Standard time transition affects sleep and energy consumption

The transition to standard time occurs on the night between October 24 and 25, when clocks are set back one hour. Experts warn that this shift can cause temporary physiological disruptions, including drowsiness, irritability, difficulty concentrating, and early awakenings. This phenomenon is described by some specialists as a form of ‘mini jet lag’ due to the misalignment with the body's internal circadian rhythm.

Medical professionals suggest managing the transition by maintaining regular sleep and meal schedules, increasing exposure to natural light, and reducing evening stimulants like caffeine and alcohol. For those with existing sleep vulnerabilities, the impact may be more pronounced. Nutritionists also recommend consuming foods rich in beta-carotene, such as pumpkin, to support the body during seasonal changes.

Beyond health, the shift has economic and social implications. Data indicates that the standard time period can lead to higher domestic energy consumption, particularly for laundry and lighting, due to earlier darkness. Meanwhile, advocacy groups like Consumerismo No Profit are using the transition to promote the permanent adoption of daylight saving time to improve evening light availability and social well-being.
