eli5 why just one single day sleeping at the wrong time is enough for destroying your sleep routine, and makes it so hard to restore it?
It could depend on age and how much exercise you get. Younger folks who exercise can sleep late one night and be fine the next. A 40 year old who hasn’t worked out in a decade will have trouble readjusting.
What’s a sleep routine?!
I think this is probably just down to the individual. Personally my sleep patterns are pretty flexible.
A couple of nights ago I met up with some friends and we drank some wine, talked nonsense till the early hours of the morning and I ended up sleeping on a sofa. This is pretty unusual for me, especially on a week night, and i was a bit groggy the next morning but I just went to bed a bit earlier the next night and was back on track.
I’d imagine that all kinds of things will influence your sleep though – diet, fitness, age, stress levels. Not to mention immediate stuff like whether you have a full belly, a full bladder, a blocked nose.

What are you talking about? Feeling groggy due to bad or short duration sleeping in the morning does not mean you will sleep worse the next night.
