Dementia, particularly alzheimer’s disease, is an increasingly common problem in an aging society. The disease affects millions of people worldwide, and there is currently no definitive cure. However, numerous studies confirm that regular exercise, especially cardiovascular workouts, can significantly contribute to maintaining brain function and preventing dementia. Physical activity stimulates brain blood circulation, improves communication between nerve cells, and promotes the formation of new neurons.
The connection between physical activity and dementia
Research over the past decades has shown a clear relationship between regular exercise and maintaining brain function. People who are actively involved in sports are much less likely to suffer from dementia in old age. According to a study published in the journal of alzheimer’s disease in 2018, regular exercise can reduce the risk of developing dementia by 30-50% in middle-aged individuals.
The role of cardiovascular exercise in brain blood circulation
Cardiovascular exercises – such as running, swimming, and cycling – are particularly important for maintaining brain health. These forms of exercise increase heart rate and enhance blood circulation, allowing oxygen-rich and nutrient-rich blood to flow to the brain. Proper blood supply to the brain is critical for the function and survival of nerve cells.
Studies have shown that regular cardiovascular exercise stimulates neuroplasticity, the brain’s ability to form new neural connections. This is especially important for the aging brain, where reduced neuroplasticity can lead to dementia. A 2020 study published in mayo clinic proceedings found that older adults who engaged in moderate-intensity cardiovascular exercise had better brain blood supply and cognitive functions compared to those who did not exercise regularly.
Effects of improved brain blood circulation
Better brain blood circulation promotes the oxygen and nutrient supply to nerve cells, which is essential for cell health and maintaining cognitive functions. Additionally, increased blood flow helps remove harmful substances accumulated in the brain, such as beta-amyloid plaques. These plaques are a major feature of dementia, and their accumulation contributes to the destruction of nerve cells. Therefore, physical activity not only improves brain blood supply but also helps remove harmful substances that could lead to dementia.
How to get started
Incorporating regular exercise at any age can be beneficial, but it is especially important for middle-aged and older adults. Intense workouts are not necessary to experience the positive effects; even 30-40 minutes of moderate-intensity exercise daily can significantly reduce the risk of developing dementia. Walking, swimming, cycling, or even light jogging can contribute to maintaining brain health.
