ABSTRACT
This chapter explores a variety of domains that are considered part of brain health particularly as they are related to the important role of physical activity in preserving brain health. The positive effects of physical activity on cognition have been observed in studies involving multiple stages of the lifespan and are particularly present in young children and older adults. According to the Physical Activity Guidelines for Americans Advisory Committee 2018 Scientific Report 2018 Scientific Report, moderate evidence exists associating greater amounts of physical activity with improvements in cognition. Moderate evidence exists to indicate that increased PA improves cognitive function in individuals with other diseases or disorders impairing cognitive function including ADHD, schizophrenia, multiple sclerosis, Parkinson's disease, and stroke. Physical activity plays an important role in enhancing affect and decreasing anxiety and tension. In adults, physical activity has been shown to improve various sleep outcomes across young, middle aged, and older men and women.
