Does cold really cause cold? That's what the experts say

According to an article published by Healthline and reviewed by a nursing specialist, Deborah Witherspoon, cold is not what makes you sick, but germs because you should be in contact with flu viruses for colds.

The cold is innocent

People who really think that cold causes infectious diseases may not understand how germs affect the body. Although protection against extreme temperatures is important for other reasons, it is not a cause of the disease.

Research at George Washington University found that young people were more likely to believe that cold causes illness. This means that children may not understand the best way to prevent colds and flu.

Corneal viruses increase in the spring and fall, but influenza viruses perform better in the winter.

But what is the link between disease and cold and winter?

Although cold can not be the only cause, there is a link between cold and disease: cold air can contribute to illness.

For example, some viruses are likely to spread in cold weather, especially rhinovirus (cold), for example in the nose (33 to 35 ° C) compared to the base body temperature (33 to 37 degrees). C)

However, one study showed that the body could not resist the virus if the temperature in the nose and upper respiratory tract was reduced due to ambient cold.

Some studies confirm that the flu virus is most stable in cold, dry weather. However, other studies show that the disease also spreads in hot, humid climates. Other factors that may affect the immune response include sudden changes in temperature or the effect of dark cycles and light.

But the end result is that cold does not cause illness, although time or other factors can weaken your ability to fight the disease.

Dry air is a problem

Dry air associated with central heating increases the accessibility of cold and flu viruses to dry nasal passages. The internal dry air does not get sick, but it can play a role in allowing sneezing drops in the air to survive and thrive.

According to the National Institute of Health in Britain, dry air in winter allows the flu virus to survive and spread. Further research by the Institute indicates that the coating of the influenza virus becomes stiffer at near-freezing temperatures, making it more active, more flexible and easier to transport in winter.

Sheltering cold is necessary

It is likely that being outdoors in cold weather will inhibit the workability of mucus and nasal hair.

It is also possible that when you return to the interior of a room where windows are closed and where people move, they may be exposed to germs. As people return to college, to school, and work in the fall, viruses find the ideal conditions to switch from one host to another, even before the next day. it's cold.

Low body temperature is an emergency requiring immediate medical attention. This happens when your body loses a lot of heat. May result from exposure to extreme weather factors.

Exposure to cold can cause tremors, homelessness, young and old, and even a loss of consciousness. It is possible that you have a health problem after too much wind or rain, drowning in sweat or water, and when your body loses a lot of heat.
