Heat Stroke and Migraines: The Dangerous Overlap
For people with migraine, hot weather is rarely just uncomfortable. It is often a trigger in its own right, and when an attack lands during a heat wave, several of the symptoms — nausea, photophobia, confusion, exhaustion — overlap with the early signs of heat illness in ways that can lead to dangerous misreads in both directions. A migraine attack can mask developing heat stroke. A heat illness can be dismissed as "just a bad migraine." Either mistake can have serious consequences.
This article looks at how migraines and heat illness interact physiologically, where their symptoms overlap and where they diverge, the migraine-specific factors that raise heat illness risk, and the practical adjustments that meaningfully protect weather-sensitive people during hot stretches.
