There is an old saying in English, “Laughter is the best medicine”. Until recently, few people took the saying very seriously. Now however, doctors have begun to study laughter and the effects (作用) it has on the human body. They have found evidence(证据) that laughter really can improve people’s health.

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate(率) and the rate of breathing. It also works several groups of muscles(肌肉) in the face, the stomach and even the feet. If laughter exercises the body, it must be helpful.

Other tests have shown that laughter appears to make the effect of pain on the body less. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which could bear the pain for the longest time was the group which listened to a funny program. The reason why laughter can make pain less seems to be that it helps to produce endorphins (内啡肽) in the brain. These are natural chemicals which make both stress and pain less.

There is also some evidence to suggest that laughter helps the body’s immune(免疫) system that is the system which fights infection (感染). In an experiment, one group of students watched a funny video while another group served as the control group — in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells that is the cells which fight infection.

As a result of these discoveries, some doctors and psychiatrists (精神病学) in the United States now hold laughter clinics, in which they try to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce good effects similar to those caused by laughter.

According to a new survey. Students’ safety has become a big problem. Nearly 50% of students say they are worried about robbery (抢劫) on the way to and from school. Now in some big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.

Chen Haoyu, a teacher at Beijing No 25 Middle School gives young students advice on how to deal with danger:

If you are robbed

Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later.

If you are in a traffic accident.

If a car hits you,you should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. This is because you don't know how badly you are hurt.

If it is raining hard and there is lighting. (闪电)

Don’t stay in high places and stay away from trees.

When there is a fire.

Run away as fast as you can. Put wet things on your body and try to find an exit. Do not take the lift.

If someone is drowning(溺水)

If you can’t swim, don’t get into the water. Cry out for help.

Remember that danger is never as far away as you think. Take care of yourself at all times!
