Children grow the fastest in spring, according to a study by the World Health Organization, which showed that children and adolescents do not grow at the same rate throughout the year, and that children grow the fastest in spring. Why is the spring season good for growing taller? In nature, various biological laws are spring, summer growth, autumn harvest, winter storage”, that is to say, spring is the season of growth of all things, humans are no exception, will also change with the change of the seasons, this is the theory of Chinese medicine “the unity of heaven and man”. Modern scientific research proves that the human metabolism is strong in spring, blood circulation is accelerated, respiratory and digestive functions are strengthened, endocrine hormones, especially growth hormone secretion increases, children are in the growth and development period, so spring is the golden season for children to grow. In addition, the UV content of the sun in spring is the highest of all seasons. UV light is also beneficial to the growth and development of bones because vitamin D in food or in human skin tissue can only be absorbed by the body after being transformed into vitamin D3 by UV light irradiation, and then into biologically active hydroxylated vitamin D in the liver and kidneys, which can promote the absorption of calcium and phosphorus in the gastrointestinal tract and reduce their secretion through the kidney tubules, providing sufficient calcium and phosphorus for the growth and development of bones. The latter promotes the absorption of calcium and phosphorus in the gastrointestinal tract, reduces their excretion through the renal tubules, and provides sufficient calcium and phosphorus for bone growth and development. These are the intrinsic factors for children’s growth in spring, but parents must pay attention to comprehensive conditioning and strong care in order to seize the golden season of children’s growth, so that they can grow healthy and reach their ideal height. What factors affect the growth of children? The first is nutrition Protein is an important nutrient for height growth, so it is important to ensure an adequate supply of high quality protein, milk, eggs, fish, all kinds of meat and other animal proteins are good for growth. The right amount of fat is also essential because fat-soluble vitamins like vitamin A and D, which promote the absorption and utilization of calcium and phosphorus, must be absorbed by the dissolution of fat. Staple food is essential because the energy of human activities mainly depends on glucose to supply, if the staple food is eaten too little, insufficient supply of glucose will consume protein, which will also affect the growth, but also appropriate to eat some beans, a variety of coarse grains, nuts, fresh vegetables, fruits, if necessary to supplement calcium, iron, zinc and other minerals to avoid nutrient deficiencies. In short, rich food, good and reasonable nutrition is a necessary condition to ensure the normal growth of children. Secondly, sleep Adequate sleep is very important for growth because, during the growth period, human beings need enough growth hormone to grow taller, and growth hormone is secreted at the peak during deep sleep at night. If a child’s nighttime sleep is affected for various reasons, it will directly affect the secretion of growth hormone. This is the reason why dolls who can sleep grow taller. Generally speaking, 10-12 hours of sleep per day for children aged 3-6, 10 hours for elementary school students, 9-10 hours for middle school students, and 8-9 hours for high school students is very beneficial to ensure normal growth. In order to enter deep sleep as soon as possible and reach the peak of growth hormone secretion, it is best to let children fall asleep before 22:00. The natural physiological phenomenon of spring sleepiness and autumn fatigue, in fact, is very beneficial to human body growth, and many children in order to complete homework or participate in various study classes, can not sleep on time and ensure adequate sleep, long-term in this state, will affect the growth of children. The third is moderate exercise moderate exercise can stimulate the division and proliferation of long bone epiphyseal chondrocytes, and stimulate the secretion of growth hormone, thus promoting growth, regular exercise is also conducive to bone calcium and phosphorus metabolism, accelerate the mineral bone deposition, so that bone density increases, and promote growth and development. Infants and toddlers can do active or passive gymnastics, school-age children can do upward jumping exercises such as running, jumping rope, throwing basketball, etc.. You can also do some pull-up exercises, plate bar, push-ups, sit-ups, etc. Be careful not to overload the exercise for a long time, so as not to cause cartilage damage, muscle strain, which is not conducive to normal growth and development. Spring is the season of vitality, so you should let your child get into the embrace of nature and enjoy the joy of sports. Fourthly, children who lack love and care from their families will have less release of growth hormone from the hypothalamus, resulting in insufficient secretion of growth hormone, which will also affect their growth and development. At the same time, the lack of love and care for the child, psychological depression, personality more withdrawn, and less interaction with other children, exercise will also be insufficient, less exercise stimulation, growth hormone secretion will also be reduced, all will affect the child’s height. So whether it’s the child’s physical or mental health, it’s important for parents to increase the care for their children. The fifth is genetic Some people say that the parents’ height determines the child’s height, it should be said that there are certain factors, but not absolute, if there is no hereditary disease, the child’s height is mainly determined by the first three conditions, we can look at the modern Japanese youth, the original we say small Japan, that is because the original Japanese diet structure is not reasonable, the intake of sugar food is too high, the last fifty years Japan gradually adjust the children Diet structure, to strengthen the intake of protein, so the average height of modern Japanese youth is basically not lower than the level of our youth. The average height of modern teenagers in China is generally higher than that of their parents, which also proves that the nutritional status plays a decisive role in the height of children.
