Study of how excessive sleep may lead to early death

None of them were the same; instead, they were separate and categorized based on income levels across seven different geographic regions. These selected countries were then subject to further classification based on the gross national income per capita as provided from the World Bank classification. Nations such as UAE, Canada, Sweden, and Saudi were categorized as high-income countries, while Columbia, Iran, China, Chile, Argentina, Brazil, Palestine, Philippines, Malaysia, Turkey, Poland, and South Africa were labeled middle-income countries. Low-income countries consisted of Pakistan, India, Bangladesh, Zimbabwe, and Tanzania.

It was observed that individuals who slept for more than 6 hours at night adding with few hours of rest in the day had elevated chances of suffering early mortality or death and victim of heart diseases as compared to those who slept for a bare minimum of fewer than 6 hours in a night.
