BIORHYTHM

What is Biorhythm?

Biorhythm is a theory that calculates three cyclical waves as sine curves from a person’s date of birth — physical (23 days), emotional (28 days), and intellectual (33 days) — and reads a given day’s condition from the state of those waves. It was proposed in the West in the early 20th century, but no scientific basis for it has been confirmed.

Origins & History

Biorhythm is a theory built on the cyclical framework proposed in the late 19th and early 20th centuries by the German physician Wilhelm Fliess and the Austrian psychologist Hermann Swoboda, later expanded with the addition of an “intellectual cycle.” It holds that every person has three waves originating from their date of birth — physical (a 23-day cycle), emotional (a 28-day cycle), and intellectual (a 33-day cycle) — each tracing a sine curve that continues throughout a person’s life.

It became widely popular in the United States in the 1970s, becoming established as part of popular culture as dedicated calculating devices and books spread. However, multiple studies examining the theory have found no significant relationship between the cycles and actual physical or emotional states, and it is treated as a pseudoscience with no confirmed scientific basis.

How It Works

1. 01Prepare your date of birth and the date you want to read.
2. 02Calculate the three cycles — physical (23 days), emotional (28 days), and intellectual (33 days) — starting from the date of birth.
3. 03Determine where the specified date falls within each cycle (rising, falling, or at a turning point).
4. 04Read the day’s condition and points of caution from the combination of the three waves.

What It Reveals

This is well suited to intuitively grasping a rough sense of physical, emotional, and mental condition on a given day through cyclical waves. At the same time, it should be noted that this theory is a pseudoscience with no confirmed scientific basis, and its accuracy in predicting actual condition or fortune has not been demonstrated.
