Exercise for Memory Enhancement

Exercise, particularly cardiovascular exercise, has a positive impact on memory. It can improve focus, attention, and reaction time. Acute effects of exercise include a mood boost, improved prefrontal function, and enhanced reaction time. Regular exercise also promotes the growth of new brain cells in the hippocampus, which is crucial for memory formation. Even a short 10-minute walk can have immediate mood-boosting effects. Long-term effects of exercise include reducing anxiety, depression, and hostility, as well as improving performance on cognitive tasks. Exercise early in the day may be especially beneficial for mood and cognitive function throughout the day.
