The main aim was to determine how a 25-minute nap impacts their cognitive functions. A specific 25-minute nap routine was implemented as an intervention within the study. It is important to note that the study was not investigating any diseases or medical conditions. Instead, it focused exclusively on the impact of napping on healthy individuals. The study was sponsored by the Higher Institute of Sport and Physical Education, Ksar-Said, and the Institut Supérieur du Sport et de l'Education Physique de Ksar-Saïd.
