The symptoms of sleeplessness in children may be caused by a deficiency of some trace elements in the body, such as calcium or zinc deficiency, or they may be physically ill and not feeling well. It could also be due to sleeping more during the day or being more active during the day and being a bit hyperactive. Therefore, if your child is not sleeping, it is best to go to the hospital for a checkup to rule out the possibility of illness and, if necessary, to have a blood test for trace elements to see if there is a possibility of calcium or zinc deficiency. Children should not sleep too much during the day, nor should they have too much activity or too much activity, as this will have an impact on sleep. If the symptoms of sleeplessness appear, you need to go to the neurology or pediatrics department of the hospital for examination and timely treatment, otherwise prolonged poor sleep will affect the development.
