SleepSleep is the time when people's brains are very active. Sleep has multiple effects on the brain from infancy through childhood. During these periods of life the brain develops a lot during sleep, which is why we fall into a deeper sleep. During infancy, the most drastic change in the baby's sleep pattern occurs in the first year of life. Newborns do not sleep through the night because they have not yet developed the sleep cycle (Lampl). Newborns sleep 12 to 18 hours a day. In a study conducted on 46 children it was shown that in the first sixteen weeks of the child's life there was a decrease in the total hours of sleep received per day. When newborns sleep it is important to keep in mind that the non-supine position poses a risk of sudden infant death syndrome (Smylie). Sleep can affect a person during childhood when they do not receive enough sleep. During this period the brain undergoes morphological changes such as pruning, synapse growth, and white matter myelination (Kurth). Sleep affects a child not only physically but also emotionally. It is common for this age group to develop insomnia, sleep disorders, breathing disorders and many other disorders (Baweja). Enuresis often occurs in childhood. Sleepwalking is common in childhood; It happens to some children that when they are sleep deprived they spend more time in deep sleep when they sleepwalk. Sleepwalking is common in childhood, but can also occur in adolescence and adults (Bell). The average teenager should get an average of 9 hours of sleep, however almost all teenagers sleep less (George). Getting an adequate amount of sleep can have consequences not only mentally and physically, but also academically. Adolescents may be tested to see how much sleep they get... half of article ......nd Psychiatry, 55(3), 273-283. doi:10.1111/jcpp.12157Smylie, J., Fell, D.B., Chalmers, B., Sauve, R., Royle, C., Allan, B., & O¿Campo, P.
