A new scientific study has revealed that brief daily cycling sessions can not only enhance cognitive performance but may also help reduce the risk of dementia in later life.

Experts suggest that cycling for approximately 17 minutes each day could be effective in this regard.

The research, conducted in the United Kingdom, involved 23 middle-aged participants who were overweight. Half of the participants followed a 12-week cycling program, while the others maintained their usual routines with little or no physical activity.

Results showed that participants who cycled regularly experienced a significant increase in levels of the chemical BDNF (brain-derived neurotrophic factor) in their blood. Often referred to as “brain food,” BDNF supports the growth and connectivity of brain cells. In contrast, those who did not exercise showed no notable change in BDNF levels.

Brain scans further revealed that cyclists displayed reduced activity in regions associated with attention and control tasks, indicating that their brains were working more efficiently. While the study did not observe a clear improvement in memory, researchers believe this may be due to the short duration of the intervention.

The study was led by Dr. Flaminia Ronca, who explained that increased physical fitness boosts BDNF production, which in turn can enhance cognitive abilities over time. Participants cycled four days a week for 30 to 45 minutes, equivalent to an average of 17 to 26 minutes of daily activity.

The program began with moderate-intensity sessions for the first six weeks, followed by increased intensity in subsequent weeks.

With dementia cases rising rapidly worldwide, experts emphasize that simple, consistent physical activity—such as short daily cycling sessions—can serve as an accessible and effective strategy for maintaining brain health.
