Something I noticed in my falling asleep pattern (and did not found in the article yet) is the relation with the air I breathe. It's very easy for me to fall asleep somewhere in the middle of green forest and the other way around - I noticed that I sleep badly in a medium that for some reasons had insufficient aeration. Is it possible for the loss of sleep across the century to have something to do with the quality of our air?
