Proper sleep habits are needed for quality and adequate sleep. According to the National Sleep Foundation, these habits include practices such as regular bedtimes, sleep routines, screen restrictions before bedtime. A circadian rhythm develops until the age of 6, and after the age of 6, the habit of being a night owl or getting up early is observed. In addition, with the school starting age (after the age of 6), children enter into a busy schedule and their sleeping habits may change. Adequate sleep time for school-age children is 9-11 hours.

With the age of starting school in children; Due to the roles brought by school, lessons and social obligations, problems such as delay in bedtime and shorter sleep time are observed. Shortening of sleep time causes sleep deprivation. sleep deprivation; It is defined as a delay in bedtime and a shorter sleep time than it should be, either intentionally or due to daily actions. sleep deprivation in children; It causes decrease in cognitive performance, poor school performance, weakening of mental abilities, daytime sleepiness, lack of physical activity, obesity and changes in dietary habits (short sleep calorie foods and carbonated drink consumption; adequate sleep fruit and vegetable consumption.

Sleep hygiene is a set of behaviors that aim to improve sleep quality by eliminating bad sleep habits. Sleep hygiene is a cost-effective method that is performed without the need for any additional material, consisting of both environmental and behavioral habits.

School is a very effective environment in developing healthy behavior, and the home environment is important for the behavior to continue. For these reasons, in our study, school-age children who do not have any health problems will be handled using both the school environment and the home environment. The research to be carried out is unique from other studies in that it aims to create behavior in children by using the school and home environment together and by attracting the attention of the materials used by the children. As a result of the examinations (yök thesis, google academic Turkish, etc.), our research is the first in Turkey in terms of being aimed at healthy children, the intervention for both children and families, and a quasi-experimental research design.
