How does the feeling of stepping on the air come about?

The calculations that the human brain does to keep your body balanced are very complex, except that it doesn't require your consciousness, so you can't feel it. Man has evolved three systems to understand each of these three aspects of information, which is summarized in the cerebellum, which is the center for processing the sense of balance.

1. Vestibular system: tells you "the movement state of the body". The vestibular system is in the ear, and it's the organ that makes you motion sick. It is responsible for sensing a person's position, rotation, sway, and directional acceleration in 3D coordinates.

2. Proprioception: tells you "what posture the body is in". Proprioception is composed of a series of receptors distributed in the motor system, which sense the position and movement of the body's many muscles, joints, and tendons.

The cerebellum synthesizes this information to know what position your body is in.

3. Visual system: tell you "what the surrounding environment looks like", such as whether there is a brick in front, whether the ground is hard or soft, etc., this information is very important for maintaining balance, because the human body posture can not be adjusted in an instant, and the amount of advance must be calculated to ensure that the body is still in a state of balance after a few seconds.

Interestingly, these three aspects of information represent the past, present, and future of a sense of balance, respectively. The cerebellum is responsible for analyzing all the information in these three aspects, guiding the posture of the body, and ensuring balance. In fact, the information collected is insufficient.

The cerebellum thinks that there is still a step ahead, so it is ready to step on the step, as I said earlier, this preparation is very complicated, such as how high to raise the hind foot, when the thigh and calf muscles contract, when to relax, the position of the Achilles tendon and the ball of the foot, when to adjust the center of gravity in the anterior-backward and left-right directions, when to start lifting the forefoot, and so on. <>

The professional term for the posture of human legs, feet, body, etc. is called posture, and the posture of an object directly affects its movement. Walking as a human or quadruped animal requires constant adjustment of posture to maintain balance, which is a very complex process. To date, humans have not been able to build such a complex system.

As human beings, we need to make a judgment about the environment before adjusting our posture, and decide how we need to adjust our posture according to the environment. If the actual environment is not the same as the environment on which the posture is adjusted, it will lead to a situation where one foot is empty. Similarly, when you lift an object that looks heavy but is actually light, it's the same process as stepping into the air.

Muscle jumps often occur during a person's active sleep, which also belongs to the period of falling asleep for the first time. When you first fall asleep, you will have dreams, and abnormal neuromodulation can cause unexpected stamping.

This is due to the nervous reflexes that occur when people are too nervous and tired during the day, and once they relax during sleep. It does not affect physical health, but it is still recommended that everyone try not to have too much stress.

It is related to their own physical fitness, as well as the usual tiredness and pressure at work. It is recommended to soak your feet more before going to bed to help you sleep.

It is when we are sleeping that we dream, and in the dream we may dream about some higher places that make the body react.

This condition is generally due to psychological tension, and it may also be related to the lack of certain trace elements in the body.

I believe that many people have had such an experience, when sleeping, suddenly have a feeling of stepping on the air, and then wake up from sleep, and some people will even jump up directly. This condition may be related to psychological factors, such as the physical reflex that occurs when a person is in a high-load mental state for a long time. Some people have a lack of trace elements in their bodies, such as calcium, which we often mention, and this will also happen when the time comes.

1. The first reason is psychological factors. 2. The second reason is physical factors. 3. The third reason is a special factor.

This symptom is caused by hypnocymosis, which is normal, and can be reduced by drinking a glass of milk before bedtime or soaking your feet in hot water.

This is mainly due to muscle spasms, which produce a momentary twitch, a normal physiological phenomenon.

It is because many people sleep very deeply when they sleep, and their brains think that people are "dead", so they will suddenly have a feeling of stepping on the air to judge people's vital signs.

It should be in the long body. This is a very normal developmental phenomenon, and it is normal for everyone to have such problems.

This is a normal muscle twitch that occurs when the patient is overworked.

This is because you may have nightmares while sleeping, or you may have a light level of sleep, which is why you feel this way.

The main manifestations of vertebral artery insufficiency are: (1) acute onset, more common in middle-aged and elderly people, mostly accompanied by cervical spondylosis, which can be reversed; (2) dizziness or dizziness may be accompanied by nausea, vomiting or tinnitus; (3) ataxia, mostly one limb, manifested as unsteady standing, a sense of emptiness, and tilting to the affected side when walking; (4) Half body numbness, weakness, slurred speech, blurred vision, diplopia, headache, etc. (5) Transient amnesia, etc.

It is recommended to perform cervical spine radiographs and do brain CT, blood glucose, blood lipid and other examinations.

The blood pressure of the elderly is not high, and after the symptoms of insufficient blood supply to the vertebral artery, they should be active, and aspirin 75mg a day can be given orally. Dizziness can be taken with vertigo arrest and anti-vertigo. If necessary, Xuesaitong + 5% glucose or 250ml of normal saline should be used intravenously for 1 day to prevent and treat cerebral infarction.

According to the above inference, you can take your father to have a lower cervical spine X-ray, brain CT, blood sugar, blood lipid and other tests, because these diseases will cause the phenomenon of stepping on the void.

Maybe I've been eating irregularly lately...

Dreaming and growing are related.

Nervous. Busy not translating l road feet in the air.
