Abstract :
Introduction: Sleep is one of the most important factors in ensuring the health of the body, soul and nervous balance of people, and in human life today, this important factor cannot be ignored. The endogenous circadian system of an individual is one of the most profound biological mechanisms that affects sleep and mental health. Variation between individuals in the endogenous circadian system includes differences in the timing of behavioral and physiological functions such as sleep-wake rhythm, alertness, central body temperature, and hormonal secretion. There is a consensus about the essential role of sleep in mental and physical health with many studies pointing to the adverse consequences of disturbed sleep. The high prevalence of sleep deprivation and low quality of sleep in modern societies highlights the need for more and better research aimed at revealing the mechanisms of sleep regulation and function. Sleep deprivation includes the complete lack of sleep during a certain period of time or shorter periods of sleep. The most common reasons for sleep deprivation are those related to contemporary lifestyle, social factors, and work-related factors; As a result, this condition affects the characteristics of a significant number of people. The destructive consequences of sleep deprivation on cognitive performance, motor performance and psychomotor performance such as reaction time and memory tasks, physical, behavioral and cognitive changes and executive roles involved in more complex tasks and reduction of neurobehavioral performance, including alertness and memory, can be Cited . Therefore, since sleep plays an important role in maintaining the nervous circuit and helps maintain overall health and well-being, neuroimaging studies show that sleep deprivation affects many aspects of the structure and function of the human brain. and has a negative effect on cognitive functions. Objective: This. study was conducted with the aim of investigating the effect of sleep deprivation on memory functions on the Wechsler scale in the morning sleep type of female students in the dormitory of Kermanshah city. Method: The current research is a semi-experimental type with a pre-test-post-test design and a control group. The current research population includes all female students of the dormitory in the academic year of 2024. The initial research sample consisted of 200 female dormitory students who were selected through available sampling. The research tools include the Wechsler W.M.S memory test (1939) and the MEQ morning-evening questionnaire (1976). Findings: The covariance analysis of the data showed that there is a significant difference in the memory performance variable between the experimental and control groups (P<0.001). Considering that the average of the experimental group. compared to the control group had an effect on the dependent variable, sleep deprivation has an effect on memo ry functions in the morning sleep type andd causes disruption in memory functions that all findings are at the (001) level. / P>0)) were significant. Conclusion: The results showed that sleep deprivation causes impairment in memory functions and weak memory function, so it can be concluded that sleep deprivation has led to a decrease in memory functions..
