We’ve certainly seen a dog nursing a wound, or a deer calling out in pain. But many animals suffer in silence. The most silent sufferers in the animal world may be fish.
Do fish feel pain? A new study from the University of Liverpool has found that fish feel pain in a way that’s “strikingly similar” to humans. For the study, Lynne Sneddon, from the university’s Institute of Integrative Biology, reviewed the existing body of research-98 studies in all-and concluded that they feel pain just as sharply as we do.
“When subject to a potentially painful event, fish show changes in behavior such as stopping feeding and reduced activity, which are prevented when a pain-relieving drug is provided. In fact, like us, they breathe heavily and stop eating when they’re hurting. They will even rub the part of their body that aches.” Sneddon notes in a university release.
To understand pain in other species, scientists look at nociceptors, which send signals to the brain when the body is being damaged. Humans have them throughout their skin, bones and muscles. Nociceptors have also been found in many other species, including even those tiny fruit flies. Fish have the same means to detect pain signals and the equipment to receive them.
Besides, the fishermen’s opinion that fish feel no pain just doesn’t add up from an evolutionary view. Pain is an efficient messenger that tells us that we’ve got a problem. An animal that can’t feel it won’t get that memo(备忘录), even if it hurts itself.
“If we accept fish experience pain, then this has great significance for how we treat them,” Sneddon says. “Care should be taken when handling fish to avoid damaging their sensitive skin and they should be humanely caught and killed.”

When I finished all of my exam, my family drove to the countryside for a holiday. On our way, my favorite scarf flew out of the window suddenly and is gone. I felt very sad, regretting that when I hadn’t kept the scarf well. Soon after, we stopped at a service station. Feel upset, I found a bench and was about to ate my sandwich when a motorcyclist pulled into the station, “Is that your blue car?” he asked me. Although I felt surprising, I nodded quickly. A man pulled out the very scarf from my backpack and handed it to me. He then returned his motorcycle and wanted to leave. I went up and repaid him thankful by giving him a hug.

Imagine that a close friend ignores you when you arrive at his party. 1. But if you think about the situation differently, you would calm down. Using a particular emotion management strategy called reappraisal, which involves viewing an upsetting event in a positive light, is often effective in contributing to positive outcomes.
2. The research showed that if people believed feelings were malleable (可塑造的), they used reappraisal more frequently, and in return they had greater emotional health and life satisfaction.
University of Toronto researcher Brett Ford and her colleagues did another study. 3. The researchers found that the youths who believed emotions were controllable used reappraisal more and were less depressed than those who didn’t.
Does accepting our feelings impact our well-being? 4. In one research, the researchers stressed out participants by requiring them to give an impromptu (即兴的) talk. In another research, people kept daily diaries about how they handled stressors (紧张性刺激). In both cases participants who accepted their feelings experienced less negative emotions than people who judged their feelings.
“However, while emotions may be changed with efforts, that doesn’t mean they’re completely controllable,” says Eric Smith of Stanford University, “we shouldn’t expect to completely avoid or immediately remove certain of feelings. 5.”
A.It found a similar pattern.
B.You would be angry or upset, right?
C.We have beliefs about our emotions.
D.According to Ford and her colleagues, it does.
E.But we can learn to reduce them in hard times.
F.They were also less depressed and more satisfied with life.
G.Now, new research suggests our beliefs about our feelings affect us greatly.
People often think that blue light before bedtime can make it harder to sleep. It’s true that the screens on phones, computers and televisions send out plenty of blue light. But if you’re focused on blue light as a major problem affecting your sleep or your eye health, it’s time to look at it from another aspect.
As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It’s part of sunlight, and your eyes are exposed to plenty of it all the time. You’re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well—so in a sense, we already have built-in blue blocking protection.
Adding more protection isn’t likely to help, though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money. These products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.
The American Academy of Ophthalmology doesn’t recommend blue-blocking products, either. Instead, if you’re concerned about your eye health or your ability to get to sleep on time, you already know what to do.
Put the screens away at bedtime. Read a book or find something else to do. While you’re using screens, take a 20-second break every 20 minutes to look at something 20 feet away (the “20-20-20” rule). If you get dry eyes when you look at screens for a long time, use eye drops labeled artificial tears.
