Recently, in many places across the country, many people infected with the new coronavirus have gradually turned negative and returned to normal life and work. News circulating on the Internet that some infected people were hospitalized or died due to strenuous exercise in a short period of time after recovery, has caused a new round of worries among "yangkang people". So, how long after "Yangkang" can I exercise? How to exercise scientifically and effectively?

Will strenuous exercise cause sudden death after recovery from the new coronavirus?

Expert: You can first do soothing exercises such as Yi Jin Jing.

According to Xinmin Evening News, "It is widely spread on the Internet that it is particularly important to keep warm and windproof for half a month or even a month after the fever subsides. According to online news, someone went hiking and played badminton immediately after recovery, and unfortunately died ." In this regard, Chief Physician Pan Hongying, director of the Department of Infectious Diseases of Zhejiang Provincial People's Hospital, said that this issue is indeed worthy of everyone's attention. After infection, virus will invade different parts of the human body, including the heart. Strong exercise may put extra burden on the heart, which may cause myocarditisand other diseases.

In addition, Chief Physician Pan Hongying said that we should be especially careful about viral myocarditis among young people recently. The mortality rate of this disease is over 70%. Myocarditis is inflammation of the myocardium. Symptoms include shortness of breath, chest pain, decreased exercise tolerance, and irregular heartbeat .

The course of the disease may last from hours to months, with serious complications such as cardiac arrest due to dilated cardiomyopathy or heart failure. If you have palpitation, chest tightness, shortness of breath and other discomforts, you need to be more vigilant. It is recommended to seek medical treatment in time and have an electrocardiogram and blood test. Generally, young people who like to stay up late are more likely to get fulminant myocarditis. If not detected early, it can easily lead to cardiac arrest , multiple organ failure, etc. It is recommended to rest, get more sleep, and refrain from strenuous activities within two weeks after infection.

If you are isolated at home alone, it is best to keep in touch with your relatives and friends around you at all times so that you can go to the hospital in time if you feel unwell.

Will strenuous exercise cause sudden death after recovering from COVID-19? Feng Suiling, director of the Department of Traditional Chinese Medicine and respiratory expert at Peking University People's Hospital, told the People's Daily health client that this situation is an isolated case and may be related to myocarditis.

"The new coronavirus may cause infection complications other than the respiratory system. Among them, viral myocarditis is a more common complication." Feng Cuiling reminded that if you still have chest tightness and breathlessness within a week after turning negative, especially children and young adults who get worse after a little exercise, myocarditis needs to be ruled out in addition to respiratory diseases. This can be ruled out by doing an electrocardiogram and checking cardiac enzyme .

"COVID-19 patients will feel very tired. After the fever symptoms disappear, they can gradually do some soothing exercises, such as Baduanjin , Yi Jin Jing, etc." Feng Cuiling reminded, "It is helpful for patients to start appropriate exercise during the recovery period to promote recovery. The key is to master the 'degree' according to the individual's physical condition. Do not exercise vigorously, and do not hide and stay still."

Li Tong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital and a medical expert at Xiaotangshan Fangcang Hospital, also reminded in an interview with a reporter from Beijing Youth Daily on December 20 that it will take a week or two for many people to return to their previous physical condition after recovering from COVID-19. It is recommended not to engage in strenuous exercise yet. Some recovered people will still feel a little tired, even dizzy, and their physical condition is still not as good as before when they return to work and immediately engage in intense and busy work. It is recommended not to exercise strenuously at this time, but to gradually return to the previous level of activity and workload. Do not rush for success, and do not think about immediately making up for the previous work or making up for the missed sports and fitness activities. Once you are tired, take a rest as soon as possible.

32-year-old doctor fainted due to high fever and passed away

Experts remind: It is not recommended to be isolated alone

According to Beijing News, recently, Sichuan Jianyan Hospital32-year-old Dr. Wang Teng died in isolation alone due to infection with the new coronavirus.It is reported that after Wang Teng was infected with the new coronavirus, he was worried that his family would be infected by him, so he isolated himself at home. After he had a high fever and fainted, there was no one to take care of him, and he died without being sent to the hospital in time.

"Both adults and children may suffer from high fever and fainting." Zang Xuefeng, deputy chief physician of the Department of Critical Care Medicine at Beijing Millennium Monument Hospital affiliated to Capital Medical University, said that high fever may cause convulsions, aggravate cerebral ischemia in a short period of time, and cause cerebral edema2, which will affect the mind, lead to serious complications, and even be life-threatening.

"In the human brain, the braincase plays a role in limiting brain volume. When severe edema is caused by high fever and hypoxia, severe intracranial hypertension will occur, and even brain herniation will occur." Zang Xuefeng pointed out that people can take oral medications to relieve high fever and fever. Burn medicine, or use physical cooling methods to assist treatment, such as using warm water to wipe the forehead, armpits, chest, palms and other heat-dissipating parts. Do not "cover", otherwise it may cause the body temperature to get higher and higher. When the body temperature reaches a certain level, febrile convulsions are prone to occur.

Zang Xuefeng reminded that people who had febrile convulsions in childhood and special groups such as those with a history of epilepsy are susceptible to febrile convulsions. "Although children are more prone to febrile convulsions due to their tender body tissues, adults are often less tolerant to elevated body temperature than children." After people develop high fever, if the fever-reducing effect is still not achieved 2-3 hours after taking antipyretics, they should go to the hospital as soon as possible..

" It is not recommended that people quarantine at home alone after being infected with the new coronavirus . Try to ensure that there are family members around to take care of them. If conditions do not allow, family members should keep in regular contact with the person who is quarantined at home alone to understand Quarantine at home htm The latest changes in L2 patients. "Zang Xuefeng pointed out that in the epidemic environment, when medicines are prepared, one should also calm down and face the infection scientifically. After high fever, you can drink light salt water, salty soup, etc., and replenish fluids in time.

In addition, Tian Rong, deputy chief physician of the Department of Respiratory Medicine at Beijing Geriatric Hospital , also reminded that if children have difficulty breathing and shortness of breath, accompanied by nasal flaring and three concave signs, it is likely that the new coronavirus infection causes severe pneumonia and they need to be treated in time. For patients with high fever infected by the new coronavirus, the body temperature can generally drop to normal within 3 days. If the body temperature is still higher than 3 days after symptomatic treatment at home,

38.5 degrees Celsius, you need to see a doctor in time ; patients with underlying diseases need to see a doctor in time if they have clinical manifestations of aggravation of the underlying disease; child patients who have drowsiness, convulsions, refusal to eat, diarrhea, vomiting, and are not relieved by symptomatic treatment for more than 2 days need to be treated in a timely manner; pregnant women who have headaches, dizziness, heart palpitations, shortness of breath need to be treated in a timely manner.

What should I do if I have COVID-19 and keep coughing?

Recently, as the number of new coronavirus infections continues to rise, although the pathogenicity of Omicron has significantly decreased, many people still experience clinical symptoms such as cough, fever, muscle aches, and sore throat. In particular, some infected people still have coughs after turning negative, and they can't help but worry about whether their condition has worsened.

On December 23, Wang Gang, deputy director of the Department of Respiratory and Critical Care Medicine, West China Hospital of Sichuan University, explained the differences between cough after COVID-19 infection, common cold cough, and influenza infection cough, and how to deal with them.

Question 1: Is the cough caused by COVID-19 the same as the cough caused by a common cold?

Wang Gang: After being infected with the new coronavirus, cough symptoms often appear, which are different from ordinary infectious coughs, colds, and even influenza coughs. The reason is that the new coronavirus is neurophagic and can easily lead to neuropathological and inflammatory changes. For example, leading to hyposmia or taste loss is actually pathological damage to our vagus nerve . Therefore, the cough after new coronavirus infection will be more severe and longer-lasting than the cough caused by common cold and flu-related infections.

Question 2: Do I need medication if I keep coughing after being infected with COVID-19?

Wang Gang: Some peripheral and central antitussive drugs can usually be used, and different drugs should be taken according to the acute, subacute and chronic stages. For cough caused by COVID-19 infection in the acute stage, antitussive drugs cannot be used alone. Antitussive amine drugs and decongestants need to be combined with the treatment. During the fever stage, it also needs to be solved with antipyretic and analgesic drugs. Subacute and chronic cough after COVID-19 infection are treated in accordance with the standards of the "Chinese Cough Diagnosis and Treatment Guidelines". Antitussive drugs can be given, such as Asme, Huifein, dextromethorphan, etc. These traditional Chinese medicine prescriptions can also be considered.

Question 3: If I have phlegm when I cough, can I use phlegm-reducing medicine or even antibiotics ?

Wang Gang: needs to be based on the color of expectoration sputum. This is very important. Normally, COVID-19 infection leads to increased mucus secretion, and the sputum is usually white. If the sputum is white, although it is abundant, but it is easy to cough up, you do not need to add phlegm-reducing drugs . However, if the color of the sputum changes from white to yellow or even golden sputum, you need to be alert to the combination of viral infection and bacterial infection, and you need to combine it with antibacterial drugs. Patients who have no special medication requirements or a history of drug allergies can choose penicillins and cephalosporins. The general course of treatment is 5 days.

Question 4: I find blood streaks in the sputum when I cough. Is there a serious problem with my body?

Wang Gang: If the patient has not coughed up blood in the past, but this time he coughs up blood after being infected with the new coronavirus, if there is blood in the sputum and the blood is on the surface of the sputum, then it is just mucosal damage. There is no need to be nervous about this situation, just observe it. If the blood and sputum are mixed evenly, it means that the hemoptysis may come from the lower respiratory tract, or it may be in the bronchioles, alveoli, and . If the amount of hemoptysis continues to increase and turns bright red, it is recommended that relevant examinations be performed and that you go to the hospital for treatment.

Question 5: How long will the cough last after COVID-19 infection?

Wang Gang: In the acute stage, about 60% to 80% of patients will have a cough, which can generally be relieved naturally. When the cough is in the subacute stage, that is, after three weeks, if the cough is still not relieved, it is usually recommended to go to a specialist for further treatment.

New crown "burned out" hyaluronic acid ? Experts explained

"I gritted my teeth and took the two injections with tears, but the result was that Omicron burned me out." Recently, some consumers who had used hyaluronic acid for beauty treatments suddenly found that their originally smooth and plump faces had been "returned to their original shape" after being infected with COVID-19 and had a fever, triggering heated discussions in the market.

According to the Financial Associated Press, many experts interviewed by the reporter said that under normal circumstances, the sustained high fever after COVID-19 infection will cause the body's local temperature to rise, which will accelerate the absorption and metabolism of hyaluronic acid to a certain extent.. This matter may affect recent consumer behavior and hyaluronic acid sales, but in the medium to long term, demand for hyaluronic acid supplements may also increase after the peak of COVID-19 infections.

"I spent so much money on injections that were in vain, I feel so sad!" Such "experience sharing" has become common on Xiaohongshu recently.

According to reporters from the Financial Associated Press, hyaluronic acid in the medical beauty industry is an injectable hyaluronic acid (HA) dermal filler. It is a glycosaminoglycan composed of D-glucuronic acid and N-acetylglucosamine. Its immunogenicity is extremely low. Artificial injection of hyaluronic acid to fill subcutaneous tissue has good biocompatibility and usually does not cause inflammation and allergic reactions in surrounding tissues, which makes it the preferred material for biofilling. Therefore, hyaluronic acid is very commonly used in facial rejuvenation and cosmetic medicine, and it is also one of the most popular medical beauty products .

Regarding the "disappearance" of hyaluronic acid after fever, a reporter from the Financial Associated Press consulted Huang Yiming, director of the China Plastic Surgery Association.She said that from a clinical perspective, hyaluronic acid or other materials filled with are themselves absorbable materials. However, due to individual differences, the absorption and metabolism are also different. Generally, it can be fully absorbed and metabolized in 8-12 months. When the temperature of the tissue increases, the process of metabolic absorption may be accelerated. "Theoretically, high temperatures have the possibility of accelerating the metabolism of hyaluronic acid. And if the human body continues to have a high fever, the metabolism and absorption of hyaluronic acid will be accelerated to a certain extent." Pang Dongsheng, general manager of Shenzhen Damei Xinrui Medical Cosmetology, also agreed with this. He told a reporter from the Financial Associated Press that if the hyaluronic acid is administered by a regular institution, there is a certain probability that the body's absorption will be accelerated if the body continues to have a high fever. "Strictly speaking, is not burned out, but the metabolism is accelerated."

"If consumers choose an irregular institution, they may be given some products that are not real 'hyaluronic acid' by personnel without professional qualifications, and they may be lost quickly even if they don't have a fever." Pang Dongsheng added.

Dr. Yang Cuixia, a New Oxygen Emerald doctor and chief physician of Xinlimei Medical Aesthetics of Sichuan Provincial People's Hospital, interpreted this phenomenon from different angles. She told reporters from the Financial Associated Press: During the epidemic, everyone's rest and diet are often affected, and the consumption of their own collagen caused by the disease may be greater. Although rising body temperature will accelerate the body's metabolism , the retention of hyaluronic acid under the skin cannot be directly judged by the naked eye. After hyaluronic acid enters the subcutaneous tissue as a filler, its metabolism is related to the cross-linking links between hyaluronic acid molecules. It usually has a metabolism period of more than half a year. The metabolism rate of hyaluronic acid in different brands, different processes, and different parts will be different, and the retention time will also be different between the first injection and multiple cumulative injections.

Huang Yiming also further explained that the hyaluronic acid to be filled depends on the specific product characteristics, such as whether it is biphasic hyaluronic acid or monophasic hyaluronic acid. The metabolism time of the two is also different, and doctors will also use it in different parts when injecting. In biphasic hyaluronic acid, there are more single molecules of free hyaluronic acid, which will be metabolized and absorbed by the body first. The hardness is relatively natural and soft. It is suitable for filling the apple muscles, nose base and other parts. The probability of accelerated metabolism is greater under high fever. There is also a type of single-phase hyaluronic acid, which is mainly used for body shaping and has a higher hardness. The cross-linking of hyaluronic acid is higher and tighter, and it is generally not easily metabolized and absorbed in a short period of time.

Yang Cuixia also reminded that the retention of hyaluronic acid in the body after injection and filling is not as fragile as everyone thinks. In the early stage, the hyaluronic acid molecules are closely linked, but in the later stage, the hyaluronic acid molecules will be relatively loose, and the metabolism rate of each part is also different. "We advocate moderate and reasonable regular supplementation to maintain youthfulness."
