During the winter and spring, there are usually a lot of children who come to the hospital for treatment of colds, but recently there have been a lot of children who have trouble sleeping, from a few months old “hairy head” to kindergarten students. Ms. Li’s one-year-old child is one of them, he has always slept well at night, but in the last week or two, sleep is very bad. The child has to wake up every hour, and then keep turning his body. At first, Ms. Li thought the child was hungry, but gave him milk, he did not eat. Because of the fear of the child tossing and turning and catching a cold, she had to get up every time to re-cover the child. ”To the hospital to see the child because of calcium deficiency.” Ms. Li said that after the doctor’s massage and conditioning, that night was much better, and then for the child to supplement some calcium, so that the child try to have a good sleep. Children sleep poorly, generally caused by calcium deficiency, poor digestion or frightened of these reasons. Especially calcium deficiency will not only make the child sleep poorly, but also hair loss, which can cause rickets in serious cases. “This time because of calcium deficiency caused by poor sleep children more, and the season also has a certain relationship.” People generally do not sleep as well in spring as they do in autumn and winter, plus the sun has been out less recently, the body’s absorption of calcium is relatively poor. For children who do not sleep well, Sun Bo suggested that parents can knead the small Tianxin (or fish intersection, located at the root of the palm of the hand, where the large and small fish intersection) and Baihui points (located in the head, the two ear tip line at the midpoint), both of which have a calming effect. Because of calcium deficiency caused by poor sleep, in addition to kneading acupuncture point conditioning, but also need to be appropriate calcium supplementation, “you can take calcium gluconate, calcium lactate or calcium carbonate, from the actual effect, calcium carbonate is the best, followed by calcium lactate, calcium gluconate and then a little worse.” The calcium supplementation should be combined with the taking of Iconocin cod liver oil, “calcium supplementation must be taken together with vitamins, otherwise it is not effective. In addition, the usual diet can also eat more calcium-rich food, such as fish, bone broth and so on.” The key is still to let children go outdoors more often and get more sunlight, so as to promote calcium absorption and help healthy bone development. “Many children are deficient in calcium, and too little outdoor exercise has a lot to do with it.”
