A 2021–2023 study in Spain of 1,899 people found night shift work increases long COVID risk by 88%.

Night shifts didn’t increase infection risk, suggesting disrupted circadian rhythms may affect how the body recovers from infection.

The first piece I wrote about #ArtificialLight #ALAN #LightPollution #Darkness #Night was this one, "The Trouble with Darkness" (2017), which riffs off Cronon's famous Trouble with Wilderness to critically examine satellite imagery of light at night.

Has your observing site grown brighter—or darker?

Our 2025 light-pollution layer is live, based on the complete annual NOAA VIIRS dataset. Compare 2012–2025 for long-term change.

2025 is the latest completed annual layer; 2026 is an estimate.

I've been studying #ArtificialLight #lightpollution long enough now (!) that it's fasc to see how quickly activists, scientists & others mobilizing #lightpollution (among other reasons) to critique data centers.
That argument likely wouldn't be persuasive wo research over previous 2 decades.
