Global Shift Away From Daylight Saving Time Gains Momentum

OPA WIRE, Oct 25 (OPA) — Britain transitioned to Greenwich Mean Time at 2:00 a.m. today, ending the British Summer Time period. While the UK continues the biannual adjustment, it remains part of a shrinking minority of nations that still observe Daylight Saving Time (DST). Approximately 139 countries now maintain a single time zone year-round, with roughly one-third of the world’s nations still shifting clocks.

Over the past decade, several countries have formally abolished the practice, including Azerbaijan, Iran, Jordan, Namibia, Russia, Syria, Turkey, and most of Mexico. Regional exceptions persist, such as in the United States, where Hawaii and most of Arizona do not observe DST. Australia also maintains a fragmented approach, with Queensland, the Northern Territory, and Western Australia opting out of the seasonal change.

Research into the physiological impacts of time shifting has intensified, with health experts highlighting potential risks. Professor Jagdish Khubchandani of New Mexico State University noted that the transition can induce a state similar to 'mini jet-lag.' Studies have linked the clock change to temporary spikes in heart attacks, strokes, and blood pressure fluctuations, alongside increased reports of depression and mood instability.

Beyond physical health, data suggests broader societal consequences. Research from Sweden indicated a 10 percent increase in psychoactive substance use following time changes, while other studies have observed a six percent rise in fatal traffic accidents after the spring transition. As evidence of these disruptions grows, calls for the permanent abolition of DST are gaining traction among scientists and policymakers globally.
