A sleep scientist/professor named Matt Walker has a podcast about, you guessed it, sleep. He talks about this and how it’s very unfair to people who are biologically programmed to get tired later.

He goes on to describe scientific proof of the effect this has on their sleep and the impact to their health. It’s sad really, but his hope is to raise awareness and acceptance of the night owl’s schedule.

It's not only about being tired enough to fall asleep early. If I stick to a 10pm-6am sleep schedule I feel exhausted during the day, and by early afternoon I'll be falling asleep. It's like being jetlagged permanently; my body simply doesn't want to keep to that schedule. It's not just an "oh, you need to stick to the schedule long enough to adapt and get into a proper routine" situation either - it's something I struggled with for years while I was in school and university, despite getting enough sleep.

It's amazing how much better and more energetic I feel - physically and mentally - now I'm able to keep to a sleep schedule that suits me. Obviously exercising is a good thing, but early/delayed sleep phase syndrome are real things.
