Research using neuroimaging and blood flow measurements shows that swimming enhances cerebral circulation more strongly than many types of land-based physical activities.

According to scientists, it can increase blood flow to the brain by approximately 14% compared to running — largely due to controlled breathing, full-body engagement, and sustained cardiovascular load. Enhanced circulation improves oxygen delivery to the brain, supports cognitive functions, and promotes neuroplasticity.

Therefore, experts often describe swimming not merely as an aerobic workout but as a comprehensive neurological stimulation of the entire body.

In Turkey, the fertility rate has dropped to 1.38, which is significantly below the population replacement level and even lower than in some wealthy Western countries such as the United States, France, and Denmark.
