In recent years, the interaction of people with the surrounding ecological environment has become increasingly unsafe for health, namely the person' physical and mental capabilities. This is especially true of the younger generation, like students of higher educational institutions, who have weakened immunity due to a busy study schedule, constant mental overload and stress. That is, health, as a sign of the quality of life of a student, is associated with the ecological situation and lifestyle, therefore, is one of the main concepts of human ecology. The influence of additional negative factors, such as stress and restrictions associated with the Covid-19 pandemic, greatly increases the risk of developing students' mental health problems. Unexpected isolation related to Covid-19 has caused disruption to daily routines, especially in students. The sudden change in the learning environment and limited social interactions and activities posed an unusual situation for children's developing brains. The study aim is to investigate and identify the psychological threats posed by students of different ages (under 20, between 21–25, and 26-32) in this pandemic of COVID-19. It was found that 28.0% of students were often nervous and stressed in the age group under 20, in contrast to 26.5% and 11.1% in groups 21 to 25 and over 26, respectively. In the younger group of students, 10.2% of students never felt upset, in the group of 21-25 years old - 8.3% and over 26 years old - 5.6%. It was concluded that it is mandatory to assess the student's psychological health and to plan for necessary support mechanisms, mainly during the recovery phase, because depression, stress, fear of getting infected, fear of losing a loved one, fear about getting jobs and related academic issues, disturbance in sleeping pattern, increase in duration of screen time, etc., were found to be common among students of all age groups.
