Stress and stress management play a major part in the modern lifestyle when considering wellbeing. Short time stress can work as a motivator and is not necessarily a bad thing, but high stress levels in the long run are linked to burn-out. This may lead to expending person’s psychological resources and can cause a long time absence from proactive actions. Our sample included 17 students who were instructed to keep diaries for one week and describe their feelings during studying activities. Combining the diaries and Moodmetric data allowed separating the different studying activities from the data and also differentiate non-study time from studying. We found a strong correlation between non-study and study Moodmetric value averages. Even when comparing daily Moodmetric values, the correlation was strong and significant in the 95% confidence level. We got 53 non-study and study average pairs from the students. This lead to the assessment that stress levels are a comprehensive case, where it is difficult to determine all the causing factors. The sample size was not large enough to make reliable deductions from single studying activities. With larger sample sizes it would became more reasonable to research individual activities. It would also be beneficial to extend both the time students wear the rings and the time they keep diaries, so we get longer and more reliable periods of students‘ life and observed arousal levels. This could also allow interventions for highly stressed students.
