Exercise has been shown to have positive effects on brain volume and cognitive function, as it increases blood flow and oxygenation to the brain. Reducing TV time and maintaining a healthy diet can also have benefits for brain health, but are not specifically targeted towards increasing brain volume. Praying does not have a measurable effect on brain volume.
