A study conducted by the University of Leeds in the United Kingdom suggest that watching cute animals may lead to a reduction in stress and anxiety.

The study examined how watching images and videos of cute animals for 30 minutes affects blood pressure, heart rate(心率) and anxiety. In December 2019, 19 people, including 15 students, joined in the study.

"There were some kittens, there was puppies, there were baby gorillas, there were quokkas —cute creatures found in Western Australia, are often referred to as 'the world's most cheerful animals'." Dr. Andrea Utley, a professor at the University of Leeds told CNN. The study was timed during winter exams, a time when stress is at an especially high level for students, according to Utley.

 The study recorded that the average blood pressure dropped from 136/88 to 115/71, which the study pointed out is "within ideal blood pressure range." Average(平均的) heart rates were lowered to 67.4 bpm, a reduction of 6.5%. Anxiety rates also went down by 35%.

"I was quite pleasantly surprised that during the session, every single measure for every single participant dropped some — heart rate reduced, blood pressure reduced," Utley said. "When they left, they filled the questionnaire(调查问卷) in again and showed that they were feeling less worried."

When questioning the participants, the study found that most preferred video clips over still images, particularly of animals interacting with humans.

What would you do if you see someone hurt badly? The following will help you to learn some important skills to give casualty (伤员) first aid.

{#blank#}1{#/blank#}

The first and most important thing you must do is to make sure the place is not dangerous. Can you see anything that might not be helpful to you? Can you hear anything that could be dangerous?

{#blank#}2{#/blank#}

When you see someone has been hurt, you may feel scared. If you feel yourself starting to be nervous, try to calm yourself down. For example, talk to people you trust about what happened, and you'll be relaxed.

{#blank#}3{#/blank#}

When someone needs first aid, talking to him will help him to stay calm and feel safe. Even if he does not answer you, you should still tell him what you are doing. It will let him know that you are helping him.

{#blank#}4{#/blank#}

Sometimes, the casualty will need more help than you are able to give. The best thing you can do is to phone some people for help. They can give you some useful advice or offer you some help.

{#blank#}5{#/blank#}

There are also many other things to do. Try your best to help the casualty. Asking people around you for help is really better than waiting for doctors. Besides, you can also try to keep in touch with his families and friends.

Many people take running as a way to keep fit. They like to run in hot weather and enjoy the feeling of being wet through with sweat (汗) while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep people from running in the open air.

However, a new study shows that the drop in temperature is a good reason to run. In fact, running in cold weather helps improve one's performance. Many runners might find it easier to run in winter than in hot weather. The body needs less water on a cold day than in warm weather. In addition, lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower.

John Brewer is a professor of applied sports science at St. Mary's University in London. For this study, he and other researchers put a group of people into a room where summer and winter weather conditions are recreated. The test subjects were asked to run 10,000 meters under both conditions and their biological measurements were recorded and studied.From the study, every movement runners make produces heat. The heat can be really damaging unless the body can lose it. One way in which people lose heat is by sweating. The body loses heat through sweat. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, especially in hot conditions because it's much harder to lose heat when the outside environment is warm. As the result shows, running in hot temperatures results in 6 percent higher heat rates.

When running in cold conditions, the body does not have to work hard to move blood to the skin surface. Therefore, it requires less energy. The most important thing for people who run in cold conditions is to wear the right clothing. Keep as dry as possible when exercising in low temperatures. Wear warm and light clothing to keep sweat away from your skin. So don't let winter weather keep you indoors. Simply get ready for the low temperatures and start running.

There are 24 solar terms(节气)in China. They can guide farming activities and are believed to be an outstanding achievement by ancient Chinese. 

Grain Rain" is the sixth solar term in the 24 solar terms and it is the last solar term in spring. It falls on April 20 this year. The term"Grain Rain" came from a folk story. When Cang Jie created writing characters, grain came down from sky like rainfall. Therefore, the Yellow Emperor named this day as the "Grain Rain". When this day comes, the number of rainfall increases. It is very important for the growth of the grain. 

Nowadays, different areas have different customs during "Grain Rain", Picking and cooking tea leaves: "Grain Rain Tea" is the name for the tea made around the time of "Grain Rain" in the south of China. it is considered as one of the best kinds of tea. it not only has a strong and good taste but also can last for a long time in water. 

Blessing(祈福)to the sea: "Grain Rain" is a perfect time for fishing. Since it gets warmer and warmer, the sea also gets warmer and more fishes swim in the sea. Fishermen in the north often bless for safety and success on the sea. 

Killing insects: As the weather gets warmer. insects become more active. Farmers in Shandong, Shanxi and Shaanxi often use different methods to kill insects. 

Taking a bath: In some of the north-west areas, people take the shower in the river during "Grain Rain" period. They think it can help them be far away from the bad luck.
