What is cold? This is probably the most important knowledge point of summer health care.

Some people say that the temperature is so high in summer, shouldn't we prevent heatstroke and cool down? It's naive to think so.

Because the cold in summer is everywhere, and there are great hidden dangers, just like there is a simple truth, drowning people are often drowning.

It's cold in winter, and everyone knows to wear clothes to keep warm. In summer, in order to make ourselves cool and comfortable, everyone takes the initiative to contact the cold and eat it, so the body is getting colder and colder.

Moreover, heat itself is not as harmful as cold. A large number of stubborn chronic diseases, gynecological diseases, tumors and cancers. Almost all of them are caused by colds.

So if you don't understand the cold in summer, don't prevent it, and don't drive it away, then don't talk about health preservation. If women are unprepared for the cold, they will get hurt in summer.

Second, what is cold?

Cold in traditional Chinese medicine mainly refers to cold evil.

Cold pathogen is one of the six evils in traditional Chinese medicine. All exogenous pathogens with the characteristics of cold, coagulation and aspiration are called cold pathogens, which are the chief culprit of many diseases.

Cold evil can exist anytime and anywhere regardless of seasons.

The harm of cold pathogen to human body does not change with time. For example, the cold evil in summer is more likely to invade the human body and bury the root of the disease.

There are many sources of cold evil, such as wearing less clothes in winter, getting wet in the rain, blowing air conditioning in summer, eating cold food, showing your waist and legs, etc. Will breed cold pathogens in people's bodies.

Three or four cold evils hurt people the most.

There are no types of cold pathogens, but after entering the human body, there are all kinds of cold, among which four kinds of cold pose the greatest threat to the human body:

① Body cold

The so-called body cold, popularly speaking, means that the body is afraid of cold and the body temperature is low, such as cold hands and feet.

Generally speaking, people with body cold are often accompanied by spleen and kidney yang deficiency, and body cold may also induce other deeper cold, such as palace cold and stomach cold.

Characteristics of body cold: pale and dull; Fear of cold and love of heat; Pale lips and tongue; Weak energy, easy fatigue, etc.

② palace cold

As the name implies, it is "cold palace", that is, a series of problems caused by the internal cold stagnation caused by exogenous cold evil or spleen and kidney yang deficiency, which leads to the damage of uterus (internal reproductive organs: uterus, fallopian tube and ovary).

Palace cold is the symptom of cold evil that all women need to prevent and regulate most in summer.

③ excess cold

Excess cold refers to deficiency of yang and excess of yin cold in the body. It is mainly caused by excessive yin cold in the body and damage to yang qi.

Most of them are cold invading the human body, causing local cold pain, such as hand frostbite in winter, which is solid cold, and there are few systemic symptoms.

④ Deficiency cold

Deficiency cold, namely yang deficiency and external cold, refers to yang deficiency in the body and endogenous cold. Mainly due to the lack of yang in the body, which is lower than the normal level, the ability to keep warm is weakened, and the body cannot be warm or cold.

People with deficiency-cold constitution are often accompanied by systemic symptoms such as decreased visceral function, mental fatigue, listlessness and loss of appetite.

Compared with excess cold, deficiency cold is often more harmful to human body, and more than half of the body cold, palace cold and stomach cold mentioned by ordinary people belong to deficiency cold.

Four, the three evils of cold

(1) easy to hurt Yang Qi.

Cold is yin evil, which is the performance of Yin Qi, and it is also the Yang Qi that is most likely to harm human beings.

Because yang qi and cold evil are natural enemies, when yang qi finds cold evil in the body, it will fight back and disperse it.

However, if the cold pathogen prevails, the yang is not enough to drive away the cold pathogen, but it will be injured by the cold pathogen, leading to yang deficiency.

After yang is damaged, cold pathogens will gradually invade the muscle surface, damage the viscera, and appear various serious symptoms, mental fatigue and so on.

② Causing siltation.

The Huangdi Neijing records: "Those who suffer from pain suffer from excessive cold, so they suffer from cold."

Traditional Chinese medicine believes that cold coagulation and cold pathogen are in the body, which makes qi, blood, body fluids easy to condense and meridians easy to block.

Poor circulation of qi and blood, even blocked coagulation, leads to pain, such as dysmenorrhea or stomachache in women, which is mostly caused by stagnation of qi and blood after cold, so the warm pain is relieved and the pain is aggravated when cold.

In addition, it will make people's head, body and limbs stagnate, joint pain, cold pain, paralysis and so on. Therefore, there is a saying that "cold stagnation governs pain".

③ Contraction of the body

Su Wenju's Theory of Pain says: "Cold leads to stagnation of qi"

Cold "in and out" means contraction and traction. When cold pathogen invades the human body, it can make qi converge, and the meridians, meridians and tendons contract and twitch.

For example, people who are afraid of cold rarely sweat, because cold pathogens hurt the muscle surface, leading to closed pores, sweat is difficult to discharge, and people are prone to cold and fever.

There are also human joints, blood vessels, meridians and so on. Under the attack of cold pathogen, qi and blood will stagnate, contract rapidly, expand and contract inconveniently, and be ruthless.

Fifth, the cold in summer is everywhere!

In a word, colds are the enemy of human life, with countless kinds, hazards and diseases.

The cold in summer is everywhere, such as iced fruits, cold drinks, air conditioners and so on.

In addition, in summer, yang floats on the surface of the body, causing emptiness in the body, which makes it easier for the cold to take advantage of it and plant the seeds of disease.

Women are naturally afraid of cold, and they are closely watched by cold evil. So in the next time, until the dog days, the ladies' class will deeply interpret the cold, as well as the symptoms related to the cold, diseases, yang, wormwood, moxibustion and so on.

As long as you understand what a cold is, how to prevent it and how to get rid of it? And practice it, then it is natural to have a healthy body.
