Energy is a biological output

Chronic fatigue isn't solved by coffee. Your energy depends on mitochondrial quality, circadian rhythm, nutrition and sleep. Fix the inputs and the output changes.

Highest-impact energy habits

Morning sunlight — synchronizes cortisol peak with your natural cycle. Correct cortisol timing = sustained energy all day.

Eliminate ultra-processed food — glucose spikes and crashes cause the 2-3 PM "crash".

Zone 2 cardio 150 min/week — builds new mitochondria. More mitochondria = more cellular energy.

Hydration (2L+ water/day) — 2% dehydration reduces cognitive performance by 20%.
