why do we get a cold when we are exposed to a cold climate or eat something cold?

Answer 1

First things first... the common cold is a virus, and not the body's reaction to temperatures.

If your body is used to a certain climate and a certain place, then your immune system is adapted for the local conditions.

If you are exposed to a cold climate, the only way for this to happen is for you to go to another country. (As opposed to cold weather, which is a very different thing. Climate = weather patterns over the past 35 years in a given area, Weather = what happens when you look outside the window. Raining now? Sunny? and so on.)

If you do indeed mean this, then your immune system is suddenly dealing with pathogens and viruses it never encountered before, and thus the variants of the common cold in this country is different to the variants in your own country. It will take time before your immune system adapts.

if you mean cold weather, it's not true. I'm living in Africa where the average temperatures range between 30c and 45c, and people often have colds. It's the virus.

Do you mean a runny nose? It's not a cold. It often happens when you are up hiking in the mountains. The sinus glands clears up. Your only option is to be well wrapped up and bring plenty of tissues.

Answer 2

The long answer above is mostly right, but it doesn't take into account that stress on the body of any kind causes the immune system not to work as well. Your body, right this very minute, is probably host to any number of viruses that could give you a cold. There are probably even more during cold season. Your body temperature lowers, and your body has to bring the temperature up. A lower core temperature causes problems across the board, and needs to be taken care of quickly. To do so, your body commits more resources in terms of energy to do this. This means that other systems get the short end of the stick, energy-wise. One of these systems is your immune system. Given that the viruses that are normally resident in your body are easily dealt with by your immune system, when your immune system isn't functioning as well, they have a better chance of reproducing successfully, thereby giving you a cold.

Answer 3

The short answer is that we don't get a cold when we are exposed to a cold climate or eat something cold.

Answer 4

I think that cold is bad factor when body is only partly exposed and does not know how to regulate heat energy adequately. On this point we are more sensitive to cold when we are dressed too warm. Then our throttle gets lower temperature and blood veins stretch .locally not giving proper circulation. Inflammable may start on basis of normally not affecting us viruses in that case. Quick return to normal circulation may solve problem. It may be any thermal shock or just hot cup of tea. Similar process is observed when exposing not covered part of body to cold wind for long time. This way we get aches of neck.

Answer 5

That is probably a myth. We do indeed tend to get more colds in cold weather, but this is not because germs love cold weather - quite the reverse. It has more to do with the fact that we all stay indoors with the windows closed, and are therefore more likely to catch germs from other people which are floating around in the air.

Answer 6

1: A cold is cause by a virus
2: The immune system protects us from most of the viruses and bacteria in the environment.
3: The immune system is taxed more (has to work harder) when we are chilled from cold weather or getting wet.
4: If it is taxed beyond its limit, you can catch a cold - something slips through
5 Boost your immune system = fewer colds.

Answer 7

no this is not getting a cold if you are speaking medical
''a cold'' is a virus and it is there in cold and in worm climates too
now here are 32-40 celsius and i am having a ''cold'' for 1 week that my nose is finished

Answer 8

Being cold doesn't directly give you a cold. However cold viruses prefer cooler weather, and constantly keeping yourself warm in the cold reduces your energy levels, which makes you more susceptable to illness.

Answer 9

because the coldness chills your blood, so cold is running through your body.

Answer 10

Actually, if you eat anything, your body temperature drops. Your cells are busy with the food and they constrict, causing your internal temp to drop.....I think, its been awhile since I have been in a science class.
