Sleep is a biological necessity of every living being. Although many are unaware of this, sleep is very important for the health of the entire human body. In addition to being necessary for the recovery of the metabolism and stimulating the regeneration of the organism, sleep also plays a major role in the growth, development and recovery of all cells, the restoration of the sensory system and the stability of the memory process. Due to increasingly stressful and hectic lifestyles, certain sleep difficulties may occur. Unfortunately, they are often overlooked, thus remaining unrecognized and undiagnosed as sleep disorders. Sleep disorders can be prevented with good sleep hygiene. Sleep hygiene includes several procedures and habits important for falling asleep quickly, and it also contributes to feeling fresh and rested during the day. Evening rituals fall under these procedures and habits, but creating a pleasant atmosphere is also of great importance. It is necessary to adjust the room temperature, choose bedding made from breathable and natural materials, ventilate the room often and take care of light and noise sources. The purpose of this paper is to examine sleep hygiene in younger students and whether sleep difficulties occur among them. Data were collected via a questionnaire, and a total of 64 students ranging from the first to the fourth grade of the Elementary School "Matija Gubec" in Jarmina participated. The analysis of the obtained results shows that most students have a highly developed awareness of the importance of sleep and its role for human health. Also, the percentage of students who experience certain disorders such as bad dreams and waking up at night is relatively small. Students do not need to drastically change their evening rituals, but only reduce the use of technology, and increase activities such as reading and listening to music.
