Nap or sleepiness against one's will? Scientists examined the link to dementia

A study from Johns Hopkins Bloomberg School of Public Health found that frequent napping is linked to a 48% higher risk of dementia. The research analyzed data from 995 participants aged 65 and older, revealing that those who napped daily had a significantly higher incidence of dementia compared to those who rarely napped. Notably, unplanned naps were associated with a 39% increased risk, while planned naps showed no significant correlation. The study suggests that excessive daytime sleepiness may indicate underlying health issues, including sleep disorders or neurodegenerative diseases. However, the relationship between napping and dementia remains complex, with further research needed to clarify causation.
