Exercise and Sleep: Key to Boosting Memory in Adults

This Web Story explores how exercise and quality sleep improve cognitive performance, especially memory, for older adults. A study by UCL highlights the lasting benefits of physical activity and deep sleep on brain health. Image Source: Canva

Exercise Boosts Brain Function

Exercise provides a short-term cognitive boost, improving memory performance. A recent study by University College London found that physical activity enhances brain function, with benefits lasting up to 24 hours, especially for older adults. Image Source: Canva

Study by UCL Researchers

The study, published in the International Journal of Behavioral Nutrition and Physical Activity, was led by Dr. Mikaela Bloomberg from UCL. It investigated how physical activity and sleep impact memory in adults aged 50 to 83. Image Source: Canva

Memory Benefits from Exercise

The research found that engaging in moderate to vigorous physical activity improves memory performance the next day. Adults aged 50 to 83 who exercised more than usual scored better on memory tests the following day. Image Source: Canva

Sleep Enhances Memory Function

Deep (slow-wave) sleep was found to significantly improve memory performance. The study showed that increased deep sleep contributed to better next-day memory, reinforcing the connection between restorative sleep and cognitive health. Image Source: Canva

Impact of Sedentary Behaviour

Less time spent sitting was associated with better memory function. The study highlighted that prolonged sedentary behaviour negatively affects memory, especially working memory, demonstrating the need to stay active for brain health. Image Source: Canva

Micro-Longitudinal Study Approach

This research used a “micro-longitudinal” study design, tracking participants in their everyday environments with wrist-worn activity trackers. This approach offered more accurate results than traditional lab-based studies, reflecting real-life activity patterns. Image Source: Canva

Moderate Activity Improves Memory

Brisk walking, dancing, and climbing stairs are examples of moderate activities linked to improved memory. The study showed that even non-structured physical activity helped enhance cognitive performance the following day. Image Source: Canva

Deep Sleep Enhances Cognition

The study found that slow-wave sleep plays a crucial role in memory function. The more time participants spent in deep sleep, the better their episodic memory, suggesting that restorative sleep aids cognitive health. Image Source: Canva

Exercise and Mood Improvement

Physical activity not only enhances memory but also improves mood. Evidence suggests that exercise can enhance mood for up to 24 hours, with neurochemical changes, such as dopamine release, contributing to cognitive well-being. Image Source: Canva

Cognitive Health Implications

Maintaining cognitive health is crucial for older adults. The study indicates that regular physical activity, combined with good sleep, could significantly improve short-term cognitive performance, which may support long-term brain health and reduce dementia risk. Image Source: Canva
