Roughly one in seven people worldwide lives with migraines. Yet when someone asks what sets theirs off, most of us blame stress, skipped meals, or a bad night's sleep.

Here's what rarely gets mentioned: the room you're sitting in right now may be doing more than you think.

Researchers and neurologists have long noted that chronic migraine is rarely caused by a single thing. It tends to build up from small, ordinary exposures that add up over a day:

The flicker of overhead fluorescent lighting at the office

Glare from a screen you've stared at for hours

A scented candle, cleaning spray, or perfume that seems harmless

Shifts in barometric pressure and indoor temperature

A dehydrating, stuffy room with poor ventilation

None of these looks dangerous on its own. That's exactly why they're so easy to overlook. People who track their migraine triggers in a simple diary often find that the pattern was hiding in plain sight, tied to a place, a time of day, or a routine.

And there's one everyday setting that surprised me more than the others. It's somewhere most of us spend a big chunk of our week, and it barely gets a mention in typical migraine advice. Once you know what to look for there, small changes may make a real difference to how your days feel.

I've laid out the full breakdown, including that overlooked environment, in the article below. As always, if your headaches are frequent or severe, please talk with a qualified healthcare professional. This is general information, not medical advice. 💡
