Frequently asked questions
Do a lot of people have a headache today?
We don't have enough reports from Canada yet to show rates. The map fills in as more people log their headaches in Zutsu Note or tap "I have a headache now."
What does the real-time headache map show?
For each province or territory, it shows the share of people who logged their day in Zutsu Note and had a headache during the current part of the day (morning, afternoon, or night, in local time), plus anyone who tapped "I have a headache now" in the last 3 hours. A province or territory needs at least 10 people before we show its own rate. Until then, we use its area's rate, and gray means there aren't enough reports yet.
Does the map predict or diagnose headaches?
No. The numbers come from app users and button taps. They are not the share of everyone in the province or territory, and they don't predict or diagnose anyone's headaches. If you have a sudden, severe headache, or a headache with weakness, numbness, trouble speaking, fever, or confusion, call 911 or go to the nearest emergency department. If your headaches keep coming back or change, talk to your doctor.
Can I add my headache to the map?
Yes. Tap "I have a headache now" below the map, even if you don't use Zutsu Note. Your province or territory is found from your location on your device, and if that doesn't work, you can choose it. Your location isn't sent or saved.
How to read this map
- The map counts people in Canada who logged their day in Zutsu Note and had a headache during the current part of the day (morning 5–11 AM, afternoon noon–5 PM, night 6 PM–4 AM, in local time). It also counts anyone who tapped "I have a headache now" in the last 3 hours.
- Use the slider or tap Play to look back over the last 24 hours, hour by hour. Times are shown in your local time.
- Notes left with "I have a headache now" pop up in bubbles over the province or territory for 3 hours. Tap "All notes" to see them all, send "Me too," or report a note.
- A province or territory needs at least 10 people before we show its own rate. Until then, we use its area (West Coast, Prairies, Central Canada, Atlantic Canada, The North). Gray means there aren't enough reports yet.
- These numbers come from app users and button taps. They are not the share of everyone in the province or territory, and they don't predict or diagnose anyone's headaches.
- If you have a sudden, severe headache, or a headache with weakness, numbness, trouble speaking, fever, or confusion, call 911 or go to the nearest emergency department.
