Why do you shiver when it s cold, why does your body shiver from time to time, it s not cold that yo

The shivering of cold weather is mainly due to the fact that the surrounding environment is colder than the cold, if you wear it relatively thinly, the human body will generate heat through the action of shivering when it is cold. to protect the human body from exhibiting frostbite and infection.

Shivering is a protective physiological response, an early warning response of the human body. When shivering, it is recommended to change the environment, add clothes in time, and keep warm from the cold.

Long-term shivering will cause cold, and in severe cases, it will show symptoms such as fever, cough, sputum production, and hemoptysis caused by lung infection.

So learn to keep warm when it's cold.

Because the weather is often accompanied by wind and often cold snaps, if you only pay attention to the warm clothes on your body and do not pay attention to wearing a hat when you go out, not only will the heat energy be emitted from the head, but also because the temperature inside the house is higher than the outdoors, it is easy to catch a cold. Therefore, parents should remember to wear a hat for their children when they go out, especially when they go out to class in the morning in winter, when the weather is cold, and pay more attention to keeping their heads warm.

Keep your back warm. Traditional Chinese medicine believes that the back is where the kidney veins live, and colds and colds mostly start from the back. Therefore, keeping the back warm can not only prevent colds, strengthen the kidneys and waist, but also prevent old diseases and aggravation.

Therefore, it is advisable to buy quilts for children in winter, with cotton or silk cotton, which has good thermal insulation and cold insulation performance, and at the same time, children should develop the habit of wearing clothes when they get up at night to prevent colds.

People with this condition are prone to spasm of the peripheral blood vessels, and when they encounter cold air or cold water, the blood vessels of the hands and feet will constrict, and the blood circulation will not be smooth, and the hands and feet will be easy to be cold and purple. In addition, it may also be due to poor sympathetic nerve function, which makes it impossible to tighten muscles in case of cold to produce heat and cold tolerance.

Hello! There are many reasons for this. For example, you don't wear enough to keep warm; Or you are cold due to hunger, lack of calories in your body.

- -There is an eerie feeling、Horror threatens your body.。

Hand tremor should first be distinguished whether it is physiological or pathological, the amplitude of physiological hand tremor is small and fast, and it mostly appears when it is stationary, which is a small, fast, and irregular jitter.

Physiological hand tremors often occur in situations of nervousness, fear, emotional agitation, severe pain, and extreme fatigue, and once the causes of the tremors are removed, the tremors disappear.

Pathological is generally continuous, divided into static and operational, and static is also present when stationary, such as Parkinson's; Motility is not present at rest and occurs during exercise, such as cerebellar lesions; It can also be an endocrine disorder.

People with trembling hands must strengthen psychological training, do not be nervous and excited, and continue to practice repeatedly, only repeated practice can overcome the bad habit of shaking hands.

Xiao Zhao reminded everyone that you can run more, do push-ups, and carry a lot of things up and down the stairs, so that you can definitely heal if you do it repeatedly, and you must pay more attention to controlling your hands and relax your mood.

The American "Life Sciences" magazine **19** said that everyone has this feeling: a cold wind blows, **it will be tightened, and the teeth will rattle, which is shivering, also known as shivering. But why is this happening?

Scientists have recently unraveled this mystery: it's because the brain's connected system monitors the temperature of the brain and determines when to start shaking.

Tremors are numerous unconscious or subconscious functions that the body regulates on its own.

one. Other similar self-stabilizing functions include respiratory rate, blood pressure, heart rhythm, and weight regulation. Shivering is the last line of defense for keeping your body warm.

Kazuro Nakamra, a researcher at the Medical University of Oregon in the United States, said: "Shivering generates heat in skeletal muscle, and it is often the last way the body maintains its internal temperature in a cold environment. ”

Nakamla and his colleagues studied rats and identified a quivering sensory pathway from the mice** to the brain called the paralateral brachial nucleus.

"One of the interesting aspects of this study is that it shows the trembling sensory pathway, which we can think of as the brain's wiring system, which is similar to, but not identical, to the conscious cold-aware sensory pathway," Nakamla said. In other words, your body uses two different but closely related sensory systems to unconsciously perceive the cold at the same time.

This sensory system, which researchers have discovered in the brain, also manipulates other cold control mechanisms, such as restricting blood flow in **.

Because people shivering when they are cold can produce some heat.

Explain that you feel cold or urgent, wear more clothes, turn on the heater, or drink some hot drinks, if you still shiver, please seek medical attention in time.
