New UCLA Research Reveals Why Sleeping is So Important – NBC Southern California

The study, released in the journal Science Advances, noted that the sharp shift in sleep function is “exceptional considered that this shift likely signals a profound shift in the function of sleep and the behavior of sleep procedures.”

The research study was co-authored by Junyu Cao, who conducted research in Savages lab and is now an assistant teacher at the University of Texas at Austin; Alexander Herman, an assistant professor of psychiatry at the University of Minnesota, Twin Cities; and Geoffrey West, a physicist who is the Shannan Distinguished Professor at the Santa Fe Institute.

A dramatic change in the purpose of sleep occurs when kids are about 2 1/2 years of ages– a time when sleeps primary function changes from brain-building to brain repair and maintenance, according to a study launched Friday by scientists at UCLA.

Poe noted that a persistent lack of sleep likely adds to long-lasting health issues such as dementia and other cognitive conditions, and advised people to go to bed when they begin to feel exhausted.

Researchers, who used information from more than 60 sleep studies including humans and other mammals, discovered that all types experienced a significant decrease in REM sleep when they reached the human developmental equivalent of about 2 1/2 years of age.

Babies spend about 50% of their bedtime in REM sleep, with that number being up to about 25% by the age of 10 and continuing to reduce with age. Grownups who are older than 50 invest about 15% of their time asleep in REM, according to scientists.

” Sleep is as crucial as food,” Poe stated. “And its amazing how well sleep matches the requirements of our nervous system. While we sleep, our brains are not resting.”

The transition at about age 2 1/2 represents changes in brain development, according to researchers, who state that sleep then assists fix a specific amount of neurological damage suffered during waking hours, and essentially declutter the brain.

” Sleep is as important as food,” Poe said. While we sleep, our brains are not resting.”

Almost all of the brain repair occurs throughout sleep, according to the studys senior author, Van Savage, a UCLA teacher of ecology and evolutionary biology and of computational medicine.

” I was shocked how huge a change this is over a short duration of time, which this switch happens when were so young,” Savage said. “Its a transition that is comparable to when water adheres ice.”

The National Science Foundation and the Eugene and Clare Thaw Charitable Trust helped to money the study.

” Dont wake children up throughout REM (quick eye movement) sleep. Important work is being done in their brains as they sleep,” stated Gina Poe, the senior research study author and a UCLA teacher of integrative biology and physiology who has conducted sleep research for more than three years.
