Rome’s LED Streetlights

The naysayers are correct about the LED lights in Rome: The old lights are unambiguously better — for the residents’ health if nothing else. There is significant research showing that blue-spectrum light at night interferes with the body’s circadian rhythm and can affect sleep patterns. Indeed, the Canadian Olympic rowing team used blue-light blocking sunglasses for better sleep at the Games in Rio, while the Dutch swim team used exposure to intense blue light before nighttime races to improve performance.
