Conflict is on the menu tonight at the café La Chope. This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France's favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn't always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,' or ‘people think',” Lehane told them. “Say ‘I think,' ‘Think me'.”

A café society where no intellectualizing is allowed? It couldn't seem more un-French. But Lehanne's psychology café is about more than knowing oneself: It's trying to help the city's troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation's desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.

The city's psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne's group just to learn to say what they feel. “There's a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she'd like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn't exist”, she says, “If life weren't a battle, people wouldn't need a special place just to speak.” But them, it wouldn't be France.

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers 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 researchers 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 bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. 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 expression. 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.

    US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).

    National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water — given to the food industry in the US — held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.

    Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”

    However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.

    In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various ways to make sure each surface of each hand is clean.

    Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers, hoping to sell their products.

    'The endless choice gives birth to anxiety in people's lives. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors.

    It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing; no choice, no anxiety.

    Move over, helicopter parents. "Snowplow(扫雪机) parents" are the newest reflection of an intensive(强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don't sleep through a test, and even calling their kids' employers.

    Helicopter parenting, the practice of wandering anxiously near one's children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children's path to success, so they don't have to suffer failure, frustration(挫折)or lose opportunities.

    It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.

    Rich parents may have more time and money to devote to making sure their children don't ever meet with failure, but it's not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.

    Yes it's a parent's job to support the children, and to use their adult wisdom to prepare for the future when their children aren't mature enough to do so. That's why parents hide certain toys from babies to avoid getting angry or take away a teenager's car keys until he finishes his college applications.

    But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?

    "Solving problems, taking risks and overcoming frustration are key life skills," many child development experts say, "and if parents don't let their children experience failure, the children don't acquire them."

    Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend's house or in a hotel room, and find it difficult or impossible to fall asleep. Is it because the bed is uncomfortable? Maybe, but perhaps there can be other reasons.

    According to a new study published in Current Biology, a significant reason is what the scientists call "first night effect". They believe that one side of the brain acts as a "night watch" to warn us about potential dangers. It forces us to stay awake on the first night in a new environment.

    For the study, 35 young volunteers were asked to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.

According to the researchers, on their first night, the left brains were more active than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, falling even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.

    The findings suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. Thus, the brain can't relax and is sensitive to anything strange in the surroundings, just as it is in daytime.

    "At some level, the brain is continuing to analyze things, even though you are not aware of the analysis," US professor Jerome Siegel told Smithsonian Magazine. "If something unusual happens – if a door opens or you hear a key in a lock – you can be alert, even though the intensity of the stimulus is quite low."

    More surprisingly, this phenomenon is similar to the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake, with its corresponding eye staying open.

    The researchers think that it is the result of evolution, and works to protect us in potentially dangerous environments.

    If you have ever had what you think is "first night effect", researchers suggest that you bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.
