The Psychology of People Who Stay Up Late On Purpose

People who stay up late on purpose aren't lazy. And most of them aren't really choosing the night at all. Researchers call it your chronotype, which just means the time your body thinks it is.

You'll know which one you're paying for, and the one small thing that actually moves the clock. If your sleep timing is hurting your work, your studies or your health most days, that's worth talking to a doctor about. If this made sense, tell us in the comments which one is yours.
