Why do people have different inherent sleeping patterns that they gravitate to (e.g. some humans are morning people, whereas some are very nocturnal)?
In: Biology
A lot of it also probably has to do with humans and our instincts. Keep in mind, humanity spent a *considerably* larger amount of time as hunter-gatherers and nomadic warrior tribals than we have as civilized townspeople.
To put it simply — someone has to sit around the fire, keeping watch and telling folktales while the hunting party sleeps through the night.
However, sleep cycles play a huge part in this too. You can teach your body to get used to any sleeping pattern.
It also has something to do with the amount of oxytocin released in your brain for sleeping at certain times of day. Some people wake early because it’s *rewarding* to be up in time for breakfast, or because their favorite drink is half-off before 8am. Some people stay up late because their day isn’t the same if they don’t catch George Lopez at 3am for some reason.
