Short Bursts of Exercise Boost Cognition, Memory, and Attention Span
New research indicates that short, frequent bursts of exercise throughout the day can significantly improve cognitive functions such as working memory, attention span, and cognitive flexibility. A review of 25 randomized controlled trials, involving 1115 participants aged 8 to 78, found that 'exercise snacks'—sessions of physical activity lasting no more than 10 minutes, performed at least twice a day—provided a modest immediate boost to cognitive abilities. These exercises included activities like walking, stretching, climbing stairs, resistance exercises, stationary cycling, or high-intensity movements such as running on the spot. The cognitive benefits were more pronounced if the exercise habit was maintained for several weeks and if it occurred in school or workplace settings. The study suggests that even brief periods of movement, such as walking around or stretching every hour, can have an immediate positive impact on the brain, adding to existing evidence that exercise is beneficial for overall heal...
