Never an Easy Season with MS

By: Matt Cavallo

I was really excited. My allergies were horrible and I was feeling absolutely miserable. Why does this excite me you ask? When I feel horrible, I get inspired to write and was going to write a piece on allergies and MS as a follow-up to last year’s, Is There a Relationship between MS, Allergies and Histamine blog.

Then, this happened to my local weather in Arizona:

Out here in Arizona, we say that three straight days over 100 degrees kills all the pollen. I don’t know if this is true or not, but my allergies certainly haven’t been bothering me since it got into the 100’s at about Friday of last week.

But guess what? The heat has been killing me!

Luckily, I got a Kool-Max cooling vest, similar to those in the MSAA’s Cooling Program. Now, even in the dog-days of summer, I can still participate in activities or chores and not feel trapped inside by the summer heat.

This got me to thinking, is there ever a perfect season to have MS? We all know that the summer heat, no matter where you live, is not good for MS. The symptoms of heat exposure can cause a pseudoexacerbation, or brief episode of neurological symptoms not classified as a relapse. These pseudoexacerbations can come and go all summer long as the heat and humidity persist.

However, during the cold dark of winter, us MSers yearn for a hot summer day. The low light of winter is not generally considered good for people with a Vitamin D deficiency, as most of us living with MS may experience. Winter also presents trip hazards with ice and snowy conditions, so those of us more prone to falls have a harder time getting outdoors and staying active during the winter.

Fall presents many of the same trip hazards. As soon as the leaves turn colors, they drop to the ground and become slippery to walk on. Fall also has dramatic temperature fluctuations where it can be summer hot one day and then brutally cold the next. This is where cold and flu season start to come into play along with the pseudoexacerbation possibility from those really gorgeous summer-like fall days.

That leaves spring as the only possibility for an easy season living with MS, am I right? Wrong. Spring is the reason I started writing this blog. It was nice this year, but the pollen kept me from enjoying it. I could not differentiate from an MS day or a sick-with-allergy day. The inability to breathe really caused excess fatigue rendering me unable to discern the difference between allergies and MS symptoms.

The truth is there is no easy season when you live with multiple sclerosis. However, each day is what you make of it. Don’t let the changing seasons stop you from living your life, rather adapt with the seasons and plan accordingly. Wear sunscreen, stay cool and don’t let MS stop you from having the best summer ever!

What is a Pseudoexacerbation?

For many individuals with MS, the summer can be a difficult time. The heat and humidity may cause MS symptoms to flare and become agitated because of heat affecting one’s body temperature. For some who experience a worsening of symptoms in warm environments, this may actually be an example of a pseudoexacerbation. A pseudoexacerbation is a temporary worsening of MS symptoms, without the presence of actual myelin damage or inflammation. Other than heat, individuals may experience this as a result of other illnesses or infection. It is important to take note and be aware of what symptoms you are experiencing, how long they occur, and your environment surroundings. If you find yourself heat-sensitive, try to avoid warmer settings. Stay in air conditioned places, do outdoor activities either early in the day or after sunset when the temperature is cooler, and wear lighter weight clothing when needed. If you have concerns about or are experiencing new symptoms it is important to be aware of your activity and surroundings, especially during these warm summer months!
