City centers have relatively bad air quality and a high amount of ambient lighting at night, compared to non urbanized areas. The cardiovascular effects of poor air quality is arguably well understood.

My bet is that cardiovascular problems cause light exposure at night.

Sorry for exposing my personal medical data, but... I literally cannot fall asleep without at least some light. So I sleep with lights on. Trying to be like normal people would only make my overall health worse. Is this a medical condition that has a name?

Nyctophobia.

Maybe they're exposed to light at night because they're awake at night more often, possibly shift workers, which we already know is unhealthy. I doubt just having light on is causing the effect.

Preprint not peer reviewed. Also: ”A.J.K.P. and S.W.C. are co-founders and co-directors of Circadian Health Innovations PTY LTD.” Lemme guess, looking for funding.

What can we do about the tendency of research articles to get their big flash of publicity before undergoing peer review?

Earlier quoted context omitted.

Do you have to turn the light on to use the toilet?

I do have to, this is why I bought one of those IKEA smart bulbs and made it dark and blue. If I get up at night, I use my watch for light.

Why blue and not red/orange?

Most studies pull from urban populations and usually contrasting with a rural population is done for a demographic comparison. (Most people also live in cities.) The study was careful to use personal light monitoring, so urban residents who nonetheless find ways to live/sleep in the dark would be included in the study.
