On the one hand, you will find the common cold truth, about which many experts agree. Then there are such things that might be considered common cold facts from a few, but not others. These mostly concern the very best ways to stop cold, common theories about why some individuals are more vulnerable to colds than others, and also the best way to treat cold symptoms.
Here are a few of the approved common cold facts. Colds are caused by viruses, not by being overheated or chilled. Being outside in cold weather doesn’t increase the likelihood that someone will”catch a cold”. Indoors is the area where most people likely become infected with a virus that contributes to a cold. Common procedures to stop the spread of cold viruses, including hand washing and disinfecting public surfaces are rewarding. Some of the viruses can live for as long as three hours on surfaces and skin, but warm soap and water or disinfectants can kill them.
There’s a whole lot of scientific research concerning the best ways to prevent the amount of colds that a individual has per year. The issue is that for each study that suggests that something works, there’s another study or 2 that contradict these findings. For instance, while there are several clinical studies which support the use of vitamin C supplements to stop cold, frequent statements from major health organizations imply that there’s no “clear” evidence that vitamin C supplements are successful. This could be largely due to the fact that 25 percent of individuals that are infected with common cold viruses not develop symptoms.

The reason that some people develop symptoms and others don’t is debatable, but recent research suggests that immune system function is a variable. A study of asthma sufferers, who are more vulnerable to colds, showed they produce less anti-viral proteins than usual. Anti-viral proteins, produced by specialized blood cells, can stop a virus from having the ability to reproduce and can destroy viruses by attaching to them and causing holes in their walls. Some experts think that those men and women who have more colds might have a well-functioning immune system.
This study suggests that, in at least some cases, a poorly functioning immune system may result in frequent cold symptoms. When it comes to the best way to treat a cold, common opinions change. The thought that no treatment will permit a cold to”run its course” more quickly cannot be supported by scientific study, but attempting to select one of the numerous popular cold remedies could be perplexing.
Some research supports the use of zinc nasal sprays or gels to decrease the duration of cold symptoms. Other researchers feel that suggesting this kind of therapy is unethical, since it might result in a permanent reduction of the sense of smell. Zinc lozenges, on the other hand, are thought to be safer, but much less successful in reducing the duration of a cold. Common cold treatment may never be quite profitable. The common cold may always be “common”.
