To prevent heat-related symptom exacerbation during MS exercise, what should be encouraged?

• A. Hydration
• B. Prolonged hot baths after exercise
• C. Skipping water breaks
• D. Exercising in a sauna

Answer: (A)

Hydration is crucial to prevent heat-related symptom exacerbation during MS exercise. In multiple sclerosis, heat sensitivity can worsen symptoms like fatigue and weakness when body temperature rises, a response known as heat intolerance. Keeping well-hydrated helps maintain blood volume and supports sweating and cooling, aiding the body's ability to regulate temperature during activity. Drinking fluids regularly before, during, and after exercise reduces the risk that heat will amplify symptoms and fatigue. In contrast, hot baths after exercise, skipping water breaks, or exercising in a sauna all raise core temperature or reduce cooling, making symptoms worse.
