The sleep Foundation article explores the bidirectional relationship between exercise and sleep, highlighting how regular physical activity can enhance sleep quality and, in turn, support brain health and cognitive performance. Engaging in moderate aerobic exercise has been shown to increase slow-wave sleep, the deep sleep phase essential for memory consolidation and overall cognitive function. Exercise also helps regulate circadian rhythms, promoting consistent sleep patterns. While vigorous exercise close to bedtime may disrupt sleep for some individuals, moderate activity earlier in the day is generally beneficial. To optimize brain health, incorporating regular physical activity into one's routine is recommended, as it not only improves sleep quality but also directly enhances cognitive abilities. These insights are supported by current scientific research, underscoring the importance of exercise in maintaining both sleep health and cognitive function.
