CLIn a letter to the editor published on August 31, 2026, two chronobiologists, Luis F. Larrondo and John Ewer, respond to recent comments by Chile’s Minister of Energy regarding the daylight saving time change. The minister described the issue as 'complex' and suggested that children would find it difficult to adjust to the time change, as it would require them to wake up while it is still dark. The scientists argue that biologically, deciding on a consistent schedule is not particularly complex, but repeatedly changing it is what poses challenges for the human body. They emphasize that exposure to morning light aligns with biological rhythms and that the standard time (often mistakenly called winter time) provides more light in the morning, which is recommended by chronobiology. The authors suggest maintaining the standard time year-round to better align with natural circadian rhythms.
Bias read (Center): The article presents scientific perspectives on daylight saving time and does not take a clear ideological stance. It critiques the minister's statement through a scientific lens rather than a political one, offering balanced arguments based on chronobiological research without overtly favoring any側
