Biorhythms — The Three Cycles of Body, Emotion, and Intellect
Biorhythm is a theory holding that, from the moment a person is born, three rhythms rise and fall on fixed cycles. It is a playful self-care tool for lightly gauging, through the flow of these rhythms, why your condition is good today or why it feels low.
What Is Biorhythm?
Biorhythm is a concept formulated from the late 19th to the early 20th century, holding that waves of fixed cycles flow through a person's body and mind. Taking the day of birth as the starting point, you count how many days have passed until now and plug that day count into each cycle to plot today's rhythm position as a sine curve. When the curve is above the line it is a high phase; below the line, a low phase.
The Three Cycles
Biorhythm consists of three rhythms. The physical rhythm, on a 23-day cycle, represents stamina, vitality, and health; the emotional rhythm, on a 28-day cycle, represents mood, sensitivity, and relationships; and the intellectual rhythm, on a 33-day cycle, represents thinking, focus, and judgment. Because the three rhythms rise and fall at different speeds, some days go crosswise — your body feels good while your heart sinks, for instance.
High Phases, Low Phases, and Critical Days
In a high phase, when a rhythm is in the upper part of its curve, the power of that area is well expressed; in a low phase below the line, it is wise to conserve your condition and mind your recovery. In particular, the point where the curve crosses between high and low — the day a rhythm passes through zero — is called a 'critical day.' On such days that area tends to become unstable, so it is better to avoid strained decisions or activity.
How to Make Use of Your Rhythms
Biorhythm is good for gauging the day's condition in advance and planning around it. Schedule exercise or important events on days when your physical rhythm is high, and place exams or work that demands focus on days when your intellectual rhythm is high. On days when your emotional rhythm is low you can grow more sensitive, so it is also wise to take care against friction with others.
Self-Care for Fun
Biorhythm is not a theory strictly proven by science, so it is better taken not as an absolute prediction but as an occasion to look back on your own body and mind. Even on a day when the rhythms are low, you can make it a fine day depending on your resolve. Biorhythm is a light reference tool that helps you attend to yourself a little more carefully.
