Today is a society that blindly compares with others. Wealth and appearance are the main goals. However, more and more people have discovered that height has a lot to do with finding a partner, income and other aspects. Therefore, height has gradually become a sensitive word. Today, the editor will take you to look at the height ranking list of Chinese women and see how tall Chinese girls are. The most authoritative data at present is the 2015 statistics that the height of men is 167.1cm and that of women is 155.8cm. Other online reports of men over 170cm and women over 160cm are mainly young people in big cities (around 20 years old). Generally, centimeters (cm) are used as units, but meters (m) are also more commonly used. Height refers to the length of the vertical part of the body, which is derived from the vertical growth and development of the body and is greatly influenced by genetic factors. Girls start to grow taller earlier than boys, with a rapid growth phase at 12-13 years old, and growth stops at 19-23 years old. Boys start to grow taller later, with a rapid growth phase at 15-16 years old, and growth stops at 20-25 years old. When the long bones of the limbs and the spine have completed ossification, their height stops growing. There are many factors that affect height, such as genetic inheritance, nutrition, sports competition, environment, lifestyle, ethnicity, endocrine system, early or late estrus (the average height of menarche at the age of 18 is 5 cm higher than that at the age of 11), close relative marriage, medical development, etc. The material condition of human height is bones. The three parts related to height are mainly the head, spine and long bones of lower limbs. Experts remind us that human growth and development is a relatively complex process, which proceeds from top to bottom and from near to far. At the beginning of head growth and development, when a newborn baby is born, the length of its head is 1/2 of that of an adult's head, and the length of a newborn baby's head is 1/4 of its body length. In comparison, the growth and development of the lower limbs is slow, and when a newborn is born, its size is only 1/4 of that of an adult. Therefore, the growth and development of the long bones of the lower limbs after birth has a greater impact on height. The changes in the growth and development proportions of various parts of the human body from baby development to adult development. Generally speaking, under normal circumstances, the body length of a person is about 50 cm when he is born; within 1 year old, it undergoes the first leap in height growth, and can grow to about 75 cm; when he is over 2 years old, it reaches about 85 cm; and when he is over 3 to 7 years old, he increases by 6 to 15 cm each year. Most people will grow to 155-160 cm tall by the time they are 11-12 years old. During this period, the height difference of most people was not very big. As everyone knows, with the onset of puberty, height, like all organs of the body, undergoes another leap. Various factors such as genetic factors, health status and physical exercise make the height of human body vary greatly from person to person. During this period, many people can grow 6 to 7 centimeters per year, or even 10 to 13 centimeters. When children are in middle school, their height growth is quite rapid. Usually within one or two years, an innocent and immature boy will grow into a strong boy or a graceful and pure girl. After the age of 17 to 18, the growth rate of height slows down significantly until the time of estrus, which is when girls are 18 to 23 years old and boys are 22 to 25 years old. At this time, a person's height is basically fixed. |
