The text claims that lack of sleep causes the brain to eat itself.

Infact verdict: Mixed (53/100).

The claim that the brain 'eats itself' due to lack of sleep is metaphorical rather than literal. Evidence from studies on sleep-deprived mice shows that astrocytes, which are responsible for cleaning up brain debris, become overactive and start pruning healthy neural connections. This process is part of the brain's maintenance and is exaggerated in the absence of sleep, potentially leading to neurological issues. However, the phrase 'eating itself' is a dramatic simplification of a complex biological process.

Your brain begins to eat itself when it doesn't get enough sleep.
The claim is based on a study showing that sleep deprivation causes astrocytes to over-prune neural connections, which is a maintenance process that becomes excessive without sleep. This is not literally the brain 'eating itself,' but rather a metaphorical description of the brain's response to lack of sleep. Multiple sources, including the Global Wellness Institute, support this interpretation, but the claim is somewhat misleading due to its dramatic phrasing.
