Rising Temperatures and MS Symptoms

People with MS often experienceworsening symptomswith an increase in body temperature.

The autoimmune disorder attacks myelinthe sheath that protects nerve cells and ensures signals are quickly passed between them.

Signals may be able to travel through the nervous system even with low levels of myelin.

But under some conditions, like a spike in body temperature, nerve impulses are blocked.

I don’t think it’s surprising, Sicotte says.

We definitely see people suffering more when the weather gets hotter.

These population-based studies are helpful in actually identifying trends that would be hard to see, Sicotte says.

Such a large-scale retrospective study can indicate a link between temperature and MS symptoms.

But Elser says the data really only captures the subset of patients with serious symptoms.

People with MS who experience symptoms but do not seek treatment were likely missed in this study.
