Sleep May Be Even More Beneficial Than You Thought

Sleep is more complicated than many people initially think. It’s split up into four different stages and brings along different benefits, outside of the obvious ones.

During REM, or rapid-eye-movement, sleep (stage 4) you usually dream, but it is not considered deep sleep. NREM sleep (non-rapid eye-movement), or dreamless sleep, is when your blood pressure and breathing rate drop, muscles relax, brain activity slows down, and when you are relatively still. Around 80% of sleep is NREM, and the deepest state occurs in stage 3, the stage that turns out to be the healthiest and most beneficial in the long run.

Deep, NREM sleep helps cleanse the body of toxic proteins and waste that can cause Alzheimer’s and dementia. Per U.S. News, a recent study found in the journal “Science Advances,” “found that the slow and consistent brain activity experienced during deep, non-REM sleep is ideal for the brain’s glymphatic system, which effectively ‘cleans’ the brain of toxic proteins like beta-amyloid and tau.” And tau is among the proteins that, if there is too much buildup, have been linked to Alzheimer’s and dementia.

“Sleep is critical to the function of the brain’s waste removal system and this study shows that the deeper the sleep the better,” said Maiken Nedergaard, co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center and lead author of the study. “These findings also add to the increasingly clear evidence that quality of sleep or sleep deprivation can predict the onset of Alzheimer’s and dementia.”

The findings further highlight the relationship between lack of sleep and dementia and clearly explains why it’s so prevalent among the elderly because the older you get, the harder it is to get deep sleep.

The study was done using mice and anesthetizing them with different drug cocktails to put them in the biological state most like the one experienced in deep, non-REM sleep ideal for brain cleaning.
