Cold weather during winter months may keep many people from leaving home and running in the open air.

However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one’s performance.

Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body’s dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

This information comes from sports scientists at St. Mary’s University in London. John Brewer is a professor of applied sport science at St. Mary’s.

For this study, he and other researchers put a group of people into a room they called an “environmental chamber.” The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

“We’ve got a group of subjects into the environmental chamber, we’ve changed the conditions to replicate the summer or winter and we’ve got them to run a 10km under both of those conditions and taken various measurements on each runner while they’ve been completing their 10km.”

Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

1.What can we know about running in winter?

A. It increases pressure of the body.　　 B. It improves the function of body.

C. It makes your heart rate higher.　　 D. It needs more water than in summer.

2.What can we know about the research according to the text?

Cold weather is good for you

With winter approaching, people begin to complain about cold weather. 1. There’ s plenty to love about cold weather. And there’ s plenty of evidence that cooler temperatures can be part of a healthy life.

First, cooler temperatures can help you lose weight. It can also help you sleep better. You might feel uncomfortable at first if you cool your bedroom down. But if you, for example, switch your bedroom temperature from 72 down to 62 degrees gradually over a few weeks, your body will adjust. 2.

I have long kept my winter house temperature at 62 degrees. How did I find that number? Well, I experimented on myself about eight years ago. 3. I started at 66 and turned it down one degree every few days until 60. I found when the temperature was colder than 62, I couldn’t focus. But 62 was perfect. Another benefit for me was that it also kept me clear-headed while working at home.

Interestingly, science also says 62 degrees is the magic number for brainwork. 4. It said 62 degrees was the temperature at which the schoolboy subjects of the study functioned perfect. And while we’ re speaking of work and school, other research shows that people study better when the weather outside is “bad”.

5. But according to a Harvard Health Letter from 2010, proper cold temperatures could be good for skin because it trains blood vessels in the skin to be responsive. So, rosy cheeks ! There’ s no reason to be afraid of winter weather. Hug it and you, too, can enjoy the season.

A. I recently read a 1972 study.

B. And you’ll save money on energy costs as well.

C. Many people like to use cold water to wash their face.

D. At that time, I worked at home and liked warm temperature.

E. Most of us think cold weather leads to dry skin and wrinkling.

F. The reason was that I hated spending money on heating bills.

G. But if you’ re active and healthy, it doesn’t have to be a negative thing.

Clothes can make phone calls, play music, dial your pal’s number, keep you warm during cold weather and operate your computer?

This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes — clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended(混合) with flexible electronic materials to create intelligent clothing. The result are electronic garments.

If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say.

The Electrotextiles team has also created the world’s first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These ‘lap- tap’ gadgets(器具) are all set to take over laptop computers!

Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(风帽) and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?

1.. The electronic garments are similar to other electronic devices in that ______.

2.. How will researchers improve these high-tech clothes?

3. What does the underlined phrase “This handy invention” in Paragraph 5 refer to?

4.. If you are going on a ski adventure, which device do you need?

5.. The main purpose of the text is ______.

How to Fight Winter Blue

Winter’s short days are more than cold. For many people, winter depression, the most common type of Seasonal Affective Disorder (SAD), is as much a part of the season as hats and scarves.

Winter serious SAD sufferers may need medical treatment. Those feeling a little blue can help themselves by sticking to a healthy lifestyle.

Here are some tips:

Pace yourself. Don’t expect to do everything you normally can. Set a realistic schedule. Don’t listen to negative thinking, like blaming yourself or expecting to fail.

Get involved in activities that make you feel good or feel like you’ve achieved something. For example, play table tennis or badminton.

If you are feeling depressed, you may feel like staying away from friends. Yet this is a time when friends’ support can be helpful. Call them regularly. Remember, the more we put off calling or visiting a friend, the harder it is to rebuild a friendship.

Think clearly about what’s wrong or right. Instead of giving in to vague feelings of sadness, look at your problems objectively. Break down problems into specific issues that you can work on.

Regular exercise helps to prevent and ease depression.

Eat well. Studies show that a healthy diet can help to maintain (keep) a healthy body and mind. The vitamins, minerals and micro—nutrients found in balanced diet may help our bodies to produce feel-good hormones(荷尔蒙). Foods containing chemicals to help produce feel-good hormones include bananas, turkey, nuts and seeds. Eat at least five pieces of fruit and vegetables every day.

P.S.  Symptoms(症状) of SAD:

No interest or pleasure in things you used to enjoy.
