The stress response can be divided into physiological and psychological stress responses, of which the psychological stress response includes both positive and negative psychological responses, mainly non-specific responses of the body to stimulus sources such as bright light, high temperature, surgery and trauma, while non-specific responses refer to different factors in the internal and external environment that can lead to such responses. Moderate stress helps to promote the activation of various body functions and helps the body to cope with the stressor, but sustained or stronger stress may cause some harm. I. Physiological stress: Physiological stress involves the immune, endocrine and nervous systems. If the stress is severe and prolonged, it may lead to physiological disorders and even pathological changes. When the stressor acts on the body, it can lead to extensive effects on the functions of various organs and systems of the body, such as increased insulin secretion, increased heart rate, increased blood pressure, and accelerated respiration. Psychological stress: 1. Cognitive reactions: the symptoms mainly occur in neurotic patients or under acute stress, such as decreased self-awareness, confused thinking, sensory allergy, language retardation, etc.; 2. Emotional reactions: including anxiety, depression, anger and fear, among which anxiety is the most common, moderate anxiety can improve the body’s alertness, but excessive anxiety can cause damage to the individual’s cognitive ability; 3. 3. Behavioral reactions: In the face of stressors, individuals may behave differently, including actively studying the problem, adopting defensive behaviors such as moving away from the stressor, or showing submissive, pleasing, and dependent reactions, mainly to maintain their own safety and preserve their strength. In a stressful situation, the organism usually reacts as a whole, with both psychological and physiological stresses, which cannot be separated.
