When you meet a group of Northeast women on the street, you can't help but sigh at their height and aura, while when you travel in the south, you will find that the local women are relatively short and delicate in comparison. What is the reason for this difference in the height of women from the north and the south?
The relationship between height and genes
Many people believe that height is determined by genes, and different races have different height characteristics, such as white Europeans are generally taller than yellow Asians, black Africans are generally taller than white Europeans, and southerners are generally shorter than northerners, just because the genes of southerners are not as good as northerners. This view seems reasonable, but it is actually unscientific.
Genes only determine the upper and lower limits of height, not the specific number of heights. People of the same race basically fluctuate in a height range, rather than fixed at a height level. There are many factors that affect the specific value of height, such as nutrition, exercise, disease, hormones, etc., and these factors can have a positive or negative impact on height. Therefore, even people of the same race will have differences in height because of the difference in these factors.
Genes are mutable, not immutable. Genes are affected by the environment, such as temperature, humidity, food, viruses, etc., which will affect genes, resulting in gene mutations. Therefore, even people of the same race will have genetic mutations due to changes in the environment, which will affect their height.
Genes can be communicated, not isolated. Genes are transmitted through reproduction, and the exchange of genes between different races, through marriage, immigration, war, etc., leads to the mixing of genes. Therefore, even people of the same race will be mixed because of the exchange of genes, which will affect the height.
The relationship between height and the environment
In addition to genes, the environment is also an important factor in determining height. The environment mainly includes two aspects: the natural environment and the social environment. The natural environment mainly refers to the climate, topography, vegetation, etc., and the social environment mainly refers to the economy, culture, education, etc. These environmental factors can have a direct or indirect impact on height.
The influence of the natural environment on height is mainly reflected in two aspects, one is temperature, and the other is food. The effect of temperature on height is mainly achieved by affecting metabolism and the secretion of growth hormone. In general, low temperatures slow down metabolism and prolong the growth cycle, which is conducive to height growth. High temperatures will accelerate metabolism and shorten the growth cycle, which is not conducive to height growth.
The effect of food on height is mainly achieved by providing nutrients. Generally speaking, foods rich in protein, calcium, phosphorus and other elements are good for the development of bones and muscles, and are conducive to the growth of height. Foods lacking these elements can lead to stunted development of bones and muscles, which is not conducive to height growth.
The influence of social environment on height is mainly reflected in two aspects, one is economy, and the other is culture. The impact of the economy on height is mainly achieved by affecting the standard of living and medical conditions. Generally speaking, economically developed areas with a high standard of living and good medical conditions are conducive to the growth of height. Economically backward areas, low living standards, and poor medical conditions are not conducive to the growth of height. The influence of culture on height is mainly achieved by influencing values and lifestyles. In general, a culture that values physical health and exercise is conducive to height growth. Ignoring a culture of physical health and exercise is not conducive to the growth of height.
Relationship between height and other factors
The influence of psychological factors on height is mainly achieved by influencing mood and stress. In general, mood and stress affect the body's endocrine system, which affects the secretion and action of growth hormone. Growth hormone is an important factor in promoting height growth, and if the secretion and action of growth hormone are disturbed, it will affect height growth.
The influence of social factors on height is mainly achieved by influencing social status and social expectations. Generally speaking, social status and social expectations affect people's perception and evaluation of their height, which in turn affects people's satisfaction and pursuit of their height. Social status and social expectations are determined by social norms and values, and different societies attach different importance to height and prefer the direction.
For example, some societies believe that height is an advantage, a symbol of power, and a standard of beauty, so people will have higher expectations for height, will pursue higher height, and will be dissatisfied with their height, so they will take some measures to increase their height, such as wearing high heels, doing stretching exercises, taking drugs, and so on.
The influence of personal factors on height is mainly achieved by influencing the individual's choices and behaviors. In general, an individual's choices and behaviors affect an individual's physical condition and lifestyle habits, which in turn affects the growth of height. Individual choices and behaviors are determined by personal will and preferences, and different individuals have different perceptions and attitudes towards height.
Some people think that height is an insignificant attribute, a way of self-acceptance, and a kind of happiness that has nothing to do with height, so they will choose and do things that have nothing to do with height growth, such as eating their favorite food, doing their favorite exercise, sleeping their favorite sleep, and so on.
epilogue
Through the above analysis, we can see that the difference in the height of women in the north and south is the result of a combination of factors, rather than the result of a single factor. Therefore, we cannot simply use a standard to measure the height of women in the north and south, but respect their individuality and diversity, and appreciate their beauty and charm.
