Same here, but it's 15 minutes via bike. So I can't really do anything during my "commute." Which means if it snows/flat tire I'm walking the 35min home which is an even bigger time sink.
As others have pointed out, you can utilize that time to:
A) not concern yourself with work and jam out or decompress
B) do work in some capacity, whether that be listenin to lectures or reciting study material from memory
Ultimately this is a negative aspect of commuting that most people don't realize. Sure you save money on housing and food, but you still have to pay for transportation, have to live (most likely) with family or roomates to save money, and have to commute - which usually means it's more difficult to find volunteering opportunities.
