Hippocrates (c. 460–370 BCE): Sleep as a Pillar of Health
Ancient medicine treated sleep not as a luxury but as a vital process integral to healing and balance. In a world without modern equipment, the bed was a sanctuary—a place where the body could reset its humors and restore cognitive clarity. Hippocrates’ insistence on routine, rest, and the rhythms of day and night resonates with contemporary sleep science that links circadian biology to behavior, temperature, and environment.
Key theme: grounding sleep in natural cycles and thoughtful living.
