If the cause of catching cold is a virus, so why we catch cold in a cold weather?

Question

Is there any relations between this virus and cold weather?

Answer 1

I think the cold virus is beeing spred during the cold season,so they can sell medications and stuff.

Answer 2

There could be many reasons. My granddaughter is constantly bringing colds home from school. Since she mainly goes to school in the winter there could be a connection there. Also, exposure to cold air could compromise your immune system making you more susceptible to getting a cold.
You are in closer quarters in the winter because you want to stay warm. This might increase exposure to people who have colds themselves.
Colds are caused by a virus but there are many different viruses that cause a cold. Once you catch a cold you are immune to that particular virus but you could catch a cold from another stain. Except for possible mutations, there is a limited number of viruses that cause colds. This is why you tend to catch fewer colds as you get older.

Answer 3

There a two primary viruses that cause colds. The Rhino virus, genus of the Picornaviridae family of viruses causes about half of all colds.

Rhinoviruses have two main modes of transmission: In the past it was obvious that these viruses were transmitted directly from person-to-person via aerosols of respiratory droplets. However, now they are known to be transmitted indirectly via respiratory droplets that are deposited on the hands and then transported by fingers to the nose or eyes.

These droplets left on surfaces last longer in cold and humid environments. Also, in cold weather people spend more time in doors and exchange the air less often and this exposes the virus to more people for longer periods of time.

The coronavirus accounts for most of the rest of the colds. SARS which killed many people in China is from the Corona genus.

Answer 4

Normally, your immune system is exposed and your body fights off the infection. You stay healthy. If you have already been exposed to the virus and currently have it in your system, getting chilled may reduce your immune system allowing the virus to expand its hold and eventually take its toll. That is why it 'appears' that you get it from going outside and getting cold. Please note that getting 'chilled' is different from being in cold weather. Most people in cold weather don't get chilled unless they are wet. So, your Mom is right, but not for the reasons she believes. Also, summer colds are caught in pretty much the same way. Someone has a virus and passes it onto you. I agree with the poster above for everything except her final paragraph.

Answer 5

In cold weather people stay indoors more and are around more people in a smaller space. You body has to fight off the cold temperatures and that lowers your immune system and that makes it easier to get the virus.

Answer 6

The change in tempertature has been studied extensively, but no single medical book talks frankley about cold and its relation to Upper Respiratory Tract infections. Some say that viruses become active by changing temp, and others relate it to immune system becoming weaker.

Answer 7

Cold weather don't give you cold. More people spend time indoors and are sharing the same air. Since windows and such are genarlly colsed in winter fresh air is not comming in. Wash hands good and drink lots of liquids.

Answer 8

the cold weather lowers the effectiveness of your immune system and therefore makes you more susceptible to the virus.

Answer 9

viruses live in hot and cold weather just fine. and we catch cold in cold weather cos our body wastes all strength on keeping us warm, so immune system gets weaker

Answer 10

I'm getting over a cold right now.
