Good answers! I agree about the verb "arise" being uncommon in normal speech.
May I just add that for many people there is a big difference between "to wake up" (stop sleeping) and "to get up" (arise, rise up from the bed)? When I wake up in the morning, I always lie there in bed for a while (until I really, really start to want my coffee) and only then do I "get up"!
In my part of the world, people say that they "get right up" if they get out of bed as soon as they wake up. My husband always gets right up! I never get right up. :)
