My daughter is in the first grade of primary school from birth to now, and she belongs to the taller children of the same age, so I have never worried about her future growth. It was not until I heard my sister complain that I found that many parents in life were worried about their children's height.

My sister said that the two little twin nephews were hardly long in other seasons except spring, which surprised me. So I asked other parents and checked some information before I found out that children really don't grow every day, but like flowers and trees, spring is their peak growth.

The World Health Organization has done a study, which confirmed that children in the growth and development period have obvious seasonality, in which the growth rate of height is particularly fast from March to May (spring) every year, and the growth rate of height is 2-2.5 times that of other seasons. Therefore, it is not a strange thing that children grow up quickly in spring, but a common phenomenon with scientific basis.

Maybe many parents don't understand the above phenomenon like me. Actually, it's not a strange phenomenon when you think about it carefully.

As we all know, the indispensable trace element for children's growth is "calcium", and the absorption of calcium must be coordinated with vitamin D. Although there are ultraviolet rays every day all year round, the intensity of ultraviolet rays is different every day. The ultraviolet intensity was the weakest in June, 5438+February, and reached the peak in July.

From March every year, the intensity of ultraviolet rays gradually increases, reaching 90% of that in midsummer in March and April, especially from 10: 00 to 15: 00. Although ultraviolet rays can make people's skin black and wrinkle, and even cause other diseases, most of the vitamin D needed by the human body comes from the sun, especially the growing children, who need proper ultraviolet irradiation in spring.

Proper ultraviolet irradiation can help children synthesize vitamin D and promote the absorption of calcium in children's gastrointestinal tract, thus promoting the absorption and utilization of calcium and phosphorus by the body, and making children grow taller and faster by using bone development.

Scientific research shows that growth hormone can promote the growth of bones, viscera and the whole body, promote the synthesis of protein, affect the metabolism of fat and minerals, and play a key role in human growth and development. A large number of short children are caused by growth hormone deficiency or partial growth hormone deficiency.

Throughout the year, the physiological changes of human body are different with different climate and temperature. When the human body enters the spring with moderate temperature from the cold winter, the tiny blood vessels in the skin and muscles are also quietly changing from the contracted state to the relaxed state, which leads to the acceleration of blood circulation in the pituitary gland, the increase of pituitary growth hormone secretion and the growth of children's height.

With the coming of spring and the warmer weather, parents prefer to take their children out for an outing. Compared with hot summer and cold winter, children spend more time outdoors. Appropriate activities can not only promote the development of bones, but also promote blood circulation and accelerate metabolism. Strong metabolism will stimulate endocrine and secretion of hormones, especially the secretion of growth hormone, and the height of children will naturally soar.

To sum up, there is a scientific basis for the two little nephews to grow taller only in spring, but if the children grow taller only in spring and hardly in other seasons, this is not a good phenomenon, because it turns out that the children grow taller or not. The key is whether you have the conditions to grow up. Although spring is the golden age for children's growth, if parents do not pay attention to tapping the advantages of spring and give full play to the conditions for promoting children's growth in spring, it is difficult for children to grow up in spring and reach the height level of ordinary children.

1) Proper exercise

Proper exercise can not only improve blood circulation, but also stimulate the development of epiphysis and bones, promote the secretion of growth hormone, and thus promote the growth of children. For example, appropriate jumping, stretching, skipping, running, playing basketball, pull-ups, swimming, stretching gymnastics and so on. Can promote bone growth and achieve the goal of growing taller.

I am convinced of this, because I suffered from lack of exercise when I was a child. My sister and I share the same genes. There is almost no difference between nutrition intake and sleep time when I was a child. But when I was a child, my sister was lively and active, and I liked quiet. If you don't go out, you won't go out. Even physical education class at school is dragging his feet. As a result, my sister grew to 173cm when she was in high school, and I'm only 160cm now.

2) get enough sleep

Adequate sleep can not only promote the secretion of growth hormone by pituitary gland, promote the height of children, but also improve the brain power of children.

It is found that the concentration of human endocrine growth hormone in a day is not average to every time point, but has its day and night law, that is, it is secreted relatively less during the day and more after sleeping late at night, especially after sleeping late at night. The "burden reduction order" also clearly requires the sleep time of students in the growth and development period: primary school students sleep no less than 10 hours a day. And to ensure that children can sleep 10 hours, parents should at least let their children fall asleep before 9: 30 in the evening.

3) Balanced and rich nutrition intake

Regarding the influence of diet and nutrition on children's height, Japanese scientists did an experiment: in the experiment, scientists divided six groups of twin children into two groups, one group only provided nutrition necessary for children's growth, and the other group added lysine to promote human growth and development. After 13200 hours of experiments, scientists found that the height of the group providing lysine was significantly higher than that of the other group 1.7cm on average.

In fact, the experimental results can also be confirmed by twins of different heights around us. Usually, shorter twins are more picky about food. For example, my sister's two little nephews are obviously picky eaters.

If you want your child to grow taller, nutrition must keep up. Protein, fat, cellulose, carbohydrates, water, vitamins and minerals are all indispensable. As parents, it is the responsibility to provide children with a variety of diets and ensure that children consume balanced and rich nutrition.

Of course, not many parents can do this, because grandparents who take care of the baby don't know how to do it, while young parents know it, but they don't have time to do it. Just like my sister's in-laws, since the two little nephews began to eat complementary food, four or five kinds of dishes, such as shredded potatoes, egg soup, stewed chicken with potatoes and fried yam slices, have been switched back and forth, so now every time someone asks two children what they want to eat, they will subconsciously choose one of the above meals.

If you are also a single mother who cooks, then I recommend you to read this cookbook to make your child grow taller. This book was started when my daughter added complementary food for six months. At that time, I didn't buy this book to help her grow taller, but with the mentality of starting more sets of complementary food books, so I could make complementary food for my daughter in another way.

At present, my daughter is 6 years old and less than 7 months old, and her height is 132cm. She is of middle age among children of the same age, even more than half of her twin brother who is 10 months older than her. Apart from heredity, sleep and exercise, I believe this complementary food book is the reason why she is so much taller than her peers.

In fact, there are a lot of increased ingredients in daily life, but parents have limited knowledge and don't know it. By reading this book, we will find that there are as many as 38 kinds of common heightening ingredients in life, and these 38 kinds of ingredients can make 193 nutritious and delicious balanced heightening recipes.

193 long and high recipes, each with an intuitive video teaching, even parents in the kitchen can follow the video and easily fix it. 193 delicious dishes are enough for children to eat in different ways 365 days a year.

In addition, the book also introduces in detail the common sense and exercise guide of the three golden periods of children's growth and height, including infancy, preschool and adolescence, and teaches parents how to promote their children's growth and height more efficiently from three aspects: sleep, exercise and nutrition.

The original price of a book is 36 yuan, but now the activity price is only 29.8 yuan, and the cost of a takeaway meal is less than 12 years old, which can help children cultivate the habit of being picky about food and give full play to their height advantage.
