Baby height:
1, not picky eaters
There are two peak periods in the process of people's growth and height: one is infancy, and the other is adolescence, during which promoting growth and height nutrition is the foundation. Children should eat more foods rich in various nutrients, such as animal foods such as bean products, eggs, fish and shrimp, milk and lean meat, vegetables and fruits rich in vitamins C and A and inorganic salts such as calcium, especially calcium, and add appropriate amounts of calcium and cod liver oil to young children and school-age children, which is very beneficial to long people.
2. Ensure adequate sleep
Bodybuilding experts often say that "children sleep well and grow tall". Scientists have found that the peak of growth hormone secretion occurs when children sleep-after 10 pm and lasts for a long time. If you want your child to grow up, you must go to bed before ten o'clock in the evening. Adequate sleep is an important way to promote the baby's growth.
3. Multi-choice is beneficial to long-term exercise
Children's activities should choose projects that are relaxed, lively, free to stretch and open, such as swimming, dancing, badminton, table tennis and horizontal bar. And those heavy, contractive or compressive sports, such as weightlifting, lifting dumbbells, tensioners, wrestling, long-distance running, etc., are not good for height growth.
Why do northerners grow so tall? The first reason is the climate. Compared with the warm zone, the cold zone can stimulate human growth hormone, and people will eat more food because of the cold weather, so it is easy to grow taller. Therefore, people in cold regions such as Russia and Yugoslavia are generally very tall, and the north of our country is no exception.
The second is the diet structure. In the south, rice and pork are almost absolute staple foods, while in the north, most people are used to eating pasta, beef and mutton, which has different effects on the growth of bones and body shape.
However, these are not absolute. In recent years, the average height of Japanese teenagers has increased rapidly. According to statistics, the average height of Japanese teenagers has surpassed that of our country, which is very unpleasant ~
There is also the higher the latitude (north), the farther away from the equator, the colder the weather, people need to reduce the unit energy loss and must increase the body surface area, so northerners are taller. On the contrary, southerners, who are close to the equator and have hot weather, have to reduce their body surface area, so they are shorter. Just as the Northeast Tiger is much bigger than the South China Tiger, it is the same reason.
My son asked why northerners are so tall, which is actually an interesting physical topic, not all biological topics.
One of the great functions of human panels is to dissipate heat. People live in the tropics and dissipate heat less in the cold zone, which will help warm-blooded animals adjust its body temperature.
A cube with a side length of 1 and a surface area of 6. If the volume is doubled, its surface area is 9.5, instead of doubling, it becomes 12.
Similarly, if a person's volume is doubled (that is, his weight and fever are doubled), the surface area of the panel is only 1.5 times instead of the original 2 quilts, so that a big man's body heat is twice as large as the original, but his heat dissipation capacity is only expanded to 1.5 times. So the big man in the cold zone helps to keep warm, and the small man in the tropical zone helps to dissipate heat.
For a small animal like a mouse, the panel area is very large relative to the volume (weight and heat dissipation), so this animal should keep moving and eating, which will help keep its body warm.
The country with the highest per capita height in the world is Iceland (182 cm), because it is very cold near the North Pole.
In the south, people close to the equator are all short and black people, and adults around 140 are very common.
In daily life, fat people are always afraid of heat, and thin people are always afraid of cold, which is the reason why their weight and body surface area ratio are different. Everyone is trying to adapt to the natural environment and help them survive.
Duan Shoushen replied: Why are northerners so tall? Duan Shoushen replied: Why are northerners so tall?
A Chongqing girl asked why northerners are so tall.
God replied:
The snow in the north is more than one meter. If it grows short, it will be submerged by snow ...
A Chongqing girl asked why northerners are so tall, and there is a big difference in body shape between northerners and southerners.
There are great differences in the body shape of people in different regions, especially in the northern and southern regions. For example, the maximum height of men in Shandong, Beijing, Tianjin, Inner Mongolia and Liaoning provinces (autonomous regions and municipalities directly under the Central Government) is above 17 1 cm, while the maximum height in Yunnan, Guangxi, Guizhou and Hainan provinces (autonomous regions) is below 168 cm. Weight and chest circumference also show the same characteristics. The maximum differences of male indicators among provinces (autonomous regions and municipalities directly under the Central Government) are: height 5.6 cm, weight11.2 kg, and chest circumference 8.3 cm; Female: height 4.7 cm, weight 9.6 kg, bust 7.2 cm.
There are obvious regional differences in cardiopulmonary function of adults. In Shandong, Jiangsu, Beijing, Inner Mongolia and other provinces (autonomous regions and municipalities directly under the Central Government), the maximum lung capacity of men aged 20-24 is over 4000 ml, while that of men in Qinghai, Guangxi, Hainan, Guizhou and other provinces (autonomous regions) is below 3500 ml, with the maximum difference of 1227 ml; The maximum lung capacity of women in Shandong, Tianjin, Beijing and Jiangsu provinces (municipalities directly under the Central Government) is more than 2800 ml, while the maximum lung capacity of women in Qinghai, Hainan and Guizhou provinces is less than 2400 ml, with the maximum difference of 885 ml.
1. The Qin and Han Dynasties were the first stage: in 36 BC, the western regions of the Western Han Dynasty all protected Gan Yanshou and Chen Tang, a deputy captain, and led 40,000 soldiers to the western expedition to the Xiongnu in Zhizhi City (Jiangbulin City, Kazakhstan) ... On the way to the battle, the soldiers of the Western Han Dynasty noticed a very strange mercenary under Khan, who had a high nose and deep eyes, red hair and green eyes, and a burly figure, and formed a phalanx during the battle. In the battle of Zhi City, the Han army won a total victory, beheading 15 18 people, taking 145 people alive and surrendering 1000 people. Gan Yanshou and Chen Shang brought these prisoners back to China. And put these Romans into the army, in Gansu, and set up a county called "li gan". A record in the Book of the Later Han Dynasty: "li gan County was established in the early Han Dynasty, and the country name was taken as the county." "li gan" was exactly what China called Rome at that time. Since it is a "county named after the country", this new county must have been set up to accommodate the Romans. This Roman army became the first European nation to be assimilated.
2. The Wei and Jin Dynasties were the second stage: The Book of Jin and Shi Shuo Xin Yu recorded East Jin Mingdi as "yellow beard" and "yellow head", which is a typical Caucasian ethnic feature. He also called it "Xianbei slave" and his mother "Yan Dynasty" (now Beijing area), saying that it was similar to his mother's appearance. It can be seen that the Xianbei tribes at that time, and even the locals in North China, contained a large number of Caucasian ethnic components.
In the Western Jin Dynasty, the nobles of the Western Jin Dynasty used to kidnap and buy local women from the Liaohe River basin to be wives and concubines, mainly in pursuit of strangeness, because local women and the Han nationality looked different, with yellow hair and blue eyes, and then Mohe nationality appeared. Logically, it can be concluded that a small number of ancient Finns may have gone to Northeast Asia. As we all know, Finns are Nordic people with tall and powerful physique, and they are Xianbei (white Xiongnu) in Northeast China.
3. The period of Sui, Tang and Five Dynasties is the third stage: The History of the New Five Dynasties, The Appendix of Siyi and the Biography of Shiwei in the Book of the Old Tang Dynasty and the Book of the New Tang Dynasty all recorded that there were "yellow-headed Shiwei", also known as "yellow-headed Shiwei", and Shiwei was the predecessor of Mongolian ministries.
The Book of the New Tang Dynasty 1 10 Biography of Li Duozuo records that "Li Duozuo, who was first the chief of the cymbals, was named' the chief of the yellow head', and later entered China, his lineage was far away", indicating that there were also tribes with yellow hair and blue eyes among the cymbals in the Tang Dynasty.
During this period, the nomadic people in the north and the Aryan people in Europe further intermarried and formed a brand-new ethnic composition, which laid the foundation stone for the rise of Khitan, Jurchen and Mongolia in the future. In the poem Yongjiaxing written by Zhang Ji, a poet in the Tang Dynasty, it is recorded that "Huang Tou Xianbei entered Luoyang" is evidenced by poems.
4. The Liao, Jin and Yuan Dynasties were the fourth stage: The Compilation of the Three Dynasties North League Association recorded a jurchen who had "yellow hair, yellow temples and green eyes, and was called' yellow-headed jurchen'"; The article "Huang-headed Nuzhen" in the Story of the Song and Mo called it "yellow hair and green eyes"; The article "Yellow-headed Nuzhen" in the Records of the Kingdom of Khitan and Miscellaneous Notes of Various Fanguo recorded that her facial features are "yellow hair and green eyes", which is obviously a Caucasian ethnic feature. This proves that people of all ethnic groups in Northeast China have more or less Caucasian genes. Genghis Khan and his father should also have blue eyes soon, and their clan name "Bo Er Jin" means "blue eyes".
5. The fifth stage is the end of the Yuan Dynasty and the beginning of the Ming Dynasty: when Mongolia made the Western Expedition, it conquered the Azoos in the Caucasus. Azoos originally believed in the Orthodox Church. They were tall, with white faces and blue or green eyes. Later, they joined the army and entered the Central Plains to form the Azoos Army, which was called "Green Eyes Hui". Semu people and Mongolian ancients were aristocrats at that time, and Han people with low status had no right to intermarry with aristocrats. Later, Kublai Khan of Yuan Shizu ordered various garrison troops to "organize people everywhere and make up people, etc.". Most of these troops were stationed in the north, so the descendants of these early European immigrants were mainly assimilated by Mongols, Xixia people and Jurchen, forming the northerners in the future.
6. The period of the Qing Dynasty and the Republic of China was the sixth stage: Tsarist Russia pursued the policy of "Russianization of Border Areas" in Siberia and the Far East, which caused sporadic immigrants from as many as 2/kloc-0 countries to flow into Siberia and the Far East. Most of these immigrants were Russians, followed by Ukrainians, Tatars, Finns, Poles and Caucasians. From/kloc-0 to September, 689, the Sino-Russian border line with the Ergun River as the boundary came into being after China and Russia signed the Treaty of Nebuchadnezzar. Article 5 of the treaty stipulates that "all Russians in our country and all Russians in our country have remained as before and need not be repatriated." This has resulted in the historical phenomenon that there are Russian residents in China and Russian residents in China.
/kloc-at the end of 0/9 century, with the rise of gold mining on both sides of the Ergun River, many mainlanders from Shandong, Hebei and other provinces were recruited as gold miners by Russian capitalists. 1900 years ago, when the Middle East railway was under construction, more Chinese laborers were attracted to the mainland. Some of them later flowed into Russia's border areas to engage in gold mining, and some worked as employees for Russian officials and rich peasants. Because most of these Chinese laborers were single young people, they lived among Russians, and they became friends with Russian girls for a long time, and then they fell in love and became married, forming mixed nationality families, but their children could not.
Conclusion: People of all ethnic groups in the north have been intermarried with European ethnic groups for thousands of years, so they inherited the tall physique of Caucasian ethnic groups from the genetic point of view. Similarly, most people with type A blood in the north and type B blood in the south also prove this point.
Why do northerners grow tall and have large latitudes? Because the growth cycle is long and the development is late in cold areas.
Therefore, it is relatively strong and as high as some, which is true of any biological species.
However, in China, civilization and etiquette in low latitudes are more advanced than in high latitudes. This is not the case in other parts of the world, on the contrary.
It is said that the water vapor over the Indian Ocean was blocked by the Himalayas in the process of going northward, which made the river network forest dense in this part of the south.
Why are northerners so tall and strong? The environment in the north is worse than that in the south, which is on the one hand; In terms of diet, there are also differences between the north and the south. Southerners' staple food is rice, while northerners like pasta. Southerners have a light taste and like to drink tea, while northerners have a heavy taste, heavy salt and like to drink spirits. The weather in the south is warmer, such as snowstorm, which is rare, but it is different in the north. The cold winter is windy and freezing. Under the influence of this series of geographical factors and human environment, rough northerners and delicate southerners have been created.
Are all northerners strong? Of course, but all the legs are muscular.
The view that northerners are taller in everything 1:
Mainly because of the climate and diet. Southerners are no less hairy than those in the north. The difference in climate makes the plants and animals in the north grow tall. For example, plants such as cabbage, radish, eggplant, tomato, watermelon and wax gourd, and poultry such as pigs and cattle are much fatter than those in the south.
For Americans, northerners in China are taller than southerners. Nordic people are taller than southern Europe and the largest race in the world.
It's mainly about latitude.
The higher the latitude (north), the farther away from the equator, the colder the weather. People need to reduce the unit energy loss and must increase the body surface area, so northerners are taller. On the contrary, southerners, who are close to the equator and have hot weather, have to reduce their body surface area, so they are shorter.

Why are northerners so tall? Please, thank you. First, it is due to the climate. The cold zone can stimulate human growth hormone more than the warm zone, and because of the cold weather, people will eat more food, and of course it is easier to grow taller. Therefore, people in cold regions such as Russia and Yugoslavia are generally very tall, and the north of our country is no exception. The second is the diet structure. In the south, rice and pork are almost absolute staple foods, while in the north, most people are used to eating pasta, beef and mutton, which has different effects on the growth of bones and body shape.
