Have you ever wondered why sleep deprivation or late nights make us feel groggy, bleary-eyed, and unable to think?A new study published in the journal Nature Neuroscience has uncovered a surprising truth: It’s not because our brains are “out of battery” or “lazy”! ✅ But because our brains are “cleaning themselves” in the middle of the day! How does it work?

Glymphatic System: Normally, cerebrospinal fluid (CSF) will drain and flush out toxins and other waste products, but only when we are asleep. ​Fallback Plan: When we are sleep deprived, our brain waits until nightfall to recover. It forces this flushing system to work even when we are awake and our eyes are open.The price to pay: While the brain is being flushed, the electrical activity that controls "focus" is suddenly cut off. This is why we feel "numb or numb" because our brain is busy doing housekeeping.Based on brain scans (fMRI), scientists have concluded that the brain is willing to temporarily sacrifice its ability to focus in order to protect brain cells from damage from toxins. ​

Conclusion: If you want your brain to run fast and have full energy, there is only one way: "get enough sleep" so that your brain has time to clean itself according to its natural schedule. If you don't sleep, your brain will steal your bandwidth and wash your car in the middle of the day!
