According to a questionnaire survey, around 2% of female students use parasols. They use parasols not only for sunshades but also for the psychological effects of fashion and coolness. The parasols reduce the strength of ultraviolet rays by 75-95%, and lower the head temperature by more than 10℃. In addition, they reduce the dazzle by 83-97% , except for white and yellow parasols. In this investigation, the white and light colors are preferred rather than dark colors as parasols, but it was clarified experimentally that the effects of the sunshade were higher in the dark color parasols.
