Fat Metabolism Holds the Key to Why We Need Sleep

8 minutes

Sleep is not just downtime but a built-in survival mechanism that protects your brain from toxic byproducts created when mitochondria leak electrons
New research shows that the more electrons your cells fail to use, the greater the buildup of reactive oxygen species, which directly triggers your need for sleep
Excessive fat burning under stress makes this problem worse by clogging energy pathways, depleting cofactors, and pushing your body into deep fatigue
Serotonin levels rise when fatty acids flood your system, creating another pathway that drives drowsiness and heavy sleep pressure
Supporting your mitochondria with healthy carbs, avoiding extreme cardio, and limiting harmful fats found in seed oils lowers electron leaks, reduces sleep demand, and helps you feel more energized
