This study is to examine whether night-time students' working status has an negative effect on their learning at night, and whether their work and their study would respectively induce the working stress and learning pressure, or even damage their body-minded conditions? A quantitatively statistical research method was conducted and a modified and integrated questionnaire based on some measurement scales existed already was used to collect data from a sample of night-time students in Kainan University. The working stress, learning pressure which are two of variables related with the body-minded condition, were tested on their influence. The statistical results show that the body-minded condition of nearly 35 percent of night-time students is bad, and that of 13.6 percent of them is seriously bad. In addition, our research results also show that no strong correlation exists between the body-minded condition and students 'job status, and no significant difference for working stress and learning stress on body-minded condition. In other words, although learning pressure and working stress do exist on night-time students, there is no evidence to support the hypothesis that they two are the main reasons to result in the bad body-minded conditions of students.
