When we don't get enough sleep, the brain begins a process where its cells—astrocytes and microglia—start breaking down connections and debris within the brain. This process, in itself, isn't necessarily negative: in the short term, it helps clean up damaged or worn-out parts.
But if sleep deprivation continues for a long time, this process can become detrimental. The brain begins to break down healthy connections and irreversibly damage itself, affecting memory, concentration, and other vital functions.
So, even though the brain tries to help itself, chronic sleep deprivation can lead to self-harm. Get some sleep and your brain will thank you for it!
