Reduced blood flow to the brain
When blood flow to the brain is reduced or interrupted, the brain will not be provided with enough oxygen and necessary nutrients. This is also one of the causes of vascular dementia.
A sedentary lifestyle can impair cerebral blood circulation, thereby increasing the risk of neurodegeneration. Conversely, regular physical activity helps improve circulation, supporting the supply of oxygen and essential nutrients for the brain.
Increased risk of cardiovascular disease
Physical activity plays an important role in improving cardiovascular health, helping to control blood pressure, cholesterol and blood sugar. Meanwhile, sedentary lifestyle increases the risk of high blood pressure, obesity, diabetes and sleep apnea - factors related to the risk of dementia.
Changes in brain structure
Lack of physical activity is associated with hippocampal atrophy - a brain area important to memory. Maintaining moderate to vigorous physical activity for about 150 minutes per week is recommended because it can help maintain brain volume and slow down brain atrophy.
Increased chronic inflammation
Lack of exercise also increases mild chronic inflammation in the body. This condition is associated with many diseases, including dementia. Maintaining regular physical activity is believed to help reduce inflammation and support maintaining thinking, learning and judgment.
