A still sky
Nothing is happening up there tonight. The field around Earth is calm.For you: on nights like this, the sky is off the list of suspects. If you sleep badly, look at the usual causes instead: caffeine, stress, a warm room.
tonight's readings▾
Every month, someone types this into the night
We collected 717 of these posts over two years. They weren't asking for data. They were asking: am I going crazy? Is anyone else out there?
The 3am club
The most common hour in these posts is 2 to 4am. There is an ordinary explanation: melatonin peaks around 3am and cortisol starts rising soon after, so the lightest sleep window is exactly when a storm runs. And a studied one: several trials report lower nocturnal melatonin on magnetically disturbed nights. Which one is yours? The log knows. You wake at 3, you tap once, the mirror decides.
'anyone else' appears in 36+ titles. Headaches 89, sleep 44, anxiety 24.
What the science says (and doesn't)
We don't hand out answers. We hand you a thermometer. Every health claim carries its evidence grade. That is the only difference from mysticism, and it is everything.
meta-analyses
Strong storms associate with MI/stroke admissions (RR 1.3-1.5). Population patterns, not personal fate.
Evidence →cohort studies
Brazil national data: MI admissions rise on disturbed days; Qingdao cohorts' blood pressure tracks geomagnetic activity.
Evidence →the edge
No study can decide whether YOUR headache came from a storm. So: record, don't blame.
Method →Tonight, log it
Not for anyone else. Not uploaded. No fortune-telling. Just a thermometer: 30 seconds, note tonight's self. In 30 days a mirror appears, your sleep curve and the sky's curve on the same axis.
