Which disease commonly presents heat sensitivity during exercise and benefits from cooling strategies?

• A. Asthma.
• B. Parkinson's disease.
• C. Multiple sclerosis.
• D. Pulmonary hypertension.

Answer: (C)

Heat sensitivity during exercise is a hallmark feature of multiple sclerosis. In MS, demyelinated nerves conduct signals more slowly, and when body temperature rises, conduction worsens further, causing temporary increases in fatigue, weakness, numbness, vision changes, and coordination problems. Cooling strategies help by lowering core and skin temperature, which improves nerve conduction and reduces these exaggerated symptoms during activity, making exercise more tolerable and safer. The other conditions listed don’t typically show this heat-related worsening that cooling can alleviate. Asthma centers on airway constriction during exertion; Parkinson’s disease involves motor symptoms from dopaminergic loss without a heat-triggered decline in function; pulmonary hypertension relates to circulatory and breathing strain, not heat-induced neuromuscular impairment.
