I 100% agree. I'm unfortunately not an expert in the field but over the years I've seen "studies" that are very flawed or impossible to replicate. I'm all for some experiments for those willing... perhaps it would overall increase the amount of sleep students get... but for some I feel it would completely wreck their schedules.

This is anecdotal but when I went to live with my grandparents for a summer, I hated every minute of it. They lived on a farm with no wifi. By the last week or two though, I realized I sorta enjoyed it. I was out like a light by 10 pm every day. I was getting more exercise etc. I had no reliable reason to stay up past 10 pm and my body seemed to adjust to what felt natural.

As an adult, I can say that if school started later, I would have just stayed up later. There was even a time in college that I would stay up till 4-5 am. Sometimes you would know a snow day the night before and I would tell my friends on the west coast that I could stay up even later. It was awful but I couldn't see it at the time. It took me years to fix. I now sleep around 1 AM which I still wish I could sleep earlier but I'll take it.
