What are Biorhythms?
Biorhythms are natural biological cycles believed to influence our physical, emotional, and intellectual state from the moment of birth. According to the biorhythm theory, humans are governed by three primary cycles: Physical (23 days), Emotional (28 days), and Intellectual (33 days). Tracking these cycles can help you understand why you feel more energetic, moody, or focused on certain days.
The Three Cycles
Each cycle follows a sine wave. When the wave is high, you feel at your peak in that area. When it's low, you may feel depleted. The most critical days are 'crossing days' when the cycle transitions from positive to negative, often leading to instability or accidents.
