Could We Evolve to Never Need Sleep?

What would it take for humans to live without sleep? This exploration breaks down the biological systems that sleep supports, what engineering solutions could replace them, and the costs involved. It covers brain reset mechanisms, toxic waste clearance, energy demands, and a comparison with animals that naturally sleep with half their brains at a time.

■ Brain Reset System
- How neurons create a slow rhythm during sleep to reduce noise and preserve learning
- A proposed approach using implanted electrodes to run the reset cycle while awake

■ Brain Waste Clearance
- Why protein byproducts that build up during the day need sleep to be flushed out
- A concept where each half of the brain takes turns being cleaned

■ Energy Cost and Biological Trade-offs
- The increase in energy demand if the brain runs 24/7
- Comparison with the bottlenose dolphin's ability to sleep one brain hemisphere at a time
- A wearable sleep suit concept as a potential packaging of these solutions

This is suited for viewers curious about neuroscience, sleep science, and biohacking concepts. Watching provides a clear picture of what sleep actually does for the brain and the practical limits of replacing it with technology.
