Final answer:
Multiple Sclerosis (MS) is more common in cooler climates, a fact that is true. It is especially prevalent in regions at higher latitudes, presumed to be influenced by environmental factors like sunlight exposure and Vitamin D production.
Step-by-step explanation:
Multiple Sclerosis (MS) usually occurs in cooler climates. This statement is true. MS is more common in countries at higher latitudes, which often have cooler climates compared to those along the equator. Regions with higher incidences of MS include Canada, Scandinavia, and the northern United States, all of which are characterized by cooler temperatures. It is hypothesized that various environmental factors, including Vitamin D production from sunlight exposure, play a role in this geographical disparity. Therefore, the prevalence of MS is not aligned with hotter climates but instead with cooler ones.
