Back in OIF I & II this may have been the case. But for most people over there now it's sustainment, so when you have your day or two off a week you actually do have some free time to do things like this. And it's getting that way for OEF also.
I was in OIF 3 & 4 and during 4 we had more time to do these things during our off hours. It does help to greatly improve morale which directly improves your work ethic. Less people getting depressed about not talking to people at home is less visits to the med shack, which is less medication, which is happier soldiers when they go home and continue their life.
