The origins of biorhythm
Biorhythm theory was developed in the late 19th century by Wilhelm Fliess, a German physician, and later refined by Alfred Teltscher. The fundamental idea is that from the moment of our birth, three biological cycles begin oscillating as sine waves.
These cycles never stop, and their interaction creates unique patterns every day. It's a self-knowledge tool that helps you plan your life more consciously.
The 3 fundamental cycles
Physical Cycle (23 days): Governs your strength, endurance, coordination, and overall physical energy. On high days you feel energized to conquer the world. On low days, your body asks for rest.
Emotional Cycle (28 days): Affects your mood, sensitivity, creativity, and intuition. Interestingly, it coincides with the lunar cycle. In the high phase, you're more empathetic and creative. In the low phase, you may feel more sensitive or irritable.
Intellectual Cycle (33 days): Influences your concentration, memory, logic, and decision-making ability. In the high phase, your mind is sharp. In the low phase, complex tasks may require more effort.
Critical days
The most interesting moments in biorhythm are the "critical days": when a cycle crosses the zero axis, transitioning from positive to negative or vice versa. On these transition days, that area of your life is more unstable and requires extra attention.
A day where all three cycles are in high phase is ideal for major challenges. A day where all are in transition requires caution and self-care.
How to use biorhythm in your daily life
It's not about letting numbers control your life, but using them as an additional compass. Plan intense exercise when your physical cycle is high. Save important conversations for high emotional cycle days. Schedule exams or presentations when your intellectual cycle is at its peak.
