Story summary

A University of Oxford study identifies electrical stress in brain cell mitochondria as a trigger for sleep.
Overloaded mitochondria leak electrons, signaling the need for sleep to prevent cellular damage.
The research connects metabolism, sleep, and lifespan, explaining shorter sleep duration in smaller animals.
These findings contribute to understanding the biological necessity of sleep.
