Research says Exercise boost memory in longterm

A recent study suggests that simple physical activities like a brisk walk, dance, or climbing a few flights of stairs may significantly boost memory, with the benefits lasting longer than previously believed. The research, conducted by University College London (UCL), found that moderate to vigorous physical activity—activities that raise the heart rate—can improve memory performance the day after the exercise, particularly for people aged 50 to 83.

While earlier studies indicated that exercise improves cognitive function for a few hours post-workout, this new study shows that the benefits can extend into the following day. Dr. Mikaela Bloomberg, the lead author from UCL’s Institute of Epidemiology & Health Care, explained that getting more sleep, especially deep sleep, enhances these memory improvements. The study’s findings, published in the International Journal of Behavioural Nutrition and Physical Activity, suggest that the short-term memory benefits of physical activity are longer-lasting than previously thought.

Exercise helps increase blood flow to the brain, stimulating the release of neurotransmitters like norepinephrine and dopamine, which play key roles in various cognitive functions. These benefits, which were once thought to last only a few hours, may now extend for up to 24 hours, similar to the mood-enhancing effects of exercise.

The research involved 76 participants who wore activity trackers for eight days and completed daily cognitive tests. Those who engaged in activities such as brisk walking or dancing saw immediate cognitive benefits, which lasted longer than expected. On the other hand, participants who spent more time sedentary experienced a decline in working memory the following day.

Although the study’s sample size was small, the results suggest that increasing physical activity and improving sleep habits could be beneficial for memory, and further research with a larger sample is needed to confirm these findings.
