10 How exercise increases brain volume — and may slow memory decline

Increased Blood Flow:

Exercise promotes better blood circulation, ensuring that the brain receives an optimal supply of oxygen and nutrients.

Neurotransmitter Release:

Physical activity triggers the release of neurotransmitters like dopamine and serotonin, which play essential roles in mood regulation and cognitive function.


Exercise has been associated with the creation of new neurons (neurogenesis) in the hippocampus.

Brain-Derived Neurotrophic:

Exercise stimulates the release of BDNF, a protein that supports the growth, maintenance, and survival of neurons.

Reduction of Inflammation:

Regular exercise has anti-inflammatory effects, reducing overall inflammation in the body, including the brain.

Improved Sleep:

Regular physical activity is associated with better sleep quality. Quality sleep is crucial for memory consolidation and overall cognitive function.

Enhanced Cognitive Function:

Exercise has been shown to improve various aspects of cognitive function, including attention.

Stress Reduction:

Physical activity helps reduce stress by promoting the release of endorphins, the body's natural mood elevators. 

Improved Insulin Sensitivity:

Regular exercise improves insulin sensitivity, which is not only beneficial for metabolic health but also for brain function.

Promotion of Vascular Health:

Exercise supports the health of blood vessels, reducing the risk of vascular-related cognitive decline.
