1. There are so many things to think about, how can you just turn your brain off? Perceptive people notice everything and we’re good at making connections between all the different kinds of knowledge we collect. At the end of the day, this means the sheer volume of stuff we’re processing has a lot of momentum. It’s hard to slow down and stop the wheels from turning long enough to fall asleep.
2. Which means that falling asleep is more difficult. An overactive brain doesn’t know what ‘bedtime’ means.
3. Perceptive people tend to be more intelligent, which means they are likely night owls. If we followed our simple human tendencies, we’d sleep and rise with the sun. Going against the grain by staying up and sleeping late is a mark of intelligence, at least one study shows.
4. Perceptive people also tend to be creative. Creative people do their best work at night. Staying up late isn’t a common trait in adulthood, so in breaking convention, you’re already wiring your brain to do new things.
5. We are filled with ideas, so we want to make the most of our time. For really perceptive people, our day jobs aren’t that fulfilling. When we get home at the end of the day, we finally have time to think about and work on all of the projects that are actually interesting to us. This can cut into our sleep time or make us have irregular schedules, which means sleep is harder once you are in bed.
6. All that thinking has given us better brain stamina. There’s a set number of hours people have after they wake up before they start to feel groggy again. For some people this time frame is incredibly short, and they need naps. For people people, its about 16 hours, depending on how long they slept for. For troubled sleepers, this time frame extends even farther.
7. At the end of the day, when we’re along with our thoughts, there’s still so much to go through. We’re thinking all day long, but it’s more reactionary than contemplative. Alone in our beds, we can finally reassess the day and analyze details to our heart’s content.
8. Compared to being awake, sleep just seems so boring. There’s a lot you can do about inability to sleep: get on a schedule, stop using screens before bed, drink tea and try to just relax. But when your mind is full of fun, interesting thoughts — who wants to do that?
