【推荐1】How COVID-19 Affects Your Body

What COVID-19 Can Do

Doctors continue to learn about the short-term and long-term effects of COVID-19 on your body. For some people, It starts with basic flu symptoms. But it could eventually affect your lungs, liver, kidneys, and even your brain.

How It Spreads

Usually the virus makes contact with you when a nearby infected person sends droplets(微滴) into the air by coughing, sneezing, or talking. It spreads easily between people within about 6 feet of each other. An infected person can spread these droplets, even if they don’t feel sick. The virus may infect you after you touch an object, like a doorknob(门把手), that has the virus on it. But that's not as common.

Main Symptoms —Upper Respiratory Infection（上呼吸道感染）

Once the virus enters the body, it usually settles in the cells that line your nose, sinus cavity(鼻窦腔), and throat. For most people, this is where it stays. Symptoms often follow, but you may not feel anything for up to 2 weeks, as the virus starts to invade(侵略) healthy cells and reproduce. You can transmit (传播) it to others even if you don't show any symptoms.

Other Common Symptoms

The first symptoms that typically appear include a fever, headache, sore throat, and dry cough. But what you'll feel can vary widely in this early stage. You may also have:

●Shortness of breath
●Chills, fever, body aches
●Loss of sense of smell or taste
●Unusual tiredness
●Stuffy(不通的) or runny nose
●Nausea or diarrhea
No Symptoms?

Some studies show that up to 40% of people with COVID-19 are “asymptomatic(无症状的).” That means they don’t feel sick or have symptoms. But the virus can still affect your body. X-rays and CT scans of some people without symptoms show lung damage including “ground-glass opacities,”a typical lung lesion(损害) in people with COVID-19.

【推荐3】A woman in Zhejiang Province has been told by the doctor that she might develop “dead butt syndrome” (死臀综合征) due to long periods of sitting, according to a report by Guangming Net on Wednesday. The 26-year-old woman, who prefers to be called Dai, had been experiencing discomfort in her lower back for the past two months. The discomfort later became unbearable pain during extended periods of sitting.

News of the incident quickly gained attention on Sina Weibo. Some users humorously commented that while some people may be alive, their butts have already “died”. Others expressed concern about their own inactive lifestyles and the possibility of developing the syndrome.

“Dead butt syndrome” mainly happens when the gluteus medius (臀中肌), one of the three main muscles in the buttocks, weakens due to long periods of sitting. This weakening can damage the muscles’ability to work properly, leading to poor shock absorption and reduced motion control of the hip and leg. The syndrome is becoming a more common disease without people’s noticing.

Medical professionals have offered precautionary (预防的) measures for the syndrome, stressing the importance of staying physically active. For individuals who sit for long periods, it is recommended to stand up and stretch the body periodically, walk around, and keep the gluteal muscles active throughout the day.

A simple rule to follow is to stand up and move for at least 10 minutes every hour of sitting to reactivate the gluteal muscles and prevent them from becoming “inactive”.

There are three simple self-diagnosis (自我诊断) steps for the syndrome: flat and floppy butts, discomfort in the waist, hips, and knees after long time of sitting, and an inability to keep the upper body upright while performing a deep squat (蹲) with both hands extended overhead. If someone shows all these symptoms, there is a possibility that they have developed the syndrome. Furthermore, if individuals experience worsening lower back pain after long periods of sitting, seeking professional medical help is advisable.

【推荐3】On James Owen’s 70th birthday, he saw a video of himself walking with difficulty up to the stage where he was giving a talk. “I looked like an old man,” says Owen, who built a successful career on Wall Street.

He was about 25 pounds overweight and had chronic trouble with his back, knees, and shoulders. But instead of giving in to age, Owen decided to set an ambitious five-year goal: He wanted to be pain-free, and he decided the way to get there was through exercise —even though at the time he couldn’t do a single push-up.

Owen began his new exercise regimen (养生计划) by walking, though he became out of breath after five minutes. But that didn’t discourage him. He kept at the walks every day, along with some stretching. Once he had those basics down, he started weight lifting and hired a personal trainer to teach him and to design a routine he could follow on his own. The last piece was finding other activities he enjoyed, which turned out to be cycling and swimming.

In less than five years, Own was able to do three sets of 50 push-ups each and walk for miles each day. And yes, he was free of aches and pains.

Owen used his experience to write a book called Just Move! A New Approach to Fitness After 50, in which he details how older adults can safely get off the couch and add more movement to their lives. The key: getting started, even if you walk just three blocks, which was all he could manage at first. “Think of it as movement, not exercise,” he says. “The key is slow and steady progress.”

Now 81 and retired, Owen exercises an hour a day, six days a week. “It is the best investment I’ve ever made in my life,” he says.
