Before talking about scraping, people often ask about the effect of scraping due to heat stroke. Let me briefly answer:

In the hot summer, sometimes when we stay outside for a long time, we feel hot and dizzy, and even feel very tired after being exposed to the sun, and even sore shoulders and necks come to the door, so I immediately think that scraping can relieve heat stroke, but some people scrape. After the whole body is refreshed, but some people get more and more pain after scraping, so is scraping really effective?

According to the theory of traditional Chinese medicine, when the pathogenic heat invades the human body, it is called heat stroke. The symptoms of heat stroke are dizziness, weakness of limbs, nausea and vomiting, chest tightness, and severe coma. When it is dry, correct scraping can promote blood circulation on the surface of the body, help metabolism, and expel the evil spirits in the body together, which has the effect of sweating.

However, after scraping, you need to add warm water, do not drink cold water immediately!

In addition, the principles of scraping, scraping parts and techniques have specific skills, and some people and some times are not suitable for scraping, so let’s learn more about scraping together!

What is Gua Sha? What is the “Sha” that is scraped out?

People often use traditional therapy to relieve muscles and bones and relieve fatigue. Among them, massage, cupping and scraping were originally medical methods of Chinese medicine theory, and now some people use them for non-medical behaviors, such as beauty and health preservation.

The principle of scraping in traditional Chinese medicine is the theory of meridians and collaterals. It is a method of using special tools and lubricants to dredge the meridians and collaterals, adjust the viscera, and smooth the circulation of blood. , to exorcise evil spirits and detoxify, help link physical discomfort, and daily scraping can also be used for health care. Therefore, scraping has become a traditional health care treatment spread among Chinese folks since ancient times, and ordinary people can also operate by themselves, such as shoulder and neck scraping and back scraping.

“Sha” is the stasis in the qi and blood of the meridians, commonly known as Sha poison, which manifests as small red spots on the skin. It is a harmful toxin in qi and blood that hinders the operation of the body. It will affect the absorption and metabolism of nutrients in the human body, accelerate cell aging and even cause diseases. Therefore, there is a saying in traditional Chinese medicine that “all diseases can cause Sha”.

Usually when scraping, we will repeatedly scrape and rub on the epidermis, so that purple-red blood stasis spots, red miliary blood spots or spot bleeding appear locally on the skin, which is “exiting sha”.

The main effects of scraping are as follows:

Preventive health care

Pain relief

sweating table

Warm meridians and dispel cold

Detoxification and exorcism

adjust endocrine

Cardio-strengthening and strengthening

Is scraping helpful? Which parts can be scraped with scraping? Foreign experiments tell you the truth!

Gua Sha and detoxification is the impression of scraping in many people’s minds. It is true to say that, because the effect of scraping is to promote blood circulation, promote metabolism, and have the same effect as sweating, so it will be more effective for functional diseases. Such as migraine, dizziness, indigestion, loss of appetite, nausea, insomnia, constipation, heat stroke, fatigue, etc.

We can scrape a wide range of parts of our body, from head to toe. The benefits of scraping vary according to different parts and stimulate different meridians. For example, the effect of scraping on the shoulder and neck can relieve muscle soreness, eliminate heat stroke, eliminate wind-cold, and reduce fever. To reduce fire, etc., on the contrary, the effect of scraping on organ diseases is limited, such as heart disease, kidney disease, etc., scraping has no obvious effect on these diseases.

Does scraping work? Scientists say so

In a foreign randomized controlled trial, 48 patients with chronic shoulder and neck pain were divided into an experimental group, and the scraping therapy and the control group were used to test the curative effect of scraping. The results confirmed that the patients in the experimental group received scraping therapy for 1 week. After treatment, the severity of neck pain was significantly improved, but whether long-term treatment can have the same effect still needs more extensive experiments to verify.

In addition, other studies have found that scraping can increase human microcirculation by up to 4 times, and the enhancement of blood circulation may play a role in the reduction of local and overall muscle pain, and the response rate of women is significantly higher than that of men. In addition, in animal experiments, It was found that because scraping promotes blood circulation and vasodilation, it can activate the immune cells of experimental mice and strengthen the response to vaccine antigens, so scraping also has the potential to be a physical aid to vaccination.

In addition, it may be surprising that scraping may effectively reduce peripheral neuropathy in diabetic patients!

A randomized controlled trial in 2019, hoping to find out the effect of scraping therapy on diabetic peripheral neuropathy patients, after tracking 60 patients in the scraping group and 59 in the control group, it was found that scraping therapy significantly reduced the symptoms of neuropathy in diabetic patients. Severity, improve patient’s sensory function, reduce peripheral arterial occlusive disease, and allow patients to better control blood sugar, so scraping is considered to have good prospects in reducing symptoms of peripheral neuropathy, a complication of diabetes, but needs to be Larger studies will be needed to fully confirm.

Gua Sha is not just scraping, people, time and precautions should not be ignored.

People who are contraindicated in scraping:

1. Pregnant women and children under 1 year old.

2. Bleeding-related diseases, such as leukemia, hemophilia, and abnormal platelet coagulation.

3. Liver and kidney insufficiency.

4. Diabetes, cardiovascular disease, cancer patients.

5. Taking anticoagulant drugs.

Contraindications after scraping:

After scraping, pay attention to keep warm, and do not eat cold or blow dry.

It is not advisable to take a bath within 30 minutes after scraping.

After scraping, you need to wait for the scraping to completely subside before you can scrape again.

Add warm water after scraping.

It is not recommended to scrape every day to avoid muscle damage and fibrosis.

For the elderly and frail, young children over 1 year old or people who are sensitive to pain, Gua Sha only needs to be gently scraped. During the scraping process, if someone feels dizzy, such as dizziness, chest tightness, nausea, vomiting, cold sweat, weakness of limbs, etc., please stop scraping immediately, keep warm and rest and consider seeking medical assistance.

The darker the scraping color, the better? This is a misunderstanding

Some people think that the color of Sha should be as dark as possible, so that it is effective! So when scraping, they tried their best to suck up the milk, trying to scrape purple-red marks on the body, but this is a misunderstanding of scraping.

It is true that in traditional Chinese medicine treatment, the color of scraping is used to judge the condition. Generally, the darker the color of scraping, the blood is blocked, so the disease is severe and the pain is strong . The occurrence of Sha has a lot to do with the individual’s physique. Some people will not have Sha no matter how much they shave, and some people will get purple and red when they shave.

If you insist on scraping deep red and purple, resulting in improper scraping, the scraping may not be sha, but the redness and swelling of the microvascular rupture or the injury of the subcutaneous tissue, resulting in bruises, which may even cause skin infection or muscle fibrosis. It’s not worth it!
