Recent research on older adults suggests that excessive daytime napping might be an early indicator of Alzheimer’s disease, particularly when it occurs concurrently with other warning signs like memory loss. Many individuals routinely enjoy afternoon naps. Short naps can refresh one's energy and enhance productivity, but napping for extended periods often results in feeling lethargic and more tired than before
While there remains ongoing debate regarding the ideal nap length for health benefits, numerous studies advocate for keeping naps under 30 minutes to optimize their positive effects and avoid the drawbacks of longer sleep periods. The research found that longer naps were connected to cognitive deterioration in elderly men, while naps under 30 minutes did not increase the risk of cognitive issues.
The 14-year study involving 1,401 participants revealed that while all adults tended to nap more as they aged, those with progressing Alzheimer’s disease experienced a doubling in both the length and frequency of their daytime naps. While napping by itself is not a direct cause of Alzheimer’s, excessive napping could be a risk factor, potentially increasing the likelihood of developing the condition without necessarily confirming it will occur.
In line with earlier research, it was found that extended naps negatively impacted cognitive function, though the exact cause is unknown. Furthermore, such cognitive decline is frequently seen as a precursor to Alzheimer’s disease.
Daytime sleep patterns in older adults are often overlooked, and there is a lack of consensus on the management of napping in clinical practice. The study’s findings suggest that frequent daytime napping could indicate a higher risk of Alzheimer’s dementia. Additionally, an increase in napping duration each year may signal worsening or more severe progression of the disease.
The study revealed that both the length and frequency of naps increased with age, and there was a reciprocal, long-term link between daytime sleep and Alzheimer's. Researchers aim to highlight the significance of monitoring changes in daytime sleep habits, as these alterations are crucial for understanding shifts in brain function related to circadian rhythms, cognitive decline, and dementia risk.

Daytime napping and Alzheimer's dementia: A potential bidirectional relationship
As we grow older, our brains undergo various changes that lead to cognitive decline. The acetylcholine-dependent neurotransmitter system slows with age, primarily causing older adults to struggle with concentration and working memory. It also contributes significantly to neurodegenerative diseases like Alzheimer's.
Sugar sweetened drinks have faced criticism for years, with diet versions often viewed as safer. A new study ties both sugar-filled and artificially sweetened drinks to elevated chances of metabolic dysfunction-associated steatotic liver disease (MASLD), the severe liver disorder previously named nonalcoholic fatty liver disease. This occurs when fat accumulates in the livers of individuals who rarely or never drink alcohol.
Regular exercise keeps your body and brain sharp as you age. It preserves mobility, supports independence, and may slow cognitive decline. New research shows exercise reprograms the body at the molecular level, fundamentally transforming biological systems from the inside out.
