Environment, has to do with all of things where you live. 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

Merriam-Webster Dictionary

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, the number of people who get multiple sclerosis goes up.

This could have something to do with the fact that there is less sun the farther away from the equator you get. When you live in area that gets less sun, your body can't make enough.

So you, therefore, have more of a chance of having a vitamin D deficiency. And since your body needs vitamin D in order to work properly, you will probably need to take supplements.

Can you believe it?


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.
