A new study published in the journal Imaging Neuroscience suggests that running at a slow pace for just a few minutes can improve mood and enhance certain brain functions. Researchers from Tsukuba University in Japan conducted the study with 24 healthy young adults who ran on a treadmill for 10 minutes at a pace of about 3 to 6 km/h, which is considered slow. Participants who engaged in this light running reported feeling more cheerful and alert compared to those who remained sedentary. They also performed better in tests measuring attention and self-control. The researchers used special helmets to monitor changes in oxygen levels in the brain. They observed that two areas of the prefrontal cortex — a region associated with mood, attention, and reasoning — showed increased blood flow during cognitive tasks. This suggests that even a brief, low-intensity run can lead to measurable changes in brain activity linked to improved mental performance. While the study does not advocate for everyone to slow down their running pace, it highlights the potential benefits of light exercise for mental well-being and cognitive function. The researchers note that slow running, which requires minimal physical exertion, could be a practical option for people who find traditional running unappealing but still want to gain some health benefits. The findings offer a new perspective on the relationship between physical activity and brain health. They suggest that even small amounts of exercise can have meaningful effects on mood and mental clarity, potentially encouraging more people to incorporate some form of movement into their daily routines.
