The hippocampus is a critical brain region involved in learning and memory. It is particularly vulnerable to age-related deterioration, which can lead to cognitive impairments and conditions such as Alzheimer’s disease. Studies have shown that maintaining or increasing hippocampal volume can help mitigate these risks.

Discover the four overlooked factors your prescriptions were never designed to address—and why they may still affect how you feel.
How Aerobic Exercise Affects the Brain
Aerobic exercise, defined as any sustained physical activity that raises heart rate, has been shown to:
- Increase Hippocampal Volume: Regular aerobic activity can lead to a 2% increase in hippocampal size, effectively reversing age-related volume loss by 1 to 2 years.
- Boost BDNF Levels: Exercise stimulates the production of BDNF, a protein that supports neuron growth and survival, enhancing synaptic plasticity and overall brain health.
