Circadian Rhythm: 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: 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.
