This study aimed to examine university students’ attitudes toward human interaction and health by clarifying changes in their lives caused by the COVID-19 epidemic. A questionnaire survey on life changes due to the COVID-19 epidemic was conducted among 318 first- to sixth-year students in the Department of Dentistry, Faculty of Dentistry, Hiroshima University between November 2020 and February 2021. “Interaction with others” was influenced by changes in “face-to-face conversations”, but not by “non-face-to-face interactions” such as online interaction. “Interaction with others” correlated highly with “the frequency of going out”. “Health conscious”correlated only with “taking care of hygiene ”but not with “diet”, “exercise”, or “sleep”. The basic interaction with people might be face to face, and non-personal interactions had not evolved to the point where they complement face-to-face interactions. Going out was considered necessary for face-to-face conversations. “Health conscious” meant “taking care of hygiene” and not “diet” , “exercise”, and “sleep”.
