The eternal debate between night owls and early birds has long been a topic of interest, with proponents on both sides claiming superiority. But what does science say? According to researchers, our internal biological clock, or circadian rhythm, controls numerous physiological outputs, including alertness levels, sleep, hormone levels, and blood pressure.
Your "chronotype" is your circadian preference - whether you're a morning lark or night owl. The reality is that our chronotype naturally shifts as we age, with teenagers having a later chronotype and adults drifting earlier. But what about the claim that night owls are more intelligent and creative? While there's some evidence to suggest this, it's not without its limitations.
A 2007 study found evening-disposition was correlated with divergent thinking strategies - in other words, more creativity. However, a 2024 paper from Imperial College London found those who stay up late had "superior cognitive function" compared to morning larks. But experts caution against making definitive links between chronotype and traits like intelligence or sociability.
The truth is that our individual sleep patterns are influenced by a complex array of factors, including genetics, lifestyle, and environment. While you can't fundamentally change your chronotype, you can work in harmony with it. This means understanding which type you are - not always easy, as our habits and routines often mask our natural tendencies.
One way to determine your chronotype is through saliva tests measuring melatonin levels throughout the day. Or, simply try sleeping without an alarm for a week, avoiding depressants and stimulants, and let your body find its natural rhythm. If you're a night owl, but have to get up early, can you tweak your biological clock? It's possible to shift modestly, but only with structured routines such as morning light, fixed mealtimes, earlier exercise, and caffeine cutoff.
The key takeaway is that our chronotype plays a significant role in our daily lives - from work performance to mental health. Rather than trying to force a routine at odds with your biological clock, it's better to operate in tune with it. After all, as the saying goes, "the second mouse gets the cheese."
