They restore relaxation, yes, but not attention. To my knowledge the only way to get attention as a loner is to be stared at when you ran into someone while you walk, and that's rather minimal. Otherwise it's constantly calling your friend to hang out and making sure you don't miss the nightly hangouts.
To be fair, getting low attention while being a loner is definitionally expected, but I think there should still be more activities to do though.
