Can't sleep early

A tiny positive for teenagers in the last two years:

In a new study from Switzerland, researchers found Swiss teenagers who were home-schooled during school closures between March and June 2020 in the first wave of the pandemic ended up getting significantly more sleep than before the lockdown, which correlated with other improvements in their wellbeing.

"The students got about 75 minutes more sleep per day during the lockdown," says developmental pediatrics researcher Oskar Jenni from the University of Zurich (UZH).

It was a huge pain to wake up early for school, university, gym or work. It's something that I can't explain but my sleep schedule always reverted to 2 a.m. to 10 a.m. when I didn't have to wake up early. Even two different environments like Arabia and Canada couldn't alter that stubborn biology.

It's funny that I prefer a 10-6 sleep schedule but it is what it is.
