I quite like the sound of most things in this article, and think I will try to adopt some of the principles to my study and see if they will help. Specifically, I need to get back into fiction, because that really did help when I read lots a few months ago. Also, evening walks sounds like a beautiful way to wind down.
Does anybody else here have other advice on ways to combat burnout during a PhD? I (and every other student) would be most interested to hear.
