The Atlantic reports on a town in Germany, Bad Kissingen, that is making strides toward letting residents live according to their natural circadian rhythms.

The goal is to get all of the town’s citizens’ chronotypes in an online database. Right now, individuals have to go to this website and input their own data; the hope is that one day schools and hospitals will take down this information as regularly as someone’s height or weight, making it much easier to determine and work with the town’s needs.

In a hypothetical future world where Bad Kissingen succeeds in letting all of its citizens and visitors live out their chronotypes, the societal benefits would be huge. Chronically tired people often struggle with obesity, immune suppression, and mental illness, so the town’s overall health—both mental and physical—would improve.
