Summary

Sleeping 10-12 hours nightly linked to premature death.
Excessive sleep may signal early dementia stages.
Consistent sleep schedules promote longevity more than hours.

Sleeping for more than eight-and-a-half hours nightly can lead to serious health consequences, including a potentially earlier death. Studies indicate that individuals sleeping 10 to 12 hours per night face increased risks of metabolic diseases and may exhibit early signs of dementia.

The Framingham Heart Study observed a correlation between longer sleep durations and the initial stages of dementia. Researchers are exploring whether oversleeping causes health issues or is a symptom of poor sleep quality.

Experts emphasize that sleep regularity is as vital as duration for longevity. Consistent sleep patterns are more strongly associated with a longer life than the total number of hours spent in bed. Nighttime sleep is irreplaceable by daytime naps.
