Four ways that falling back from Daylight Saving Time can kill you

We go through this ridiculous change for no good reason at all, yet it is unhealthy and dangerous. For years I have been railing on about why we still have Railway Time, our time zone system developed for the convenience of those who wrote train schedules and then TV guides. Twice a year I complain about War Time, the Daylight Saving Time developed in the First World War to save coal and keep people working in the factories longer. Except the war is over and we now have air conditioning and artificial lighting, so it doesn't actually save any energy at all. And now, there is a lot of evidence that these time changes are really bad for your health. The fall back switch, where we get an extra hour of sleep, is far less disruptive than the spring forward, but it still is problematic. It can worsen depression. A Danish study examined 185,419 diagnoses of depression between 1995 and 2012, expecting to find increasing depression rates as days got shorter. But they were surprised by the huge spike right after the time change. The researchers controlled for variables like day length and weather, which they say confirms that the 8 percent rise in depression diagnoses was not a coincidence. And while their study focused on people with severe depression, the authors say the time shift likely affects “the entire spectrum of severity." The authors of the study question whether it is more useful to have extra daylight in the evening rather than in the morning. The study author points out that "We probably benefit less from the daylight in the morning between seven and eight, because many of us are either in the shower, eating breakfast or sitting in a car or bus on the way to work or school. When we get home and have spare time in the afternoon, it is already dark."
