Scrapping biannual time changes in Manitoba has been deemed a positive step, but opting for daylight time over standard time is deemed a wrong choice by a sleep medicine expert, particularly for students. Dr. Michael Mak, a psychiatrist and sleep medicine specialist at the Centre for Addiction and Mental Health in Toronto, expressed concerns about the decision. Mak highlighted that while eliminating time changes is beneficial, sticking to daylight time during the winter months could lead to academic challenges and depression due to the lack of morning sunlight. This prolonged darkness in the mornings could disrupt the body’s circadian rhythm, affecting mood, energy levels, and sleep patterns.
The decision to adopt permanent daylight time in Manitoba was announced by Premier Wab Kinew following a public survey that received overwhelming support to end seasonal time changes. However, Mak and other experts argue that standard time aligns better with natural light cycles, supporting optimal biological functions and overall well-being. The preference for morning light exposure to enhance wakefulness and productivity contrasts with the artificial adjustment of daylight time, which disrupts the body’s internal clock and can have negative health implications.
Furthermore, the impact of dark mornings on students, especially adolescents, is a significant concern, as their developmental needs require adequate sleep and proper light exposure for optimal growth and cognitive function. Experts emphasize the importance of maintaining a consistent wake time and seeking light exposure upon awakening to mitigate the effects of reduced morning sunlight. While some may prefer permanent daylight time for personal reasons, the consensus among sleep experts favors standard time for its alignment with natural circadian rhythms and overall health benefits.
