Biorhythm

Biorhythm theory was developed in the late 19th century and gained popularity in the 1970s. While scientific studies haven't conclusively proven its validity, many people find it a useful tool for self-awareness and planning.

Critical days occur when any biorhythm cycle crosses the zero line, transitioning from positive to negative or vice versa. During these days, you may feel unstable or accident-prone in that particular area.

Use biorhythm as a general guide for planning activities. Schedule demanding physical activities when your physical cycle is high. Plan important meetings when your emotional cycle is positive. Tackle complex problems when your intellectual cycle is at its peak.

The theory suggests that different aspects of our being operate on different natural rhythms. The physical cycle (23 days) is the shortest, reflecting quick recovery. The emotional cycle (28 days) aligns with lunar cycles. The intellectual cycle (33 days) is the longest, representing deeper mental processes.
