What are Biorhythms?

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.

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 a biorhythms reading you will know this and can plan accordingly.

So if you're feeling ecstatic, sad, energized or unmotivated, but you don't know why--it could be your biorhythms!

What does the chart mean?
The middle line represents your biorhythm values at birth--zero. Cycles above that midpoint are positive, and cycles below the midpoint are negative. A critical day occurs when your biorhythm cycles cross the zero line on the ascent or descent. On critical days, performance in the affected cycles might be particularly poor--so watch out!

Emotional Cycle: governs the nervous system, which is also called the "sensitivity rhythm". What are the symptoms of the Positive and Negative Emotional Stages? For the Positive Emotional Stage, you will feel great creativity, lovingness, and warmth. Also, you will probably be more open in your relationships. For the Negative Emotional Stage, you're inclined to feel withdrawn and less cooperative. You may also feel very irritated and negative about those things that occur in your daily life.

Physical Cycle: affects the physical aspect of the body, including your energy level, resistance, and overall physical strength and endurance. What are the symptoms of the Positive and Negative Physical Stages? For the Positive Physical Stage, you will feel at your best. You will feel physically fit to work on projects requiring physical strength and endurance. For the Negative Physical Stage, you are likely to have less energy and less vitality. Be sure to follow this cycle if you require physical endurance for either sports or work.

Intellectual Cycle: believed to originate in the brain. What are the symptoms of the Positive and Negative Intellectual Stages? For the Positive Intellectual Stage, you will be more intellectually responsive; you're open to accepting and understanding new ideas, theories and approaches. For the Negative Intellectual Stage, you're much more likely to have difficulty grasping new ideas and concepts.
