On World Sleep Day, new research reveals the socioeconomic impact of insomnia on global populations
Insomnia is the most common sleep disorder and exacts a significant toll on an individual’s mental and physical health, quality of life and productivity. But the consequences of insomnia go well beyond the individual, with cascading effects on families, employers and global economies.
Amid growing evidence that the condition is increasing globally, new research from RAND Europe, funded by Idorsia Pharmaceuticals Ltd, Switzerland and published on World Sleep Day 2023, reveals the societal burden and broad economic impact of insomnia, from countries within Western, Northern and Southern Europe as well as North America and Australia. Insomnia symptoms include difficulty falling or staying asleep or poor quality or non-restorative sleep.
The findings from the study show that chronic insomnia, which is defined as insomnia symptoms experienced at least 3 times per week for at least 3 months and impairment to daily activities, is associated with reduced productivity in the workplace due to absenteeism and presenteeism, resulting in the loss of an average of 44–54 working days per year and, consequently, a substantial loss to annual GDP. Additionally, the study describes the ‘hidden’ or intangible costs related to what individuals with insomnia would be willing to trade to avoid the negative consequences of this condition (i.e. the well-being loss).
Using a range of methodologies1, the researchers uncovered the following key findings:
While approximately half of all adults are expected to experience some insomnia symptoms across the countries studied, one in 12 adults (approx. 8%) suffer from chronic insomnia.
The annual economic cost of chronic insomnia due to productivity loss and in terms of gross domestic product (GPD) output, ranges from $1.8 billion in Portugal to $207.5 billion in the US. In terms of percentage of total GDP, this ranges from 0.64% in Austria to 1.31%, each, in the UK and Switzerland.
An individual suffering from insomnia would on average be willing to trade an estimated 14.0% of their per capita annual household income to recuperate the associated well-being loss. This translates to annual ‘hidden’ costs in the working-age population, ranging from $1.5 billion in Norway to $127.1 billion in the US, 3 which reflect the aggregated value that working-age adults with insomnia from each country would be willing to trade.
Study co-author, Dr Robert Romanelli, of RAND Europe said: “Understanding the broader societal effects of insomnia is crucial in identifying opportunities for scalable interventions designed to improve individual health, well-being and productivity of individuals. This would collectively benefit society as a whole. Unfortunately, insomnia is oftenunderdiagnosed, suggesting that many people are not getting the clinical support they need.”
Study co-author, Dr Wendy Troxel, of RAND Corporation said: “We have known for a long time how devastating chronic insomnia can be for public health and wellbeing, but this report adds critical findings demonstrating the significant, global economic costs of insomnia across the working age population.”
Among several recommendations for employers, policymakers and healthcare professionals, the study highlights: Workplace interventions to identify and mitigate the impact of insomnia, screening for the disorder to be incorporated into routine clinical visits and sleep health training for medical students and clinicians.

RIVERSIDE, Calif. -- Until recently, psychologist Kalina Michalska had never used community-based participatory research, or CBPR, in her work, but now she can’t imagine not using it.
CBPR, which dates to the early 1930s, is an intensive research approach that involves partnerships between researchers and community members throughout the research process, giving communities a voice in how the research proceeds and allowing them to make use of the findings more effectually.
The study led by Michalska, an ...
New Haven, Conn. — The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species — known as “good” bacteria — in the gut may enable medical interventions that promote gut and overall human health. In a new study, Yale researchers have uncovered a novel mechanism by which these bacteria colonize the gut.
Specifically, the Yale team discovered that one of the most abundant beneficial species found in the human gut showed an increase in colonization potential when experiencing carbon limitation — a finding that could yield novel clinical ...

The Tibetan Plateau, the highest and largest plateau above sea level, is one of the harshest environments settled by humans. It has a cold and arid environment and its elevation often surpasses 4000 meters above sea level (masl). The plateau covers a wide expanse of Asia—approximately 2.5 million square kilometers—and is home to over 7 million people, primarily belonging to the Tibetan and Sherpa ethnic groups.
However, our understanding of their origins and history on the plateau is patchy. Despite a rich archaeological context spanning the plateau, ...
DURHAM, N.C. – A key feature of the severe allergic reaction known as anaphylaxis is an abrupt drop in blood pressure and body temperature, causing people to faint and, if untreated, potentially die.
That response has long been attributed to a sudden dilation and leakage of blood vessels. But in a study using mice, Duke Health researchers have found that this response, especially body temperature drop, requires an additional mechanism – the nervous system.
Appearing online March 17 in the journal Science Immunology, the study could ...
Everyone is familiar with glass—from putting on eyeglasses, pushing open the window, standing in front of a mirror, to holding a water glass. Glass is ubiquitous in nature and essential to human life.
But the widespread use of persistent, non-biodegradable glass that cannot be naturally eliminated causes long-term environmental hazards and social burdens.
To solve this problem, a research group led by Prof. YAN Xuehai from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences has developed a family of eco-friendly glass of biological origin fabricated from biologically derived amino acids or peptides. The ...
LOS ALAMOS, N.M., March 17, 2023 — Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
“With the help of a quantum annealer, we demonstrated a new way to pattern magnetic states,” said Alejandro Lopez-Bezanilla, a virtual experimentalist in the Theoretical Division at Los Alamos National Laboratory. ...
LA JOLLA—(March 17, 2023) Cancer treatments have long been moving toward personalization—finding the right drugs that work for a patient’s unique tumor, based on specific genetic and molecular patterns. Many of these targeted therapies are highly effective, but aren’t available for all cancers, including non-small cell lung cancers (NSCLCs) that have an LKB1 genetic mutation. A new study led by Salk Institute Professor Reuben Shaw and former postdoctoral fellow Lillian Eichner, now an assistant professor ...
DURHAM, N.C. – A research team at Duke Health has identified a set of biomarkers that could help distinguish whether cysts on the pancreas are likely to develop into cancer or remain benign.
Appearing online March 17 in the journal Science Advances, the finding marks an important first step toward a clinical approach for classifying lesions on the pancreas that are at highest risk of becoming cancerous, potentially enabling their removal before they begin to spread.
If successful, the biomarker-based approach could address the biggest impediment to decreasing the ...
UNIVERSITY PARK, Pa. — A new discovery, reported in a global study that encompassed more than a decade of research, could lead to the breeding of corn crops that can withstand drought and low-nitrogen soil conditions and ultimately ease global food insecurity, according to a Penn State-led team of international researchers.
In findings published March 16 in the Proceedings of the National Academy of Science, the researchers identified a gene encoding a transcription factor – a protein useful for converting DNA into RNA – that triggers a genetic sequence responsible for the development of an important trait enabling corn roots ...
