Permanent DST Bad. So Says This Interactive Map.

Permanent DST Produces the High Chronic Disease Rate Increases Shown In This Interactive Map

Map Tips: Percentage of dark mornings and increased chronic disease rates at your cursor are expressed in this fashion:

First number = Percentage Dark Mornings.
Second number = Increase in chronic disease rate.
“|” is the separator.

Be sure to move your cursor to your home county.

DST costs and harm are routinely underestimated, quietly absorbed, and rarely mentioned. This needs to change.

As shown here, consistent with what is medically known as the "Western Edge Effect," from east to west within a time zone, chronic disease rates systematically increase as the percentages of dark mornings (DM) increase. DST produces those dark mornings.

Let your cursor hover over the map to see percentages of dark mornings and chronic disease rate increases that tend to occur when you move from east to west within a time zone.

The prevailing focus on the inconvenience of changing clocks twice a year pales by comparison to DST’s colossal adverse impact on Chronic Disease, Income, Mood, Longevity, Education, Business, Depression, Real Estate, Property Crime, Cognition, and More.

The designation “Safe” denotes a circadian healthy region where DM is less than 31% and chronic disease rate increases are decidedly less than -0.5%.

With a variety of techniques, we are able to see that Standard Time delivers improvements in a staggeringly large number of categories.
