Living with MS
Heat Sensitivity
What it is
Heat sensitivity is the tendency for MS symptoms to get worse when your body temperature rises. Warm weather, hot showers, fevers, and intense exercise can all trigger it. Cooling off usually brings symptoms back to your normal baseline.
Why it matters for you
Many people with MS notice patterns around heat, especially in summer. Understanding this term explains why cooling, timing, and hydration often come up in MS symptom conversations.
