Almost all researches in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic (共鸣的). They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researches have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in had dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dream. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic express. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    Whatever happened to the familiar scene from the past of children playing "tag(捉人游戏)" in the streets while their parents chatted with the neighbors over the garden fence? This picture is fading fast today, as children are now leaving the streets in favor of a screen.

    Several organizations are attempting to change this situation. One of these organizations is Play England, which aims to improve opportunities for children to play outside. A leading figure in the campaign is 50-year-old Adrian Voce, who has childhood memories of days spent in the "Big Woods" near his house with his older brothers. "We were given a packed lunch and told not to talk to strangers. I can still remember wandering in and out of each others' houses." he says.

    However, it is not only the children that Mr. Voce and his organization have to convince. In many cases the parents themselves block his efforts. A survey in 2014 found that 85 percent of adults agreed that it was important for children to be able to play safely in the road or street where they live. However, many of them were not prepared to park their cars an extra 50 meters away from their homes.

    Mr. Voce's attempts to encourage children to play outside include the organization of campaigns like National Playday. Hundreds of communities all over the country take part in this effort, yet it can take a lot of people to give children a taste of what it is like to play in the streets. On one street in Aldershot last year there were five policemen, three community support officers, a traffic management crew, a closed-circuit television van, and a team of "play workers."

    Society today has changed to such an extent that children do not feel safe on the streets and their parents no longer feel comfortable about letting them play there. It is not only the appeal of computers and video games that has driven children inside, but also the presence of traffic, crime, and violent young people. However, thanks to the efforts of people like Adrian Voce, it may not be too late to turn back the clock.

    Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when wβfinally clean up our act.

    If the evidence for how wrong the first idea is isn't apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?

    To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.

    The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.

    The effects of some bad habits-smoking, in particular-can haunt you for decades. But the damage from other habits can be largely healed.

    “Any time you improve your behavior and make lifestyle changes, they make a difference from that point on.” says Dr. Jeffey Koplan. “Maybe not right away. It's like slamming on the brakes. You do need a certain distance.”

But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research: —A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month. —The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won't cure all that bothers you, of course. But doctors believe that many chronic diseases-from high blood pressure to heart disease and even some cancers-can be warded off with a few sensible changes in lifestyle.

    Not sure where to start? Surprisingly, it doesn't matter, since one positive change usually leads to another. Make enough changes, and you'll discover you've adopted a new way of life.

    Everyone likes living in a clean and comforting environment. If the environment are bad, it will affect our body, and make us not feel well. Sometimes we may be terribly ill. At that time we don't want to work, and we have to stay in bed and rest at home. So the environment is very important to us.

    It's germs that makes us ill. There are germs everywhere, They are very small and you can't find them with your own eyes, but you can see them with a microscope They are very small and there may be hundreds of them on a very small thing, Germs can always be found in dirty water. When we look at dirty water under the microscope, we shall see them in it. Germs can also be found in air and dust. If you cut your finger, some of the dust from the floor may go into it, and you will have much pain in it. Sometimes the germs will go into all of your body, and you will have pain everywhere.

    To keep us healthy, we should try our best to make our environment become cleaner and tidier. This needs us to act together.
