Actually they found higher sleep quality in some groups.
The article also doesn’t mention how long the study was and only looked at 18-24 years old.
The main issue with light exposure are long term effects, such as increased rush of hormone-depebdant cancers.
We don’t have a lot of long term study, but we know melatonin production is affected.
For the record, I did my PhD on light pollution, and while not a health expert, I have assisted to multiple talks at scientific conferences on the subject.

Can you talk more about melatonin, hormone dependent cancers, and light exposure? Also, what about shift work and rotating schedules?
