Disgust is part of the body's immune system, which belongs to the "behavioral immune system", which drives people to stay away from toxic substances and disease-causing pathogens through psychological mechanisms, so as to avoid the body from being attacked. For example, studies have shown that pregnant women are more likely to develop feelings of disgust, partly because their physiological immune system functions will decline in order to prevent the immune system from attacking the fetus, so it is necessary to turn up the behavioral immune system to maintain adequate immune protection. The normal aversion response can help people quickly move away from "toxic" people, things, relationships, and environments, so that people can be protected from the negative effects of the outside world and maintain physical and mental health to the greatest extent.
But in modern society, the mechanism of disgust also generates a lot of *** disgust is the main ** of almost all discrimination and prejudice. Because people naturally shy away from what they consider "toxic", it is easy to trigger disgust and reactions when confronted with people who are sick, physically disabled, or even just different from us. Not only that, but when we are morally or religiously critical of certain behaviors, we also see them and the people who have them as pathogens, resulting in a reaction of rejection, avoidance, and resentment, forgetting that they are also people like us. One of their actions, or the actions of one person in their group, is not representative of the whole of a person or a group.
Since disgust is part of the immune system, it can also lead to allergies and hyperactivity, which can cause problems. Studies have shown that phobia, anxiety, and obsessive-compulsive disorder are all associated with disgust. If people have to suppress their disgust, spend long periods of time with people they feel are "toxic", or have difficulty leaving in an environment of "toxic" tissues, they can develop a range of gastrointestinal and immune system problems, such as persistent acid reflux, stomach upset, and inexplicable allergies. Because the body is always inseparable from the source of poison, the function of resistance and expulsion will not completely disappear, which will bring a great burden to the body.
Disgust with the outside world is not the worst, after all, we have the option to stay away from "toxic" things. But if the object of disgust is oneself, the situation is very serious. Many people with eating disorders have a severe aversion to themselves and their bodies, which is often the embodiment of the gender bias and physical discrimination they have suffered in their upbringing, and eventually manifest themselves in the form of anorexia, bulimia, or physiognomy disorders, which are subjectively perceived as "defects" in certain parts of the body. People who have experienced humiliating or stigmatized trauma (such as cyberbullying and cyberbullying) are also prone to deep self-loathing. A large amount of targeted malice and aggression from others can lead to self-doubt and even self-loathing, which in turn can lead to further psychological problems, such as depression, self-harm, and even suicide.
