Circadian rhythms are internal biological clocks that regulate sleep, metabolism, and hormone production, aligning our bodies with the 24-hour day-night cycle. Groundbreaking research on these rhythms, recognized by the 2017 Nobel Prize in Physiology or Medicine, revealed the molecular mechanisms controlling this essential process. Disruptions—caused by shift work, irregular sleep, or excessive light exposure—profoundly affect…
