Research has shown that the body and mind function according to ultra biorhythms, cycles in which the body moves from high-energy to low-energy states. At the low point of the cycle, which occurs every 90 to 120 minutes, your energy dips and your mind wanders (Schwartz). In response to this energy deficit, people usually reach for that extra cup of coffee, grab a sugary snack, or just suffer through the feeling of listless fatigue. This kind of habitual behavior in the long run only produces burnout and inefficient working habits. What people really need is an effective way to recharge their energy, rather than to push themselves artificially through the feeling of exhaustion and brain fog.
On top of this tendency, most people’s work is not balanced from the brain’s point of view. These days, most people find that their jobs require a great deal of processing from the prefrontal cortex, especially for left-brain functions, like logical, symbolic, and verbal processing.
