A study by the World Health Organization confirms that children’s growth and development have significant seasonality, of which spring (March-May) grows fastest, and the growth rate of height is 2-2.5 times faster than that of autumn. Why spring baby height growth fast? 1, the baby can not grow taller without calcium as an element, and the absorption of calcium must have the assistance of vitamin D. In a year, spring sunlight in the ultraviolet content is the highest, sunbathing, accept ultraviolet radiation, is the most simple and important way to get vitamin D. Ultraviolet radiation allows the baby’s body D into vitamin D3, thus promoting the gastrointestinal tract to the absorption of calcium, so that the child’s bones grow better and faster. 2, spring human metabolism, blood circulation accelerated, whistle function, digestive function have significantly strengthened, growth hormone secretion increased, for the baby’s height growth to create a “golden condition”. Spring baby growth, these issues parents need to pay attention to a, adequate quality sleep Adequate sleep on the child’s height growth is beneficial, because the vast majority of growth hormone is secreted at night under the state of sleep, the longer the deep sleep, the amount of growth hormone secretion is more, and the child will grow taller. The secretion of children’s growth hormone has a certain law, one of which is: at 11:00 p.m. and 12:00 p.m., the growth hormone secretion is the most vigorous time, but it must be in the state of deep sleep, in order to play a role in a more efficient. Children from sleep to enter deep sleep generally need 45-60 minutes, then in order not to miss the 11 o’clock to start the growth hormone secretion peak, the child is best to go to sleep before 10 o’clock. Second, adequate nutrition Want children to grow tall, nutrition must keep up. To ensure a balanced intake of all types of nutrition for children. Protein, fat, vitamins, minerals, fiber, carbohydrates and water, seven nutrients are indispensable. Children eat a variety of daily diet, not partiality, not picky eating, intake of nutrients, in order to provide a more solid nutritional basis for the growth of height. 1, calcium calcium is the basis of bone growth, if the child’s intake of calcium can not meet the physiological needs of calcium, blood calcium and calcium in the soft tissues is insufficient, it must be to the bone “borrow calcium”, once the bone calcium, don’t affect the baby’s height growth. Spring children’s growth and development speed up, the demand for calcium increases, parents should give the baby more calcium-rich foods. 2, protein A variety of human tissues and organs are composed of protein, such as muscle tissue, internal organs, brain tissue, etc., and collagen, mucin is an organic component of bone. So, protein is not only the basis of the composition of life, or height growth of important nutrients. 3, vitamins Vitamin family members, although small, but the child’s growth and development has a pivotal role. For example, vitamins A and C can enhance the child’s resistance, while vitamin D helps calcium absorption, thus promoting the child’s height growth. 3, minerals two-thirds of the bones of minerals by calcium, magnesium, phosphorus three minerals, so these three minerals whether the content is sufficient for the elongation of the bones is very important. Iron, zinc and other minerals can also regulate the speed of growth and development of children from a lot of life activities, such as lack of zinc children have no appetite, nutritional intake is certainly not high; lack of iron will make the synthesis of hemoglobin is impeded, growth, intellectual development and immune function will be affected, so a reasonable intake of various types of minerals on the growth of the child’s height is also of great significance. Third, appropriate exercise Children often participate in physical exercise, can improve blood circulation, at the same time can stimulate the epiphyseal plate and bone, promote the secretion of growth hormone, so that the bone growth is more vigorous, so as to promote the growth of the child’s height. 1, jumping sports: touch high, jumping, jumping rope, basketball and so on. Jumping sports can pull muscles and ligaments and stimulate cartilage proliferation, which is very helpful to the growth of the bones of the crest and limbs. For example, jumping rope is a typical exercise to stimulate the epiphyseal plate and promote growth. A program of “15 minutes of jumping rope a day” will help your child grow taller through jumping. It is important to note that when children do jumping exercises, parents should teach children not to land on their heels, otherwise it is easy to cause injury to the knees and waist. 2, stretching exercises: pull-ups, swimming, stretching gymnastics and so on. Swimming as a most representative of the stretching movement can make all parts of the body are fully stretched and exercise; and pull-ups can stretch the crest, promote the growth of the crest bone, so that the children’s body continues to grow taller. School-age children should selectively carry out more stretching exercises, while infants and young children can do active or passive gymnastics, which can also stretch the body and promote the growth of height.
