What is the reason for frequent sha?

In fact, in medicine, sha disease is called sha disease, which is also called miasma. The specific manifestation is that the body will feel very weak and the body temperature is very high. It is an acute disease. For friends who often work outdoors, this disease will not feel unfamiliar. So, some friends often have sha, what is the reason for this?

There are two reasons why people get sha, internal and external.

The internal cause is that this person has insufficient lung qi. The lungs are responsible for the body's defenses against disease and deficiency of lung qi makes it impossible to resist invasion by foreign enemies. The external causes are polluted air, humid heat, and a lot of fire gases in the environment. For example, the air in cars and air-conditioned rooms is very bad, and people with weak lungs will definitely suffer. When these internal factors collide with external factors, people get sha. The pathology is that dampness, heat, and filth accumulate on the skin surface, blocking the meridians, which causes problems.

There are many air-conditioning diseases nowadays. In fact, this is sha, but the hospital gave it a high-level name. In fact, it is still the same old thing called sha.

Sha often occurs between summer and autumn. It is a common epidemic disease. Its pathogenesis is described in Zhang Lu's "Zhang's Medical Encyclopedia" in the Qing Dynasty: "It is all caused by the deficiency of Qi in the middle. The spleen and stomach like fragrant and dry things, and hate smelly and damp things. Now the spleen and stomach are deficient in Qi, or there is too much dampness, so they cannot control it. Therefore, the smelly and disgusting air can invade without restraint." Because the Qi in the middle is originally deficient, it is exposed to foul toxins, which leads to shazhang, and the condition turns from deficiency to excess.

In modern society, foul air is prevalent throughout the body. Gasoline, diesel, car exhaust, perfume sprayed on flowers, air freshener sprayed in the room, and so on, are all foul air. Gasoline and diesel are water in nature but fire in use, and they are damp and hot together, which can cause serious harm. Air fresheners and flower perfumes are similar. Air-conditioned rooms are rich in static ions, and the air is closed, which is damp and turbid, and both dampness and heat are trapped in them. Modern living rooms are not well ventilated and are full of filth, which can cause harm. Nowadays, there are many alcoholics who drink wine every day. The nature of the wine rises, and the qi and blood are blocked on the skin surface, causing blood stasis on the skin surface, which can also cause shazhang. Therefore, in modern society, the sources of foul toxins are becoming more widespread, and the harm caused by shazhang is becoming more and more serious.

The symptom of sha has been discussed by various medical experts since the Ming and Qing Dynasties, and the identification and treatment of sha is also very common among the people.
