I was reading the article but I found little consideration that light at night isn’t necessarily the cause of heart changes but the same habits that would be indicative of light at night; long periods of sitting, lack of mobility, stimulant use, etc could be other possible explanations for heart changes.

Anyone informed on this topic that can speak more about that? I find it extremely hard to believe that standby lights in a dark room are going to have a meaningful impact on my heart structure as the article states.
