A Brief History of Biorhythm

In the late 1800s and early 1900s there were two doctors that were instrumental in the study of biorhythm and are now considered to be the “fathers” of biorhythm theory. Dr. Hermann Swoboda was a Professor of Psychology at the University of Vienna and Dr. Wilhelm Fliess, a nose and throat specialist who was also a friend and colleague of the famous psychoanalyst, 

What was it that they discovered?

Through their medical research both doctors found that there is very definite periodicity or rhythms in our lives. Their discoveries determined that we are affected by these rhythms physiologically, emotionally and intellectually.

To this day a great number of studies are still being done regarding the effects of biorhythm on the human condition.

Although biorhythms are not an exact science, the fathers of biorhythm theory have established the fact that they do exist. After reading the work of Drs. Fleiss and Swohoda I believed that using technology (software) and a large number of subjects in a study that I could more accurately determine dates on which all of us have the greatest potential to Succeed in our chosen fields.

The research that I have done and the data that I have accumulated and continue to accumulate aren’t medical studies. My interest and studies involving biorhythms lie in three areas: The recurrence of specific performance in sports, the effect of biorhythms on the general population and instances of unusual or serendipitous luck. The bulk of my studies have been involved with the emotional cycle since I believe that this is the primary cycle for determining success in business, sports, luck and our personal lives. I believe based on the data that I collected, that the emotional

cycle generates a positive mental attitude, confidence and an energy source which appears to be derived from the cosmos with which we are all connected. You can see that when combined with a positive intellectual cycle which generates good judgment, good memory and quick decisions it can yield a human who is somewhat “super”. Secondly in importance for high levels of performance is the intellectual cycle. If combined with a positive in the Emotional cycle an individual with a double – positive has the potential for exceptional performance in any of their endeavors.

Biorhythm Energy

For biorhythms to exist some form of energy must be present within all of us. One form of energy that occurs in cycles is electricity. Biorhythms appear to be affected by “electrical” energy within our bodies. Our bodies and each cell within it have an electrical charge, indeed, even the molecules and atoms of which our bodies consist have positive and negative charges. Scientists tell us that our bodies are essentially large batteries. This supports the hypotheses which indicate the involvement of energy for the existence of biorhythm. If we accept the fact that our bodies must generate energy to function, then it follows that there are periods in which we recharge, are fully charged and we deplete our energies.

Basic Biorhythms

Biorhythm consists of three cycles: physical, emotional and intellectual (P E I). In my copyrighted software programs, BioCalendar and Teambios, I have assigned symbols and numerical values to each of the cycles corresponding to the point or day within that cycle. (See the above chart).

The physical cycle consists of 23 days; the emotional cycle 28 days; and the intellectual cycle 33 days.

Note that the biorhythm sine-wave can be viewed to be in four sections:

  • Ascending above the line: +
  • Descending above the line: #
  • Descending below the line: –
  • Ascending below the line: *

There are also symbols and values representing the Caution or Critical days as well as Mini-Cautions or Mini-critical days.

  • Ascending cycle on the line: c (small)
  • Descending cycle on the line: C (large)
  • At the peak or apogee: H
  • At the bottom or perigee: L

Generally, above the line (positive) is better than below the line (negative) in each of the cycles. The section represented by the “+” and “#” symbols are the more favorable sections and conversely, the section represented by the “*” and “-” are less favorable than the positive sections above the line. The two negative sections which exist below the line can be likened to a battery where the “-” is depleting the energy and the “*” section is recharging the energy in a battery. The “+” section is fully charged and the “#” section is somewhat less than fully charged. (See the section under GOLF which describes the effects of positive versus negative phases in 121 PGA tournaments.

physical cycle

The physical cycle affects strength, endurance, and overall energy levels. Positive phases (+ and #) support better athletic performance, while negative phases (- and *) may reduce stamina and coordination. Caution (C) and Low (L) periods can lead to fatigue, slower reaction time, and reduced immunity, making the body more vulnerable to illness.

emotional cycle

The emotional cycle influences mood, reactions, and decision-making under pressure. Caution phases may cause overreaction or heightened sensitivity, while positive extremes like H and L are often linked with unusual “bio-luck” events. These moments are believed to increase chances of success in chance-based activities, though outcomes are not guaranteed and should be viewed as probability shifts rather than certainty.

intellectual cycle

The intellectual cycle governs focus, memory, and decision-making ability. During low phases, recall and mental clarity may decline, making it harder to process information or remember details. In positive phases, thinking becomes sharper, improving concentration, problem-solving, and mental performance in both daily tasks and complex decisions.
