Your Mitochondria Have a Schedule: Why Energy Is a Timing Problem (Not a Fuel Problem)
Most people think circadian rhythm is just “sleep timing.” This Deep Dive flips that model on its head using a plant biology review with a human-relevant message: energy is not just about fuel — energy is about timing. The circadian clock doesn’t simply respond to sunlight; it’s shaped from the inside by metabolic cues from chloroplasts and mitochondria — sugars, redox state, ROS, organic acids, and cellular energy status. The result is a living loop: light tunes metabolism, metabolism tunes the clock, and the clock re-schedules metabolism. The real takeaway: resilience isn’t rigid…
