Learning for children is a necessary stage in the development of personality, which helps the child to more easily acquire the necessary knowledge to further establish the individual. Оn the other hand it is a difficult stage in life of young people who lose the ability to communicate offline, especially during distance learning. It is difficult for children to adapt to the constant stay at home, to communicate with classmates and friends online, to adapt to the new rhythm of life and the dynamics of learning. Staying more than half of the time at the computer with a layer of psychological difficulties in the conditions of distance learning leads to constant stress and chronic stress. The modern educational system has changed so much in the last two years that the student must constantly adapt to new learning platforms and innovations. And the inability to clearly see and do laboratory classes in many subjects, self-study, even physical education classes leads to chronic stress.
 Stress is becoming an increasingly global problem, especially among children, because it negatively affects their lives and health, the progression of bad habits, and in turn, disorders of the dental system. Therefore, it is important to study the problem of social emotional chronic stress in the educational activities of students in terms of distance learning and its impact on the formation of disorders of the dental system.
 To reduce the impact of stressors, children use bad habits: sucking fingers, biting nails, pencils or pens, sitting in front of a monitor with his mouth open, despite a positive breath test (presence of nasal breathing), in the same position resting his head on his hands, causing chronic injury in this area. According to many studies, this may be the result of a person's adaptation to existing chronic stress.
 Our study was based on a quantitative study conducted among school-age patients who have bad habits (sucking a finger or other objects, breathing through their mouths, resting their heads on their hands while listening to an online lesson) through a secret questionnaire that collected information on the most stressful areas of life and distance learning under quarantine.
 The article presents the results of an anonymous survey of 60 patients, which includes periods of onset and progression of a chronic habit, the presence of various stressors, the reasons for poor performance. Our results of a secret survey indicate the state of chronic stress of students, their being in a state of social stress due to new living conditions, frequent changes between periods of live communication and distance learning, psychological problems in the family, emotional relief during the habit. Due to the fact that children live in conditions of chronic stress, they lose motivation to learn. They do not get pleasure from it, but in turn seek help in habits that, according to our patients, help reduce the impact of stress on quality of life and their own emotional state. The results of the study explain the formation of adaptive responses of the body to the stress factor (E. Gelgorn, W. Canon) and confirm the relationship between chronic bad habits in children under social stress.
