How does a sedentary lifestyle affect cognitive health?

A sedentary lifestyle can have a notable and detrimental impact on cognitive health. Prolonged periods of physical inactivity are associated with reduced blood flow to the brain, which can impair cognitive function.

Research, as highlighted in a study published in "Neurology" in 2019, suggests that sedentary behavior is linked to an increased risk of cognitive decline, as well as a higher likelihood of developing conditions like dementia and Alzheimer's disease.

Regular physical activity, on the other hand, has been shown to enhance cognitive function by promoting neuroplasticity, improving blood flow, reducing inflammation, and supporting the growth of new brain cells. It also helps maintain healthy weight and blood sugar levels, reducing the risk of conditions that can negatively affect cognitive health. In summary, avoiding a sedentary lifestyle is essential for preserving and promoting cognitive well-being.
