What’s biorhythm?

Biorhythms are theoretical patterns that regulate the human body and mind, divided into emotional, mental, and physical cycles. Calculation is based on the number of days lived, with cycles lasting 28, 33, and 23 days. The accuracy of biorhythms is debated, but some businesses use them to determine employee performance. Software and devices exist to track biorhythms.

A biorhythm is a theoretical process by which the human body and mind are regulated according to pre-established patterns. Biorhythms are usually separated into three distinct groups: the emotional, mental and physical cycles. Classically, the lengths of these cycles are 28 days, 33 days, and 23 days, respectively.
Calculation of one’s biorhythms is obtained by dividing the number of days a person has lived by the cycle of the biorhythm being calculated. The remainder represents how far into the current cycle you are. Biorhythms are thought to follow a regular wave, swinging back and forth over the length of the cycle. On the first day of the cycle, a person is thought to be at an optimal level of functioning, while at the lowest point, a person is seen as being at their worst possible level of functional ability.

The practice of tracking the body’s biorhythm dates back to the late 19th century, when a number of physicians began observing what they perceived as repeating cycles in a range of immune system disorders and weaknesses. The lengths of the biorhythm cycles date from this period and are based on the first observations of these doctors.

Whether or not the protoscience of biorhythms is accurate is a matter of debate. While there is scientific evidence for a number of biological cycles – such as the circadian rhythm that regulates our body’s understanding of the day or a woman’s menstrual cycle – the transition from these familiar rhythms to a more generalized affective biorhythm is disputed by many. scientists. Critics point out that cycle lengths seem somewhat arbitrary, that a biorhythm is highly unlikely to be the same for all people, that most of the “evidence” presented is in fact merely anecdotal, and that a number of other Key assumptions appear to be taken as leaps of faith rather than based on hard facts.

A number of business entities use biorhythm factoring to determine when their employees will be at their best and least likely to make mistakes. A number of airlines, for example, have experimented with or currently use biorhythm monitoring to indicate days when their pilots need to expend extra energy to maintain focus and alertness, to compensate for an ebb in their biorhythm. .

There are many software applications to help people track their biorhythms, based on their date of birth and the current date. These programs allow users to project forward to see when their optimal activity days will be, particularly when all three of their cycles align at a high level of functioning. Some watches, personal digital assistants (PDAs), cell phones, and other portable devices also include rudimentary biorhythm calculators.
