Quality sleep is the single most powerful biological lever for cognitive performance, hormonal equilibrium, cellular repair, and cardiovascular health. Yet modern lifestyle factors—such as artificial blue light exposure, irregular eating windows, and chronic low-grade stress—severely fragment natural sleep architecture.
