Many biological processes happen during sleep: The brain stores new information and gets rid of toxic waste Nerve cells communicate and reorganize, which supports healthy brain function The body repairs cells, restores energy, and releases molecules like hormones and proteins
Are you dead when sleeping?
Scientists used to think that people were physically and mentally inactive during sleep But now they know that’s not the case All night long, your body and brain do quite a bit of work that’s key for your health

Does sleep prune unused connections in the brain?

What is the connection between deep sleep and effective brain function?
The study, out Wednesday 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

Why is the brain active during sleep?
It is believed that dreaming occurs for at least 2 hours each night during REM sleep and that this activity plays an important role in the processing of information and the creation of memory During this stage of sleep, heart rate and blood pressure increase and the activity of the brain is markedly more dynamic
Where does brain waste go?
A waste disposal system in our brains By performing imaging experiments in the brains of mice, they visualized cerebrospinal fluid entering and flowing throughout the brain, eventually draining into the same ducts used by the lymphatic system in the rest of the body
Can the brain clean itself?
While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer’s, researchers say Nedergaard and a team of scientists discovered the cleaning process while studying the brains of sleeping mice Oct 17, 2013
