Insights: 5 Reasons Fragrances Trigger Migraines

That perfume, scented candle, or cleaning spray you barely notice… could it be quietly triggering your migraines?

In this episode of Migraine Heroes Podcast, host Diane Ducarme explores why fragrances and strong smells can overwhelm the migraine brain and overstimulate the nervous system.

From perfumes and detergents to air fresheners and beauty products, we uncover how modern fragrances may impact your brain, hormones, and migraine threshold.

You’ll discover:
💡 Why your brain reacts so strongly to certain smells and what it reveals about your migraine threshold
💡 The hidden chemicals in fragrances that may overstimulate your nervous system
💡 Simple, practical ways to reduce scent-triggered migraine attacks

This episode blends neuroscience and holistic wisdom to help you better understand scent sensitivity and protect your brain from unnecessary triggers.

If certain smells instantly make you feel foggy, nauseous, or headachy — this episode is for you.

For women, men, and children who suffer from migraine disease, Migraine Heroes is your go-to resource for understanding, managing, and overcoming migraine attacks.

We cover all types of migraines and related headaches, including primary and secondary migraines, chronic migraines, and cluster migraines. We dive deep into the complexities of migraine with aura and migraine without aura, as well as rarer forms like hemiplegic migraine, retinal migraine, and acephalgic migraine (silent migraine). Our discussions also extend to cervicogenic headaches, ice pick headaches, and pressure headaches, which often mimic migraine or contribute to overall migraine burden.
