At 5 am, social media is full of proof that early risers have already won the day. Cold baths. Diaries. Sunrise races. Waking up with the chickens can make you more productive — but there’s a catch.
Productivity gurus insist that this is the routine that separates the most successful from everyone else, an idea reinforced by figures known for waking up early, such as Apple CEO, Tim Cookbusinessman and CEO of Virgin Richard Branson and the Hollywood actress Jennifer Aniston.
The message is simple: wake up earlier, earn more. But science tells a more complex story.
For many people, a 5 a.m. routine clashes with their biology and can harm both their health and productivity. Very depends on your biological rhythm individual, or “chronotype”.
Os chronotypes reflect the times when people naturally feel most awake or sleepy, and genetics plays an important role in shaping them. Research shows that sleep schedule is based, in part, on our genes, and that the chronotype is hereditary.
The chronotype is also changes throughout life: Teenagers tend to have later sleep patterns, while older adults often go to bed and wake up earlier.
Most people are neither extremely morning people nor extremely night owls, somewhere between the two extremes.
Os morning birds, often called “larks”they wake up early and feel awake shortly afterwards. They tend to get up early, even on the weekend, without needing an alarm clock. You evenings, or “mochos”feel more energetic later in the day and may perform better in the evening. Many people are left in the middle, in what are called “intermediate types“.
Chronotypes in everyday life
Studies often find differences between chronotypes. The types morning tend to report better academic results, including better performance at school and university, explains Christoph Randlerbiologist at the University of Tübingen, in an article in .
They also reveal less likely to use substanceswith lower rates of smoking, alcohol and drug use, and are more likely to exercise regularly.
The types eveningon average, have higher rates of burnout and have more likely to report worse mental health and physics. One explanation is chronic misalignment. Evening types most often live in Dissynchrony with work and school scheduleswhich leads to repeated sleep restriction, fatigue and stress accumulation.
Chronotype also appears to be related to broader behavioral tendencies, including differences in political attitudess, sense of responsibility, procrastination and adherence to schedules. These patterns reinforce the idea that the Chronotype Shapes Daily Behaviorand not just sleep.
One common belief is that adopting a morning routine will bring the same benefits seen in those who are naturally morning people.
However, chronotypes do not change easily. They are shaped by genetics and circadian biology. For many afternoon or intermediate types, waking up earlier than your natural rhythm can over time translate into sleep debt, lower concentration and worse state of mind.
This is the essential point: Waking up early alone does not create success. People tend to perform better when their daily schedules are aligned with their biological rhythms.
Morning people often thrive in systems structured around early startswhile evening people may have more difficulties not because they are less capable, but because reach peak alertness later.
The experiences of waking up early may seem effective at first. The initial impulse often reflects motivation and attention rather than a lasting biological change, similar to what happens after life changes like starting a new job. As routines stabilize, the mismatch between biology and schedule may become more difficult to sustain.
Biological clocks versus social clocks
A difference between natural rhythm and social time of a person is known as jetlag social. It reflects the extent to which everyday life takes people away from their biological clock.
Social jetlag has been linked to worst academic performance and lower well-being. Living out of sync with natural sleep patterns has also been linked to higher rates of diseases such as diabetes, high blood pressure and obesity. Force an early awakening it can worsen this lag in some people, especially in the afternoon types.
Some studies suggest that morning workers have a career advantage. These results are often interpreted as proof that morning routines drive success.
The most likely explanation is structural. Modern societies are organized around early bird hours. When biological rhythms coincide with work and school schedules, performance is easier to maintain, which creates a context where morning types seem to have an advantage.
Rather than imposing early morning routines, the more useful question is to understand how identify your own rhythm and work accordingly.
Or chronotype is just one of the factors that shape performance, along with the environment, opportunities and personal circumstances, but understanding it can help people make more realistic decisions about their daily routines.
Owl or lark?
Understanding your chronotype starts by observing your natural sleep patterns. Keep a sleep logwriting down the times you go to sleep and what you wake up to on workdays, weekends and vacations. You free dayssuch as weekends and holidays, often reveal their natural rhythm.
Also record mood and energy levels to understand when you feel most awake. Notice how long it takes to fall asleep. Less than 30 minutes suggests a bedtime that suits you well. More than an hour may indicate a later chronotype.
Observe how you react to the time change in early spring. If early mornings continue to feel natural after the change, you may have a more morning bias.
Changing the chronotype is difficultbut small adjustments can help. Instead of trying to wake up earlier straight away, try going to bed a little earlier, including on the weekend. If you fall asleep without difficulty, you can gradually shift your sleep rhythm earlier.
A exposure to natural light in the morning and reducing the use of screens in the late afternoon and evening can also promote an earlier sleep schedule. Still, the biology imposes limits.
The real productivity advantage is not about waking up earlier, but about design adjusted routines to the way the brain and body actually work, concludes Randler.
