On average, do you feel happier than 2.7 out of 10?? And does your country’s population score high as well? Good news! According to a new study, your community is happy enough to enjoy significant health advantages.
The study, published in Medical Frontier, found that countries with a Life Ladder score exceeding 2.7 out of 10—a global indicator of well-being—experienced markedly lower mortality rates from non-communicable diseases (NCDs) like heart disease, cancer, asthma, and diabetes.
These findings indicate that while happiness and health are interconnected, nations need to progress beyond this well-being threshold for citizens to fully realize these benefits.
For each 1% rise in well-being above the 2.7 threshold, deaths from non-communicable diseases (NCDs) declined by an average of 0.43%. This implies that even slight increases in happiness can result in tangible health improvements.
In the United States, where the average happiness score stands at 6.96, such an increase could translate to nearly 11,500 fewer NCD-related deaths annually.
“Happiness is not merely a personal feeling; it serves as a measurable public health resource,” stated Yulia Iuga, a professor at the University of Alba Iulia in Romania and the study’s lead author.
The research analyzed well-being data from 123 countries collected between 2006 and 2021, comparing NCD mortality rates among adults aged 30 to 70.
Researchers employed the Life Ladder, a global tool for assessing subjective well-being that asks individuals to rate their lives on a scale of 0 to 10, where higher scores represent greater satisfaction.
“You can think of the life ladder as a straightforward happiness scale from zero to 10, with zero indicating the worst life and 10 the best,” Iuga clarified. “An appropriate descriptor for the 2.7 threshold could be ‘barely coping.'” Currently, only one nation falls below this benchmark: Afghanistan, with a happiness score of 1.36. Meanwhile, Finland leads the world ranking with a Life Ladder score of 7.74, followed by Denmark (7.52) and Iceland (7.51).
Iuga noted that the findings suggest the benefits of happiness are likely to continue expanding indefinitely. “There’s no downside to being excessively happy,” she emphasized. “This study found no point at which the health benefits began to taper off or reverse.”
Iuga further indicated that policies aimed at enhancing population well-being can foster self-sustaining cycles of health improvement. In essence, better health boosts happiness, which in turn encourages further health gains.
