What conditions contribute to common cold?
Below are several opinions that make sense to me.
It’s a mix of factors. Cold viruses thrive in cold weather. Cold weather and moving from heated environments to the outside causes drying of mucus membranes, mucus membranes are a first line defense, this usually causes itchy nose and the tendency to “pick” the nose or rub the eyes, introducing more viruses and bacteria.
The common cold virus will not survive in normal body temperatures. So if your body has the cold virus and you are exposed to cold weather, the virus can multiply. Breathing cold air can help the virus to reproduce if it is there. So try to keep your nose warm.
I would also think that if you were outside a lot in the cold, your body would be spending a lot of energy keeping warm, which would probably lower you immune system’s functioning by a bit.
During the flu season of 2005, an experiment was performed to test the idea that being cold can make you sick. 90 people kept their feet in a bowl of ice water for 20 minutes, while a control group of 90 people put their feet in an
empty bowl for 20 minutes. Over the next 5 days, 29% of the group with chilled feet developed cold symptoms, compared to only 9% of the control group.
Professor Eccles explained this effect by saying that our bodies restrict blood flow to the extremities when we get cold to help conserve body heat for the torso and brain, which really need to be warm. Cutting off the blood flow reduces the supply of white blood cells which are the immune system’s primary weapon against germs.
Food. While his explanation makes sense, there may be a more general effect at work. The human body is a machine that accepts fuel in the form of food, and uses that fuel’s energy to keep us warm and to power our immune systems, muscles and brains. However, in frigid conditions our bodies have probably evolved to say “who cares if I might get sick a week later when I’m going to die of hypothermia in half an hour?”
Most immune system stimulants contain vitamin C
. During an infection, vitamin C
levels in the bloodstream decrease dramatically. Vitamins A, E and the mineral zinc are also necessary for proper immune system function.
Other nutrients, such as calcium and magnesium are needed so that the cells of the body can easily absorb vitamin C. In other words, a good daily multi-vitamin, in addition to a well balanced diet, rich in fruits, vegetables and whole grains can be good to fight a common cold and for overall good health.
Change of seasons. In the United States, most colds occur during fall and spring. The common cold starts some time in late August or early
September and incidents of cold remain high until March or April, after which they start to decline. Many scientists attribute the spread of common cold to the season as during fall and spring, people tend to spend more time indoors
and the chances of virus spreading from one person to the next increases.
Do as your mother told you and ware a hat in the winter time anyway. Covering your ears and head will at least make you more comfortable when the icy cold wind is whipping around. And you never know–holding in even a mere 7% of your body heat might just make you that much warmer.
Simple steps to follow
•Rapid temperature changes affect your immune system the most.
So dress warm in winter and don’t forget the hat.
•Don’t run your air conditioner too low in summer.
•Healthy life style is critical for strong immune system. Eat right and exercise.
•Don’t drink cold drinks in any season-period. Cold icy drinks kill your stomach.
If you get sick use home remedies.
Not ibuprofen. Chicken soup!
Do not take antibiotics as a common cold remedy. There are hundreds of sites offering great home remedies.
In the winter don’t forget to let the fresh air in-open windows each day for a few minutes.
