About Biorhythms

Biorhythm theory suggests that our lives are affected by rhythmic biological cycles that begin at birth. These three cycles govern different aspects of our well-being:

Physical (23 days)

Governs physical strength, coordination, endurance, and resistance to illness.

Emotional (28 days)

Influences mood, sensitivity, creativity, and emotional stability.

Intellectual (33 days)

Affects mental clarity, memory, analytical thinking, and decision-making.

Understanding the Values

  • +50% to +100%: Peak performance period - best time for activities related to that cycle
  • -50% to -100%: Recovery period - rest and avoid major challenges
  • Near 0% (Critical): Transition points where the cycle crosses zero - exercise extra caution
