The theory of "three biorhythms" is more than a hundred years old. Three scientists became the authors of this interesting idea: Herman Swoboda, Wilhelm Fliess (who discovered emotional and physical biorhythms) and Fredric Telcher, who studied intellectual rhythm.
Psychologist Herman Swoboda and otologist Wilhelm Fliess are considered to be "the grandfathers" of the theory of biorhythms. They, independent from each other, received the same results in their investigastions. Such happenings are very rare in science.
Swoboda worked in Vienna. Analyzing the behaviour of his patients this scientist observed that their thoughts, ideas, impulses to the actions and creative impulses recurred at a certain frequency. But Herman Swoboda went further and started to analyze the beginning and development of different illnesses. The scholar was especially interested in the periodicity of heart and asthmatic attacks. As the result of all his investigations the rhythm cycles of physical (22 days) and emotional (27 days) processes were discovered.
Doctor Wilhelm Flis lived in Berlin and studied the body's resistance to illnesses. Why do children with the same diagnoses have immunity one day, but the next day they die? Having gathered enough information about the beginning of illness, temperature and death, Flis connected it with birth data. Calculations showed that declines and increases in immunity may be predicted with the help of the 22-day physical and 27-day emotional biorhythms. Fridric Telcher, a teacher from Innsbruck (Austria), became the father of the theory of "three biorhythms". The new fashionable idea prompted the scientist to do his research. In his experiments Telcher noticed, that students' ability to perceive, systematize, use information and express new ideas can decline and increase from time to time. Thus this ability has rhythmical character. Having compared data about birthdays, days of exams and their results, Telcher discovered an intellectual rhythm, which lasts 32 days.
Telcher investigated creative people's lives and found out that the time between pulse beats of our intuition is 37 days, but during the course of time this rhythm was lost. It is difficult for every new research work to find its way to acceptance in the world. Though the founders of the three biorhythms idea received the same results in their work independently, they had a lot of opponents and adversaries. Biorhythmic research spread in Europe, the USA and Japan. It became more intensive and popular in the computer era. In the 70's and 80's the idea of biorhythms conquered the whole world. The fashionable idea of biorhythms is passing by, but everything in nature has the power to repeat itself once again.
