According to biorhythms theory, our lives are affected by three primary cycles: Physical, emotional and intellectual. The cycles start at a middle point at birth, and then go up and down from this point at different rates throughout our lifetimes. Some people report that they can improve the quality of their life by monitoring these highs and lows.
Biorhythm measurements are an attempt to predict various aspects of a person's life through simple mathematical cycles. The notion is now considered a classic example of pseudoscience by modern science.
Biorhythm charts illustrate the principle that we are influenced by physical, emotional, and intellectual cycles. Many people report that they can improve the quality of their lives by monitoring the highs and lows of these cycles and acting accordingly.
The belief in biorhythms is based more on numerology, testimonials and the Forer effect, mass media hype, and intuition than on scientific study.
Generally, the more high or positive a given cycle is at any given time, the better one can interact in the related arena. The reverse is true during low or negative points of a cycle. If you are at a negative point, you can still perform well in the affected area, but it will just be more difficult. But with biorhythms reading you will know this and can plan accordingly.
At the moment of birth, the biorhythmic cycles are set to zero. Knowing your birthday, the number of days you have lived and where in each cycle you are can be determined for any given day.
So if you're feeling ecstatic, sad, energized or unmotivated, but you don't know why - it could be your biorhythms!
