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.

Neurogenesis:

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.
