Based on the information provided, it's more accurate to rephrase the question to: "Which countries are considered the worst for sleep?" The references do not suggest a country literally never sleeps, but highlight specific nations with significant sleep issues.
According to the provided reference, South Korea and Japan are the countries considered to have the most trouble getting good sleep.
Here's a breakdown:
| Country | Sleep Issues |
|---|---|
| South Korea | Ranked among the world's worst for getting a good night's sleep. |
| Japan | Ranked among the world's worst for getting a good night's sleep. Also, issues related to karoshi are documented, highlighting the severe consequences of sleep deprivation. |
The issue in Japan is severe enough to be linked to the phenomenon of *karoshi*, or death from overwork, which includes a lack of sleep as a significant contributing factor. This shows the scale and seriousness of sleep deprivation in Japan.
It's important to note that this doesn't imply other countries don't have sleep issues, but these two are specifically highlighted as having particularly poor sleep habits or outcomes.
