Exercise Supports Cognitive Health After 40

Exercise supports the brain not only by increasing blood flow, but by activating a whole-body communication network between muscles, metabolism, the immune system and the nervous system.

After 40, this matters even more. Cognitive complaints such as brain fog, poor concentration and mental fatigue often do not come from the brain alone. They can reflect sleep disruption, stress load, under-recovery, metabolic changes, low muscle mass, poor nutrition or the wrong exercise dose.

This article looks at how movement supports cognitive health in midlife, and why the best approach is not to focus on one factor, but to understand the whole system.
