Researchers believe the reasons may be both objective — as in happiness improving immune function — and subjective — as in happy people being less troubled by a sore throat or runny nose. "People with a positive emotional style may have different immune responses to the virus," explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe."
Cohen and his colleagues had found in a previous study that happier people seemed less likely to catch a cold, but some questions remained as to whether the emotional style itself had the effect.
For the new study, the researchers had 193 healthy adults complete standard measures of personality characteristics, self-felt health and emotional style. Those who had a tendency to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and aggressive had a negative style.
The researchers gave them nasal (鼻腔的) drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains or sneezing they had, while the researchers collected objective data. Cohen and his colleagues found that based on objective measures of nasal troubles, happy people were less likely to develop a cold.

During the school year many parents take on the role of driver as they drive their children from one lesson to another. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie, it's their school work that suffers the most. "After school, if they're busy in a number of sporting events, besides, they need to do their homework, then the time they'll feel sleepy is in the classroom. Your child needs free time. So if you're filling up that after school time, then it's during the day that they're going to be taking a break. "
Professor Claire McDermott agrees that there's a lot to be gained from sometimes putting those scheduled lessons and activities away. "Relaxing time is important for children. It's time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn't look like productive time; parents certainly wouldn't be saying ‘Wow, are they ever learning things now?’ But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, and it also helps to understand the learning that's gone on that day. "
It's hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. "When we get our children in too many activities because we want our children to experience everything, then what we're doing is setting them up not to be good at one thing or gaining a skill." So choose your children's activities wisely. It may be one of the best things you've ever done for your kids.
60. What is the biggest disadvantage for children to attend too many lessons after school?
A. They can get bored easily about everything.
B. They might have no time to do the homework.
C. They might not pay much attention to learning.
D. They can not easily focus on learning during the day.
