The Science Behind 15-Minute Brain Workouts
You may wonder: can just 15 minutes a day really make a difference? The answer is yes.
Cognitive psychology research supports spaced practice: short, regular training sessions often yield more retention than long, infrequent ones.
Neuroplasticity studies show that consistent mental challenges encourage brain networks to reorganize and strengthen over time.
Even brief mindfulness or meditation sessions have been shown to improve focus and reduce anxiety.
So the formula is simple: Consistency > Duration.
FAQs
