Tired
I have sick in my skin. Just look at it, it doesn't look too good. Whenever I have sickness in my skin, I know that I'm probably tired.
Imagine yourself being really, really tired. Then look at your skin. It's all blotchy and sickly looking.

Why so tired? Your body is heated (ひ) up from exercising way too much. You should let that heat cool down so your skin starts looking better.
Feel all the heat (ひ) emanating from your body. It makes you realize how very, very tired you are.
