If someone's doing something bad or that will have a really bad influence on me, say, a brother just opens the windows wide on a windy winter day while I'm having a fever, and I want him to explain himself. Instead of asking,

What the hell are you doing?

Is it natural to ask,

What do you think you are doing?

    It's perfectly natural (or even "What the hell do you think you are doing?"). You can use it to someone misbehaving, whether or not it affects you personally. Commented Nov 15, 2022 at 12:17

Sure. Bernadette said it to Sheldon and Amy in The Big Bang Theory s12.

Bernadette: What do you think you're doing?

Amy: I thought it was clear. I'm being unnecessarily hurtful but with a sweet voice.

Sheldon: And I don't understand what's going on because I went to MIT.
