A recent study from University College London has found that engaging in 30 minutes of moderate to vigorous physical activity, combined with at least 6 hours of sleep, can improve cognitive performance the following day. The study, which tracked the activity and sleep patterns of 76 adults aged 50-83, found that each 30-minute increase in physical activity corresponded to a 2-5% increase in episodic and working memory scores the next day. Additionally, sleeping at least 6 hours a night was linked to higher scores for episodic memory, attention, and physical response speed the next day. The study's findings suggest that physical activity may have a lasting impact on cognitive function, beyond the initial benefits, and the researchers plan to conduct further studies to explore the long-term benefits of exercise on cognitive function, particularly in people with cognitive impairments.
