“冬伤于寒，春必温病”什么意思，为什么？

经谓“冬伤于寒，春必病温，”是训人有伏气之为病也。夫冬伤于寒，甚者即病，则为伤寒，微者不即病，其气伏藏于肌肤，或伏藏于少阴，至春阳气开泄，忽因外邪乘之，触动伏气乃发，又不因外邪而触发者，偶亦有之。其藏肌肤者，都是冬令劳苦动作汗出之人；其藏少阴者，都是冬不藏精肾脏内亏之辈。此即古人所谓最虚之处，便是容邪之处。何刘松峰、陈平伯诸公，皆谓并无伏气，悖经之罪，其何逭乎！据丰论春时之伏气有五∶曰春温也，风温也，温病也，温毒也，晚发也。盖春温者，由于冬受微寒，至春感寒而触发。风温者，亦由冬受微寒，至春感风而触发。温病者，亦由冬受微寒，寒酿为热，至来春阳气弛张之候，不因风寒触动，伏气自内而发。温毒者，由于冬受乖戾之气，至春夏之交，更感温热，伏毒自内而发。晚发者，又由冬受微寒，当时未发，发于清明之后，较诸温病晚发一节也。此五者，皆由冬伤于寒，伏而不发，发于来春而成诸温病者，当辨别而分治之。

这是清代医家雷丰《时病论》的观点。不过近代名家蒲辅周老先生对《内经》这段内容颇不以为然。希望读者理智地、辨证的看待这个问题。

Many people catch a cold in the springtime or fall.It makes us

wonder… if scientists can send a man to the moon,why can't they find a

cure for the common cold?The answer is easy.There are actually hundreds

of kinds of cold viruses out there.You never know which one you will

get,so there isn't a cure for each one.

When a virus attacks your

body,your body works hard to get rid of it.Blood rushes to your nose and

cause a block in it.You feel terrible because you can't breathe

well,but your body is actually eating the virus.Your temperature goes up

and you get a fever,but the heat of your body is killing the virus.You

also have a runny nose to stop the virus from getting into your

cells.You may feel miserable,but actually your wonderful body is doing

every- thing it can to kill the cold.

Different people have different

cures for Colds.In the United States and some other countries,for

example,people might eat chicken soup to make themselves" feel

better.Some people take hot baths and drink warm liquids (流汁).Other

people take medicine to stop Various symptoms (症状) of colds.

There is

one interesting thing to note" some scientists say taking medicines

when you have a cold is actually bad for you.The virus stays in you

longer because your body doesn't have a way to fight it and kill

it.Bodies can do an amazing job on their own.There is a joke,however,on

taking medicine when you have a cold.It goes like this:

It takes

about one week to get over a cold if you don't take medicine,but it

takes only seven days to et over a cold if you take medicine.
