　　每年一到新学期，总能听到学生在军训中或开学典礼上晕倒的消息。据楚天金报9月1日报道，某校开学典礼只有半个小时，竟有15名初中生相继晕倒，坐在一旁的家长一脸无奈。该校负责人也直摇头，都是温室里的花朵，平时锻炼得太少了啊！

Every year to the new semester,Can always hear students in military training or opening ceremony on the news of the faint.According to the chutian 27 September 1st,School opening ceremony only half an hour,Have the 15 junior high school students have faint,Sitting on a side parents a face of helpless.The school chief also straight shook his head,Are the flowers in the greenhouse,Usually exercise too little ah!

暑期习惯惹的祸 Summer habit to blame

　　“各地学生晕倒与暑假生活习惯有直接关系，家长病态的教养方式也是祸根。”中国教育科学研究院体育卫生与艺术研究中心主任吴键接受记者采访时说，暑假里家长关心的依然是孩子的学习，孩子们除了做作业就是上补习班，一旦孩子学习累了，家长通常让他们看电视或者睡觉，缺少应有的户外活动和体育锻炼，这种病态的教养方式很令人担忧。

"Students all across faint and summer are directly related to the living habits,Parents pathological education mode is an apple of discord."China's education scientific research institute sports health and art research center director WuJian told reporters,During the summer vacation parents care about is still the child's learning,The children in addition to do my homework is to go to cram school,Once the children learn tired,Parents are usually let them watch TV or go to bed,The lack of due outdoor activities and physical exercise,This kind of morbid upbringing very worrying.

　　学生不健康的生活习惯也是原因之一。“暑假里许多孩子长时间待在有空调的室内，不去户外锻炼身体，导致身体的温度调节能力被破坏。”他举例说，自己有个亲戚是初二学生，暑假里每天坐爸爸的车穿梭于各种培训班，成天都在空调车和空调房里度过，一个假期几乎没有见到阳光，结果身子发虚，头晕、发热、盗汗，医生诊断是得了“空调病”。

Students' unhealthy habits is also one of the reasons."In summer many children long time to stay in an air-conditioned indoor,Don't go to outdoor exercise,To cause the body temperature adjustment ability be destroyed."He said one example,You have a relative is 2 students,In the summer vacation every day sit dad's car shuttle in various types of training,All day in the air conditioning unit and spend,A holiday almost did not see the sun,Results the body breezing,dizziness/fever/Night sweats,The doctor diagnosed is got"KongDiaoBing".

　　吴键强调，人处在温度变化的环境时，身体能自动调节。太热时，出汗就是典型的散热办法；太冷时，打个寒战、活动活动身体，就可以让身体产生热能。但是，这种温度调节的能力，只有在冷、热变化的环境中才能获得，在恒温的空调环境里则得不到锻炼和提高。

WuJian emphasize,People in the temperature change of the environment,The body can automatic adjustment.Too hot,Sweat is the typical cooling way;Too cold,A chill/Exercise the body,Can make the body produces energy.but,This kind of temperature regulation ability,Only in the cold/Heat change environment to achieve,In the constant temperature air conditioning environment can't get exercise and improve.

血压调节能力差 Blood pressure regulation ability is poor

　　吴键手中拿着的一份研究成果表明，大部分学生晕倒是暂时性脑部供血不足所致，根本原因是学生的血压调节能力差。还有部分学生是体温调节能力差，不能忍受阳光直射，就是俗话说的“热晕了”，“有些平时身体锻炼较多的孩子，也会晕倒。”

WuJian hands holding a research results show that,The majority of students faint is temporary brain caused by loss of blood supply,Root cause is the student of blood pressure control ability is poor.There are still some students are thermoregulation ability is poor,Can't stand the sun,Is the old saying"Thermal blooming the","Some usual exercise more children,Will faint."

　　他打了一个比方，血压调节能力强的人，姿势突然改变或较长时间保持不变时，会通过血压的自动调节，保证身体各个部分的血液供应。而血压调节能力差的人，较长时间保持直立状态时，血液不能及时将氧气等物质输送到大脑，就会造成大脑缺血。研究证实，由于部分青少年平时缺乏运动锻炼，做作业、看电视、上网等静坐时间过长，血压调节能力得不到锻炼，久而久之机能下降，因此，难以保持长时间静止站立，甚至出现晕倒现象就不难理解了。

He gave a example,Blood pressure adjustment ability strong people,Posture suddenly change or a long time when remain unchanged,Will through the automatic adjustment of the blood pressure,Ensure that different parts of the body's blood supply.And blood pressure adjustment ability difference person,A long time to stay upright condition,The blood can't timely will oxygen and other material conveying to the brain,Will cause the brain ischemia.Study confirms,Due to some youngsters usually lack of exercise,Doing his homework/Watching TV/The Internet and sit for a long time,Blood pressure regulation can not get exercise,As time passes function drops,therefore,Difficult to keep for a long time to stand still,Appear even faint phenomenon is easy to understand.

　　据广东医学院生理教研室副教授蔡波介绍，高温环境下，皮肤血管容易舒张，容纳的血量随之增多，增加了人体发生昏厥的可能性。如果孩子长时间坐在空调房里，一旦站立，很容易发生昏厥。

According to guangdong medical college physical teaching and research section, an associate professor at CaiBo is introduced,Under the environment of high temperature,The skin blood vessels easy to relaxation,Hold the blood volume increases,Increased the human body in asphyxial possibility.If the children long hours in air conditioning room,Once stood,Very easy occurrence fainting.
