What are the manifestations of psychological stress?

The manifestations of excessive psychological pressure: ① I feel strong negative psychological stimulation recently, or suffer from persistent negative psychological stimulation for a long time, and my spirit is always in a state of tension. After a long period of fatigue, I still feel very tired after a night's rest, or I can't find the reason; ③ Patients often have tension headache, insomnia, unstable blood pressure, arrhythmia, loss of appetite, constipation, diarrhea and other symptoms. (4) Emotional instability, often flustered, bored, irritable, or lazy, melancholy, dreamy, lacking motivation to communicate with people; ⑤ Work and study efficiency is obviously reduced, thinking activity is slow, attention is not concentrated, and memory is poor. If you have the above symptoms and can't find other reasons, it is also a psychological burden.

Medical research has confirmed that people's autonomic nervous function and endocrine system will undergo drastic changes under psychological overload, such as excessive excitement or tension, rapid heartbeat, high blood pressure, slow gastrointestinal peristalsis, reduced or stopped secretion of stomach, pancreas and bile, and increased secretion of sweat glands. Pupils dilate, adrenal gland secretion surges, blood sugar concentration rises, and breathing deepens and accelerates. If the stimulation beyond psychological endurance lasts for a short time, once the stimulation disappears, the nervous system will gradually become normal. If the bad stimulation lasts too long, some organs of the human body will decline in function, and then fail, causing psychosomatic diseases or worsening the original diseases sharply, and even inducing sudden death.
