What Are Biorhythms?
Biorhythm theory suggests that our lives are influenced by three natural cycles that begin at birth: the physical cycle (23 days), emotional cycle (28 days), and intellectual cycle (33 days). Each cycle oscillates between positive and negative phases in a sine wave pattern.
When a cycle is in its positive phase, that aspect of your being is at its strongest. Critical days, when cycles cross zero, are considered times of heightened instability and potential vulnerability.
