Why Night Owls Might Be Smarter—But Early Birds May Live Longer

According to The Guardian’s Arwa Mahdawi, whether you’re a “night owl” or an “early bird” depends on your chronotype — your body’s built-in biological rhythm. While many of us like to believe we can train ourselves to wake up with the sunrise, research suggests our natural sleep tendencies are largely hardwired and shift as we age. Teenagers lean toward staying up late, while older adults naturally rise earlier.

Historically, night owls have been seen as the dreamers and artists. Studies from Imperial College London and others found that those who stay up late often perform better on cognitive tests and may display greater creativity. It might be why so many musicians, writers, and inventors claim inspiration strikes at midnight. Yet scientists warn that these links are far from definitive — intelligence and creativity depend on environment, not just bedtime.

The downside? Being a night owl in a world built for morning people can hurt your health. Northwestern University researchers found that people who stay up late have a 10% higher risk of early death, along with more metabolic and mental-health challenges. Late nights are also tied to habits like drinking alcohol, eating junk food, or scrolling endlessly under blue light — behaviours that can throw off hormones and affect mood.

The best advice, experts say, is to stop fighting your natural rhythm. If you’re an early riser, take advantage of morning light and calm starts. If you’re a night owl, structure your day so you can still get enough rest and maintain good nutrition — maybe with a plant-based dinner before winding down. Trying to completely “flip” your body clock is usually unsustainable.

Whether you’re up with the sunrise or stargazing at midnight, the goal is simple: listen to your body, respect the planet‘s natural cycles, and create healthier routines that work in harmony with both.
