Burning the midnight oil and creativity

circadian rhythms

Are you a creative person? And if so, do you tend to stay up later than most other people in your household? 

A link between staying up late—"to burn the midnight oil," as the cliché goes—and creativity has been found by researchers testing the behavioral patterns of people characterized by a certain kind of chronotype.

People who prefer to stay up late, or who find they are more energized in the evening, or simply do their best work at night, have been shown to follow a biological rhythm referred to as eveningness (as opposed to their so-called "morning lark" companions, who practice the rhythms of morningness).

There seems to be a difference between both chronotypes when it comes to creativity. Let's take a look at why our resident "night owls"—another cliché—seem to be best suited for late-night living. 

While we're at it, let's consider whether staying up late always points to the presence of circadian rhythm sleep disorders.

What is a night owl?

William Shakespeare used the term "night owl," not literally, but in reference to people who were up late at night, in three different works around the turn of the 16th century.

It seems that some of us were already staying up well past midnight even before Edison invented the light bulb in 1879.

As previously discussed in this blog, the preference for late-night activity and sleeping in was coined eveningness by famous sleep researcher Nathaniel Kleitman in the mid-20th century.

This followed efforts by numerous researchers since the years prior to Edison's world-altering discovery to catalog circadian rhythms into what we now understand as chronotypes. 

It wasn't until 2007 that researchers started to seriously examine certain personality characteristics, like creativity, in conjunction with these chronotypes.

Research on late-night creativity

An Italian landmark study published in 2007 on creativity and eveningness showed a correlation between the "night owl" disposition and an elevated ability to apply "divergent thinking strategies" to visual content and to solve problems using intuition. 

This followed more than 2 decades of research into evening disposition, which found, among other things, that: 

  • late-night chronotypes process external information through parameters that are more subjective and emotional.
  • night owls are more open and drawn to unconventional ideas and novel experiences.
  • those with eveningness traits are more likely to create new and original things.
  • evening types work more independently in their field than do their morning-type companions.
  • dimming the lights may actually improve creative performance, according to data from a study published in the Journal of Environmental Psychology. Why? Darker spaces (say, a home office at night with only one lamp on) lead to a sense of perceived freedom to "think outside the box" and encourage exploratory processing as a problem-solving act. 
  • people who stay up late tend to be individualistic in their thinking, which might lend itself to more creative solutions.
  • problem solving that requires insight has been shown to be more effective during "off" times of the day (in example, late at night). Think of the classic "Aha!" moments that you've had; they usually come when you think your brain is in downtime, which is, more often than not, after hours.  

Creativity = problem solving

This is what creativity is, after all. We may conjure images of painters, authors, poets, or sculptors when we think of creativity, but many other occupations demand regular applications of creative thinking:

  • Doctors and nurses
  • Architects
  • Politicians
  • Engineers
  • Personal assistants

So take heart! You don't have to be the next van Gogh to be creative.  

If you prefer to be "in tune with the moon," do you have a sleep disorder?

It all depends.moon_brain.jpg

If you are sleeping an adequate number of hours every night and don't have problems with insomnia or other sleep disorders... 

...and you aren't impaired by morning routines and schedules imposed upon you, then you're probably a natural night owl. 

Often, eveningness runs in families; if your parents were late nighters and slept in on weekends, it's likely you will be, too. 

However, if you cannot abide the demands of morning schedules you are obligated to (for family, school, or work), and you are losing enough sleep to threaten your health and well being because of it, that is a different story.

DSPS vs DSPD

Delayed sleep phase syndrome (DSPS) describes the situation where your rhythms don't mesh with the time commitments you must keep during the day. Teenagers are most famously delayed in their sleep phasing because of developmental changes that reset their biological rhythms later.

Most of us grow out of it, but there are still adults of all ages who can't fall asleep before 1 am. 

If you are one of them, and you are being to feel the impact of sleep debt as a result, then you are likely suffering from delayed sleep phase disorder (DSPD). This is a real sleep disorder with disastrous consequences that include a mounting sleep debt; it requires treatments that can include blue light therapy and cognitive behavior therapy to force a circadian reset. 

The dark side of life after midnight

Though recent research gives glowing praise for night owls when it comes to creativity, night owls have also been found to have their fair share of shortcomings. They:

  • tend to drink more
  • are more likely to smoke
  • have a propensity for mood disorders
  • are less likely to report they are happy
  • engage in more risky, sensation-seeking behaviors
  • rebel against conformity more often
  • have been found to be less conscientious than their "morning lark" cohorts  

Still, the future looks bright for night owls. The working world is beginning to acknowledge that its workers need sleep, so they are incorporating more flex time and encouragingopen_late_sign.jpg telecommuting and remote offices to accommodate those who don't fit the 9-to-5 mold.

In major urban centers, later lifestyles are already the norm. Coffeehouses, nightclubs, bookstores, and other venues that cater to creatives have long kept their doors open to their late-night clientele.

There's less reason to feel guilty about one's late-night tendencies in the 21st century. Just make sure you get your solid 8 hours of sleep at night. If you aren't, consult a sleep specialist.
