Abstract
Non-regular mental and physical activity of schoolchildren and students, excessive use of mobile phones, harmful habits (smoking and snuff), iodine deficiency, poor diet, lack of sleep are the main reasons for memory loss decrease is observed. In our experiments, long-term memory volume was up to 37% and short-term memory volume was up to 51% in 6th grade students (13-year-olds); In 8th grade students (15-year-olds), long-term memory was up to 83% and short-term memory was up to 61%; In 10th grade students (17-year-olds), long-term memory volume was up to 83% and short-term memory volume was up to 57%; In first-year students (19-year-olds), we found that long-term memory decreased by 68% and short-term memory by 49%. Decreased memory, in turn, has a negative impact on the mastery performance of pupils and students.

Our research was conducted in 6th, 8th, 10th grade students of 13th and 31st schools in Namangan (Uzbekistan) (100 students in each class) and Namangan State University (Uzbekistan) Faculty of Pedagogy, conducted in primary education and sports educational work students (100 people)
Summary
Actuality of the topic: The future of our country, which is developing in all areas, depends on how educated and intelligent students and young people are. It is known that under the influence of external and internal environment, excitation occurs in the central nervous system, especially in the nerve cells of the cerebral cortex, in the higher nerve centers This excitation disappears after a certain time, but its trace remains, and the trace of the effect left on these nerve centers that is called memory. Iodine deficiency in food negatively affects the mental development of children and adolescents and leads to memory loss [8; 4348]. Iodine deficiency disease impairs physical, mental, and sexual development in children and adolescents. In this disease, the level of thyroid hormones is reduced because thyroid hormones contain iodine atoms [9; 103]. Korsakov have shown that memory improves by the age of 20–25 years, remains unchanged by the age of 40–45 years, and steadily decreases [15]
