Health impacts of seasonal time changes and sleep disruption

Seasonal time changes and irregular work schedules significantly impact human health by disrupting circadian rhythms. In Chile, the transition to daylight saving time requires adjustments to sleep, diet, and medication routines. Experts recommend maintaining stable sleep schedules, avoiding screens before bed, and managing caffeine intake to mitigate fatigue and irritability.

For those on night shifts, the disruption of the internal biological clock can lead to memory issues, reduced attention, and increased risks of diabetes and hypertension. Specialists suggest using dark rooms, strategic naps, and sunglasses during commutes to help stabilize the body's rhythm.

Regarding medication, most treatments do not require immediate adjustment for a one-hour shift, but patients using drugs with narrow therapeutic margins—such as anticonvulsants, immunosuppressants, or insulin—should maintain strict regularity and avoid self-improvisation. Additionally, aging is a natural factor in sleep degradation, as the brain becomes less efficient at maintaining deep sleep phases and protecting against external stimuli.
