Changing Daylight Saving Time Might Reduce Obesity
I knew it was because of Daylight Saving Time that I’m overweight! I just knew it! Okay, perhaps that’s a slight embellishment. My slightly-more-than-ideal weight might be partly due to what I eat and how much (or not much) I exercise. But according to a new study at Stanford University, if our government gets rid of Daylight Saving Time, it could provide incredible health benefits:
The researchers estimate that permanent standard time would prevent about 300,000 cases of stroke per year and reduce the number of people with obesity by 2.6 million, compared to biannual changes. Permanent daylight saving time would also be positive, although with a smaller impact.
So it’s the changing of time that matters, and to some degree, having more daylight. So apparently even if the government never changes the system officially, one could just ignore the time change and be less fat. Works for me! I could switch my sleep habits an hour if that helps me be less overweight. That would surely be easier than eating healthy and exercising more! 🙂
So far I’m having fun with this. However, it is an actual scientific study, and they used mathematical models to simulate this, trying to find the impact of time policies on light exposure and circadian rhythm (your body’s internal clock). But I’m skeptical. Normally I’m all for the use of math and the scientific method, but I think those numerical claims are vastly exaggerated. There might be a real benefit — I’m not arguing that — but preventing 2,600,000 cases of obesity? Whatever.
If we’re not going to change Daylight Saving Time, I’ve got some ideas to improve it, which I’ve discussed before: a better way to fix Daylight Savings Time. Most people would be for one of those plans, I think, but so far it has been ignored.
As far as reducing obesity in America (which is a big problem), I wish changing the clock would be a solution. But I think the best solution is still eating less and exercising more. That strategy is no secret, but perhaps we need a fresh approach to promoting it… (I have an idea, which will be in a future post.)


6 National Frozen Food Day — This would be a good day for lasagna. Mmm… Of course, there are other options, like Hot Pockets, and there are some frozen desserts that are pretty good.
