asia do not have clean water to stay clean and healthy. There are many organizations that are giving clean water to the poor places that don't have that very important supply.
