Do you open your eyes a few minutes before your alarm goes off? This is not luck, but a biological phenomenon that is well known to researchers.
A well-regulated internal clock
According to the National Institutes of Health, the human body functions on a circadian rhythm, a roughly 24-hour biological clock that regulates sleep, appetite, body temperature, and many other functions. If you wake up at the same time every day, your brain anticipates the wake-up signal and adjusts the release of certain hormones.
The key role of cortisol
A few hours before your usual wake-up time, your body begins to produce more cortisol, a hormone that prepares you for waking up. This gradual increase helps you wake up naturally, sometimes just before your alarm clock rings.
A mechanism reinforced by habit
The more regular your waking rhythm, the more accurately your internal clock works. This phenomenon explains why some people wake up at the same time on weekends as on weekdays, even after turning off their alarm clock.
How can you promote natural awakening?
Maintain consistent bedtimes and wake-up times.
Avoid blue light from screens before bedtime
Expose yourself to natural light in the morning
Reduce caffeine consumption late in the day
Waking up before your alarm clock is often a sign of a well-regulated biological clock. By maintaining a regular rhythm and paying attention to your sleeping environment, you can optimize this natural process and reduce your dependence on alarm clocks.
