It depends on your chronotype. It messes with PM people much more than AM people.
If you’re tired in the evenings and wide awake in the morning, then going to bed slightly earlier and getting up earlier is easy.
If you’re alert in the evenings and tired in the mornings, going to bed early is counter-productive, you just lie there awake getting less tired. Similarly getting up earlier is even harder than normal.
If you’re an AM person, then you’ve drawn the lucky straw - the world is built for people like you. But there’s lots of PM people who struggle daily, fighting against their body clocks just to show up to school/work on time.



AM = morning, PM = afternoon/evening/night
Like 7AM or 7PM
AM people are most awake and productive during the morning hours, and get more tired as the day goes on.
PM people are tired in the morning and more alert later in the day/night.
