Science confirms what we night owls have always known:
A couple of weeks ago, I reported on the science of chronobiology, which finds we all have an internal clock that keeps us on a consistent sleep and wake cycle. But the key finding is that everyone’s clock is not the same. Most people fall in the middle, preferring to sleep around 11 pm to 7 am. But many — perhaps 40 percent of the population — don’t naturally fit in this schedule.
There are night owls among us — whose whole circadian schedules are shifted later — and morning larks, who are shifted earlier. (If you’re curious, you can assess your chronotype with this quiz here.) These traits are determined by genetics and are extremely hard to change. What’s more, the research is finding that if we fight our chronotypes, our health may suffer.
But most striking to me wasn’t the health implications of messing with your clock. It was the stigma late sleepers feel in a society ruled by early risers. Simply put: These late sleepers are tired of being judged for a behavior they cannot easily control. If they can’t change their sleep patterns, maybe society should become more accepting of them.
