To prevent psychosomatic diseases, we should not only start early, but also give attention to both psychological and physical aspects. For people with obvious psychological weaknesses, such as irritability, depression, loneliness and anxiety tendency, we should improve their personality through psychological guidance as soon as possible, and use psychological behavior techniques to correct obvious behavioral problems, such as smoking, alcoholism, overeating and too little exercise. For some people with genetic predisposition to psychosomatic diseases, more attention should be paid to strengthening psychological defense. Because psychosomatic diseases have a great influence on individuals, we should prevent them from both psychological and physical aspects.
