The real reason flu occurs in fall and winter

A scientist who made an important discovery.

He found that the flu virus doesnt die off every year, its always there in our bodies lying dormant. He noted that land populations 30 degrees in the Northern and Southern Hemisphere experience the same flu outbreaks like clockwork each year.

He made an important discovery in that vitamin d levels in the body produced by solar radiation through the skin would plumment in the fall and winter months within most individuals in the populations as the daylight hours became shorter and overcast days more frequent.

He found that 20 minutes of sun on the open body would be the equivelent of 40 glasses of milk to acheive the same vitamin d levels.

He used population isolation methods in which there was no travel to remote island area populations where the flu would be transmitted to the remote islolated population. The isolated population would experience the same effect at the same time of year as the larger mainland populations. He studied flu outbreak patterns through history documents from the last 300 years. In the tropics the flu outbreak would occur during the longest cummulative overcast days or during the rainy season.

It was found that the flu was not transmitted by community to community or house to house or person to person as is now the common belief. Each isolated population would become sick at the same time and only certain individuals within the household would become sick.

It was found that solar radiation which converts to vitamin d in the skin is needed by the immune system to prevent viruses from releasing inflammatory cytokines into the lungs and the vitamin d also was critical in keeping macrophage activity high in destroying the foriegn cells preventing a free radical cascade.

Sources plz...From what I learned year and year again in school. The flu you get is a different one each time. Say I got the flu this week. I was out sick and then in time I got better thanks to my friendy drugs and orange juice intake. Now, my immune system has built up a blockade (i'll say this cuz I can't think of a better word right now) that all germ related infections that it has faced before can not pass. This is because the T-cells can "remember" the germ and knows what is needed to kill it.(this is why you only get chicken pocks once, also.) So this means I will not be able to get the same flu again. Now, lets say it was 1+ year(s) from now. I got the flu again around this time. This flu is a new germ. the germ has evolved somehow that causes it to not be related to the flu I had before. You may have the same symthoms but it still is not the same. You'r body will repeat the process before and stop the germ. There are many, many, MANY different versions of the flu.

The reason why we get the flu more in a certin time of year is because the cold wears down our system. When we become cold our bodys try to warm us up so our imprtant organs do not freeze. If you stay in the cold for so long, less and less blood to traveled to certin parts of the body, parts that are not as important (ie: hands and feet). If this stays like it for to long frost bite can set in. Anyways, because of this your body is also able to caugh varies infections. Flu just happens to be one of the easiest ones that can enter your body.
