Understanding the Migraine Index: What Your Score Means
If you've used a weather app's health section or a migraine forecast tool, you've probably seen a "migraine index" — a single number or a low-to-high rating that's supposed to tell you how likely a weather-triggered attack is today. It's a useful idea, but only if you understand what the score is actually measuring and, just as importantly, what it isn't.
This article breaks down what goes into a migraine index, how to read a high versus low migraine index score, why two apps can disagree on the same day, and how to fold a daily migraine risk number into your routine without handing it the keys to your whole day.
