Can brief physical activity affect our ability to remember and process information? Research indicates that exercise not only benefits the body, but also the mind. The effects can last up to 24 hours after the activity. 

Effects of exercise on cognitive function 

A team of researchers from University College London (UCL) conducted a study that included 76 people between the ages of 50 and 83. The participants, exercising moderately or intensively, were monitored for physical activity and given daily memory tests. The results showed that those who were more active, while getting at least six hours of sleep a night, performed better on memory tests. Particularly noticeable was the improvement in short-term memory performance, and the positive effects of activity persisted throughout the 24-hour period. 

Exercise, such as brisk walking, dancing or climbing stairs, can speed up the heart rate and activate the brain to work more efficiently. In addition, regular exercise improves cognitive abilities, concentration and decision-making skills. According to the specialists at the National Institute on Aging (NIA), physical activity can also reduce stress levels and improve sleep quality, which indirectly affects brain function. 

Importance of sleep and rest 

Studies emphasize that a key element that supports brain function after exercise is sleep. It is during sleep that regenerative processes take place, including memory consolidation. The deep phases of sleep are particularly important for consolidating new information and regenerating the nervous system. 

Physical activity does not require complicated training plans or expensive equipment. Even simple activities, such as walking after dinner or dancing to your favorite music, can be beneficial. The authors of the Physical Activity Guidelines for Americans point out that as little as 150 minutes of moderate physical activity per week can significantly improve both physical and mental health. 

Movement for better mood 

It’s not just memory and concentration that benefit from exercise – physical activity also affects our mood. Regular movement lowers levels of cortisol, known as the stress hormone, and increases the production of endorphins. These are responsible for feelings of happiness and relaxation after exercise.
