That's because humans are social animals, not work horses. We didn't evolve to live in office chairs/desks as we do today, so of course there's a physiological impact. When we're kept from our family/friends for 8 hours of course we'll be mentally preoccupied during work checking our phones to cope.
I think that most of humanity checks there phones also at home, during dinner, and even during conversations with family/friends, so I don’t think the separation is the cause of that.
