why do we get the flu in the winter


Speaking of all that gross, dry heat, youвre also more likely to get sick simply because youвre spending more time inside. That means youвre physically close to other people more often, breathing the same circulated air. Offices and schools are particularly treacherous. One
that a pathogen placed on a single doorknob could essentially infiltrate an entire office building within a matter of hours. Surfaces in the break room were particularly vulnerable to the spread of viruses. In this case, the only offense is a good defense. Try to be mindful of what youвre touching and who else might have touched it, and practice good (or hand sanitizer use) between touching potentially germy surfaces and touching your face or food. Solution: Try to work from home when sick, use hand sanitizer after touching shared surfaces (especially in the work kitchen and bathroom), remind your kids to keep their hands (and boogers) to themselves Cold doesnвt make you sick, but it does make you more vulnerable to illness In addition to making it easier for the flu virus to circulate, cold, dry air leaves your mucus membranes in rough shape.


Thatвs why respiratory illness sees a general uptick in the winter: is supposed to coat your respiratory system to protect it from pathogens, and wintry air dries that beneficial snot right up. as weвre exposed to different kinds of pollens and dander. When your nose is running and your throat is all itchy, your mucus membranes are irritated and vulnerableвwhich makes it easier for an opportunistic virus to make itself at home. Persistent allergies can also lead to secondary bacterial infections in your throat or sinuses. Thereвs also some evidence that our immune systems might take a hit in winter, whether itвs due to the cold itself or the lack of sunlight. Solution: Get a humidifier, treat your diligently to keep your mucus membranes happy, maintain good health by getting plenty of exercise, sleep, sunlight, and nutritious food If youвre already sick, well, sorry. Why do we get more colds and coughs in autumn and winter? I seem to remember something about the condensation carrying germs around in little \’germ packets\’, but I\’m not sure if I didn\’t make that up myself.


The most likely explanation is that in summer people are more likely to be out and about. In winter we all get away from the cold weather into confined spaces with air heating system which recirculate the air from those who have the virus which causes the cold. One theory is the decrease in ultraviolet light during the winter due to shortened daylight. Viruses are very sensitive to UV light as it destroys their DNA; less UV in winter, more viruses. Though decreased ventilation effectively increases the amount of virus in the air, since viruses causing respiratory disease are passed in water vapour we cough and sneeze from the respiratory tract, it is easy to breathe in where is starts it life cycle again. Ideal conditions to produce billions of virus particles My partner\’s psychologist says that colds are a physical manifestation of a psychological problem. In years gone by, winter would be the time for people, who worked in tune with seasons and nature, to rest up having got in the crops in autumn.

That, together with decreased daylight hours would make winter a time for increased rest and longer sleep. Now that we force our bodies to work longer and longer hours against nature, colds are our bodies way of forcing us to rest. Since we can\’t take days off merely to stay in bed, our body makes us sick so we have an excuse to stay home and sleep. Could it be something to do with the reduction of sunlight causing a depression of the immune systems? I think most research suggests that cold viruses are transmited by hand to mucus membrane. You wipe your nose, shake someone\’s hand and then they rub their eyes and are infected. So any explanation that involves ventilation/heating systems or condensation is suspect. The most likely explanation is that winter sees larger groups of people gathered together in close proximity leading to much higher infection rates. I think so this happens just because of the air pressure in the air.
