Broken Cellular Clock Accelerates Brain Aging
1Disrupting the 24-hour cellular clock rapidly accelerates brain aging.
2Ajou Univ. found broken clocks increase dementia proteins and brain shrinkage.
3Regular biorhythms are essential for protecting brain health, beyond mere rest.
📖 Easy Explanation
🔍 Background
Every cell in our body has a 'biological clock' that regulates activity according to day and night. A research team at Ajou University Hospital studied skin cells to see what happens to our brain when this tiny clock breaks down.
📌 Key Points
The study showed that the further the cellular clock deviates from a 24-hour cycle, the faster the brain ages. Toxic proteins causing dementia accumulated more, the brain area responsible for memory visibly shrank, and cognitive function declined faster.
💡 Why It Matters
It means that a disrupted daily rhythm can sicken our brain cells, not just cause fatigue. Living regularly by eating at consistent times and getting sunlight daily can be the strongest shield against brain aging.
