Exercise Enhances Mood
Studies have demonstrated that engaging in regular exercise can significantly improve one’s mood and act as an effective treatment for depression. Through prolonged, low-intensity exercise, the brain releases protein growth factors that stimulate the growth of nerve cells and the formation of new connections. In individuals with depression, a reduced size of the hippocampus, the brain region responsible for regulating mood, has been observed. However, exercise can contribute to the growth and connectivity of nerve cells in the hippocampus, potentially alleviating symptoms of depression.
Lowers Dementia Risk
There is growing evidence to suggest that engaging in regular aerobic exercise can significantly decrease the risk of developing dementia and cognitive impairment. Researchers believe that the benefits of exercise on brain health may be attributed to its ability to slow down age-related changes in the synapses and maintain healthy blood flow.
Ongoing research is being conducted to explore the impact of exercise on Alzheimer’s disease. One study found that individuals with Alzheimer’s who engage in regular exercise experience improved blood flow and exhibit a larger hippocampus, a region of the brain associated with memory and learning. It is worth noting that physical inactivity is considered the most common preventable risk factor for Alzheimer’s disease.
