Members overwhelmingly confirmed that heat sensitivity is a real and frustrating symptom of fibromyalgia, describing experiences ranging from intense facial flushing and core overheating to profuse sweating, burning sensations in the limbs, and even passing out when their bodies get too warm. Several members shared practical coping strategies including taking frequent breaks to cool down, staying hydrated, avoiding sun exposure during peak heat, dressing in layers, carrying portable fans and water, eating high-protein snacks to refuel after overheating episodes, and being mindful that certain medications can worsen heat intolerance. A recurring theme was the unpredictable and often confusing nature of temperature dysregulation in fibromyalgia, with many members describing malfunctioning internal thermostats, sudden sweating for no apparent reason, and overheating serving as a warning sign of impending pain flares or exhaustion.
