Physical exercise increases blood flow to the brain, which promotes the creation of new brain cells and helps eliminate toxins.

This advice is based on well-documented physiological mechanisms. Research confirms that regular physical activity improves cerebral circulation, which supports the supply of essential nutrients for neuronal function. The link between exercise and neurogenesis (the creation of new cells) is widely supported by animal studies, and evidence suggests similar effects in humans via the increase of neurotrophic factors such as BDNF. The idea of "toxin cleansing" is a popularization of the glymphatic system, a cerebral purification mechanism that appears to be effectively supported by physical activity in preclinical literature. Although some mechanistic details remain complex in humans, the overall claim is firmly rooted in current knowledge on brain health.
