Stressed About Coronavirus? Monitor Your Body Language
The Centers for Disease Control and Prevention (CDC), and other health professionals, have maintained that the recent coronavirus can be spread by touching people or surfaces infected by the virus, and then touching your face-particularly your mouth, nose, and eyes, where the virus can gain access to your body. No doubt, fears of this potentially deadly virus is causing people around the world a great deal of stress. 1.
You may have seen clips of health professionals warning about face-touching in press conferences, but then absent-mindedly touching their own faces-even licking a finger to turn a page on their written speeches! 2. Unfortunately, stress can increase the incidence of face-touching behavior.
A common body reaction to stress is self-touching. Some of that might consist of chin or cheek rubbing, which can bring infected fingers dangerously close to the mouth. Of course, there is also nail-biting, which provides the virus with direct access to the mouth.
Research on nonverbal signals of lying has focused on common body language signals connected with stress. 3. Stress from telling a lie has been associated with people touching their noses or faces. It has been suggested that temporary increases in tension or stress-such as when someone is telling a lie-may cause the nose to itch (发痒). This leads to response of scratching or rubbing the nose
Stress may also lead to dry eyes, mainly because the automatic reaction to fear-induced stress is to widen the eyes and blink less frequently, thus drying out our eyes. Our responses can include eye rubbing behavior-opening the way for the virus to enter our bodies.
Don’t get me started talking about greetings. 4. However, greeting behaviors such as touching hands (handshaking), cheek-kissing and hugging all open the door for viral transmission (病毒传播). Moving to more safe forms of greeting -waves, fist-bumps, or even bowing-should become the norm during these troubling times.
5. We need to become more aware of our nonverbal behavior and go into social situations more mindfully.
A.To sum up, what should we do?
B.Some of these same signals could lead to infection.
C.It is probably because they have been under too much stress.
D.In other words, nonverbal signals of stress might lead to infection.
E.That is why people may touch their noses or faces when telling a lie.
F.In social gatherings people almost automatically extend their hands or hug.
G.What’s worse many of our unconscious reactions to stress can lead to infection.
Contemporary worries about the impact of technology are part of a historical pattern. The new technologies that dominated the past decade seem to be making things worse. Parents worry that smartphones have turned their children into screen-addicted zombies. The technologies expected to dominate the new decade also seem to cast a dark shadow. Artificial intelligence (AI) may well deepen bias and prejudice, threaten your job and shore up authoritarian rulers.
Today’s gloomy mood is centred on smartphones and social media, which took off a decade ago. Yet concerns that humanity has taken a technological wrong turn, or that particular technologies might be doing more harm than good, have arisen before. Stand back, and in these historical cases disappointment arose from a mix of unrealised hopes and unforeseen consequences. Technology frees the forces of creative destruction, so it is only natural that it leads to anxiety: for any given technology its drawbacks sometimes seem to outweigh its benefits. When this happens with several technologies at once, as today, the result is a wider sense of techno-pessimism.
However, that pessimism can be overdone. Too often people focus on the drawbacks of a new technology while taking its benefits for granted. Worries about screen time should be weighed against the much more substantial benefits of instant communication and access to information and entertainment that smartphones make possible. A further danger is that efforts to avoid the short-term costs associated with a new technology will end up denying access to its long-term benefits—something called a “technology trap”. Fears that robots will steal people’s jobs may prompt politicians to tax them, for example, to discourage their use. Yet in the long run countries that wish to maintain their standard of living as their workforce ages and shrinks will need more robots, not fewer.
That points to another lesson, which is that the remedy to technology-related problems very often involves more technology. And the most important lesson is about technology itself. Any powerful technology can be used for good or ill. Biotechnology can raise crop yields and cure diseases, but it could equally lead to deadly weapons. Technology itself has no agency: it is the choices people make about it that shape the world. Thus the techlash (技术鞭策) is a necessary step in the adoption of important new technologies. At its best, it helps frame how society comes to terms with innovations and imposes rules and policies that limit their destructive potential, accommodate change or strike a trade-off. Healthy skepticism means that these questions are settled by a broad debate, not by a group of technologists.
Perhaps the real source of anxiety is not technology itself, but growing doubts about the ability of societies to hold this debate and come up with good answers. In that sense, techno-pessimism is a symptom of political pessimism. Yet there is something comforting about this: a gloomy debate is much better than no debate at all. And history still argues, on the whole, for optimism.

Loneliness hurts. It is psychologically distressing and so physically unhealthy that being lonely increases the likelihood of an earlier death by 26 percent. But psychologists think it hurts so much because, like hunger and thirst, loneliness acts as a biological alarm bell.
On March 26, just as the COVID-19 pandemic gripped the world, researchers from the Massachusetts Institute of Technology posted a report on bioRxiv. It is the first study in humans to show that both loneliness and hunger share signals deep in a part of the brain that governs very basic impulses for reward and motivation. So, our need to connect is apparently as fundamental as our need to eat.
The researchers used functional magnetic resonance imaging (fMRI) to compare brain responses to loneliness and hunger. 40 adult participants underwent a 10-hour session depriving (剥夺) them of food and another 10-hour session denying them social contact. Both sessions served as a control (对照) condition for each other.
The social-isolation condition was challenging to arrange. Some people are lonely in a crowd, while others enjoy solitude To induce(l t)not just objective isolation but subjective feelings of loneliness, the researchers had the participants spend their time from 9 A.M. to 7 P.M. in a room at the laboratory without phones, laptops or even novels in case fictional characters provided some social support. Puzzles were allowed, as was preapproved nonfiction reading or writing.
Researchers then focused on a midbrain region called “the substantia nigra”, a center of dopamine (多巴胺) release involved with motivation and desire. The dopaminergic response shows a strong wanting. In the scanner, participants saw images of their preferred forms of social interaction and of their favorite foods, as well as a control image of flowers. It was then found that the substantia nigra responded only to cues of what they had been deprived of. The magnitude of the response correlated with the subjects’ self-reports of how hungry or lonely they were, though the feelings of hunger were consistently stronger.
Finally, the researchers used machine learning to confirm their findings. A software classifier trained to recognize neural patterns during fasting (斋戒) proved able to recognize similar neural patterns from the social-isolation condition even though it had never “seen” them. So there seems to be an underlying shared neural signature between the two states.
Even before the COVID-19 pandemic, an obvious next question for the work was whether different forms of social media could satisfy the need for social connection. Those researchers were never able to get funding for such a study. But now it seems they will.

A lifesaving traffic stop
Kemira had just jumped in the shower when her mother Tammy banged on the door. Kemira’s 12-day-old daughter was _______. Having fed baby Ryleigh just 30 minutes earlier, the new mother burst out of the bathroom and began patting her daughter _______ the back. Ryleigh was usually quick to cry. Now she didn’t make a _______, “I’d been told to raise their arms when babies are choking, so I tried that, but she still was _______ to breathe,” Kemira said later. She knew Ryleigh needed to get to the hospital fast.
The three had barely _______ it out of their neighborhood when the flashing lights of a police cruiser appeared behind them. Deputy Will Kimbro figured that the _______ driver was either too distracted to notice him or simply unconcerned. Kimbro soon found out it was a frightening _______ of the two.
Once she’d _______ to the curb (路边), a frantic Tammy jumped out of the car, exclaiming that her granddaughter had stopped breathing.
Desperate for help, Kemira handed the baby to Kimbro. He put a hand on her little _______. Ryleigh’s heart was barely beating.
Kimbro radioed for a(an) ________—it was seven minutes out, and the hospital was even further away. That was seven minutes Ryleigh didn’t have, her lips already an ominous shade of blue.
Luckily, Kimbro had recently completed a CPR class and knew ________ how to treat a baby. “Although I was ________, my training kicked in, and I went to work to keep that baby ________,” says Kimbro. He gave Ryleigh to Kemira to hold, his hands busy as he checked for a pulse. Then he began tapping and kneading (揉) Ryleigh’s chest, hoping to massage her heart back into action. Thanks to the CPR class, Kimbro knew the choking baby didn’t have a ________ if there was a blockage, and he used one finger to clear her airway (气道). That was the magic touch; 20 seconds later, Ryleigh began to fuss. Then came a whimper.
“If she’s crying like that, she’s breathing,” said Kimbro. The ________ was obvious in his trembling voice. “________ she’s crying, she’s breathing.”
But they still had five more minutes until medical service would arrive, and Kimbro worried that Ryleigh would choke again. He continued with delicate chest compressions and periodically clearing her airway.
In the body camera footage, Kimbro can be heard ________ Kemira, the approaching sirens wailing in the background: “I didn’t feel a heartbeat earlier, so I started massaging her heart and now I feel it. It’s real strong now.”
