Physiological reactions caused by psychological reactions

The physiological reaction caused by psychological reaction is the direct impact of emotional stress on the body through the nervous system and endocrine system, which mainly manifests as heart palpitations, gastrointestinal discomfort, headache, muscle tension, decreased immunity, etc. These reactions are usually triggered by short-term stress or chronic stress and involve mechanisms such as sympathetic nerve excitation, abnormal cortisol secretion, and autonomic nervous system disorders.

1. Cardiovascular reaction:

Sympathetic nerve excitement during emotional excitement can cause increased heart rate and blood pressure. Long-term psychological stress may lead to coronary artery spasm or even arrhythmia. It is common clinically for patients with anxiety disorders to experience pressure in the precordial area, but there is no organic disease on electrocardiogram examination. This "cardiac neurosis" is a typical psychosomatic reaction.

2. Digestive system reaction:

Psychological stress can change the rhythm of gastrointestinal peristalsis, and elevated cortisol inhibits the secretion of digestive juices. Acute stress may cause vomiting or diarrhea, while chronic stress can easily lead to functional dyspepsia and irritable bowel syndrome, manifested by symptoms such as postprandial bloating and changes in bowel habits.

3. Respiratory system reaction:

Anxiety often induces hyperventilation syndrome, with symptoms such as shortness of breath and suffocation. Psychological factors in asthma patients can aggravate airway hyperresponsiveness. Research shows that depression can increase the frequency of asthma attacks by more than 40%.

4. Immune system response:

Chronic stress affects immune function through the hypothalamic-pituitary-adrenal axis, with persistently elevated cortisol inhibiting lymphocyte activity. Such patients are more likely to have recurring colds, have slower wound healing, and may have aggravated symptoms of autoimmune diseases.

5. Skin reaction:

Psychological factors can induce skin abnormalities through the release of neuropeptides, with common manifestations such as neurodermatitis, alopecia areata, hyperhidrosis, etc. About 60% of patients with chronic skin diseases such as psoriasis and eczema report that mood swings can significantly aggravate skin lesions.

To improve psychological physiological reactions, it is necessary to establish a regular schedule and ensure 7-8 hours of sleep a day to help stabilize autonomic nervous function. It is recommended to do aerobic exercise such as brisk walking and swimming at least three times a week. The endorphins secreted during exercise can relieve anxiety. Add tryptophan-rich bananas, oats and other foods to your diet to promote serotonin synthesis and reduce caffeine and alcohol intake. Relaxation training such as mindfulness meditation and abdominal breathing for 15-20 minutes a day can effectively reduce cortisol levels. If symptoms persist for more than 2 weeks or affect daily life, it is recommended to go to the psychosomatic medicine department or psychology department for professional evaluation.
