Influence of Chronotype on Health and Academic Performance of Students

The study is devoted to investigating the influence of chronotype on health and academic performance among medical students. The aim of this work was to identify specific features associated with different chronotypes in terms of well-being, psychological welfare, and educational success. Using surveys and testing methods, we established a distribution of chronotypes within the student population: most belonged to the “owl” type (48.1%), followed by intermediate types (“pigeons”) (27.3%) and early risers (“larks”) (24.6%). It was found that students with an intermediate chronotype exhibited better academic performance, achieving high session results (4.0-5.0 points). Other chronotypes demonstrated lower grades concentrated between 3.0-4.0 points. Additionally, differences were observed regarding attendance rates, self-reported feelings, and mood across various groups. High spirits were noted among students classified as owls, but this group also showed the highest prevalence of chronic diseases, likely due to sleep disturbances and increased stress levels. These findings emphasize the importance of individualized approaches towards education and scheduling adapted to biological characteristics of diverse chronotypes. Recommendations have been developed for maintaining optimal productivity and preventing health disorders tailored specifically to each student's chronotype.
