Question

Quizplus · Accepted Answer

Exercise has been shown to increase the production of growth factors in the brain, which can lead to increased brain volume and improved cognitive function. While reducing TV time and eating a healthy diet may also have mental health benefits, they do not directly increase brain volume. Praying may have a positive impact on mental health, but there is no scientific evidence to support the idea that it directly increases brain volume.
