Abstract

Supplying the brain with enough blood flow is essential to keep us alive and maintain our brain health. Reductions in brain blood flow can negatively affect the ability to think. Decreased blood flow to the brain can also lead to brain diseases, such as dementia, which is a condition that causes permanent memory loss and confusion. Scientists are beginning to think that sitting may be bad for brain blood flow. Understanding how sitting affects the brain is therefore very important. We conducted a study in which participants either sat down without any breaks for 4 h, or sat down but took a short walking break every 30 min, or took a longer walking break every 2 h. After sitting without any breaks, brain blood flow decreased. However, when participants took a walking break every 30 min that prevented the decrease in brain blood flow. These results suggest we should encourage people to take regular breaks from sitting to help maintain brain health.
