What Are Biorhythms?
Biorhythm theory holds that your life flows in natural cycles from birth: a 23-day Physical cycle (strength and energy), a 28-day Emotional cycle (mood and sensitivity), a 33-day Intellectual cycle (logic and focus), and a 38-day Intuition cycle. Each rises and falls like a wave. High points are ideal for peak performance; low points favor rest and reflection.
Biorhythms are a fun, self-reflective tool — not a medical or scientific system. For a different lens on your daily energy, explore the Pancha Pakshi (Vedic bio-rhythm), check today's mood forecast, or plan your day with the Daily Planner.
