Mom, mom, mom, why is my body feeling so numb?

Whenever we came out of the bathroom, staggering and moving slowly against the wall, the people around us would smile at each other tacitly. Some "bad friends" would quickly run over, stretch out their "evil" fingers and poke our painful and numb calves, making us feel doubly sore and even fall to the ground and roll back and forth.

What is this "deadly" numbness ? Let's talk about it today.

1. Legs become numb after squatting for too long

In daily life, many people have similar habits, such as playing with mobile phones, reading novels or playing games while squatting in the toilet... Dozens of minutes pass in a flash, and when you want to get up, you suddenly feel pain and numbness in your legs.

People can do nothing about this feeling. As long as they move their legs slightly, they will feel a sore sensation in their lower body, which will disappear only after they stand in an awkward position for a long time. So, why do people's legs become numb after squatting for a long time?

In fact, to put it simply, after squatting for a long time, the blood circulation in the legs is not smooth, which affects the normal transmission of nerve impulses. The nerves and muscles in the surrounding tissues are compressed and cannot transmit the stimulation to the brain in the first time, so the legs and feet will feel numb after the body stands up. In addition, if the human body maintains the same posture for a long time, such as the commonly said "numbness from standing", it is also due to the compression of nerves, which makes the nerves confused and produces numbness.

When numbness occurs in the legs, we can relieve the numbness by changing our original posture or stretching our legs and feet slightly ; or we can temporarily change our walking posture and walk with our feet turned inside out to change the way the muscles are stressed, which can also help relieve the numbness; in addition, properly rubbing the numb legs and feet can also eliminate the feeling of numbness.

2. Hands and mouth may also become numb

In daily life, many people like to sleep on their pillows or sleep on their side for a long time. This kind of continuous pressure will lead to poor blood circulation in the hands and numbness in the hands. As long as you develop the habit of sleeping on your back, the numbness will disappear quickly. But if the numbness in the hands persists during the day when you are awake, you should worry about whether you have neuritis or vitamin B deficiency.

Friends who love Sichuan cuisine can't give up the tingling sensation brought by Sichuan peppercorns, and they will even add a spoonful of sesame oil. Now, studies have shown that this feeling comes from a special nerve RA1 in the human body that can sense vibrations. The tingling sensation we usually feel when eating Sichuan peppercorns is actually a sense of touch. Simply put, there is a substance called hydroxymethyl sanshool in Sichuan peppercorns that stimulates the nerves in the human body, causing the tongue to mistakenly believe that it is vibrating at 50Hz, thus producing a tingling sensation.

3. Your elbows will go numb if you accidentally bump them

Many people may have had this experience: Sometimes when we accidentally hit our elbows against the corner of a table or the edge of a door, our entire upper body will go numb, extending from the forearm to the elbow and palm, and it will take a long time to slowly recover. The older generation said that this is because we "hit the numb muscle".

The "numb tendon" at the elbow is called the ulnar nerve. When we bend our arms, the ulnar nerve will be prominent, with only a thin layer of human skin and fat protecting it. But this kind of numbness is easy to solve. We just need to shake or rub our arms to relieve it.

What we really need to pay attention to is the prolonged numbness of the ulnar nerve.

4. Pay special attention to carpal tunnel syndrome when numbness occurs

Carpal tunnel syndrome is also known as median nerve compression , which is a series of symptoms and signs caused by compression of the median nerve in the carpal tunnel. The main symptoms of patients are numbness and pain in 3 or 4 fingers, but in daily life, many people mistakenly think that there is a problem with the cervical spine because of numbness in their hands.

The pain of carpal tunnel syndrome is most obvious at night or in the early morning. The pain sometimes also reflects on the elbow or thumb abduction, with weakness in the palm and inflexibility of movement as the main manifestations.

As modern people's lifestyles have changed rapidly, more and more people are exposed to and use electronic products, and spend several hours a day typing on the keyboard and moving the mouse in front of the computer. Due to the repeated and high-intensity work on the wrist joints, this disease has quickly become an increasingly common modern civilization disease - "mouse hand" .

Research has found that the higher the position of the mouse, the greater the damage to the wrist . Therefore, the mouse should be placed at a slightly lower position, which is equivalent to the height of the elbow when the upper arm is perpendicular to the ground when sitting. Many computer desks do not have a dedicated position for the mouse. If the mouse is placed on the desktop for a long time, the damage to people is self-evident.

The distance between the mouse and the body will also be increased because the mouse is placed on the table. The force in this area is borne by the shoulders and elbows for a long time, which is also one of the causes of neck-shoulder-wrist syndrome. When the angle between the upper arm and the front body is kept below 45 degrees, the distance between the body and the mouse is more appropriate.

Placing the mouse in a scientific way will greatly reduce the incidence of "mouse hand", allowing every office worker who often sits in front of a computer to do his or her job easily and happily.

Never ignore the symptoms of numbness around you. Numbness can be divided into normal numbness and abnormal numbness. We should pay more attention to long-term numbness in our daily lives!
