@EZAELECTRA This app is pretty useful to keep track of it. It's called meteoagent. As for those lines I don't know exactly what they do or mean, but I've felt weird/off for a bit now.
The correlation between geomagnetic activity and the human nervous system function was identified in 2017 through continuous monitoring of heart rate variability (HRV) and the changing geomagnetic field over a 31-day period.
... geomagnetic frequencies (Alfvén waves) or the extremely low-frequency standing waves in the Earth-ionosphere resonant cavity (Schumann resonances), which align with physiological rhythms.
