What is Space Weather Check-In?
Every day, Earth is bathed in fluctuating electromagnetic fields — the Schumann resonance at 7.83 Hz, the geomagnetic field shifting under solar wind, and occasional solar storms. Research suggests these shifts correlate with sleep quality, headaches, mood, and cardiovascular stress in sensitive individuals.
