Tracing a sideways figure-8 with your eyes for a minute (the 'Lazy 8s' from Brain Gym) is marketed as a way to get both brain hemispheres working together and reset your focus in 30 seconds.

Brain Gym, whose signature moves are Lazy 8s and cross-crawl, rests on the idea that crossing the body's midline 'activates' and 'integrates' both hemispheres and thereby unlocks learning — a brain-dominance and neurological-repatterning theory that several independent systematic reviews explicitly label a neuromyth. The handful of studies claiming to validate the program have well-documented methodological flaws (no adequate control group, effects never measured beyond an immediate post-test, confounding with ordinary child maturation), and a dedicated research synthesis concludes that no quality evidence supports either the theory or the program's effectiveness — a verdict echoed by education-neuroscience researchers who list it among the myths worth retiring from classrooms. What's tucked into the rest of the post holds up considerably better: the nutrients named (omega-3, iron, B12, antioxidants) have a plausible, documented link to cognitive function without being an instant focus switch, 25-minute blocks followed by a short break echo a work-in-cycles logic that's well supported elsewhere, and morning light genuinely helps anchor circadian rhythm. The line is clear: the gesture itself (tracing an eye-8) is harmless, but the mechanism it's sold on — 'integrating the hemispheres' — is a theory that's been invalidated since the 1990s; the supporting elements of the post (nutrition, breaks, morning light) are real levers, just not discoveries unique to Brain Gym.
