Objectives/Introduction: Schoolchildren are using multiple forms of technology late into the night without prudence or restrictions. Subsequently, their ability to stay alert and fully functional throughout the day is impaired. The aim of this study was to asses sleep disturbances and sleep hygiene in school children. Methods: Our study included a group of 80 school children (29 boys) aged 8 to 12 years (mean 9.4 StDev ± 1.2 years). The children's parents were online questioned by the Sleep Disturbance Scale for Children questionnaire (SDSC), questions regarding sleep habits. Results: According to the SDSC, the mean T score was 43.3. Twenty-three % of children obtained a normal and 77 % presented an abnormal score. The main affected scales were: ‘Disorders of initiating and maintaining sleep’ ‘Disorders of excessive somnolence’ and ‘Sleep hyperhidrosis’. The mean time of actual sleep was 9 ± 0.9 hours, 45% (36/80) slept 9–11 hours, 43 % slept 8–9 hours, and 12 slept less than 8 hours per day. Difficulties of falling sleeping had 44%, 57% of children had anxiety and fear when falling asleep. Forty-nine % of children presented hyperhidrosis, 33 % felt tired in the morning, and 15% were sleepy during the day. In the same time, 38% were using the gadgets more the 2 hours after 9:00 PM, and 36 % were falling asleep with them. Conclusions: The majority of the children present some sleep disturbances. The main one is sleep deprivation due to the overuse of different gadgets in the evening and before the time for sleep. Also, the usage of devices with a screen before sleep increase children's anxiety, those increasing sleep delay. Unfortunately, it is a modern trend that is misunderstood by the parents, by the children and the whole society. Frequently the sleep deprivation in children is considered something reasonable, and there are not applied measurements to improve that. Disclosure: Nothing to disclose.
