For years now , we have heard our mothers and grandmothers warn about catching flu from being outside in the cold atmospheric condition , especially without a hat or jacket . How much truth is there in the common feeling that you could catch a common cold by being outside in the chilly weather condition ? What , then , about the Alaskans and people living in Siberia , who live year - long above the Arctic Circle and pass each day outside in the cold weather condition ? try by the same belief , then people be around the equator should not be getting any colds . Let us research the truth about whether or not you get the flu from being out in the cold .
Is There A Connection Between Cold Weather and the Flu?
For years and class , the myth has been going around that going out in the cold weather will make you macabre , catch a frigidness , or fare down with the flu . However , while we have all grown up hearing this myth being reinforced by our mothers and grandmothers , then why is it that the peak flu season fall during the wintertime ?
The fact is that no , the frigid weather does not make you sick . Flu or influenza is an infective disease and germs make you fall sick , not the cold weather . for catch the flu , you need to be infected with the flu virus , and for charm a coldness , you demand to come in contact with rhinoviruses.(1)(2 )
However , the reason it seems like you come down with the influenza during the winter season is that the grippe virus tends to peak in winter .
Nevertheless , the dusty weather is not the only reason why you lean to catch the flu . There is also a connection between get sick and feeling chill in the winters.(3)The intellect behind this is that cold air contributes to other conditions that make us more susceptible to falling sick .
Your Immune System and Viruses
The cold weather is in reality idealistic for many viruses to broadcast . For example , research has found that rhinovirus ( which causes the coarse cold ) can reduplicate better and quicker at cool temperatures , especially in term that are present in the nose ( temperature of 33 - 35o Anders Celsius ) as compared to the organic structure ’s core temperature , which ranges between 33 - 37o Celsius.(4 )
The cold weather condition negatively touch on the resistant system , making it challenging for the organic structure to fight against possible bacteria and viruses . Some of the reasons behind this may include :
Lower Levels Of Vitamin cholecalciferol In The Winters : During the winter time of year , most multitude do not get sufficient photo to vitamin D due to lower sun exposure . Research by the Feinstein Institute for Medical Research in New York find thatvitamin Dis responsible for maintain the resistant system.(5)Low vulnerability to vitamin D , thus , causes the immune system to stop functioning optimally .
Narrowing of the Blood Vessel : Breathing in teetotal and cold air travel leads to the narrowing of the stock vessels in theupper respiratory tract . This is live as vasoconstriction . The body does so in an attempt to conserve heat . However , this prevents white blood cell from go to the mucose tissue layer , making it unmanageable for the eubstance to crusade against the invading bacteria or virus .
stay Cooped Up Indoors : In the winter calendar month , hoi polloi prefer to remain indoors rather than venturing out in the frigidness . Viruses are more prone to spreading from person to someone when everyone is indoors and close to one another .
The Yale University School of Medicine carried out a study in 2015 that discovered that the cells of the immune system lead up a more potent antiviral defense when they are at lung temperature , rather of the temperature in our nasal cavity.(6)This intend that the consistence is not capable to effectively crusade the computer virus when the temperature in the nozzle and upper airways is lower than the lung temperature , due to the dusty environment of winter .
Further studies carried out by the University of Arizona bespeak that theinfluenzavirus is able to thrive in cool and dry temperatures . However , studies by the US Department of Health and Human Services has also demo that grippe is also far-flung in warm and humid climates.(7 )
This indicates that other factors are also at play when it comes to determining the immune response of a mortal to the influenza computer virus . These may include variety in temperature or even the encroachment of light and dark cycle .
Nevertheless , the bottom line still established by all these study is that dusty weather or spicy conditions does not cause the flu . Weather and other factor counteract your resistant organisation , diminish your power to fight off the grippe .
Other Factors That Cause Flu or Illness
As remark above , there are many other factors in the wintertime season that weaken your immune organisation , extend to diseases . Some of these factors are front at below .
Central Heating
Perhaps the most significant factor responsible for so many cold and the grippe in the winter season is central heat . When it is moth-eaten outside , you prefer to remain indoors , where the temperature is tender . fundamental heating and the dry air associated with key heating makes it very easy for the flu and cold viruses to enter your wry nasal bone passages .
Even though wry indoor air , by itself , is not going to make you fall sick , but it plays a meaning function in allow aerosol droplet from a sternutation to fly high and survive .
In 2011 , a research squad at China ’s Tianjin University came to the stopping point that students living in residence hall elbow room with poor indoor ventilation were catching more colds.(8)Similarly , another 2011 inquiry at Virginia Tech University encounter that right ventilation and high relative humidness indoors pull the influenza character A virus to become inactive.(9 )
Perils of Staying Outside in the Winter
The winter months lean to have dry melodic phrase . Dry winter air is associated with flu outbreaks . The National Institute of Health ( NIH ) tell that dry wintertime air aids the selection and transmitting of the grippe virus.(10)Research by the National Institutes of Health has found that the coating or outer tissue layer of the influenza virus becomes tougher when expose to temperature that are close to freeze . This makes the virus more active , more resilient , and it gets easily transmitted in the cold weather.(11 )
Prevention from the Cold and Flu
Here are some tips on how to avoid falling crazy with the grippe or catching a cold during the winter season :
Remember that influenza is one of the only respiratory virus that can be prevented byvaccination . This is why it is so essential that you get your yearly flu gibe .
5 Home Remedies To Get Rid of Flu or Cold
There ’s no discussion for the flu except to battle it out . Here are some tried and test dwelling house remedy that help you treat with the grippe and make you sense slightly well as you hold off out the virus :
Conclusion
stale weather condition does not cause the flu and the mutual cold . These unwellness are triggered by viruses such as influenza ( flu virus ) and rhinovirus ( cold computer virus ) . The weather condition , though , has a role in increasing a person ’s endangerment of catching a virus and fall down sick .
Research has shown that the flu and cold virus can thrive and breed rather rapidly when let out to cold temperatures , which makes it easier for them to spread and taint other masses . Staying indoors during the dusty conditions also increases the risk of more people getting taint with the virus . At the same sentence , inhuman atmospheric condition lowers the body ’s immune reception , making it unmanageable for the body to fight off these viruses and bacteria .
By taking right precaution and by following good hygiene , you will be able to protect yourself from the flu during the wintertime months .
