One of the traits/habits I’ve been fortunate to have/cultivate is daily afternoon napping. I can rest my head and fall asleep in minutes and then wake back up 15 minutes later feeling cognitively refreshed. I’ve done this since my teenage years and throughout adulthood.

Short, intentional, regular napping is associated with a lower risks of dementia. This is different from increased, longer, napping seen in older adults. Longer naps in older adults is associated with Alzheimer’s. See this summary:

It will be interesting to see if further research in humans can pinpoint a plausible causal mechanism in adult for both regular night time sleep and intentional short daytime napping. This might encourage companies to put in ‘sleep pods’ or at least remove the stigma of adult napping.
