Spring is the fastest growing season for children’s height. In spring, with sufficient sunshine and spring flowers, children’s whole body blood circulation is accelerated, which also promotes the secretion of pituitary growth hormone, while bone cells also benefit bone growth and development due to increased skin synthesis of vitamin D, which promotes calcium and phosphorus absorption. How to seize the powerful time to promote children’s growth? First of all, pay attention to a balanced diet, after entering the spring children grow and develop faster, the demand for various nutrients also relatively increased, parents should ensure adequate energy and quality protein intake including rice and noodles staple food, milk and milk products, eggs, fish and shrimp, chicken and duck, as well as a variety of fresh vegetables, fruits and vegetables in a reasonable mix. And sweets, carbonated drinks, coffee, fried food, etc. should be limited. At the same time, ensure that children get enough sleep, because growth hormone has a peak secretion period after 12:00 midnight, and it is not easy to reach the peak period under light sleep condition. Exercise is also an important factor in promoting children’s growth. When spring is in full bloom, let children get into the arms of nature, run and jump to promote bone development.
