How to live longer: The amount of sleep you need to avoid dementia and death at a young age.

SLEEP, an essential aspect of existence, is required for optimal function in all living things. While sleep patterns are important for our health, not getting enough of them can have major effects for our cognitive function and lifespan.

Although genes and lifestyle choices may be the most powerful predictors of dementia and premature death, sleep disorders, especially experienced over a long period of time, can have a significant impact on both. Many research have attempted to determine the causal relationship between sleep deprivation, cognitive decline, and premature death, but few have come up with solid findings. However, a group of Harvard Medical School researchers was able to add to our knowledge of these connections.

Sleep patterns early in childhood may contribute to the risk of dementia later in life, according to two studies.

The first study looked at around 2,800 adults aged 65 and up and was undertaken by Harvard Medical School.

Individuals who slept less than five hours per night were twice as likely to develop dementia and twice as likely to die than those who slept six to eight hours per night, according to the research.

These findings were then verified by a European study that looked at data from nearly 8,000 people.

When compared to a normal sleep length of seven hours, data showed that sleeping six hours or less at age 50, 60, and 70 was related with a 30% increase in dementia risk.

The sleep duration of study participants was monitored using an accelerometer, which tracked their sleep patterns based on their body movements.

Smoking, physical activity, body mass index, and medical disorders including diabetes and heart disease were all modified to account for typical influences on sleep patterns and dementia risk.

Individuals with underlying mental diseases such as depression, which is closely connected to sleep problems, were also eliminated.

In contrast, an American research of people who were predisposed to Alzheimer’s disease discovered that getting more sleep reduced their risk of developing the condition.

Notably, getting enough sleep reduced the development of tangle disease in the brain, a material that builds up in Alzheimer’s sufferers’ brains.

However, it’s unclear whether these sleep alterations cause a loss in cognitive performance or are simply early signs.

Inadequate sleep, according to some studies, may raise the chance of amyloid deposition, which is a hallmark of Alzheimer’s disease.
