【推荐1】Do you suffer from low energy? Is it difficult to get out of bed in the morning? Do your head and stomach ache? If so, you could be experiencing job burnout.     1    —77% of workers surveyed by Deloitte said they had experienced burnout. And 90% of those said that stress had negatively impacted their work.

Burnout is dangerous. It can lead to mental and physical exhaustion, a loss of identity, and feeling a lack of accomplishment, they harm the body over time. Do you want to get out of this state?     2    

One way you can help relieve burnout is by practicing communication. Be clear about what you’re feeling, and if you are being overworked, discuss it with your supervisor or coworkers.     3     Taking time off is also a good idea.

While self-care is trending these days, it will not cure burnout.     4     Their support and cooperation can make you feel better. Another option is taking part in regular physical activities to get your mind off work.

    5     A study cited by The New York Times found that surgeons who made time for recreational activities were less likely to experience burnout than those who didn’t. A few ideas for relaxing activities can be yoga, meditation, or mindfulness.

【推荐2】Imagine your mind as a library. As pleasant a room as a reader could wish. Now let me describe different sort of library: The bookcases have fallen, their glass fronts broken, and their contents messed across the floor. This one belongs to the disordered, anorexic(厌食) mind. At the age of 15, 3 was the state of my mind. For 10 years, I suffered the mental and physical pain of anorexia.

A new year usually made me nervous: A time for resolutions. In January 2019, I was 24. Ten years after diagnosis, I was what doctors call a “functioning” anorexic. I would eat enough to get by: never with any flavor. That year, I made a different sort of January resolution: To read all novels Dickens by December. Something changed, I began to be curious about food, wanting to share it, taste it. His scenes, his meals made me hungry. It also turned me into a walker. I wanted to see London as he had seen it: At night, on foot.

Siegfried Sassoon also rescued me.The poet recalls cold mornings before a hunt: “We got up at four o'clock, and fed ourselves with boiled eggs.” Stopping in a bush, he has sandwiches , and on the way home he keeps himself warm with thoughts of poached eggs on toast, tea...All those eggs! All that bread! Hot chocolate! (I hadn’t had a cup of hot chocolate in a decade.) With Sassoon as guide, I learnt, at the age of 25, to boil an egg.

Most helpful to my recovery were the words of the wizard Merlyn in T. H. White’s The Once and future King. “The best thing for being sad,” he tells the boy who will become King Arthur, “is to learn something. That is the only thing that never fails. . . ” Too many self-help guides say: Get fit, lose weight, eat right, make friends, find a hobby. . . Better that they should say: Learn something, read something, see something new. Feed your mind.Trigger your appetite for new books, and the other appetites-for food, for friends, for life-will follow.

Eating healthfully is important to maintain one’s health. I try to avoid foods high in fat like French fries or cookies. I also try to limit the amount of animal protein I consume.     2     So, it is important to know how to cook these foods so that the nutrients are not lost in the cooking process.

Our muscles must continue to be strong to support our body as we age. Exercise helps the bones build density and helps us maintain our posture.     3     A regular exercise program of cardiovascular training and weight training is an important part of keeping us healthy.

    4     Studies have shown that people with a wide range of social contacts get fewer colds and recover faster from diseases than those who aren’t socially active. For the sake of health, I like to play and interact with my friends and I always feel better when I am with them than when I am alone.

By eating properly and exercising regularly, I can keep my body at an appropriate weight and can maintain my health. By spending time with my friends, I can keep my mind as well as my body happy.     5    

【推荐1】Swimming in freezing water may sound hard to understand. But that's precisely what 400 athletes from 33 countries had to endure in the 3rd International Ice Swimming Championships held in Murmansk, Russia from March 14 to 17, 2019.

Unlike normal swim competitions, ice swimming doesn't suit everyone. The extreme sport can damage the heart. So even the most experienced athletes are carefully monitored and medically examined before and after they enter the water. Individual spotters are assigned to each participant to check for any issues as they swim. Each event also has a strict time limit after which competitors who are still in the water are pulled out.

As a rule, participants don't dive in. Instead, they dip themselves into the water slowly using adders, allowing the body to get gradually accustomed to the low temperature. Swimmers must also stay horizontal（水平的）in the water at all times and aren't allowed to perform flip turns（滚翻转身）. That's because, in cold water, the warmer blood moves to the core（核心）of the body, protecting the organs from the extreme temperature. A flip turn could lead warm blood to move and endanger the organs.

Upon completing their race, swimmers are quickly led to a recovery center, where experts help them warm up by dipping their legs in cool water and covering their bodies with heated towels. Once their body temperature stabilizes, the swimmers settle down into a hot bathtub.

Despite risks, many ice swimming addicts still enjoy participating in ice swimming competitions. They like the physical challenge of actually swimming in freezing water and swimming distance. Besides, they love the feeling of being out in nature.

【推荐3】Tiny, black-capped chickadees (北美山雀) have big memories. They store food in hundreds to thousands of different locations in the wild—and then come back to these places when other food sources are low.

Scientists have known that chickadees have incredible memory skills. That memory can be a matter of life or death for these birds when there are no enough food resources in colder months.

Some researchers thought that neurons called place cells (细胞) would explain these birds’ ability to remember where their food is stored. These cells are known to include information about where things are in space. But recently, Selmaan Chettih and his team found that each time a chickadee hides a seed (种子) in a specific location, a unique brain pattern appears—separate from place cells.

To observe this, Chettih and his team created special areas with lots of feeders filled with sunflower seeds. They put small flaps (片状下垂物) where birds could hide seeds.

The scientists tracked the activity in their brains. Each time a bird hid a seed under a flap, researchers saw a brief unique brain pattern appear—what they called the bar code. Different patterns appeared even if the birds hid many seeds in the same location. When the birds revisited these sites and retrieved the hidden seeds, the same bar code-like pattern appeared again, as though all the information about each location and seed were related to a unique brain pattern.

The researchers compared these memories to episodic memories in humans, which are memories of specific events or personal experiences. They’re important to how humans connect time, people, places and sensory information together.

Chettih says that this seed-hiding behavior has a clear pattern of activity, which may help researchers build a structure for how the brain creates and stores memories.
