Depends in what you do and how you sleep.
I shower getting out of pool
I had a boss that would wake up hung over from the night before, every morning. He once commented about my wet hair in the morning, and said I should shower at night, like he did. I said it wouldn’t matter, because I’d gone out and run a few miles before work, and I’d have to shower again, anyway. He looked at me like I was insane.
