Why do hands shake after exertion?

First of all, rest assured that this is a normal physiological phenomenon and has a professional name: physiological tremor. Physiological, as the name suggests, is the rapid shaking of the limbs that normal people show when they are nervous, tired, and afraid. This disappears when you are quiet and resting.

We can think back or imagine that when you first took the stage to give a speech, 10,000 spectators, the spotlights, the silence, and the judges stared at you with pin-like eyes......Or you have never been in love, and the goddess you love in your heart suddenly takes the initiative to ask you to watch a movie or drink coffee, if your hands are shaking at this time, this is a normal phenomenon.

So why is this happening? Generally speaking, if our human body wants to move, it needs nerves to direct muscle contraction. This process is extremely complex, first of all, it needs to send the highest conscious instructions in the anterior cerebral gyrus, then the ** anterior gyrus of the frontal lobe of the brain sends a direct signal to the anterior horn of the spinal cord, and then the spinal cord sends out neurons to the muscles, and finally the muscles contract.

This process solves the problem of whether the human body can move at will.

In addition, with the participation of nervous tissues such as cerebellum, basal ganglia, midbrain, pontine (frontal pontine bundle), ear, spinal cord, etc., it is necessary to adjust the strength of the muscles, when and how much contraction force this muscle has; When and to what extent. This solves the problem of precision and coordination of movements.

When the command is delivered to the muscle, calcium ions flow into the nerve axons, and then acetylcholine is released from the nerve endings to bind to the sarcomembrane acetylcholine receptors at the neuromuscular junction. After the receptor binds to the transmitter, the ion channel will open, the sodium ion will inflow, and then the calcium ions of the muscle cells will be released, which will bind to troponin, and the thick muscle filaments will slide, and then the muscle will contract. This process consumes a lot of adenosine triphosphate (ATP).

After this complex series of processes (about seconds or so in the real world), the muscles contract forcefully.

And if you have normal human activity, you might have to contract 100 times per minute, but today you have 1,000 contractions per minute. At this time, the transmitters and ions of the nerve endings are unstable and more easily depolarized, so the contraction of the muscles is no longer stable. As a result, physiological tremor occurs.

Of course, this is a physiological tremor in normal situations, which is very different from pathological resting tremor, essential tremor, intention tremor, and asterixis. To put it simply, the former can be had by normal people, and the latter only appears when the disease occurs.

In traditional Chinese medicine, the qi deficiency syndrome is used to explain that the activation of human physical strength needs the support of qi, as the saying goes, when after vigorous exercise, especially after a short period of overload and vigorous force, the body's qi and blood support is insufficient, the body will tremble, and there will be shivering, the body's qi is divided into vitality, zongqi, health qi, camp qi, insufficient vitality is the lack of congenital endowment, vitality comes from the congenital parents' father's sperm and mother's blood and acquired spleen and stomach luck, the vitality of the vitality will be low, and the vitality will be low, and they are more afraid of cold than normal people. It can be improved by supplementing the vitality of foods such as red dates, shiitake mushrooms, yams, glutinous rice, etc., and can also replenish qi and yang through exercise, which is called movement and yang in traditional Chinese medicine!

As soon as you exert force, your hands tremble, which proves that the force used is beyond your normal ability, which is normal.

What causes hard hand shaking? Ah, this might be your business tonight, but you'd better go to the hospital and check it out and see what the hell is going on.

Hand tremors are divided into physiological and pathological hand tremors.

Physiological hand shaking is small in amplitude and fast in speed, mostly at rest, and is a small, fast, irregular jitter. Physiological hand tremors often occur in situations of nervousness, fear, emotional agitation, severe pain, and extreme fatigue, and once the above causes of hand tremors are removed, the hand tremors disappear.

pathological hand tremor, medically known as "tremor"; Refers to involuntary tremors of the hand, often permanent. There are two main types: resting hand tremor and motor hand tremor. Among them, resting hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state.

This kind of hand tremor can disappear when sleeping, and the speed of hand tremor is 4-6 seconds, which is relatively regular, and is typical of diseases such as Parkinson's syndrome. Motor hand tremor is a hand tremor that occurs only during exercise and is worse when the movement approaches the target. For example, when the doctor gives a patient a finger and nose test, he asks the patient to straighten his forearm; Then point your index finger at the tip of your nose; The closer the tip of the index finger is to the tip of the nose, the more pronounced the shaking of the hand becomes.

Motor hand tremors are irregular, the amplitude of shaking is large, and it is enhanced by emotion, and is common in lesions of cranial nerves and upper extremity nerves.

There are several causes of hand tremors:

Clause. 1. Parkinson's disease, Parkinson's disease is a neurodegenerative disease common in middle-aged and elderly people, and its clinical characteristics are resting tremor, muscle rigidity, bradykinesia, and postural balance disorders, among which forbidden tremor is manifested as shaking of the fingers in the resting position.

Clause. 2. Essential tremor, essential tremor is a movement disorder with tremor as the only manifestation, 1 3 patients have a positive family history and are inherited in an autosomal dominant manner. The patient's clinical symptoms are postural and action tremors, with shaking of the fingers when exertion.

Clause. 3. Hyperthyroidism, hyperthyroidism can also cause hand tremors, and the symptoms are obvious when emotional.

Because the muscles are a little strained.

Hand tremors, agitation, fatigue, and hunger are common manifestations of essential tremor.

Sometimes I get sick when I get tired, when I'm hungry, when I write, etc. (Ten miles to stop trembling).

Compared with the hand tremor, if the patient is often or essential tremor, then it is necessary to take timely treatment, compared with essential tremor, the usual use of traditional Chinese medicine is relatively good, the use of traditional Chinese medicine to take the first way to take treatment can be one person, specifically for each person's physique to take targeted treatment, more conducive to the treatment of essential tremor, and the actual effect will be better.

If you didn't shake before, and you started to shake recently, it should be caused by your recent labor or mental pressure and poor rest at night, so it is recommended to buy some blood and soothing drugs to improve sleep quality, if not, please seek medical attention in time.

I can do it with both hands. However, self-evaluation, if you exercise more recently and practice more words, it seems that you will shake lighter, but you will still tremble.

If you are tired, rest more, your body is the capital of the revolution.
