Do you really know? Can naps keep the brain healthy?
Jul 5, 2025
Napping might be more than just a midday treat—it could be a boon for your brain! Recent research shows that genetically predisposed nappers may enjoy larger brain volumes, potentially shielding them from cognitive decline. The discussion dives into how napping can help prevent brain shrinkage linked to neurodegenerative diseases. Curious about the best conditions for an optimal nap? They’ve got tips on that too, blending science with practical advice for a healthier brain!

Episode notes
Napping and Brain Volume
- People genetically predisposed to frequent napping have larger brain volumes compared to those who do not nap regularly.
- This suggests napping may protect against brain shrinkage tied to cognitive problems and neurodegenerative diseases.
Optimal Nap Duration and Caution
- Take naps between 30 and 90 minutes to benefit cognition without affecting nighttime sleep.
- Be aware napping might reflect brain health rather than cause larger brain volumes.
How Naps Protect Brain
- Napping may clear metabolic waste from the brain, preventing neuron damage over time.
- It may also promote new brain cell and synapse production, countering age-related brain tissue loss.
