It's rarely 8 hours a day "applying to jobs". This is similar to an employer saying "you should work 40 hours/week". In that 40 hours are lots of varied activity, including breaks and lunch and any other activity that will allow you to succeed.

The idea is that we want to set expectation that people should focus on searching for a job and not, say, go on vacation. The wording here also is far more severe than reality only because we want serious participants.
