What's with the nerve tremor?Nervous tremors were known as tremors in medicine. It referred to irregular rhythmic tremors in part or all of the body. The causes could be divided into two categories: physiological and pathological.
** 1. Biological reasons **
1. ** Triggered by specific circumstances **
- Under nervousness and anxiety, the human body's neurotransmitter, adrenaline, and other sympathetic nervous system participated in the activity, causing a large number of galloping substances to activate, causing the small veins to contract rapidly, increasing the nerve's excitement, and causing the nerves to tremble.
- It could also appear when one was tired, such as overwork, high work pressure, long hours of overtime, poor sleep quality, etc., which could lead to mental stress, which could lead to physiological muscle twitches such as sleeping-related muscle twitches (similar to nerve tremors).
- After ingesting substances such as coffee or Nicotine, it will cause nervousness and other conditions, and there may be nerve tremors.
- When people were in a cold environment, the skin sensed the "cold" signal and sent it to the hypohedron. In order to maintain body temperature, it would generate heat through muscle twitching (i.e., trembling). Shivering occurs when body fluids are lost (dehydrated), similar to shivering in a cold environment. In a hot environment, if you suffer from iron deficiency leukemia (insufficient iron in the body, the speed of oxygen transport in red blood cells is reduced), you may also tremble.
- When the blood sugar level in the human body is lower than the normal value, the secretion of adrenaline will increase, resulting in the hypobaric syndrome. The body will tremble. This is a kind of compensation reaction, which is more common in patients with diabetes who inject hormone.
2. ** Normal physiological phenomenon **
- About 70% of people experience sudden tremors in their sleep (hypnosis). This is a normal physiological manifestation, not caused by a disease. For example, when the breathing rate is too low during sleep, the brain mistakenly judges that they are falling from a high ground after falling asleep. Instinctively, they tense their muscles to obtain balance, send pulses to wake up the body, and suddenly feel like they are stepping on air (similar to electric shock). This kind of tremors is a normal physiological situation. In addition, hiccups, fatigue, or nervousness were also the same type of physiological muscle twitches. For infants between 3 to 6 months old, it was normal for them to feel nervous or suddenly tremble when they touched their limbs in their sleep or during normal times. This was because the cerebral cerebral suppressive center was not fully developed, and the flexor muscles were more dominant than the flexor muscles.
** 2. Pathological causes **
1. ** Nervous system disease **
- Parkinsons 'disease was a chronic neurodegeneration disease that affected the central nervous system. Its clinical manifestations included resting tremor.
- Essential tremor would cause the nerves to tremble.
- Cerebellar diseases (e.g., cerebellar obstruction, cerebellar hemorrhage, etc.) would cause intentional tremor. That is, when performing purposeful and directional movements (such as pointing at the tip of the nose with a finger after straightening the arm), the hand would shake uncontrollably and stop shaking when the finger reached the tip of the nose.
- Brain diseases may cause symptoms of muscle twitching, such as headaches, dizziness, etc., which may be manifestations of brain diseases such as tumors, brain degeneration, stroke sequelae, and brain trauma sequelae. At this time, the brain may send out a distress signal.
2. ** Other diseases or conditions **
- Restless legs syndrome was a sleep-related movement disorder. The main symptoms were extreme discomfort in the lower limbs during sleep at night, accompanied by obvious tingling and burning sensations, which would cause the lower limbs to shake.
- Some diseases, such as sequelae of oxygen deficiency, epilepsy, etc., may frequently cause body tremors during sleep, and may also be accompanied by dizziness and headache.
- Hysteria was a mental disorder caused by mental factors, and it would cause the body to tremble.
- Hyperthyreosis can cause pathological tremors.
- Alcohol withdrawal, infection, and other diseases could also cause nervous tremors.
- The side effects of some drugs could cause physiological tremors, such as alcohol, opioids, King's drugs, vasodilators, epinephrins, and antidepressors. Heavy metal poisoning such as mercury and lead could also cause physiological tremors. In addition, when a urine tract infection spreads to the kidneys, it will cause the body to tremble unconsciously, and when an acute upper respiratory tract infection causes a high fever to persist, muscle abnormalities will occur, and the body will tremble.
If nerve tremors occur frequently or are accompanied by other symptoms such as increased muscle tone, bradykinesia, etc., it is recommended to seek medical advice in time to determine the cause and follow the doctor's advice for examination and treatment.

The cultural opera area had scenic spots such as Shuangqing Villa and Jiangnan Water Village, while the martial opera area had scenic spots such as Xianyang City, Prop City, and Vehicle Cannon Garage. The works filmed at the Bayi Film and Television Base included the TV series "Sword,""Snow Leopard," and the movie "The Founding of a Nation." The Bayi Film and Television Base was the only multi-functional military film and television production base in the country. It provided outdoor shooting sites and props for film production, and was open to tourists.
Is there Hu Bayi in reality?In reality, there was a person named Hu Bayi, but in different context, he referred to different individuals. Hu Bayi, who was in the field of management consulting, was the chairman of the Parmington Management consulting Group. He was a famous management consulting expert. In the novel "Ghost Blows Out the Light" and related derivative works (such as the movie "Ghost Blows Out the Light: Dragon Searching Tactics"), Hu Bayi was the male lead.
