1 . It’s time for bed, the lights are out, and yet you’re wide awake. You do eventually manage to fall asleep, but even then, it’s a very shallow, restless sort of sleep.
Now more research suggests you needn’t look further than outside your window and at the moon for the cause of this sleeplessness. However, in a surprising twist, the findings weren’t entirely what the researchers expected. While we know that humans are a species ruled by light, the “lunar phase effect” (月相效应) affects sleep even when artificial sources of light are accounted for.
Rather than people staying up later and sleeping less during the full moon, it was just before the full moon that sleep was shorter and lighter. “It turns out that the nights before the full moon are the ones that have most of the moonlight during the first half of the night,” said Horacio Iglesia, a professor of biology at the University of Washington in The Guardian. The opposite was true just before the new moon — people tended to sleep more and go to bed earlier.
Ninety-eight participants across three Indigenous communities in Argentina wore wrist monitors tracking sleep patterns over the course of one to two months. While one community had no access to electricity, the second community had limited access, and the third community was located in an urban setting with full access to electricity.
The study also found that this lunar phase effect on sleep also appeared to have greater impact on people who had more limited access to electricity. In every community, participants’ peak (高峰) sleepless period occurred in the three to five days leading up to the full moon night, while the opposite was true for the new moon, the study authors found.
Wanting further insight, the researchers compared their data to the results of a similar study of 464 Seattle-based students at the University of Washington. The findings proved consistent.
This research supports the view that try as we may, we can’t ever fully get away from some forces of nature.

2 . Think about all those successful people in your life that you know. How many of them build their success overnight? How many of them didn’t care about their goals? How many of them gave up after the first failure?
Most of the people we know to be successful were very persistent and devoted to their dreams. In other words, they work hard towards their dreams and keep trying, even if their goals aren’t easy to achieve. They didn’t give up just because they faced barriers and problems. They might even get encouraged by them.
Persistence really matters. It can help build your character. Nothing builds your character more than overcoming failures and problems in life. You get tougher and can handle anything life might throw at you. Each time you win your urge to give up, you make your mind and personality a bit stronger. Each of those wins will build your character to be healthier and to handle more stress.
When you are committed to something, you are willing to learn what it takes to be successful. You will be required to learn new skills and solve new kinds of problems. When you are persistent about your goals, you will have to learn new ways of doing things. Sometimes you might notice that to solve a particular problem, you need to learn more about it. When you study more about the topic, you discover new exciting subtopics to know about. As you think more in-depth into that problem, you will be exposed to new ideas and thoughts. Persistence is the driver behind your ability to learn what you need to know.
When you keep building your persistence and willpower, you will face many failures. Things don’t always end up as you have planned. With persistence, you will learn how to solve those problems and get back up after a failure. You will learn that failure is not the end of the world. Life goes on, and so can you. Each time you decide to overcome your failure, you will learn something new, and you will be a bit stronger than before. Those changes won’t show daily, but slowly they will start to stack up. If you look back and analyze your process, you will discover that you handle the stressful situation more efficiently, and after failures, you won’t go into despair. You rather know how to handle each failure as you have accumulated experiences from them and handle challenging situations.
Persistence is a basic quality to develop in life because it is closely related to personal development and improvement. As you already know, it is not easy, but it is worthy of your effort.
