Prolonged Sitting Linked to Brain Shrinkage, Even With Exercise
Imagine your brain is like a muscle that needs exercise.
This study shows that sitting for too long, like when you're watching TV or working at a desk, can make your brain shrink, even if you also exercise.
Researchers looked at older people and found those who sat the most had smaller brains.
This is especially true for people with a certain gene.
Sitting too much can reduce blood flow to the brain, which isn't good for brain health.
The good news is that taking short breaks to walk around or stand up can help protect your brain.
So, move around to keep your brain healthy!
Research indicates that extended sitting can contribute to brain shrinkage.
The study examined older adults over seven years.
Participants who exercised still experienced brain volume loss from prolonged sitting.
Individuals with the APOE-ε4 gene showed greater gray matter loss.
Experts recommend short walks and breaks to mitigate risks.
- Who
- Researchers at Vanderbilt University’s Memory and Alzheimer’s Center studied older adults.
- What
- A study found that prolonged sitting can contribute to brain shrinkage and cognitive decline, even with regular exercise.
- When
- The study was conducted over a seven-year period.
- Where
- Vanderbilt University’s Memory and Alzheimer’s Center
- Why
- Prolonged sitting can lead to brain shrinkage and cognitive decline, especially in those with genetic predispositions like the APOE-ε4 gene, by impeding blood flow and increasing inflammation.
- Study Participants
- Older adults
- Average Sitting Time
- 13 hours daily (average)
- Brain Areas Affected
- Frontal and Parietal Lobes
- Genetic Risk Factor
- APOE-ε4 gene
- Recommended Exercise
