People living in Thailand spend approximately 2 hours traveling every day due to traffic jams and long distances from their home to the destination.[1] The problem is also faced by Thai adolescents, particularly high school students, who are susceptible to experience stress due to traveling to and from school. Thus, this study analyzes the relationship between stress and the number of hours high school students in Bangkok spend commuting to and from school by conducting survey research. The survey was conducted using online questionnaires given out to Thai high school students in Bangkok, where a total of 273 responses were collected and analyzed using Statistical Product and Service Solutions (SPSS). The result shows that commute time, leisure, and the change of transportation types are significantly related to stress with the p values of 0.27, 0.005, and 0.045, respectively. This indicates that stress increases in high school students are due to long commute times greater than 2 hours, less leisure time less than 3 hours, and transportation. Nonetheless, there is no considerable relationship between students’ grades and stress. Thus, travel time can influence teenagers’ stress levels, so children may consider studying near their home to prevent themselves from being stressed.
