Cultural differences between Ukraine and Western countries go very deep, extending beyond surface level habits to underlying assumptions and worldviews. Ukrainians tend to have a smaller personal space than Western Europeans and place more emphasis on hospitality, treating guests well for extended periods. Physical health is also viewed differently, with Ukrainians believing that being cold can cause illness unlike in the US. Superstitions also play a larger role in Ukrainian culture compared to more rational Western societies. Friendship implies closer relationships in Ukraine, where people tend to form relationships easily within social groups and clubs.
