| For the readers, I'll add a gently remainder that this is about Canada whose southern border is located at about 50°N. That means that the shift in daylight that they experience during the year is quite amplified. Beside that, the article is quite poorly written and misleading! Do not assume that everything said apply for the rest of the world. > Changing our clocks twice a year has little benefit, economic or otherwise, so isn’t it time to stop this antiquated practice? Yeah, thanks for such a scientific sentence with no explanations, no data, not even an introduction to the topic. Next time maybe also ask some astronomers… > As experts on biological rhythms, we support the switch to a permanent time. That's perfectly fine, but at least explain why… and provide advice for the current practice (e.g. for the Spring change, move up your daily routine/schedule by 3 minutes every day for the 20 days before the change, so it will occur smoothly). > People on the western edge are forced to get up an hour earlier than people on the east, according to sun time. What ?! Not in standard time-zones. That can happen only in countries which span across different time zones and decides to keep a single "official" time. > Analysis of health data from millions of people shows that […] No source at all; that seems more a supposition from a USA article. They see sunrise/sunset 19 minutes early (depends on the latitude), but that doesn't mean that they sleep less. All the rest is just bullshit. > Permanent DST would make sunrise even later for everyone, while permanent ST would make sunrise closer to body time. In the northern emisphere permanent DST would make sunrise later in the Winter; permanent ST would keep the sunrise to the current optimum (for the Winter; during the Summer we already wake up with the Sun). |
