Long ago, a MS heat intolerance test was performed on people suspected of having MS. Multiple Sclerosis heat intolerance was tested with a hot bath. When the patient was submerged into a bath of hot water, neurologic symptoms were observed. If the symptoms became exacerbated, then the patient was suspected of having MS. Once MRIs became available, the ‘hot bath’ test was no longer necessary.
Due to the build-up of plaque on nerve cells where the immune system has stripped the myelin sheath off, the nerve functions are slowed down. Heat actually slows down already sluggish functions even more so. For some MS patients, the rise in temperature can be as small as a quarter of a degree to aggravate symptoms.
Symptoms of Multiple Sclerosis heat sensitivity include blurred vision, tremors, fatigue, memory problems, numbness, an overall weakness, and difficulty with cognitive function. Some patients are more sensitive to a rise in temperature than others. For instance, one person with MS might be able to take a walk outdoors in 95 degree weather and not be affected, as long as the sun is avoided and cool drinks are consumed. As for symptoms, they are generally the same between patients, but differ in severity. One person might find the symptoms to be rather annoying and another could be in utter agony. There is also a variation between the amounts of time needed to lower the body temperature to alleviate any discomfort from MS symptoms.
Creating MS Heat Tolerance
MS patients are able to manage their sensitivity to heat through a number of methods. Consuming plenty of fluids is always helpful, especially cool liquids. Being properly hydrated allows the body to perspire and attempt to maintain a comfortable body temperature. Sucking on frozen juice pops or chipped ice is another way to lower internal body temp. Of course staying indoors where air conditioning is present is an easy way to prevent overheating.
Cool showers, swimming in an unheated pool, or using cooling products will all lower the body temperature rather quickly. Cooling products include vests with pockets for ice packs, battery operated vests to reduce the absorption of heat from the surrounding area, and scarves, hats, or wristbands with cooling gel encased in the lining.
MS heat intolerance can be deadly if not taken into consideration. Reports of deaths occurring from intolerance to heat in MS patients have been noted. These individuals were enjoying time in a hot tub or basking in the sun when they became unable to get out of the heat, due to physical changes that occurred within their bodies. Multiple Sclerosis heat intolerance isn’t something to take lightly.
