Why you’re not a morning person (unless you are)

Woman sleeping, not a morning person
As it happens, I am a morning person. Our son definitely is. My wife isn’t a morning person at all and we’re not sure whether our daughter is, yet.

Whether you are a morning person or not, it apparently has a lot to do with genetics. Brian Resnick delves into why this is the case on Vox in his article titled “Late sleepers are tired of being discriminated against. And science has their back”.

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.

It turns out that this is also very much a cultural issue with the expectation being that people who are not morning people are somehow slackers. I didn’t think about it in those terms, probably because I tend to function better in the mornings (at least, once I’ve taken my meds).

Watch this Vox video titled “Late sleeper? Blame your genes” that accompanies Resnick’s article, perhaps with coffee while you wake up.

On a related note, it also turns out that so-called “coffee naps” are great ways to recharge during the day. I tend to nap for around 20 minutes and will do that if I have an opportunity because it works well for me.

Apparently, a cup of coffee right before a 20 minute nap could be just the thing you need to recharge and return to a much more productive state. According to Vox:

It’s counterintuitive, but scientists agree that drinking coffee before napping will give you a stronger boost of energy than either coffee or napping alone. To understand a coffee nap, you have to understand how caffeine affects you. After it’s absorbed through your small intestine and passes into your bloodstream, it crosses into your brain. There, it fits into receptors that are normally filled by a similarly shaped molecule called adenosine. Adenosine is a byproduct of brain activity, and when it accumulates at high enough levels, it plugs into these receptors and makes you feel tired. But with the caffeine blocking the receptors, it’s unable to do so. Here’s the trick of the coffee nap: sleeping naturally clears adenosine from the brain. So if you nap for those 20 minutes, you’ll reduce your levels of adenosine just in time for the caffeine to kick in. The caffeine will have less adenosine to compete with, and will thereby be even more effective in making you alert.

So, if you’re ever accused of being lazy or slacking off because you’re not a morning person or because you just want to have a quick nap and recharge, there is a body of science backing you up!

  1. My sleep routine is super weird at the moment. I’m currently getting to bed anytime between 03:30 and 07:30 and waking up sometime between 12:00 and 14:00.

    Breaking the routine and becoming more diurnal is quite challenging.

What do you think?
