Can psychological factors also affect growth? In recent years, there are 1.1 million couples divorcing each year, with an average annual increase of 4.4% from 1991 to 1999, and some children are affected by domestic violence, abuse, drinking, smoking, drug use, “two families”, separation, second career, threat of unemployment, high expectations, unfair distribution The child feels the pain of the conflict due to domestic violence, abuse, drinking, smoking, drug use, “two families”, separation, second job, threat of unemployment, high expectations, unfair distribution, extramarital relationship, overcrowding, lack of necessary health knowledge, value clash, and “psychological violence” such as verbal abuse, ridicule, mockery, and discrimination. This causes children to feel the pain of conflict, thus reducing the secretion of growth hormone in their bodies, and their height is shorter than that of children who are cared for in a harmonious environment. The lack of mother’s love and care can affect a child’s height. The lack of maternal love in children affects their height. There are individual differences in height for each person, but they are mostly related to genetic, nutritional and endocrine factors, which have been known for a long time. However, some experts have found that emotional disorders can also affect height. If a child grows up in an environment that lacks family warmth and adequate maternal love, his height is often shorter than that of children of the same age, which is known abroad as emotional overshadowing short stature disorder, or “emotional overshadowing syndrome”. The main reason why lack of maternal love affects the height of children with emotional overshadowing short stature syndrome is that the hypothalamus and pituitary system are emotionally suppressed, which in turn causes a decrease in the secretion of growth hormone from the pituitary gland. In addition to shorter height, children with this disorder also have abnormal behaviors such as delayed intellectual development, excessive drinking, excessive eating, soliloquy, hyperactivity, and incompatibility in interpersonal relationships. Children with emotional masking generally have unstable sleep, lack of security, and sometimes wake up screaming and crying in their dreams, etc. These conditions can affect the quality of sleep. Children’s growth hormone, hormone, is only secreted in the deep sleep period and the mature sleep period. Therefore, it is said that children who have restless sleep and wake up easily may have a great inhibition of this growth hormone secretion, which is one of the important reasons why children cannot grow taller. Foreign studies have also found that once these children are relieved of negative psychological factors, a significant proportion of them are able to grow rapidly to catch up and reach the height of normal children. According to a recently published study in the UK, children who live with parents who fight a lot, or who come from broken homes, are more likely to be shorter in height. To assess the adverse effects of family conflict, researchers examined health problem visit reports and found that at least 300 children came from difficult families caused by family tension, parental divorce, single parenting or parental abandonment, which accounted for 4.5 percent of the total number of children surveyed. The researchers’ analysis found that 31.7 percent of children who experienced family conflict were short in stature, compared to 20.2 percent of children who had no such experience. Combined with other factors known to influence growth, such as social class, family size and gender differences, the corresponding percentage of differences was only slightly lower. Does stress and anxiety affect girls’ height? According to a recent report by Daniel Pace, a child psychologist at the New York State Psychological Institute, girls who live with stress and anxiety all day are shorter than girls with happy and stable emotions. The report was presented to 716 children from 9 – 18 years old to do a 9-year follow-up study. Girls who felt nervous were 5.08 centimeters shorter than those who felt happy and were more than twice as likely not to be 1.57 meters tall or taller. Psychologists speculate that emotions may inhibit the normal production of growth hormone, which governs height. The study also found that stress did not appear to cause short stature in boys. This may be related to the fact that boys and girls have different physiological responses to stress. However, further research is needed to confirm whether this is the exact mechanism. One type of stress and anxiety that may affect height growth is “separation stress,” which means that some girls panic about being separated from their parents, such as not wanting to go to school and not sleeping in separate rooms from their parents. The other is “chronic tension and anxiety disorder,” which is characterized by a timid temperament, lack of self-confidence, fear that other children do not like her, and fear that she is not doing as well as other children. At least 5 percent of American girls suffer from this height-impairing stress disorder. Experts suggest that parents should seek expert help when they notice a child’s tendency to be nervous and anxious. Parents should be concerned about the things that girls over the age of 7 worry about: parental relationships, family finances, their own appearance, mannerisms, height, etc.
