What is the hallmark indicator of heat intolerance compared to normal discomfort?

Answer

A disproportionate reaction to mild increases in temperature

Heat intolerance is defined by a sensitivity that goes beyond what is typical for most people in the same environmental conditions. While everyone feels some discomfort when temperatures rise, individuals with heat intolerance experience significant distress, such as intense sweating, nausea, or dizziness, very quickly. A key sign is that this reaction happens far more rapidly and severely than it would for someone without the condition, often triggered by only mild increases in temperature that others would find manageable.
