When the cold air hits, why do some people have cold hands and feet, while others are warm?

Because there are sensors in the human body that can sense low temperatures, which is equivalent to a thermometer in the human body. Between 20 and 25, these sensors make the brain feel "comfortable". Generally speaking, people's comfort temperature is in this range, but everyone feels a different comfort temperature.

This is because everyone's basic metabolic rate and blood circulation patency are different. If the basal metabolism is stronger, then the heat production is higher, so it will be colder and more resistant to freezing, and the comfortable temperature will be reduced accordingly. Smooth blood circulation accelerates the transfer of heat to the limbs, which is also beneficial to the body's ability to resist cold.

On the other hand, if the basal metabolism is slow or the blood circulation is not smooth, then people will be more afraid of cold. Let us know more about the relationship between low temperature and the human body.

First, we set the ambient temperature at 25 degrees Celsius。Under normal circumstances, a person's body temperature is around 37 degrees Celsius. Since the temperature of the surroundings is lower than body temperature, people dissipate heat from the environment.

To keep body temperature constant, the body produces heat to resist heat dissipation.

When exercising, we feel hot because exercising skeletal muscles consumes sugar and converts it into heat。At rest, calories are mainly produced by the liver burning sugar. As blood flows through the liver, it is heated by the liver, which then transfers the heat through the blood circulation throughout the body.

As long as the equation of "heat loss = heat generated" is maintained, a person's body temperature can remain stable.

Because everyone's physique is different, some people are born with cold hands and feet.

Because everyone's physique is different, we can still understand it.

It may be that some people's physique is still more Korean, and it should be a problem of qi and blood.

Because this thing has a direct relationship with everyone's physique. Different constitutions are different.

1. Liver qi stagnation.

If the body's liver qi is often suppressed, it is easy to cause unstable hunger, upset, and anger. At the same time, the qi and blood could not reach the limbs, and the hands and feet were cold.

2. The meridians are not smooth.

Poor meridians also vary depending on age, and the elderly may have a decline in the function of the heart and kidneys, resulting in insufficient motivation; For young people, it is likely that they are stressed or have poor peripheral circulation, which leads to cold hands and feet.

3. Spleen and stomach deficiency and cold.

Deficiency in the spleen and stomach can affect the delivery of yang energy, preventing it from reaching the ends of the limbs, and the grinding of the trousers can lead to cold hands and feet, as well as loss of appetite, yellowing of the face, and fatigue.

Improvement methods:

Here's an answer to this question for you. First of all, I would like to recommend some must-have good things for your daily life in autumn and winter.

The first is a winter artifact, that is, the warm quilt machine! It is recommended for days when there is no heating in the north, after all, it takes courage to enter the cold quilt at night! In addition, of course, it is most recommended for those in the south who have to face the wet and cold, and the Qingqi warm quilt machine is the artifact that ends the cold quilt!

It blows hot air at about 70°C into the bed through a pipe, which can not only heat but also dehumidify, and by the way, sterilize and remove mites.

Presumably, the last thing you want to do in the autumn and winter is to brush your shoes, or to warm up at home in the morning, as soon as you go out, step into your shoes, your feet are cold, and your good mood for the day is ruined! At this time, the shoe warmer is simply an emergency artifact!

The shoe dryer can generally be retracted to meet the use of different members of the family, and at the same time of deodorization and sterilization, it can ensure that it is warm and dry when going out. But remember not to wet your shoes and dry them directly, it is easy to cause a short circuit!

Finally, I believe that all friends should have felt the warmth brought by the warm baby! This is a good thing to use urgently when going out, when traveling or traveling in a colder city, even if you wear more, the body will tremble because you are not used to this cold, and the warm baby patch can be put in handy, and you can stick a few more on your body to help people quickly adapt to low temperatures.

I hope I can help friends in need.

In the cold winter, many people feel cold in their hands and feet. Some people simply attribute cold hands and feet to the weather, but it's not that simple. In addition to the climatic factor, cold hands and feet have a lot to do with the factors mentioned below.

Lack of yang energy. In the view of traditional Chinese medicine, cold hands and feet are actually a kind of "closedness" of the body, and the so-called "closed" is impassable. Affected by factors such as cold weather and body cold, the liver veins are cold, and the hematopoietic function of the liver is affected, resulting in a lack of yang qi in the kidneys, cold limbs, red or white hands and feet, and even painful sensations.

Circulatory obstruction. In low temperatures, the body's ability to constrict blood vessels and blood return will be weakened, making the blood circulation of the hands and feet, especially the fingertips, poor, which is often referred to as "poor peripheral circulation".

In addition, people with anemia are prone to insufficient circulating blood volume, and the heart is weak and unable to make blood reach the parts of the body, which will lead to cold hands and feet.

Hormonal changes. The hormone level of the human body is affected by the environment, especially menstruation and childbirth, which can cause changes in female hormones, affecting the nervous system, causing subcutaneous vasoconstriction and reduced blood flow, which can lead to cold syndrome. Women make up the vast majority of people with cold hands and feet. Therefore, women need to pay more attention to the maintenance of their bodies in winter.

Illness and psychological factors.

Certain diseases, such as Raynaud's disease and Raynaud's phenomenon, multiple Takayasu's arteritis, and thromboangiitis obliterans, can cause cold hands and feet. In addition, people who are overstressed, overworked, psychologically sensitive, and often restless are also at high risk of cold hands and feet.

The common causes of cold hands and feet in winter are seasonal cold, spleen and stomach deficiency and cold (spleen and stomach weakness and cold), lack of qi and blood, kidney yang deficiency, etc., which can be appropriately conditioned by changing food and clothing, dissipating cold in temperature (dispelling cold evil with medicine that warms the spleen and stomach), replenishing qi and blood, and warming and replenishing kidney yang.

The holistic view of Chinese medicine believes that man and nature are a whole, and the natural temperature changes with the seasons.

When the body's spleen and stomach are deficient and cold, there will be cold hands and feet, and the symptoms will be aggravated when eating raw and cold food, often accompanied by stomach pain. It is mostly caused by irregular life, coupled with a cold diet and external cold, so under the guidance of a doctor, you can choose aconite Li Zhong pill isothermal Chinese patent medicine for conditioning.

When the body's qi and blood are insufficient, there will also be symptoms such as cold hands and feet, palpitation and shortness of breath, insomnia, dreaminess, dizziness and fatigue.

When the body's kidney yang deficiency is also manifested as cold hands and feet, accompanied by chills, frequent urination and self-sweating (involuntary sweating during the day, aggravated by a slight sweating), waist and knee soreness (a feeling of soreness and weakness in the waist and knees) and other symptoms.

The choice of drugs should be used under the guidance of a doctor, and self-medication should not be allowed.

This is caused by a lack of yang energy, which can lead to poor blood circulation in the body, coupled with cold air, which is why the limbs are cold.

Cold hands and feet are due to the imbalance of qi and blood, qi and blood can not be regulated, and the blood cannot run to the end blood vessels, so there will be cold hands and feet, which is generally more common in qi stagnation, that is, people who are not in a good mood and are easy to be anxious will also have cold hands and feet caused by qi stagnation.

There are a lot of sayings, some are too strong in the liver fire, some are not enough yang, and it may be that they are wearing too little and the warmth work is not in place, so it will be cold.

It is very common for some people to feel cold in winter with cold hands and feet. This is mainly due to the fact that the temperature in nature decreases, the yang energy is insufficient, and the body's own yang energy will also be insufficient, and the body will show signs of yang deficiency. In addition, because of the cold weather, the body's blood vessels will constrict and the ability of blood return will be weakened, so that the blood circulation of the hands and feet, especially the fingertips, is not smooth, which is often referred to as "poor circulation of nerve endings", resulting in the hands and feet always feel cold.

This situation generally occurs in women, especially middle-aged and older women, and mental workers are more likely to have cold hands and feet than manual workers, and it is less common in young men who are in good health.

Cold can cause poor blood circulation throughout the body or in the body, or blood circulation in the extremities of the limbs, which can lead to cold hands and feet. Frequent long-term cold hands and feet can be called "cold syndrome". Traditional Chinese medicine theories believe that this is a reaction to qi deficiency, qi stagnation, and yang qi deficiency.

During special physiological periods such as menstruation, pregnancy and childbirth, women are more likely to cause cold hands and feet due to physical weakness. If it is not prevented in time, it will lead to poor spirit, physical chills, and in severe cases, it can also cause varicose veins in the lower limbs.

1 Eat American ginseng. This is a good medicine for replenishing qi, which is peaceful and tonic but not dry. It can be drunk by soaking in water alone.

2 Eat sesame seeds and peanuts. Rich in vitamin E and a variety of nutrients, it can help the absorption of vitamin B and strengthen the ability of nerves to fight cold. Vitamin E

It also has the effect of dilating blood vessels, which can enhance blood circulation in the extremities of the limbs.

3 Eat onions, peppers, and other foods that can help the body produce calories and promote blood circulation.

Other measures: Soak your feet in hot water at ordinary times, which can not only warm your body, but also relieve tired nerves.

Ways to improve cold hands and feet in winter.

Mainly because of the venous blood vessels. The veins and blood vessels are under **, far away, and the heat is emitted when the blood circulates and the hands and feet are hot, and the hands and feet are cold.

You can take a look at the blood vessels in the hands of people with hot hands and feet.

The main cause of cold hands and feet].

The heart is weakened and unable to get blood to the ends of the body.

The amount of blood in the body is insufficient, and the heme and red blood cells are low.

Blockages in blood vessels, fever, colds, etc., can affect the central nervous system of the brain, resulting in cold hands and feet.

Sympathetic nerve function is faulty, making the muscles unable to contract when cold and producing heat to withstand cold.

Who are most likely to have cold hands and feet].

Girls who are too skinny.

Girls with thinner bodies and weak cold constitutions are most likely to have cold hands and feet, because of the peripheral blood circulation of this type of person.

Poor, it is easy to disturb the mechanism of body temperature regulation, and cold hands and feet are due to the poor regulation of autonomic nervous system function and vascular changes.

fine caused. In addition, the toes, knees, shoulders and fingers belong to the joint areas with more exercise, because the fat and blood vessels are opposite.

Less, the heat is easy to lose.

When blood sugar is too low or blood pressure is low.
