Can sunlight Help You Prevent MS?

By Vanessa Summer


For the last few years we have talked about little else besides why it is important to stay away from sunlight. We've realized exactly how real a risk skin cancer can be and are doing every little thing we can think of to prevent it from happening. We wear many layers of the highest SPF sunscreens that we can buy. We place large old floppy hats on our heads. We don long pants and also sleeves even through the hottest months of the year. We tend to stick to the shade--some folks may even carry parasols and umbrellas just to make sure they have exactly no contact with the sun. Now we're discovering that the sun can sometimes be beneficial! Can you really be helped by the sunshine?

A new study has been completed and it indicates that people who allow some time in direct sunlight aren't as likely to get MS as the people who do everything they can to keep out of the sun. At the onset, the study was a lot more about Vitamin D and it's influences on Multiple Sclerosis. Eventually it became clear, however, that it was the Vitamin D our bodies generate as a response to exposure to the sun's rays that seems to be at the root 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 plays a part in MS. This study, on the other hand, focuses on the affects of sunlight on people who are experiencing the very earliest symptoms of the disease. The actual objective is to discover how sunlight and Vitamin D may affect the symptoms that are now known as "precursors" to the actual disease symptoms.

Unfortunately, there are not all that many approaches to truly quantify the study's theory. The objective of the study is to figure out if sunlight can actually prevent the disease. Sadly, the only real way to quantify if this is accurate is to monitor a person over his or her entire life. This is just about the only method to seriously measure the levels of Vitamin D that are already present in a person's blood before the precursors to MS start to become apparent. As it stands now, people with normal sun exposure seem to have fewer MS symptoms, particularly in the beginning, than those who live in darker and colder climates-but this was already widely known.

The fact that the risk of acquiring skin cancer increases proportionally to the amount of time you spend in direct sunlight (without protection) is also a problem. So, in an attempt to keep one particular disease from setting in, you'll probably be inadvertently causing another. Of course, when it gets caught in early stages, skin cancer is very treatable and can even be cured. This isn't true for MS.

So should you get more sunshine to avoid MS from setting in? Your medical doctor may help you find out whether or not this is an alternative for you. Your health care provider can look at your current health status, your health background and even your genetics to determine if you are even at risk for the disease in the first place. From here your doctor should be able to make it easier to decide the best course of action.
