Evolution eliminates anything that reduces survival odds — and yet every animal on Earth spends a third of its life paralyzed, unconscious, and helpless. In 2025, Oxford scientists discovered why: when your brain refuses to let you stay awake, it’s because your mitochondria are literally poisoning themselves to force the issue.

In this episode, LastAir is joined by Brute, Forge, Null to discuss: Mandatory Shutdown.

Key Numbers

• ~60%: expansion in brain interstitial space during sleep vs. wakefulness, driving glymphatic flow (Xie et al. 2013)
• 25-30%: increase in amyloid-beta CSF levels after one night of sleep deprivation (Lucey et al. 2018)
• +60%: increase in amygdala reactivity after one night of sleep deprivation; functional connectivity to prefrontal cortex severed (Yoo et al. 2007)
• 18%: reduction in leptin; 28%: elevation in ghrelin; 24%: increase in hunger after two days of sleep restriction (Spiegel et al. 2004)
• RR 1.27 (short sleep) and RR 1.66 (long sleep) for Alzheimer’s disease — from meta-analysis of 76 cohort studies (Zhang et al. 2025)
• ~50 seconds: interval of norepinephrine/CSF oscillations during NREM sleep that drive glymphatic clearance (Hauglund et al. 2025)
• 2 hours (African elephant) vs. 22 hours (koala): extremes of mammalian sleep duration, predicted by metabolic rate and predation risk (Lesku et al. 2006)
