Napping, Brain Volume, and the Potential to Slow the Aging Process
Napping is a common practice in many cultures and has been celebrated for its plethora of benefits—improving mood, enhancing alertness, and boosting cognitive performance. Many of us have experienced the clarity and focus that a brief nap can provide when we’re feeling groggy or fatigued.
However, it appears that there are much greater benefits to napping:
Recent medical research has revealed that napping has a positive effect on our brain’s structure.
While it may seem unconventional, scientific studies are uncovering connections between napping and brain volume. Researchers are hoping to find that including regular naps in our busy lives could slow brain shrinkage as we age and lower the risk of dementia and other diseases.
Napping, Brain Volume, and Cognitive Health
First things first, it’s essential to understand the importance of brain volume.
Brain volume refers to the overall size of the brain, and it’s closely linked to cognitive health. A larger brain volume is often associated with better cognitive function and memory. On the flip side, a reduction in brain volume is a common characteristic of neurodegenerative diseases like Alzheimer’s, and it’s often an indicator of cognitive decline.
The idea that napping might affect brain volume emerged from a series of studies that examined the impact of sleep patterns on the brain. These studies (one published in Sleep Health can be found here) found that people who regularly took short naps during the day tended to have more significant brain volume than those who did not nap or napped infrequently. The increase in brain volume was especially noticeable in regions of the brain associated with memory and cognitive function.
One possible explanation for this link is that napping improves overall sleep quality. When we nap, we enter a lighter stage of sleep, which can help consolidate memories and enhance cognitive processes. This improved sleep quality may have long-term benefits for brain health, leading to increased brain volume.
Another theory suggests that napping may reduce stress and inflammation, which have been linked to brain atrophy and cognitive decline. Therefore, napping could help counteract these negative effects, ultimately preserving brain volume.
It’s important to note that the exact mechanisms behind the relationship between napping and brain volume are not yet fully understood. However, the initial research findings are promising and suggest that napping may be a simple and effective way to support brain health.

Napping and Increased Brain Volume: How to Get Started
If you’re looking to take advantage of the potential brain-boosting benefits of napping, here are some helpful suggestions:
- Aim for naps lasting 20-30 minutes to avoid grogginess and interference with nighttime sleep.
- The ideal time for a nap is typically early to mid-afternoon, when most people experience a natural dip in energy levels.
- Find a quiet, dark, and comfortable space to nap. Use earplugs or an eye mask if needed.
- Establish a routine by napping at the same time each day.
- If you’re feeling tired and in need of a nap, don’t ignore it, because your body is likely signaling that a short break could be beneficial.

The emerging research linking naps and brain volume is both exciting and promising. While further studies are needed to fully understand the mechanisms at play in this relationship, the idea that a short nap can potentially contribute to better brain health is a compelling reason to embrace the age-old tradition of siestas.
The next time you find yourself craving a nap, know that you might be doing more than just recharging your energy–you could be giving your brain a helpful nudge as well.
