According to a study by the World Health Organization, the growth rate of children and adolescents is not the same throughout the year. Children grow fastest in spring, especially from March to May, when they can grow 7.3 mm per month, and slowest in October, when they grow only 3.3 mm. Spring is the fastest growing season for children, which is probably due to the fact that children are exposed to sufficient infrared and ultraviolet radiation in spring, which accelerates blood circulation throughout the body and promotes the secretion of pituitary growth hormone, while bone cells also increase the synthesis of vitamin D in the skin, which promotes the absorption of calcium and phosphorus and facilitates bone growth and development. In spring, the human body has a strong metabolism, blood circulation is accelerated, respiratory and digestive functions are strengthened, and the secretion of endocrine hormones, especially growth hormone, increases, creating favorable conditions for children in the growth and development period. Therefore, in order for children to seize the golden season of growth, they should pay attention to nutrition, sleep, exercise and other aspects . Nutritional balance, a variety of nutrients intake is sufficient We emphasize that nutrition is even, a variety of nutrients intake, adequate and reasonable nutrition is the material basis to ensure the normal growth of children. Milk, seafood, meat, eggs, beans and a variety of fresh vegetables in the right amount of intake. But some puffed food. Barbecue and some chrysalis. Chicken and duck necks and other foods should be eaten as little as possible, otherwise they may lead to precocious maturity. Ensure that children get enough sleep Adequate sleep is beneficial for growing up, because growth hormone is secreted at the peak during deep sleep at night, and the longer the deep sleep time, the more growth hormone is secreted. 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 “children who can sleep grow up”. Generally speaking, 10-12 hours of sleep per day for children aged 3-6, 10 hours for elementary school students, 9-10 hours for junior high 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 secretion of growth hormone, it is best to let children fall asleep before 10 p.m. Moderate exercise, especially outdoor activities Spring is the season of vitality, so children should be allowed to get into the embrace of nature and enjoy the joy of sports. The right amount of exercise can stimulate the division and proliferation of epiphyseal cartilage cells in the long bones and stimulate the secretion of growth hormone, thus promoting growth. Three types of sports can help babies grow taller quickly. Scientific sports during adolescence can make height growth 4 to 10 cm, and a more graceful physique. Children can choose the kinds of sports that are easy to do and easy to stick to according to their interests. 1, aerobic exercise swimming, jogging, fast walking, skating, cycling, ball games and other aerobic sports. Through the large muscle groups involved in rhythmic repetitive motion, accelerate blood circulation, promote metabolism and growth hormone secretion. Aerobic exercise is best 3 to 5 times a week, 30 to 60 minutes each time, no more than 2 hours a day, can be divided into 2 to 3 times. 2, bouncing exercise human height is mainly determined by the length of the lower limb bones, jumping rope, jumping skin, frog jumping, longitudinal jumping touch high bouncing exercise, can make the lower limbs get rhythmic pressure, adequate blood supply will accelerate bone growth. Bouncing exercise to 1 to 3 times a day. Each time 5 to 10 minutes is appropriate. 3, stretching exercises pull-ups, rhythmic gymnastics, tai chi, kicking, leg press, ballet exercises and other stretching exercises can increase flexibility, making the body more relaxed and flexible. With the first two exercises, 3 to 5 times a week.
