[00:00:00]Before we start, if this changes how you see your body, follow Bone Wise, drop a like, and leave a comment below. One in three Americans and one in three Brits are chronically sleep deprived. Here's what that is doing to your brain. While you sleep, your brain runs a cleaning cycle. It flushes out toxic waste proteins that build up during the day.

[00:00:20]Skip sleep [music] and those toxins stay, building up night after night.

[00:00:25]Without sleep, your brain cells physically shrink. The connections between them break down. This is not metaphor. Your brain is literally eating itself, a process called autophagy. Your amygdala, your brain's fear and emotion center, becomes 60% more reactive. Your rational brain goes offline. You become emotionally explosive, anxious, irritable, irrational. Your hippocampus, where memories are made, cannot consolidate information without sleep.

[00:00:51]Everything you learned that day, every conversation, every experience, [music] gone because your brain never filed it.

[00:00:58]One night of poor sleep reduces your natural killer cells, your immune defenders, by 70%. Your body becomes completely open to infection, illness, and disease. Your cortisol, the stress hormone, spikes 37%. Your body enters a permanent state of low-grade emergency.

[00:01:14]This is what chronic sleep deprivation does. It doesn't just make you tired. It dismantles your brain piece by piece.

[00:01:21]But your brain can recover with 7 to 9 hours every single night. Follow Bone Wise and see exactly what your habits are doing inside you.
