One night without sleep impairs cognitive function to the same degree as being legally drunk, with 24 hours of sleep deprivation producing a blood alcohol level of 0.10% (above the legal limit in all US states). The prefrontal cortex, responsible for decision-making, is the first brain region to be affected, and after 48 hours, individuals experience microsleeps where the brain shuts down for 30 seconds while eyes remain open. Critically, during sleep deprivation, astrocytes (the brain's maintenance cells) begin consuming synapses instead of cleaning them, meaning the brain literally eats its own neural connections. Drowsy driving kills 6,400 people annually in the US, more than drunk driving in some years. The brain rebuilds itself every night, making adequate sleep essential for cognitive health and safety.

24 Hours Without Sleep = Legally Drunk (0.1% BAC) #shorts #viral #fact #viralshorts #sleep #trendingAdded:
One night without a sleep makes you as impaired as being legally drunk, and you can't even tell it. 24 hours without sleep equals a blood alcohol level of 0.1%. That's above the legal limit. Your prefrontal cortex, the part that makes decisions, is the first to go. Your brain literally starts powering down section by section like a city in a blackout. After 48 hours, you start having microsleeps. Your brain shuts down for 30 seconds without you knowing.
[music] Your eyes are open. But here's the part nobody tells you. When you don't sleep, your brain literally eats itself. Astrocytes, the brain's maintenance cells, start consuming synapses instead of cleaning them. Your brain is devouring its own connections.
Drowsy driving kills 6,400 people a year in the US alone. That's more than some years of drunk driving. Your brain [music] rebuilds itself every single night. All you have to do is close your eyes.
