Why waking up early may not be the productivity hack you think
Waking up early has long been seen as a habit of successful people. Yet science shows the morning grogginess many feel—called sleep inertia—can linger for hours. This sluggishness happens because the brain starts the day cooler, only warming to its best working temperature later.
Around 1900, early rising was widely viewed as a virtue tied to discipline and hard work. The Protestant work ethic reinforced this idea across social classes in Western societies. Today, the habit still carries prestige, especially in corporate cultures that favour 'larks'—those who thrive in the mornings.
But research from 2019 highlights a growing debate. Morning people often gain advantages in education and careers, while 'night owls'—those genetically wired to stay up late—face systemic bias. Their creativity, studies suggest, peaks later in the day. Some well-known figures have harnessed early hours for productivity. Writer Toni Morrison woke before dawn to write while her children slept. Others, like Paul McCartney, found inspiration in dreams just after waking—the melody for *Yesterday* came to him this way.
The shift in perception reflects a tension between tradition and biology. While early rising still signals discipline in many workplaces, science now recognises that natural sleep patterns vary. For some, the quiet of dawn sparks creativity, while others struggle with a brain not yet at full speed.
