일본 총리, 하루 3시간 이하의 수면으로 국가 운영

What if your boss said she never sleeps? Japan's prime minister Sanae Takaichi recently told people she sleeps only zero to three hours each night. That is a very short time. Many people in Japan and around the world were shocked to hear this.

Takaichi is the leader of Japan. Her job is very hard and very important. She makes big decisions every day. She meets with many people. She reads many papers about politics and money. Running a country needs a lot of work. But does it need to cost your sleep?

Sleep is very important for your brain and body. When you sleep, your body fixes itself. Your brain puts memories in the right place. Your body makes strong cells. When you do not sleep enough, you feel tired. You cannot think clearly. You make more mistakes. Doctors say most people need seven to nine hours of sleep every night.

But Takaichi says she does not need much sleep. Some people think she is very strong. Other people worry about her. They ask: Can she really do her job well if she does not sleep? What happens to her body and mind?

This story makes us think about work and rest. In some countries, people think long work hours show you are very good at your job. But science says rest is important too. You cannot work well if you are tired. Maybe Takaichi is different. Or maybe she will learn that sleep is not lazy — sleep is necessary.

What would you do? Could you work with only three hours of sleep? Do you think leaders need more rest, or less?
