Morning exercise can improve decision-making across the day in older adults. A study of older Australians has found a morning bout of moderate-intensity exercise improves cognitive performance like decision-making across the day compared to prolonged sitting without exercise. It also shows that a morning bout of exercise combined with brief walking breaks to frequently disrupt sitting throughout an eight-hour day can boost short-term memory compared to uninterrupted sitting, according to the study.
