Many of us are aware that intense physical activity often leads to sore muscles the next day.

However, researchers have found that the advantages for the brain can also be experienced after a full day.

University College London Researchers from UCL discovered that the temporary cognitive enhancement our brain experiences after exercising lasts for the entire subsequent day.

Individuals who engaged in a higher amount of moderate to intense physical exercise compared to their regular routine performed better on memory assessments the following day.

Specialists mentioned that these enhancements might be accomplished through a straightforward activity like sprinting upstairs.

In the short term, exercise increases blood flow to the brain and stimulates the release of neurotransmitters such as norepinephrine and dopamine which help a range of cognitive functions.

These neurochemical alterations are known to persist for several hours following physical activity.

However, other studies have shown brain states linked to exercise were more long-lasting, with evidence suggesting exercise can enhance mood for up to 24 hours.

Individuals between the ages of 50 and 83 wore fitness monitors for eight consecutive days and completed cognitive assessments daily.

Researchers examined the duration of time participants spent being sedentary, engaging in light activities, and undertaking moderate or intense exercises.

They also measured the amount of sleep and the time allocated to lighter stages like rapid eye movement (REM) sleep as well as deeper, slow-wave sleep.

When considering typical daily activities and rest periods, the study revealed that engaging in a higher amount of moderate or intense exercise than usual was associated with improved working memory and episodic memory—the recollection of personal experiences—on the following day.

These advantages were experienced by individuals who sat for shorter periods and slept for six hours or more.

Increased total sleep duration was associated with better performance in episodic and working memory as well as enhanced psychomotor speed, which assesses how swiftly an individual perceives and reacts to their surroundings.

According to the research published in the International Journal of Behavioral Nutrition and Physical Activity, individuals who experienced more slow-wave—deep, recuperative sleep—showed improved episodic memory.

On the contrary, spending more time being inactive than normal was associated with a decline in working memory the following day.

Dr. Mikaela Bloomberg from UCL stated, "Our research indicates that the positive impact of physical activity on short-term memory might extend over a longer period—possibly up to the following day rather than only for several hours post-exercise. Additionally, increased quality sleep, specifically deep sleep stages, appears to enhance this memory boost."

'Moderate or intense physical activity refers to anything that elevates your heartbeat - examples include quick-paced walking, dancing, or climbing several flights of stairs. This does not necessarily require formal workout routines.'

'This was a limited study, and therefore it should be repeated with a bigger participant group to ensure the reliability of the findings.'
