Chile implements daylight saving time, aligning clocks with Argentina
Chile has transitioned to daylight saving time, advancing clocks by one hour to maximize natural light. This change aligns Chile's time zone with Argentina, eliminating the previous one-hour difference between the two nations.
The synchronization impacts major international border crossings. The Cardenal Antonio Samoré Pass has adjusted its operating hours to 8:00 to 19:00 daily, while the Cristo Redentor Pass remains under its specific national operational schedules. These changes are expected to facilitate easier travel and commerce for tourists and transport operators between the two countries.
Health experts and psychologists have raised concerns regarding the biological impact of the shift. The sudden change can disrupt circadian rhythms, potentially leading to fatigue, irritability, sleep fragmentation, and reduced cognitive performance, particularly in children, the elderly, and those with existing sleep disorders. Specialists recommend gradual adjustments, maintaining regular sleep schedules, and limiting screen exposure before bed to aid adaptation.

- [○ 1 SOURCE] A review of over 60 studies indicates that the transition can lead to sleep disturbances, difficulties in executive functions, and increased depressive symptoms.
- [○ 1 SOURCE] Pediatric populations, the elderly, and individuals with pre-existing sleep disorders are most affected by the adjustment. radioallen.cl
- [○ 1 SOURCE] Robust evidence links daylight saving time transitions to an increase in heart attacks, workplace accidents, and traffic accidents.
- [○ 1 SOURCE] Advancing the clock can cause daytime sleepiness, fatigue, and reduced physical and cognitive performance. radioallen.cl
- [● 3 SOURCES] The transition to daylight saving time in Chile begins at midnight on Saturday, September 5, 2026. radioallen.cl · g5noticias.cl
- [○ 1 SOURCE] The transition to daylight saving time acts as a circadian stressor, causing a functional mismatch in the biological clock.
