Environment, has to do with all of things where you live. From your home, your job, your neighborhood, your city, state, and region. Here's a definition from our trusty dictionary:
1: the circumstances, objects, or conditions by which one is surrounded
2 a: the complex of physical, chemical, and biotic factors (as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival
2 b: the aggregate of social and cultural conditions that influence the life of an individual or community
When you look at the dictionary definition, you see how complex environment is. So many things can come into play when trying to figure out what single part is the cause, in this case, of multiple sclerosis.
Trends have shown that people in temperate climates have a higher incidence of MS. The farther away from the equator you go, north or south, the number of people who develop multiple sclerosis goes up.
This most likely has something to do with the fact that there is less sun the farther away from the equator you get. When you live in an area that gets less sun, your body can't make enough of this essential hormone. (And yes, it's actually a hormone).
So you, therefore, have more of a chance of having a vitamin D deficiency. We learned from Cir's doctor that many of his patients with MS have significant vitamin D deficiencies. (A possible cause of MS? Maybe). And since your body needs vitamin D in order to work properly, you will probably need to take supplements, especially during the cooler months.
I just found out that the average amount of clear days in my city is 68 out of 365. No wonder people here are likely to be deficient. Researchers have found that there is a link between the amount of vitamin D in your body and whether or not you develop MS.
Northeast Ohio has one of the highest numbers of people with MS in the US. It is along the same longitudinal line as several European countries which also have a high number of people with multiple sclerosis. Something to definitely think about and take a long, serious, hard look at.
If anything, maybe including this supplement in your diet can slow the progression, reduce the severity of your symptoms, or at least reduce the number of relapses.
