Connection Vexation

A riddle for you, this riddle from me. A connection of actions, of which there are three.

The first happens almost nightly. When I refuse to rest my head. Why do I avoid this like the plague? Is it because I’m practically dead?

Then in the early morning, I rise alongside the sun. What starts off slow and sluggish, obliterates stress into fun!

I must then clean myself, in the early dirty hour. For some reason that little knob requires determined power.

So you’ve read or heard my challenge. And here’s your quizzical quest. What mindset connects these actions? What are they? Venture a guess.
