Hi there,

Cold weather, directly and indirectly, can increase the chances of one
catching a cold of flu.

Cold and flu viruses spread more easily in winter, because people
spend more time indoors, because the virus can survive longer, and
because people have drier throats.

"Colds and flu are more common during the fall and winter months. In
the past, some people believed that cold weather, going outdoors with
wet hair, or not being dressed warmly caused these respiratory
illnesses. We now know that these illnesses are more likely to occur
during these seasons because more people are indoors. This increases
the chance of person-to-person spread of a cold or influenza virus."

"Cold, dry weather boosts the survival time of some cold viruses,
which increases the chance of spreading. And the cold weather dries
out the lining of your nasal passages, making you more susceptible to

"Cold weather doesn?t cause colds and flu - you can catch them at any
time of year - it?s just that we spend more of our time indoors, where
stuffy air creates the perfect environment for these airborne viruses
to spread."

"Viruses and people cause colds and flu. People being in close
proximity to other people, indoors, with windows shut tightly bring on
cold and flu epidemics. School children are exposed to common winter
illnesses because of the many children sharing classrooms, lunchrooms,
and restrooms. Because the school term coincides with colder weather,
many people mistakenly concluded that cold weather is the culprit."

"Most colds occur during the fall and winter when people tend to spend
more time indoors, making it easier for viruses to spread from person
to person. Colds are also more common in winter because viruses
survive better in the low humidity environment of Winter. In addition,
cold weather dries out the nasal passages, making the sinuses
vulnerable to viral infections."
