Biorhythms

Biorhythms are cyclic patterns of our physical, emotional and intellectual cycles, which repeat after a period of time.

They begin at birth and then have highs and lows throughout our lives. Biorhythm cycles are grouped into periods of 23 days (physical matters), 28 days (emotional), or 33 days (intellectual).

By charting out where you are on the scale (either, physical, emotional or intellectual), you can predict what kind of day you are likely to have. All of these cycles can be charted out and followed, like a horoscope.
