Only partially! They're heavily influenced by the time the sun rises. Your body's internal clock is actually 24 hours 11 minutes long on average. The only reason it doesn't drift hopelessly out of sync is that the sunrise "resets" it each day! (https://news.harvard.edu/gazette/story/1999/07/human-biologi...)

Wasn't that debunked? Just look at what happened to people who slept in a cave for a few days, they came out of it having no idea of how long they were in there, even if they were somehow conditioned by others who guessed their own time. If the body had an internal clock, their estimation would not be off by 17 days out of 40. That's some serious mismatch.

Wasn’t aware of that study, but I do think it’s still pretty widely accepted science we have some internal timekeeping facilities. But if we indeed do not, that speaks even more to the importance of sunrise time in regulating our bodies!

What about countries with short sun lights during the winter, and large sunlight during summer?

What about them? (Sorry, not being coy, I genuinely don't understand where you're going with the question.)

These people's Circadian rhythm get messed, and may not follow the same patterns as those who live in more balanced geographical areas, don't they?

Yes, they do! This is also why we have timezones, they help somewhat even when they can't be perfect.
