Part 2/8:
Remarkably, significant improvements in brain health can be observed in as little as three months. Even a modest 10-minute walk has profound benefits—it can reduce feelings of anxiety and depression. This "neurochemical bubble bath" boosts mood and promotes the release of chemicals that make us feel better, more relaxed, and more alert.
For individuals who are sedentary, just engaging in a few short walks per week—around two or three sessions—can yield meaningful gains. These activities help improve baseline mood, enhance prefrontal cortex function (which governs decision-making and emotional regulation), and bolster hippocampal health (crucial for memory formation). The message is clear: even minimal activity is a powerful starting point, and it’s entirely within reach for most of us.
