The Biorhythm Theory

The Biorhythm Theory suggests that our physical, emotional, and intellectual states follow cyclical patterns throughout the day, month, and year. These cycles are believed to influence our energy levels, mood, and cognitive abilities, with each cycle having a specific duration—about 23 days for physical, 28 days for emotional, and 33 days for intellectual. According to the theory, tracking these cycles can help predict optimal times for activity, decision-making, or rest. While some find it interesting for personal awareness, scientific evidence supporting biorhythms' predictive power remains limited.
