Work Less, Achieve More: The Science Behind Shorter Workweeks

The idea that longer hours equal more work is deeply ingrained, but science tells a different story. Studies consistently show that productivity peaks at around 40 to 50 hours per week and then declines as exhaustion sets in.

Historical Lessons

Over a century ago, reducing shifts to eight hours and paying workers more led to doubled profits in a major car factory. Today, companies experimenting with six-hour days and four-day workweeks report improved health among employees, lower absenteeism, and higher productivity.

Energy Management Over Time Management

Rather than focusing solely on hours worked, managing your energy cycles—typically 90-minute bursts of focused work followed by breaks—maximizes performance and well-being.

One venture capitalist noted that productivity drops with every hour worked beyond 40 per week, leading to policies discouraging overtime and weekend work.

By valuing quality over quantity, you can achieve more while enjoying better health and balance.

Next, we’ll tackle the internal pressures that drive us to overwork and how to overcome them for sustainable success.
