The quality of sleep affects the physical and mental health status of children. The pathogenesis of sleep disorders in children is unknown, but it may be related to delayed cortical development that disrupts the normal sleep rhythm, resulting in symptoms such as excessive dreaming and sleep terrors. Although there is no fundamental solution to delayed brain development, it is worth paying more attention to the risk factors that cause its development, such as psychological factors and improper parenting. The most common sleep problems in children include teeth grinding, breath-holding, open-mouth whistling, excessive night sweats, bedwetting, and nightmares. The main factors affecting sleep problems in infants and children are the total length of daytime sleep, ventilation in children’s bedrooms, birth asphyxia, passive smoking during pregnancy, father’s occupation, and father’s sleep talking during sleep. The following are the main manifestations of sleep disorders: 1. Difficulty falling asleep or sleep disturbance The former is the inability to fall asleep easily, while the latter is manifested by poor sleep or easy awakening. As the age increases, the form of sleep disorder tends to be more adult. Therefore, do not overly tease the child before bedtime, and let the child develop the habit of getting up on time. 2, sleep rotation: neurological development is incomplete New mothers often complain that their children sleep obviously sleep this head, but wake up when the head do not know which side to turn, a night do not know how many times to help him adjust. In fact, the body rotation of infants and toddlers in their sleep is mainly due to their incomplete neurological development. If you find that your child is suddenly shouting in his sleep, maybe he was frightened during the day, or maybe he is dreaming, if it happens only occasionally, it is mostly for physiological reasons. However, if it occurs frequently, it may be pathological, and the child should be taken to the hospital for examination at this time. 4.Dreaming The part of dreaming other than epilepsy belongs to physiological phenomenon, if more times, sleep monitoring is needed. Because of the early sucking reflex, children like to eat the blanket when they sleep, just like they like to suck the pacifier, it is just a habit, but it is not excluded that it is caused by the lack of trace elements, lack of zinc and iron can also lead to children like to eat the blanket when they sleep. If the child has this habit, you can let the child suck the pacifier to sleep, if you are worried about it, you can go to the hospital for examination. 6, sleepwalking syndrome may be caused by epilepsy. During sleep, the child suddenly gets up, like drunk, expressionless, does not speak, walks around the room, and may avoid obstacles. After a few moments, the child goes back to sleep on his own. Sometimes the child falls asleep immediately after tripping on the roadside and cannot recall the dream experience after waking up. Sleepwalking may originate from neurosis or may be a manifestation of epilepsy and requires further examination.
