Abstract:	External factors during social distancing caused by the COVID-19 pandemic might have influenced human behavior and impacted the different chronotype’s profiles. This cross-sectional study evaluated the impact of social distancing in daily habits among different chronotypes. University students practicing social distancing in Southeast Brazil answered an online questionnaire that evaluated chronotype profile, sociodemographic data, and habits related to physical activity, eating behavior and sleep characteristics before and during pandemic. Likelihood ratio test, Kruskal-Wallis test and multinomial logistic regression analysis were performed (p<0.05). 527 students participated in the study. When compared to intermediate profiles, morningness profiles were more likely to increase their level of physical activity (OR=2.733, CI=1.025-7.503, p= 0.045) and the amount of food intake near bedtime (OR= 1.981 CI=1.073- 3.659, p=0.029), and were less likely to maintain regular schedules during pandemic period (OR=4.562, CI=2.045-10.173, p<0.001). Eveningness profiles who used to have regular schedules before pandemic had 56.1% less chances of maintaining this habit during pandemic (OR= 0.439, CI=0.217-0.886, p=0.022). They were also more likely to present better mood (OR=3.000, CI=1.125-8.004, p=0.028), and worsening in eating habits during pandemic (OR=2.913, CI=1.263-6.719, p=0.012). This study provides an alert for individuals to stimulate self-awareness related to behavior changes, especially considering the COVID-19 pandemic.
