Over the last few decades we have all been inundated with messages about how important it is to stay out of the sun. We understand precisely how real skin cancer is as well as the risks associated with it so we do everything we can think to do to keep it from happening to us. We buy the highest SPF sunscreens we could find and then slather on layers and layers of it. We put on gigantic hats. We put on long pants along with sleeves even during the hottest months of the year. We try to stick to the low light areas-some individuals have even taken to carrying parasols around with them to keep the sun from ever making contact with their skin. Now we're beginning to discover that sunlight can sometimes be quite helpful. Can you actually be helped by the sun?
There is a new study that shows people who let themselves get some exposure to direct natural light aren't as prone to come down with MS as folks that take steps to minimize sunlight contact on skin. At the onset, the study was more about Vitamin D and it's effects on Multiple Sclerosis. It didn't take long for them to realize that it is the Vitamin D our bodies produce after exposure to sunlight that is at the center of the issue.
We've known for a very long time that the sun's rays and Vitamin D can hinder the way the immune system contributes to MS. This study, however, deals chiefly with the effects of sunshine on the people who are just starting to experience the very earliest symptoms of the disease. The real objective is to see how sunlight and Vitamin D may affect the symptoms that are now known as "precursors" to the actual disease symptoms.
Sadly, at this time there aren't truly very many ways that actually prove whether or not the hypothesis of this study are true. The study would like to demonstrate whether or not exposure to the sunlight can actually prevent MS. Sadly, scientists have realized that the only way to prove this definitively is to monitor a person for his entire life. This is just about the only way to really assess the levels of Vitamin D that are already present in a person's blood before the precursors to MS start to become apparent. The way it stands today, and has stood (widely recognized) for decades is that people who live in warm and sunny climates and who get more exposure to direct natural light are less likely to develop MS than those who live in dark or cold climates and get very little exposure to the sun.
There is also the very important issue that spending too much time in the sunshine greatly increases a person's chances of developing skin cancer. So, in an attempt to stave off one condition, you could be causing yourself to produce a different one. Of course, if you catch skin cancer early enough you are much more likely to cure it. MS even now has no cure.
So what should you do: risk skin cancer or risk MS? Ask your doctor whether or not this is a good idea. Your health care provider can examine your current health status, your medical history and even your genetics to determine if you are even at risk for the disease in the first place. From here your doctor can make it easier to choose the best course of action.
