Fatigue is a physiological phenomenon that disappears through rest. The study of school fatigue is very important because the physical and intellectual effort of students is limited. The study was carried out on a group of 184 high school students from two Moldavian counties, in Romania. A questionnaire was applied with questions about the presence of fatigue, methods of spending free time and social relationships. Fatigue is rarely present in half of the students questioned. In 57.06% of cases, they find themselves tired in the morning. The time spent watching television (TV) is between 0.5-1 hour a day (41.84% of cases), and computer use is between 2-3 hours a day (46.19%). There are young people who have no friends and who do not spend their free time with them. Free time spent in front of the TV or computer is a source of fatigue and not rest.

Introduction: school activity is characterized by high physical and mental demands. Any failure to adapt these requests to the possibilities of the age group can be associated with school failure. Material and method: the study was carried out on a group of 208 students from the 9th grade from a National College in Iasi (54 students), a National College in Pascani (80 students) and from an Economic High School in Iasi (74 students). A questionnaire regarding school activity and the causes of the phenomenon of school fatigue was applied. The results were processed using Pearson's chi-squared test. Results and discussions: The students are constantly preparing only for certain subjects (72.59%). The young people from the National College in Iasi stand out, as we find numerous answers of "I do not continuously prepare for any subject", so the calculated differences are statistically significant (p<0.01, ƒ=4, χ²=14.254). In most cases (65.86%) adolescents admit that they have been trained how to study only in certain subjects. In the students from the National College in Iasi there are few explanatory answers in all the disciplines, so the calculated differences are statistically significant (p˂0.001, ƒ=4, χ²=19,465). Young people study for pleasure only in certain disciplines (86.53%). At the National College in Iasi there are no students who study for pleasure in all disciplines, so the differences obtained are statistically significant (p<0.05, ƒ=4, χ²=11.072). Fatigue is often present in 58.65% of students, with significant differences between high schools (p<0.05, ƒ=4, χ²=11.807). The students attribute the occurrence of this phenomenon to the numerous subjects they have to study (55.76% -statistically insignificant differences), the large volume of homework (51.92% -significant differences) and insufficient sleep (48.55% -statistically insignificant differences). Conclusions: there are many factors that generate school failure that must be known and carefully assessed in order to reduce the frequency of this phenomenon.

Introduction: it is necessary to assess the way students spend their free time in the final years of high school due to the poor results that have appeared recently in the baccalaureate exams. Methods: the study was carried out using a group of 202 students from the 11th and 12th grades from a National College (117 pupils) and a High School (85 pupils) from the city of Dorohoi, Botosani County. The young people filled in a questionnaire with questions about leisure activities and social relationships. The results were processed using Pearson's chi-squared test. Results and discussions: The time allocated daily for physical activity is mostly 15-30 minutes (23.76%) with significant differences between the two schools (p˂0.05). The time spent watching TV is mostly 0.5-1 hours (35.64%) with insignificant differences between grades (p>0.05). Most students (44.05%) do not sit at the computer, the calculated differences being statistically insignificant (p>0.05). When looking at social relationships we take into account friends, where in the majority of cases (32.4%) students have „one” true friend. This is a usual result because in this period of the adolescent's life the role the group of friends plays decreases, with significant differences between school years (p˂0.05). In their free time, they go out into town, mostly 2-3 evenings per week (28.71%), but there are also 31.68% negative answers. Parents are less concerned about school activity (“never” answers – 34.15%) with significant differences between grades (p˂0.01). Parents are also less concerned with the way their children spend their free time (“never” answers – 34.65%) with significant differences between school years (p˂0.05). Conclusions: there is a series of situations that guide us towards a modest concern for the future, both from students and their parents.

"Introduction: fatigue is a physiological phenomenon that disappears when lowering effort levels and when sleeping. Young people need at least nine hours of sleep per day. Material and methods: the study was carried out on a group of 246 high schoolers (9th and 11th grade) from three schools in Boto?ani County. Pupils completed a questionnaire with questions about the daily time spent sleeping at night, the presence of fatigue, the time of day and the day of the week when it occurs and the presence of sleep during the day (naps). The results were processed using Pearson’s chi-squared test. Results and discussions: most pupils sleep for 6-7 hours (37.80%) or 7-8 hours (33.73%) per night, with statistically insignificant differences between the two classes (p>0.05). Fatigue is often present in 46.34% of cases with insignificant differences between classes (p>0.05). The correlation between night sleep and fatigue shows significant differences (p?0.05). When waking up in the morning, 44.30% of young people feel tired, with statistically significant differences (p?0.01). The correlation between the time allotted for nighttime sleep and the presence of morning fatigue shows statistically significant differences (p?0.01). Most pupils in the 11th grade feel tired at the end of the week, while those in the 9th grade show signs of fatigue at the start of the week, the differences being statistically significant (p?0.05). The correlation between nighttime sleep and the occurrence of fatigue during the week highlights statistically insignificant differences (p>0.05). Napping is rarely present in most cases (46.74%), the calculated differences being insignificant between classes (p>0.05) Conclusions: insufficient sleep during the night is associated in most cases with the appearance of fatigue, an aspect that must be carefully studied and monitored from a medical point of view."
