일본 총리, 하루 3시간 이하로 나라 다스린다

Can a person really run a country on almost no sleep? Japan's prime minister Sanae Takaichi recently opened up about her sleep habits, and the answer she gave surprised many people around the world.

Takaichi says she typically sleeps between zero and three hours per night. For most of us, that sounds impossible. A full night of sleep usually means seven to nine hours. Yet Takaichi claims she manages her demanding job with just a fraction of that time. She is not alone in this habit—many world leaders report sleeping very little. But her honesty about the extreme deprivation sparked serious conversations about whether this is sustainable or simply unhealthy.

Sleep scientists have strong opinions on this topic. They explain that sleep is not a luxury; it is essential for the human brain and body. During sleep, your brain consolidates memories, processes emotions, and repairs itself. Without enough sleep, decision-making suffers. Reaction time slows down. Creativity and focus fade. For someone leading a nation, these consequences could matter a great deal. Researchers worry that leaders operating on minimal sleep may make poor choices under pressure.

Interestingly, some people claim they need less sleep than others. Scientists call these individuals "short sleepers." Genetic variations may allow a small percentage of the population to thrive on five hours or less. However, most of us cannot function well on three hours, no matter how determined we are. The difference between a rare short sleeper and someone simply ignoring their body's needs is significant.

Takaichi's revelation also reflects cultural attitudes about work and dedication. In Japan, overwork is sometimes seen as a sign of commitment and loyalty. Long hours and minimal rest have been normalized in many workplaces. Yet this culture is slowly changing. Japan's government now encourages better work-life balance and recognizes that burnout damages productivity and health.

The larger question remains: should we admire leaders who sacrifice sleep for their jobs, or should we worry about them? Most sleep experts say the answer is clear. A leader who is well-rested makes better decisions. A leader who is exhausted puts their nation at risk. Perhaps the real strength is knowing when to rest—and having the courage to prioritize sleep over endless work.

So what do you think? If you were leading a country, would you follow Takaichi's path of minimal sleep? Or would you insist on getting proper rest? The answer might say something important about what we truly value in our leaders.
