The biological clock refers to the internal mechanism in our body that regulates various physiological processes, such as sleep-wake cycles, hormone production, and metabolism. It is controlled by a region in the brain called the suprachiasmatic nucleus (SCN).
Circadian rhythms are daily cycles that follow a roughly 24-hour pattern and are controlled by our biological clock. They influence our sleep patterns, alertness levels, and overall physiological functioning.
Jet lag occurs when our biological clock is out of sync with a new time zone. Traveling across different time zones disrupts our sleep-wake cycle temporarily until our body adjusts to the new schedule.
Shift Work Sleep Disorder: This disorder affects individuals who work non-traditional hours or rotating shifts. It occurs when their work schedule conflicts with their natural sleep-wake cycle, leading to difficulties in falling asleep or staying awake during desired times.
