Does the cold cause the disease?
"If you don't wake up, you catch your death cold." Many of us have heard similar words about the connection between the cold and catching the disease. Although most of us believe that the cold does not cause disease, the jury is officially still out. Most research supports that colds do not affect someone's probability of catching a virus that causes a common cold or flu.
Medical research in the 1950s exposed 400 volunteers to cold viruses using different temperatures and conditions as variables. The result was not the difference in the level of infection between different groups. A similar study at the end of the sixties brought comparable results.
However, some studies indicate that there is a cold of illness. Some arguments suggest that if you are cold, your body is more stressed and therefore less resistant to the virus. Research by Common Cold Center in Wales has shown that a decrease in body temperature can cause a dormant colvirus to develop. If a person cools down, for example by carrying damp clothes inCold weather, blood vessels in the nose are narrowed. When this happens, warm blood is closed, it no longer provides white cells fighting infection.
One study included the effects of volunteers who placed their bare feet in an empty bowl for 20 minutes or soaking the legs in a bowl containing ice cold water for the same time. Within five days after the experiment, more participants who soaked their feet in cold water have evolved cold symptoms than other participants. According to the study, several of these participants were most likely to have been cold, but it has not yet shown symptoms. Reducing body temperature was a contributing factor; In this case, the cold caused disease, not a virus, but a virus development.
More likely, the fact that people tend to illness more often in the winter season is increased internal contact with others, some of which have viruses. Given that pOwn is cold, people tend to remain in the interior more often and create places such as schools, shops, airports and offices, which are likely to be captured.
people usually catch colds over air droplets from sneezing. Other methods of catching colds are contact from hand to nose or eye areas after direct contact with a person who has a virus or indirect contact, such as touching with the same click.
The best way to avoid colds or virus, it is not to avoid cold, but instead avoid crowded places and often wash your hands. And the results of another study suggest that those who have positive views and are positive is less likely to catch colds than those who had a more negative emotional style.
